Its purpose was to study how a lagoon home development built on a salt marsh would affect the processes, functions, and conditions normally found in such an area. The specific site chosen is presently known as Village Harbour; however, at the time of the study, it was called Beach Haven West. It is located in Ocean County near Manahawkin, New Jersey. The investigation was multifaceted and was conducted from 1973 through 1977. The results of this study are presented in a two-part format. The first part is a two volume set which is titled "The Field Data". The data represent a compilation of the documents submitted by the principal investigators in fulf ill- ment of their project responsibilities. The purpose of these reports is to es- tablish data sets of the many components forming the estuarine system and to in- vestigate the individual units. The second part entitled "Analysis", draws upon selected portions of the field data to evaluate the effects of and the changes brought about by the lagoon development's presence. In assembling the two volumes of field data, certain guidelines were employed. The principal objective was the preservation of the intent and meaning of the orig- inal investigator. To accomplish this, the two volumes were organized as a compil- ation of the original research reports with a minimum of editing or modification. This was to ensure the integrity and logic of each report was retained as the author intended. In general, changes were made only to maintain a standard format. MM- jor changes were subject to the approval of the original authors. This guideline served to reinforce the direct connection between the report and the researcher who authored it. It also assured the scientific validity of the subsequent analy- sis. One consequence of this minimum change policy was the retention of the units system employed by the investigator. The problem of dealing in the British and metric systems concurrently was not deemed significant enough to warrant the ex- tensive changes required. Another guideline concerned the choice of documents in the field data volumes. if a number of reports were produced over the course of the investigation, the summary versions of the reports were included. If such superseding documents were unavailable, all available reports were appended and placed in the compilation. It is intended that the contents of the reports in the two field data volumes are the responsibility of the original authors. All manuscripts were subject to author review and approval prior to publication. The compilers of the field data assume responsibility only for the accurate transferal of text from the submitted original reports into the final format. Within the field data volumes, the taxonomic nomenclature follows Gosner (1971) for the estuarine benthic invertebrates and Bailey et al. (1960) for the fish. Note that the editors consider Nassarius obsoletus and Ilyanassa obso Zeta synonymous as are Phragmites cormmnis and Phragmites australis. Because the report sizes in the field data volumes varied considerably, two types of organization were employed. Those reports under 30 pages were written in a condensed format. Features such as separate title pages, table of contents, vii list of figures, list of tables, and separate acknowledgement and abstract pages (when requested), were used only in the larger reports. Condensation of the for- mat size was a primary objective in the smaller reports. Appendices are found in reports of all sizes and were employed to include (1) additional data not referred to in the report itself (see the Durand et al. and Good et al. reports); (2) raw data (see the Haskin and Ray report); and (3) figures and/or tables which would disrupt the text if placed in the body of the report because of the number of pages involved (see McClain et al. report). The specific organization of the field data contribution is as follows: 1) Users Guide 2) Order of Reports 3) Abstracts 4) Compiled Reports The order of the abstracts and the compiled reports followed as much as pos- sible their sequence of use in the analysis. This order follows. viii ORDER OF REPORTS Report No. 1 J. Durand, T. Sugihara, and ESTUARINE EVALUATION STUDY: PRIMARY C. Yearsley AQUATIC PRODUCTION AND NITROGEN. FOUR YEAR REPORT, 1973-1977. 2 R.

The abstracts cover discrete research areas and may draw upon more than one report in the col- lation for their basis. Abstract of the Primary Aquatic Productivity and Nitrogen: Four Year Report 1973-1977 study prepared by James Durand, Teruo Sugihara, and Charles Yearsley. This study compares aspects of stratification, the nitrogen cycle, and pri- mary production in a salt marsh system and an adjacent developed area near Mana- hawkin, New Jersey. Greater and more prolonged stratification is associated with the increased depths found in the lagoon development. The lower portions of the stratified water columns are subject to periodic anoxia and high ammonia-N levels. In all areas, the organic nitrogen fraction is the dominant nitrogen form found generally followed by ammonia-N, nitrate-N, and nitrite-N. In addition to nitro- gen standing stocks, processes such as nitrogen fixation, excretion, and ammonifi- cation were also studied and partial nitrogen budgets constructed. Primary pro- duction studies were done on the microflora associated with the marsh surface, intertidal zone, and benthic sediments as well as the phytoplankton. The phyto- plankton community is the greatest importance in both the natural and developed areas. Enrichment studies show the summer phytoplankton productive capacity to be nitrogen limited. High rates of production are also associated with the bulk- head algae community; however, its limited distribution minimizes its absolute total contribution. The productive capacity of the marsh surface edaphic algae community is directly related to light incidence. Consequently, the habitats with decreased grass canopy densities, like the Spartina alterniflora forms, have higher rates of primary production. In addition, the S. alterniflora short form occupies 60% of the marsh surface which magnifies the contribution of its edaphic algae to the total salt marsh productivity. As in the rest of this study, water column depth is stressed as a critical factor to production because of its rela- tionship to the size of the euphotic zone, turbidity, and the type of biological activity possible in the benthos. Abstract of the research on the production and decomposition dynamics of the salt marsh communities of the Manahawkin marshes performed by Ralph Good, Barry Frasco, Kay Smith, and William Brown. In the Manahawkin salt marsh-estuarine ecosystem, vascular plant primary production and the fate of this biomass were studied from 1973 to 1976. All phases of both processes were subsequently related to environmental parameters. Using the harvest method, estimates of annual aboveground net production (g dry wt'm-2' yr-1) are as follows: tall form Spartina alterniflora, 825-735; short form S. alterniflora, 444-574; S. patens, 535-618; and Distichlis spicata, 613-644. Below- ground production is generally about 5 times greater than aboveground. Total net primary production of short form S. alternatiflora on an energy basis is estimated at 16.0 kcal'm-2.yr-1, or 5.12 x 109 kcal for the entire marsh. These figures compared favorably with results for the world's most productive ecosystems. Standing crops of crude fiber, nitrogen-free extract, crude fat (aboveground ma- terial only), and crude protein (belowground material only) are shown to be a function of dry matter biomass. The accumulation of crude protein in aboveground xi material at the beginning of the growing season is thought to be a storage mechanism for potentially limiting nitrogen. Approximately 90% of the annual net primary production of the vascular plants remained at the end of the growing season. Based upon the analyses of plant material placed in litter bags and left on the marsh, a general decomposition pattern is described for the majority of study sites. Decomposition rates, however, vary with the type of plant material and the environmental regime. The amount of aboveground material in g dry wt'm-2.month-I entering the detrital food chain during the first year of de- composition is as follows: tall form S. alterniflora, 44 (6.0%); short form S. alterniflora, 20 (4.5%); and S. patens, 8 (1.5%). Additional biomass losses during the growing season are estimated from phenological studies, and are probably about 10% of the net aboveground production. Chemical analyses of de- compositional material reveal at nearly all study sites, percent crude fat de- creased and percent crude protein increased with time. The latter is attributed to colonization of the plant material by bacteria and fungi. The balance of production, decomposition, detrital export, accumulation, and incorporation into peat with seasonal tidal fluctuations and sea level changes are discussed in their relation to marsh stability. Abstract of the 1976 Submerged Salt Pond Vegetation study prepared by Dennis Slate. The purpose of the salt pool submerged vegetation study is to delineate the physical and chemical parameters which could be used to predict the presence or absence of Ruppia maritima and to measure the production of Ruppia in the salt pools of the Manahawkin marsh. Three parameters, depth, salinity, and surface area, accurately predicted 21 or 24 attempts. Ruppia occurs generally in ponds of large surface area, increased depth, and lower salinity. Peak Ruppia biomass occurs in late July - early August. The biomass estimates range from 0.04 to 79.60 g dry Wt'm-2 with an overall mean of 30.2 g dry wt-m-2. Abstract of the Benthic Invertebrates: Four Year Report 1973-1977 study pre- pared by Harold Haskin and Gary Ray. During July 1973 - February 1975, an inventory of natural or undisturbed creeks, partially disturbed waterways, and fully lagooned waterways in the Mana- hawkin, New Jersey area quantified the distribution of benthic invertebrate species within the study area. During July 1975 - March 1977, emphasis was placed on the study of distribution, population structure, growth, production, and food web relationships of the dominant benthic species. All sampling was done on a seasonal basis using a ponar dredge (0.05 m2). A total of 185 species were collected. The two major dominant species are Ampelisca abdita and Streblospio benedicti. These two account for approximately 60 and 9% of all the organisms collected, respectively. The 20 most numerous species account for approximately 90% of the total collection. Of the taxonomic groups, the Crustacea are the most numerous, followed by the Polychaeta and the Mollusca. Total species listings for each waterway type are nearly identical; however, species in the dredged and partially disturbed waterways were lost and replaced at a greater rate than in the natural creeks. Numbers of individuals and biomass xii estimates are inversely related to degree of development or disturbance. The creeks have 9 times the individuals and 25 times the biomass of the lagoon com- munity. Species distribution is apparently affected by hydrographic factors, sediment characteristics, and distance from the bay. Seasonal fluctuations in species, number of individuals, and biomass seem related to reproductive pat- terns of the dominant species and also to predation pressure. Production for the natural creek and lagooned waterways is estimated at 3.0 and 0.3 kcal-m-2- year-1, respectively. Abstract of the research on surface invertebrate populations in the Cedar Run area performed by Fred Ferrigno, Lee Widjeskog, Earl Tomlin, and J. Richard Trout. A preliminary study was conducted during August 1974 on the marsh surface invertebrate populations inhabiting 10 major cover types within the Cedar Run marsh evaluation study area. Point and interval estimates of the population densities within each cover type as well as total yield for the marsh complex were obtained for the following invertebrates: Modiolus demissus, Melampus bi- dentatus, Uca pugnax, Philoscia vittata, Orchestia grillus, ants, true bugs, crickets, grasshoppers, leaf-hoppers, and spiders. The most prevalent inverte- brates in terms of density and frequency of occurrence are Melampus, Philoscia, leaf-hoppers, Orchestia, and the spiders (in decreasing order of importance). These account for approximately 99% of the total yield (6,327,992 organisms, SD = 456,175) from the study area. About 96% of this total marsh population occurs within the extensive Spartina alterniflora (short form) and S. patens covers types. Invertebrates are scarce in stands of Phragmites australis, Scir- pus olneyi, and Panicum virgatum, and also in the incompletely lagooned area at Popular Point. Abstract of the 1976 Manahawkin Bay - Little Egg Harbor System: Finfish Study; Physical-Chemical Study' and Use Study prepared by John McClain, John Makai, and Peter Himchak. The purpose of the finfish study is to inventory the fish inhabiting the Manahawkin Bay - Little Egg Harbor system. The combined data of all the collec- tion methods (seine, trawl, and gill net) indicate the five most numerous species in decreasing order are the bay anchovy, the Atlantic silverside, the fourspine stickleback, the mummichog, and the tidewater silverside. Together they com- prise 80% of the total catch. Altogether 66 species of finfish were collected. The purpose of the physical-chemical study is to describe the Manahawkin Bay - Little Egg Harbor system in terms of its morphology, biota, and physico- chemical factors. Water quality in the system is good. In general, reduced oxygen levels are not found in the bay but are found in some of the creeks and especially in the lagoons. The dissolved oxygen levels in the lagoons are mani- festations of temperature stratification. The bay lacks both temperature and salinity vertical gradients. Horizontal salinity gradients and seasonal salin- ity variation are greatest in the creeks. The data indicate high coliform counts of unknown origin in certain areas (most of these areas were in the de- veloped sites). DDT, DDT metabolites, and certain heavy metals are present in animal tissue samples with higher levels found in the sediments tested. xiii The purpose of the use study is to determine the ways in which the Mana- hawkin Bay - Little Egg Harbor system is used by man. During the first study period (July 1973 - February 1974), it is estimated over 1.58 x 105 man-days of activity occurred in the study area with a resulting harvest in excess of 4.4 x 105 fish, 1.4 x 107 shellfish, and 300 waterfowl. Between June 1974 and May 1975, excluding November and December 1974, an estimated 2.3 x 105 mandays of activity produced a harvest of over 4.5 x 105 fish and over 1.9 x 107 clams. Abstract of the 1978 Analysis of the Fish Forage Base in the Little Egg Harbor Estuary study prepared by Patrick Festa. The purpose of this study is to identify the forage base and the allocation of this forage base among the Little Egg Harbor fish through stomach contents analysis. The forage base consists of 142 taxa which support at least 64 fish species. The trophic relationships present are complex because of the flexible dietary habits of the fish surveyed (55 species). Forage populations of partic- ular importance include the class Polychaeta, the order Calanoida, the suborder Gammeridea, the order Mysidacea, the infraorder Panaeidae, and the class Osteich- thyes. Some of the food chain associations indicated are Mercenaria-winter flounder; Cymadusa-pipefish; and calanoid copepod-sand lance-striped bass. The utilization of the forage base is analyzed in terms of use of a given forage item and also in terms of forage items consumed by a given fish species. Habi- tat area and seasonal aspects are also examined. Abstract of the 1977 Rodent Populations study prepared by Robert Bosenberg. Trapping of the rodents on the Cedar Run marsh was conducted periodically from April 1975 to June 1977. Total trapping effort using both live and killing traps amounted to 18,610 trap nights. Rodent species captured include the meadow vole (Microtus pennsylvanicus), muskrat (Ondatra zibethica), house mouse (Mts musculus), Norway rat (Rattus norvegicus), and the meadow jumping mouse (Zapus hudsonius). Microtus was the only mouse species captured in sufficient numbers to permit population density estimates. Peak densities of this species occur in July. Densities are greater in the incompletely lagooned section than in either the mosquito-ditched or natural marsh areas. Population densities are similar for the latter two sections. Densities within different vegetation cover types are related to the marsh alteration type in which they occur. A significant decline in Microtus numbers occurred in the incompletely lagooned area due to the effects of Hurricane Belle. The relation between Microtus populations and topographic relief, cover effects, predation, availability of nesting sites, and food resources are discussed. Muskrats are found to be restricted to the Scirpus-dominated vegetation located near the marsh-upland ecotone. The average number of huts observed in November of 1975 and 1976 was 21.5. Estimates of muskrat density for the area of marsh bordering and upland exceed five animals per hectare, and the total population for the Cedar Run study area probably exceeds 114 individuals. Due to the low capture success for the Norway rat, no reliable population estimates are possible. xiv Abstract of the 1976 Wildlife Indexes: Avian Density and Diversity study pre- pared by Joseph Penkala and Joseph Sweger. Bird censuses were conducted during the spring and fall migration periods within the following major vegetational associations of the Cedar Run marsh: up- land-marsh ecotone, Iva frutescens - Spartina patens, S. alternifiora, and the marsh interface with Cedar Run and Little Egg Harbor. Six visits were made during the period 20 April - 8 August 1975 and the line transect - mean flushing distance method used to determine the diversity and density of the avifauna. A total of 976 birds comprised of 87 different species were observed during the study period. Species which are typically considered to be summer residents are most prevalent. Sharp-tailed sparrows have the highest density of any species, followed by the red-winged blackbird and barn swallows. The laughing gull is the most abundant of the larger species. Reliable density estimates of most species are not possi- ble due to their infrequent occurrence. The S. alterniflora habitat accounts for the greatest number of birds observed and has the highest species diversity, averaging 68.3 individuals and 17 species observed per visit. The upland-marsh ecotone has the lowest diversity and density. Abstract of the research on bird nesting in the Cedar Run area performed by Lee Widjeskog, Fred Ferrigno, and J. Richard Trout. During August 1974, nine major vegetation cover types of the Cedar Run marsh study area were surveyed to determine the species and density of nesting birds. Point and interval estimates of the number of nests for each species within a cover type as well as estimates of the total number of nests for each cover type and for the entire marsh were obtained. A total of 149 nests were actually observed, and the estimated number for the entire marsh is 2,739.5 (SD = 361.0). Nesting spe- cies, in decreasing order of importance, include the sea-side and sharp-tailed sparrows (Ammospiza maritima and A. caudacuta), clapper rail (Rallus longirostris), willet (Catoptrophorus semipalmatus), long-billed marsh wren (Telmatodytes palus- tris), red-winged blackbird (Agelaius phoeniceus), and the black duck (Anas ru- bripes). Sparrows account for 64% of the estimated total. Nests occurring with- in the extensive areas of short form Spartina aZternifZora and S. patens account for 44% (1,213.9 nests) and 40% (1,099.6 nests), respectively, of the total marsh estimate. Although the density of clapper rail nests is high (13.29 nests'ha-1) in tall form S. aZterniflora, the overall importance of this cover type is mini- mized by its small areal contribution. Very little nesting occurred in stands of Scirpus olneyi, Panicum virgatum, or Distichlis spicata, and no bird species were observed to be utilizing either Phragmites australis or dredge spoil areas. Abstract of the 1974 Wildlife Indexes: Waterfowl Use and Harvest study prepared by William Shoemaker and Fred Ferrigno. During the fall and winter of 1973-74, waterfowl utilization and harvest data were obtained for the Cedar Run study area. Monthly aerial waterfowl counts were carried out from September to January. Hunter counts and bag checks were conduc- ted on Saturdays and one day of each week from October to January. Waterfowl populations in the immediate study area increase from 800 in September to a maxi- mum of 3,200 in December with a grand tally of 9,270 birds. This represents an increase from 1.46 to 5.86 birds per hectare of marsh. Black ducks are the most xv abundant, accounting for 35.3% of the total. Greater and lesser scaup are next in importance (20.5%). Within the surrounding ecosystem of Little Egg Harbor and its bordering salt marshes, the waterfowl population increases from 1,600 in Sep- tember to 20,000 in December, with a total count of 50,050 birds. Dominant spe- cies are the brant (21.8%), greater and lesser scaup (21.0%), black ducks (19.2%), and bufflehead (15.0%). Hunter use of the study area amounts to 874 man-days and 1.61 hunters per hectare of marsh for a total harvest of 2,407 waterfowl. Hunter success was 2.65 birds per hunter-day and 4.4 waterfowl per hectare of marsh. Diving ducks, primarily the scaup, are the preferred species. The greater scaup accounts for 76.8% of the total estimated harvest. These results demonstrate the Cedar Run marsh and adjacent bay to be a prime wintering area for waterfowl and also one with a considerable recreational value in terms of hunter use and success. Abstract of the 1974 and 1975 annual reports submitted on the Recreational Use of New Jersey's Wetlands by New Jersey Citizens prepared by James Applegate, Stephen Salmore, and John Blydenburg and James Applegate and Stephen Salmore, respectively. The primary objective of this study is to quantify the recreational benefits provided by New Jersey's wetlands to New Jersey residents. Univariate analysis indicates wildlife observation is the most popular salt marsh activity in which 15% of the New Jersey population participated. It is followed by crabbing (12%), picnicking/other (12%), fishing (10%), clamming (5%), and hunting (3%). Subse- quent cluster analysis divided the salt marsh users into grouping which could be combined into more inclusive categories. The activity categories chosen were extractive (fishing, hunting, crabbing, and clamming), appreciative (wildlife observation and picnicking/other), and nonexclusive (occasional participants but not exclusively in one activity). Of the approximately 19% of the New Jersey population which utilized the wetlands (under this analysis), 6.6, 5.6, and 7.2% belong to the appreciative, nonexclusive, and extractive categories, respectively. Other more restrictive groupings were examined as were the origin of the partici- pants in the various activities and man-day estimates of marine environment use. The estimated means of man-days of recreation (in millions of man-days) provided by crabbing, estuary fishing, ocean fishing, surf fishing, and clamming are 2.5, 2.0, 1.7, 1.1, and 1.0, respectively. Abstract of the Estimates of the 1975 Sport Harvest of Marine Fishes prepared by Stephen Sterner and James Applegate in 1976. Utilization of the stocks of bluefish, weakfish, fluke, white perch, striped bass, mackerel, whiting, cod, pollack, winter flounder, and tuna were estimated for either the 1 January - 1 June 1975 period for the 1 July - 20 December 1975 period. These estimates were referenced to the type of fishing done (ocean, river/bay, or surf) and who the fishing was done by (those who fish 10 days or less annually or those who fish more). During the 1 January - 1 June 1975 period estimates were made on the striped bass, mackerel, whiting, cod, pollack, winter flounder and weakfish harvests. Winter flounder (1.62 x 105 fish), mackerel (1.19 x 103 fish), and striped bass (9.9 x 103 fish) lead the combined fishing effort (for both types of fishermen) for the bay/river, ocean, and surf fishing categories, respectively. xvi During the 1 July - 20 December 1975 period estimates were made on the blue- fish, weakfish, striped bass, tuna, fluke, and white perch harvests. Bluefish, with a mean combined catch of 3.44 x 105 are taken most frequently by ocean fisher- men. Striped bass (5.8 x 104 fish) dominate the surf fishing while fluke (1.85 x 105 fish) lead the harvest by bay and river fishermen. xvii 7. STUDIES OF THE MANAHAWKIN BAY - LITTLE EGG HARBOR SYSTEM: 1.

McClain, Jr. ABSTRACT The purpose of this portion of the project was to inventory the fishes in- habiting the Manahawkin Bay - Little Egg Harbor system. Eighteen seine, 21 trawl, and 8 gill net stations located in various creeks and lagoons as well as the bay itself were sampled for finfish. There were 66 species of fish in various stages of their life cycles collected during the sur- vey period. Water quality parameters of the following ranges were recorded: salinity, 1.0 to 31.8 �/oo; water temperature, -1.0 to 29.0�C; and dissolved oxy- gen (D.O.), 0.00 to 14.34 mg 02/1.

INTRODUCTION This is the final report of a survey of the fishes of the Little Egg Harbor - Manahawkin Bay system. Work was begun in July 1973 and concluded at the end of May 1975. See Figure 1 for a map of the area and Table 1 for a spe- cies list. The figures for this report (as well as the other two reports which form this submission from the Nacote Creek Research Station) are in Appendix A. Tables 1 through 90, which are associated with the following finfish report, are contained in Appendix B. METHODS AND MATERIALS Three types of fishing gear were utilized to sample fish in the system: gill net, seine, and trawl. The gill net used was an experimental monofilament model of the following dimensions: five panels 25 feet (ft) x 6 ft, one each of 0.50 inch (in), 0.75 in, 1.00 in, 1.50 in, and 2.00 in square mesh. Three seine types were used during sampling: a 25 ft bag seine 5 ft deep with a 5 ft x 5 ft bag, all 0.50 in stretch mesh knotless nylon netting; an 80 ft x 6 ft bag seine (0.50 in square mesh) with 6 ft x 6 ft x 6 ft bag of 0.375 in square mesh; and a 150 ft x 10 ft bag seine (0.625 in stretch mesh) with a 10 ft x 10 ft x 10 ft bag of 0.375 in stretch mesh. Trawling was done with a 16 ft semiballon trawl of the following dimensions: 16 ft head headrope, 19 ft footrope, body 1.50 in stretch mesh No. 9 thread, codend 1.25 in stretch mesh No. 15 thread, innerliner 0.50 in stretch mesh No. 63 thread knotless nylon; doors 24 in x 12 in x 1 in mahogany with 0.375 in nylon rope, 100 ft of rope on each door, doors weighing 15 pounds (lbs) each. A trawl 7.1 sample consisted of a tow by a 17 ft Boston Whaler for 5 minutes; warp length was adjusted for depth. Two tows were made at each station under normal condi- tions. The catch of each sample was counted by species and all fish were weighed and then measured for total length. Subsamples were taken when individual mem- bers of any species were so great as to make processing of the entire catch im- practical. These subsamples were counted, measured, and weighed, and the data developed was projected to reflect the total captured weight of the species. SEINING RESULTS Eighteen stations were sampled at various times during the survey (see Figures 1 and 2 for station locations and Table 2 for description). Tables 3 through 20 list sampling results by station and Tables 21 through 28 summarize the data on a seasonal basis as well. Forty-eight species of finfish numbering 25,662+ specimens were taken. Table 29 lists the 10 most abundant species, their number and percent of total seine catch. Utilizing three seines, 278 hauls were made: 193 hauls with the 25 ft seine (catch per haul or c/h = 33.4 specimens); 51 hauls with the 80 ft seine (c/h = 77.5 specimens); 34 hauls with the 150 ft seine (c/h = 447.9 specimens). Seasonal c/h for the five most abundant species is given in Table 30. Following is a seasonal account of seine results. Summer There were 43 species of finfish collected during the summer, 37 species in 1973, and 38 in 1974; 31 species appeared in both summer samples. Fifteen were taken only in the summer; most of these were strays from the south such as the crevalle jack, mojarra, permit, and filefish. The c/h was 31.6 specimens for the 25 ft seine, 29.6 for the 80 ft seine, and 635.3 for the 150 ft seine. Three forage species made up 81% of the total catch. The most abundant of these was the Atlantic silverside, followed by the bay anchovy, and the four- spine stickleback. These species were taken at all three types sampling sta- tions - bay, creek, and lagoon. The spot ranked fourth, most of those collected being young of the year. The summer catch accounted for 96% of all spot. They occurred at all three types of sampling stations. Most were taken in the 150 ft seine. The c/h was 30.8 specimens. The c/h for the 25 ft and 80 ft seines was 0.3 and 0.1, respectively. The tidewater silverside ranked fifth. They were taken at creek and lagoon stations. Most (82%) were collected in salinities less than 18 0/oo. The c/h was 5.5 specimens for the 25 ft seine and 7.9 for the 80 ft. None were taken with the 150 ft seine, which was used primarily at bay stations. Other species with 100 or more specimens taken during the summer were: banded killifish, mummichog, northern pipefish, and silver perch. The summer catch of mummichogs was only 9% of the total mummichog catch. Conversely, the other three species were taken primarily in the summer. 7.2 Fall Twenty-nine species were caught in the fall, 26 in 1973, and 15 in 1974; 11 species were common to both years. The c/h was 39.1 specimens for the 25 ft seine, 55.7 specimens for the 80 ft, and 437.4 specimens for the 150 ft. Four forage species made up 86% of the fall catch. Three of these, the Atlantic silversides, tidewater silversides, and the mummichog, appeared throughout the system. The fourth, the bay anchovy, was collected at only four stations. One haul at station 9 (Lagoon 24) yielded 88% of the fall anchovy catch. The mummichog and tidewater silverside were most abundant in the fall, 35% and 67% of their total seine catches occurred then. Fifth in abundance was the fourspine stickleback which made up 2.8% of the fall catch. They were taken in all sampling regions. The c/h was 19 specimens for the 150 ft seine and 0.5 for both the 25 ft and 80 ft seines. Another species making up more than 2% of the catch was the banded killi- fish. They were collected in upper Mill Creek and Lagoons 77 and 100 which branch off the creek. Salinities at the time of capture ranged from 1.00 to 7.09 0/00. The 150 ft seine was not used at these stations. The c/h was 4.6 specimens for the 25 ft seine and 0.1 for the 80 ft seine. Two other species numbered over 100 specimens. The naked goby was collected primarily at creek stations; c/h was 9.4 specimens for the 150 ft seine and less than 0.5 for both the 25 ft and 80 ft. The rainwater killifish was taken in all three sampling regions, however, the largest numbers were associated with lagoons with natural banks. The c/h was 0.4 specimens for the 25 ft seine, 2.3 specimens for the 80 ft, and 2.6 specimens for the 150 ft. Winter There were 13 species taken in the winter, 10 in 1974, and 12 in 1975. Nine species occurred in the samples for both years. The c/h was 5.4 specimens for the 25 ft seine, 17.2 specimens for the 80 ft, and 177.5 specimens for the 150 ft. The fourspine stickleback made up 52% of the winter catch. It appeared at all sampling station types, however, most of the fish were taken in the bay. The c/h was 1.6 specimens for the 25 ft seine, 2.2 specimens for the 80 ft seine, and 160 specimens for the 150 ft seine. Only two hauls were made with the 150 ft seine during the winter. Second in abundance was the Atlantic silverside. Most were collected at station 20 (Lagoon 07) in the winter of 1975. The c/h was 2.8 specimens for the 25 ft seine and 0.1 for the 80 ft. The winter catch, while ranking second for the season, accounted for only 2% of the total Atlantic silverside catch. The above species combined with the mummichog, sheepshead minnow, and the tidewater silverside made up 93% of the winter catch. The mummichog and tide- water silverside were the least abundant in the winter; c/h with the 80 ft seine was 7.5 specimens and 1.7 specimens, respectively. 7.3 Spring Twenty-six species were taken during the spring. The c/h was 33.5 specimens for the 25 ft seine and 390.4 for the 150 ft; the 80 ft seine was not used. Five species made up 92% of the spring catch. In descending order of abundance, they were fourspine stickleback, mummichog, Atlantic silver- side, bay anchovy, and tidewater silverside. The fourspine stickleback accounted for 35% of the catch. It was collected at three stations, two in the bay and one lagoon. Station 2, a bay station, accounted for 98% of the catch. The c/h was 204 spec- imens for the 150 ft seine and 0.1 for the 25 ft. Mummichogs were captured at all three sampling station types. They made up 28% of the spring catch and 51% of the total mummichog catch. The c/h was 8.8 specimens for the 25 ft seine and 114.3 for the 150 ft. The Atlantic silverside was taken at five stations. This catch accounted for 8% of all Atlantic silversides taken and 19% of the total spring catch. The c/h was 13.8 specimens for the 25 ft seine and 28 specimens for the 150 ft. Of all bay anchovies, 5% were collected in the spring. They were taken at nine stations throughout the system; c/h was 2.7 specimens for the 25 ft seine and 18.6 for the 150 ft. Tidewater silversides were taken at all three types of sampling stations, but most were collected at lagoon stations. The c/h was 3.3 specimens for the 25 ft seine and 1.0 for the 150 ft. Blueback herring ranked sixth, making up 2% of the spring catch. All were collected at lagoon stations and appeared to be 1 year old. Atlantic menhaden were seventh in abundance. All except one were taken at lagoon stations, and most were young of the year. TRAWL RESULTS Tables 31 through 59 list sampling results by station. See Figures 1 and 2 for station locations and Table 60 for station descriptions. The 10 most abundant species, their number, and percentages of the total trawl catch are given in Table 61. All trawling efforts (427 hauls) yielded 9,730+ specimens of 54 species. Seasonal c/h for these species is given in Table 62. Following is a seasonal account of trawl results. 7.4 Summer One hundred fifty-three hauls resulted in the collection of 4,218+ specimens of 41 species. Thirty-one species were taken in 1973 and 30 in 1974; 23 species appeared in both years. Overall c/h for the summer was 27.6 specimens. Seven species numbered over 100 specimens. Together they made up 92% of the trawl catch. They were bay anchovy (47%), spot (22%), fourspine stickleback (12%), oyster toadfish (3%), silver perch (3%), winter flounder (3%), and weakfish (2%). The bay anchovy was abundant in the bay and creeks; none were taken in the lagoons. The c/h was 13.2 specimens in 1973 and 12.5 in 1974. Spot were taken at the bay, creek, and lagoon stations; most were young of the year. The c/h was 5.6 specimens in 1973 and 6.9 in 1974. During the summer, 88% of the specimens were captured with the remaining 12% caught in the fall. All but 24 fourspine sticklebacks were taken at bay stations. The c/h for 1973 was 2.6 and 4.0 for 1974. Of all oyster toadfish, 73% were collected in the summer; the c/h was 0.8 specimens in 1973 and 1.0 in 1974. Winter flounder ranked sixth with 116 specimens; 78% of these were taken at station 5 near Barnegat Inlet with 56 specimens captured in two tows on 14 August 1973. The c/h was 0.7 specimens in 1973 and 0.8 in 1974. Weakfish were seventh in abundance with 107 specimens taken this season constituting 80% of the total weakfish catch. All but one of these were young of the year. The c/h was 0.9 specimens in 1973 and 0.4 in 1974. Other species collected primarily during the summer include American eel (59%), black sea bass (60%), bluefish (71%), northern pipefish (51%), summer flounder (63%), and tautog (41%). Fall Thirty-two species of fish were taken in 1973 and 14 species in 1974 with 12 species common to both years. In total 1,658 specimens were captured during both years. The c/h was 16.0 specimens for 1973 and 7.5 for 1974. Combined c/h was 13.6 specimens. The difference 7.5 between the 2 years was partially due to boat engine failure during most of November and all of December 1974. Bay anchovy, fourspine stickleback, mummichog, spot, and tidewater silverside numbered over 100 specimens. These species made up 70% of the fall catch. The mummichog ranked first in abundance with 330 specimens; 324 of which were collected in one haul at station 15 in December 1973. Appar- ently, the trawl was pulled through a school during retrieval. Six were taken at station 16 on the same day. The c/h was 2.7 specimens. Second in abundance was the bay anchovy. They were taken at all three sampling station types, bay, creek, and lagoon. The c/h was 1.2 in 1973, 5.6 in 1974, and 2.3 overall. The fourspine stickleback was third with 278 specimens. It also appeared at all sampling station types. The c/h was 3.2 in 1973; the overall c/h dropped to 2.3 as no specimens were collected in 1974. Spot were taken in October only, 123 in 1973 and 4 in 1974. Of the 14 stations sampled both years, spot appeared at 11 in 1973 and none in 1974. Lower water temperatures in October 1974 may have been the cause. Spot were collected at all sampling station types. The c/h was 1.5 in 1973 and 1.0 overall. The tidewater silverside ranked fifth with 120 specimens, all collected in 1973 with 118 of these taken in December. It was taken at three sta- tions, Thompson's Creek, Mill Creek, and Lagoon 100. Salinities at the latter stations were 13.48 and 16.48 �/oo, respectively. The c/h was 1.4 specimens in 1973 and 1.0 overall. Absence of the species in the fall of 1974 was possibly due to the fact that no trawling was done in December of that year. Three important commercial and recreational species captured in the fall were weakfish, white perch, and winter flounder. A total of 26 weak- fish were taken, 20 in October 1973 and 6 in October 1974. All appeared to be young of the year. White perch ranked sixth with 87 specimens. Except for three speci- mens taken in the bay, all white perch were collected in Mill Creek and two lagoon stations branching off the creek. Salinities at these stations ranged from 10.23 to 19.25 0/oo. Two white perch were taken at station 8 in the bay just off the mouth of Mill Creek and one was collected at station 10 just off the mouth of Cedar Run. Recorded salinities were 30.86 and 28.19 O/oo, respectively. These samples were collected on 5 December 1973. The c/h was 0.7 specimens overall. There were 70 winter flounder taken, ranging in age from young of the year to 5+ years. The c/h was 0.6 specimens overall. 7.6 Winter In 60 hauls, 13 species numbering 790 specimens were collected. The c/h was 13.2 specimens overall. Due to weather conditions and engine prob- lems, no sampling was conducted in January or February 1975. The fourspine stickleback accounted for 49% of the winter catch with 300 of 388 specimens netted at station 25 on 27 February 1974. They appeared in all three sampling regions. The c/h was 6.5 specimens. Second in abundance was the tidewater silverside with 141 specimens; 92% were taken at station 15 on 15 February 1974. The recorded salinity was 12.97 0/oo. They were also taken at station 18 in February and March in salinities of 15.75 and 15.32 �/oo, respectively. The c/h was 2.4 specimens. Blueback herring ranked third with 69 specimens; 22 were collected at station 25 in February 1974 and 45 at station 11 in March 1975. All specimens appeared to be young of the year. The c/h was 1.1 specimens. There were 65 white perch taken, 14 in Mill Creek and 51 in Lagoon 77 off Mill Creek. Salinities ranged from 10.41 to 15.75 �/oo. These speci- mens ranged from young of the year to 9 years old. The c/h was 1.1 speci- mens. Winter flounder ranked sixth with 53 specimens; 8 specimens were col- lected in creeks and 45 in the bay. They ranged from young of the year to 4+ years. More than 60% appeared to be 4 years or older. Spring The 92 hauls made yielded 3,040+ specimens of 31 species. Sampling was carried out in June 1974 and April and May 1975. Spring provided the greatest seasonal c/h, 33.1 specimens. The high c/h was due to the abundance of the bay anchovy; 52% of the total anchovy catch was collected in the spring. Most of these were taken in Dinner Point and Westecunk creeks. The c/h in these creeks was 78.8 specimens; overall c/h for the spring was 26.6 specimens. Atlantic menhaden ranked second with 291 specimens, all collected in June 1974. This represents 92% of the total menhaden catch. Again, most (98%) were taken in Dinner Point and Westecunk creeks. The c/h in the creeks were 15.8 specimens; overall c/h was 3.2 specimens. All specimens were young of the year. The above species made up 90% of the total spring catch. The third most abundant species was the Atlantic silverside. The 65 specimens taken during the spring accounted for 35% of all the Atlantic silversides taken trawling. The winter catch was also 35%, with 20% taken in the fall, and IO/ in the summer. The c/h for the spring was 0.7 specimens. 7.7 Winter flounder ranked fourth with 55 specimens. Most of those captured in June were young of the year. Those collected in April and May ranged from 2 to 5 years old. The c/h was 0.6 specimens. GILL NET RESULTS Gill net stations are indicated by a G preceding the trawl or seine station with which they were associated (e.g. GT-2) indicates the gill net station lo- cated near trawl station 2 off Marshelder Island). Tables 63 through 70 list water quality data and fish taken at eight stations sampled during the second year of the study (June 1974 to July 1975). Tables 71 through 74 list the num- ber of each species taken seasonally at each station. Three gill net sets were made during the first year of the survey and the results are given in Table 75. Altogether, 614 specimens representing 21 species of finfish were taken. Two of these, the smooth dogfish and the striped bass, were taken only by gill net. The Atlantic menhaden was the most abundant species. The 310 specimens collected comprised 50% of the gill net catch. They were taken during the July through December and February through May periods at five stations. The bluefish ranked second, 78 specimens were taken constituting 13% of the catch. They appeared during the months of July through October and at seven stations. White perch ranked third, 73 specimens making up 12% of the catch. They were captured from December through May and at three stations, two of which were located in the Beach Haven West lagoon system. The four most abundant fish was the spot, 66 specimens constituting 11% of the catch. They were taken July through October and at six stations. The alewife ranked fifth in abundance. Twenty-seven specimens making up 4% of the catch were captured. They were taken in January and again in March through May and at two stations. COMBINED RESULTS There were 66 species of finfish taken in the study area. Table 76 lists the number of each species taken by each gear, overall rank, and the percent of the total catch each species comprises. Tables 77 and 78 summarize the spe- cies distribution as shown by the capture data for the seine and trawl, respec- tively. Table 79 describes the capture locations of selected species. Table 80 relates the seasonal occurrence of the finfish species sampled. Twenty- three species are represented by more than 100 specimens. The following is a short account of 13 of these. Bay Anchovy The bay anchovy is an euryhaline forage fish found primarily in estuaries and coastal waters. During the survey, 9,700+ specimens, comprising 27% of the total catch, were taken. 7.8 The catch was almost evenly split between seine (51%) and trawl (49%). They were collected at 13 of 18 seine stations and 18 of 21 trawl stations. The c/h was 1.2 specimens for the 25 ft seine, 17.7 for the 80 ft seine, 13.8 for the 150 ft seine,and 11.1 for the trawl. They appeared in the catch 9 months overall. Three were taken by trawling in March. During April through November, they were taken by both gear types. Bay anchovies were most abundant in the summer (July, August, September), 5,480 specimens constituting 55% of the total anchovy catch. The September catch ranked highest overall (3,218 specimens) and seining was the more effective method (2,394 specimens). May was the high month for the trawl catch with 1,650 specimens. Recorded water quality parameters at which anchovies were taken were: salinity, 2.20 to 31.22 �/oo; water temperature, 4.0 to 30.50C; and dissolved oxygen, 1.93 to 12.75 mg 02/1. Stomach analyses of 29 fish species taken in the area (Festa 1975) showed the bay anchovy to be an important diet item of the bluefish, summer flounder, and weakfish. Conversely, bay anchovy stomachs contained: fish eggs; polychaetes (Nereis sp. and Polydora sp.); Crustaceans (amphipods, isopods, tanaids,and Caridean shrimp); insects (Chironomidae larvae); and nematodes. Atlantic Silverside The Atlantic silverside is another important euryhaline forage species. It ranked second in abundance in the study area, 9,330 specimens comprising 26% of the catch. Seining accounted for 98% of the catch and trawling 2%. It was taken at 17 of 18 seine stations and 13 of 21 trawl stations. The c/h was 9.0 for the 25 ft seine, 21.6 for the 80 ft seine, 172.4 for the 150 ft seine and 0.44 for the trawl. Atlantic silversides appeared in all months in both types of gear. Most (57%) were captured in the summer (July, August, September) followed by fall (30%), spring (9%), and winter (2%). Water quality parameters recorded when Atlantic silversides were taken were: salinity, 1.00 to 31.81 �/oo; water temperature, 0.5 to 30.50C; and dissolved oxygen, 3.16 to 12.74 mg 02/1. Regarding the food web study, the only positive identification of the Atlan- tic silverside was in striped bass stomachs. However, Menidia sp. were found in bluefish and northern sennet. Other species taken in the study area and known to feed on Atlantic silversides are the summer flounder and weakfish. Atlantic silverside stomachs contained: polychaete remains; Crustaceans (amphipods, decapods, mysids, calanoids, and harpacticoids); nematodes; Hydrozoans; and diatoms. Fourspine Stickleback The fourspine stickleback ranked third overall. The 5,224 specimens taken constituted 14% of the total catch. Of these, 77% were taken by seine and 23% by trawl. They appeared at 15 of 18 seine stations and 18 of 21 trawl stations. 7.9 The c/h was 0.5 for the 25 ft seine, 0.7 for the 80 ft seine, 114.8 for the 150 ft seine, and 2.7 for the trawl. They were taken in all months of the year by both gear types. Most were taken in summer (48%) followed by spring, winter, and fall. Recorded water quality parameters at the time of capture were: salinity, 1.00 to 30.86 �/oo; water temperature, -1.0 to 29.0�C; and dissolved oxygen, 0 to 12.87 mg 02/1. Fourspines were utilized as food by the following species: Atlantic needle- fish, oyster toadfish, spotted hake, weakfish, and white perch. The fourspine stickleback fed on: fish eggs; annelids (polychaetes and oligochaetes); Crustaceans (amphipods and isopods); mollusks (gastropods and bi- valves); and Platyhelminthes (Turbellarians). Mummichogs Mummichogs (2,559 specimens) made up 7% of the total catch; 87% were collec- ted by seine, 13% by trawl, and 4 specimens by gill net. Of the 331 mummichogs taken in the trawl, 324 were captured in one tow at station T-15 in December 1973. They appeared at 16 of 18 seine stations and 3 of 21 trawl stations. The c/h was 5.9 for the 25 ft seine, 3.8 for the 80 ft seine, 27.2 for the 150 ft seine, and 0.8 for the trawl. Mummichogs were captured year round seining and in July and December trawl- ing. Most (48%) were taken in spring (April, May, June) followed by fall, summer, and winter. Recorded water quality ranges for this species are: salinity, 3.95 to 30.32 �/oo; water temperature, 3.0 to 33.0�C; and dissolved oxygen, 2.36 to 13.20 mg 02/1. Although no mummichogs were positively identified, Fundulus sp. were found in 10% of the mummichog and 3.5% of the white perch stomachs. Some other species known to feed on mummichogs are bluefish, striped bass, summer flounder, and weakfish. Mummichogs are omniverous. Festa (1975) found other Fundulus species, am- phipods, decapods, nematodes, and plant remains in mummichog stomachs. Tidewater Silverside Fifth in abundance was the tidewater silverside, 2,215 specimens constitu- ting 6% of the catch. Seining accounted for 88% of the catch and trawling 12%. They were collected at 13 of 18 seine and 5 of 21 trawl stations. The c/h was 4.3 specimens for the 25 ft seine, 7.2 for the 80 ft seine, 21.8 for the 150 ft seine, and 0.6 for the trawl. They were taken in all months except March by seine and in February, March, July, November, and December by trawl. Of the total catch, 65% were taken in the fall, followed by summer, winter, and spring. Water quality parameters re- corded when tidewater silverside were taken were: salinity, 1.00 to 25.95 �/oo; water temperature, 1.0 to 33.0�C; and dissolved oxygen, 0.00 to 12.50 mg 02/1. No tidewater silversides were positively identified in the fish stomachs studied, however, Menidia sp. were found in bluefish and northern sennet. Striped bass, summer flounder, and weakfish also feed on these silversides. 7.10 Stomach of this species contained: fish remains, Gammaridean remains, copepods, Cladocerans, Cumaceans, Acarians, Turbellarians, insect remains, diatoms, and other unidentified algae. Spot Spot were sixth in abundance; 1,760 specimens making up 5% of the catch. Captured spot ranged from 3 to 18 cm. The larger ones were in their second summer. Length frequencies for 620 spot are given in Tables 81 and 82. Most were taken trawling (64%), 32% were taken seining, and 4% by gill nets. They appeared at 13 of 18 seine stations, 19 of 21 trawl stations, and 7 of 8 gill net stations. The c/h was 0.1 for the 25 ft seine, 14.6 for the 150 ft seine and 2.5 for the trawl. They were captured June through October, 90% being captured in the summer, followed by fall (8%) and spring (2%). Recorded water quality ranges at the time of capture were: salinity, 4.69 to 29.88 �/oo; water temperature 12.2 to 29.0�C; and dissolved oxygen, 0.65 to 10.34 mg 02/1. Spot were found in bluefish and oyster toadfish stomachs. Spot feed primarily on amphipods, especially AmpeZisca sp. and other Gam- marideans; polychaetes, copepods (harpacticoids and calanoids), and mysids (Neomysis cmerzicna). Atlantic Menhaden Atlantic menhaden ranked seventh, 798 specimens constituting 2% of the catch. Most of these were juveniles, ranging from 3 to 15 cm. See Table 83 for length frequency. Of the total, 22% were captured by seining, 39% trawling, and 39% in the gill net. They appeared at 7 of 18 seine stations, 6 of 21 trawl stations, and 6 of 8 gill net stations. The c/h was 0.5 for the 25 ft seine, 2.3 for the 150 ft seine, and 0.7 for the trawl. They were taken in all months of the year. Nine specimens (1%) were taken in winter, one in January, one in February, and seven in March. Of the total, 48% were taken in spring, 42% in summer, and 9% in fall. Recorded water quality ranges for this species were: salinity, 1.87 to 27.85 �/oo; water temperature, 4.0 to 29.0�C; and dissolved oxygen 0.00 to 12.70 mg 02/1. Atlantic menhaden were found in bluefish stomachs. They are also eaten by striped bass and weakfish. All menhaden stomachs analyzed contained diatoms and other algal species; 20% contained calanoid copepods. Banded Killifish The banded killifish was eighth in abundance. The 545 specimens made up 2% of the catch. All except one specimen were taken by seine. They appeared at 9 of 18 seine stations and one trawl station. The c/h was 2.7 for the 25 ft seine. 7.11 They appeared 11 out of 12 months, none being taken in December; 60% were cap- tured during the summer; 35% in the fall, 2% in the winter, and 1% in the spring. Water quality parameters at time of capture ranged from: salinity, 1.00 to 27.90 �/oo; water temperature, 2.0 to 29.OOC; and dissolved oxygen 0.78 to 12.74 mg 02/1. Fundulus spp. were found in mummichogs and white perch stomachs. Banded killifish stomachs contained: polychaete remains, Gammaridean amphi- pods, isopods, Cumaceans, nematodes, and diatoms. Silver Perch Silver perch ranked ninth, the 492 specimens constituting 1% of the catch. Those measured were primarily young of the year. See Tables 84 and 85 for length frequency. Of the total, 66% were collected by seining and 33% by trawling; four specimens were caught by gill net. They appeared at 6 of 18 seine stations, 12 of 21 trawl stations, and 2 of 8 gill net stations. The c/h for the 25 ft seine was 0.2, for the 80 ft seine 0.4, for the 150 ft seine 8.4, and for the trawl 0.4. They were taken July through November; 85% were captured in the summer and 14% in the fall.

Silver perch were found in summer flounder stomachs. They fed on unidentified fish, gastropods (Bittium sp.), decapods (Crangon septemspinosa), and mysids (Neomysis americana). Winter Flounder Winter flounder were 10th in abundance, the 342 specimens constituting 1% of the total catch; 15% were taken by seining and 85% by trawling. They were captured at 9 of 18 seine stations and 20 of 21 trawl stations. None were taken at T-26 in Thompson's Creek. The c/h was less than 0.1 for the 25 ft and 80 ft seines, 0.9 for the 150 ft seine, and 0.7 for the trawl. Winter flounder were found year-round in the study area. Of the total, 43% were collected in the summer, 22% in the fall, and 17% each in winter and spring. Recorded water quality ranges at the time of sampling were: salinity, 1.25 to 31.80 �/oo; water temperature, -1.0 to 28.50C; and dissolved oxygen 3.94 to 12.56 mg 02/1. Winter flounder stomachs contained: naked gobies; many species of annelids and nematodes; amphipods, decapods, Cumaceans, mysids and Brachyuran crabs; and many mollusks. Bivalve siphons, primarily Mercenaria mercenaria, were found in 28% of all winter flounder stomachs. Length frequency data for the winter flounder is listed in Tables 86 and 87. 7.12 White Perch White perch ranked 12th in abundance, the 293 specimens composing 1% of the total catch. They were taken by all three gear types: seine (9%), trawl (66%), and gill net (25%). They were captured at 4 of 18 seine stations, 6 of 21 trawl stations, and 3 of 8 gill net stations. The c/h was 0.1 for the 25 ft seine and 0.4 for the trawl. Perch were taken year-round trawling, primarily in the summer by seine and in the winter by gill net. Overall 41% were taken in the winter, 10% in the spring, 17% in the summer, and 32% in the fall. Water quality parameters at which perch were taken were: salinity, 1.00 to 30.86 �/oo; water temperature 0.5 to 29.0�C; and dissolved oxygen 0.00 to 10.72 mg O2/1. While some fish and fish eggs were found in white perch stomachs, inverte- brates made up most of their diet. Annelids, primarily polychaete remains, were found in 28% of the stomachs examined. Crustaceans were the most abundant food item. In descending order of occurrence those identified were: mysids - (Neomysis americana); decapods - (Crangon septemspinosa); amphipods - (Gammarus fasciatus and Leptocheirus plumulosus); and calanoid copepods. Bluefish Bluefish ranked 17th with 153 specimens. They were taken by all three types of gear; seine (38%), trawl (11%), and gill net (51%). Bluefish were captured at 11 of 18 seine stations, 8 of 21 trawl stations, and 7 of 8 gill net stations. The c/h was less than 0.1 for the 25 ft seine and the trawl and 1.1 for the 150 ft seine. Of the 128 specimens measured, 124 were probably young of the year. See Table 88 for length frequency. They appeared June through October, 89% of these July through September with 50% in August. Recorded water quality ranges at the time of capture were: salinity, 1.00 to 29.88 �/oo; water temperature, 2.5 to 28.5�C; and dissolved oxygen 0.00 to 10.72 mg 02/1. Fish remains were found in 54% of the bluefish stomachs examined. Those species identified are: bay anchovy, Atlantic menhaden, silverside species, and spot. Invertebrates found include Nereis spp., Crangon septemspinosa, Palaemonetes vulgaris, Neomysis americana, and Brachyuran crab larva. Weakfish Nineteenth in abundance was the weakfish with 139 specimens. They were most abundant in trawl samples with 133 specimens (96%) taken. Three weakfish were taken by seine and three in the gill net. They were taken at 3 of 18 seine, 17 of 21 trawl, and 1 of 8 gill net stations. The c/h was 0.31 for the trawl. They were present August through October, with most specimens (94) being taken in August. Water quality parameters at the times when weakfish were taken were: salinity, 13.82 to 29.05 �/oo; water temperature, 14.01 to 27.0�C; and dissolved oxygen, 1.44 to 9.26 mg 02/1. Fish remains were found in 50% of the weakfish stomachs examined; the only identifiable species was the bay anchovy. The three most important forage in- vertebrates in decreasing order are: Neomysis americana, Crangon septemspinosa, and AmpeZisca spp. Others are CaZlinectes sapidus and Xanthidean crab remains. 7.13 Length frequency data for weakfish is listed in Tables 89 and 90. SUMMARY The fish population of the Manahawkin Bay - Little Egg Harbor system was sampled July 1973 through May 1975. The following gear was utilized: a 25 ft x 5 ft bag seine, an 80 ft x 6 ft bag seine, a 150 ft x 10 ft bag seine, a 16 ft bottom trawl, and a 125 ft x 6 ft experimental gill net. The 18 seine stations were sampled at various times. Seven of these were located in the bay, five in creeks, five in lagoons, and one in a tidal pool on the salt marsh. A total of 278 seine hauls were made; 48 species of finfish numbering 25,662+ specimens were taken. The c/h for the 25 ft seine was 33.4 specimens, for the 80 ft seine 77.5, and for the 150 ft seine 447.9. The 10 most abundant species numbered 24,118 specimens and made up 97% of the seine catch. There were 21 trawl stations sampled; 12 were bay stations, 7 were creek stations, and 2 were lagoon stations. Fifty-four species of finfish totaling 9,730 specimens were collected in 427 trawl hauls. The c/h was 22.6 specimens. The 10 most abundant species totaled 8,765 specimens and constituted 90% of the trawl catch. Eight gill net stations were located in the bay, one in Dinner Point Creek, and four in lagoons; 21 species of finfish numbering 614 specimens were captured. Two of these, the smooth dogfish and the striped bass were taken only by gill net. The five most abundant species numbered 554 specimens and made up 90% of the catch. Altogether, 66 species of finfish totaling 35,989+ specimens were taken. The five most abundant species were: bay anchovy, Atlantic silverside, fourspine stickleback, mummichog, and tidewater silverside. These five made up 80% of the total catch.

Makai ABSTRACT The purpose of this portion of the study was to map and/or describe the physical and chemical attributes of the Manahawkin Bay - Little Egg Harbor system. Thirty-four water quality stations were selected and scheduled accordingly to be sampled bimonthly, monthly, and/or seasonally from July 1973 until February 1974 and from June 1974 until May 1975. The following parameters were measured: temperature, tidal stage, water depth, dissolved oxygen, salinity, pH, carbon dioxide, transparency, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, detergent, B.O.D., orthophosphate, and total and fecal coliforms. During the two survey periods, water temperatures ranged from -2.7 to 30.5� C. Dissolved oxygen ranged from 0.0 to 17.1 mg O2/1. The pH ranged from 5.7 to 10.0. Salinity ranged from 0.3 to 32.0 �/oo. Carbon dioxide ranged from 0.0 to 36.3 mg C02/1. Secchi disc depth measurements ranged from 3 inches (in) to 11 feet (ft). B.O.D. levels ranged from 0.0 to >12.2 mg 02/1. Nitrite nitrogen ranged from 0.0 to 0.036 mg NO2-N/1 and nitrate nitrogen ranged from 0.0 to 3.98 mg NO3- N/1. Ammonia levels ranged from 0.0 to 0.4 mg NH3-N/1. Orthophosphate ranged from 0.0 to 0.17 mg PO4-P/1. Detergent concentrations ranged from 0.0 to 0.34 mg/l. Bacterial analysis showed coliform counts ranging from <3 to 4,600 most probable number per 100 ml (MPN/100 ml), and fecal coliform counts from <3 to 2,400 MPN/ 100 ml. Slight traces of DDT and its metabolites were detected in 84.6% of the fish, with values ranging up to 17.0 ppb. Only 20% of the shellfish meat showed any traces. Of the sediment samples, 76.6% did show traces of DDT and its metabolites with concentrations ranging up to 69 ppb. The other insecticide observed was hep- tachlor epoxide, detected in 33.3% of the samples. Heavy metal analysis of fish, shellfish, and sediment samples showed that cadmium, chromium, lead, zinc, and mercury were present. In the fish samples, only slight traces of cadmium and chromium (<0.01 ppm) were detected. Lead ranged from 0.0 to 6.1 ppm, zinc from 5.65 to 16.85 ppm, and mercury from 0.0 to 0.4 ppm. In the shellfish meat, only slight traces of chromium (<0.01 ppm) were detected. Cadmium ranged from <0.01 to 0.75 ppm; lead ranged from 0.0 to 5.7 ppm; zinc ranged from 2.5 to 20.0 ppm; and mercury from 0.0 to 0.29 ppm. In the sediment samples, cadmium ranged from 0.0 to 3.0 ppm; chromium from 3.0 to 50.0 ppm; lead from 0.0 to 297.5 ppm; zinc from 2.0 to 66.6 ppm; and mercury from 0.0 to 2.75 ppm.

INTRODUCTION Over the years, New Jersey's coastal areas have become a significant real estate frontier. The tremendous demands by individuals to have homes built near direct access to the water system had brought development to an all-time record. However, suitable construction sites have become exhausted and the trend now would be to dredge-fill wetlands to provide lagoon-type real estate. Lagoons are usu- ally bulkheaded to prevent erosion and allow for boat dockage. The importance of marshland in an estuarine ecosystem has been well docu- mented. De la Cruz (1973) stated that every square meter surface of marsh, re- gardless of geographic location, produces about the same amount of organic mater- ial annually and will supply the same biomass of detritus to the estuarine food chain. Therefore, it is evident that the secondary productivity of coastal waters manifested in the productive fisheries and shellfisheries is dependent on the bio- logical process occurring on the marshes. Gagliano (1974) determined that losses of marsh areas or disturbances of the marsh in ways which limit food production will cause reduction of stocks dependent on those food resources. The direct loss of good habitat with the rise of arti- ficial areas (lagoons) has made it necessary to evaluate such an area as to what role this would now play in the food web. The objective of this study is to evaluate the importance of the Manahawkin Bay - Little Egg Harbor system by determining population utilizations and condi- tions. Special emphasis will be placed on comparing an artificial area to a natural area. Such information could be used to help maintain coastal waters at a level which would allow their continued use as spawning, nursery, and harvest areas. MATERIALS AND METHODS The Manahawkin Bay - Little Egg Harbor system study area originally was planned to include all water acreage from Beach Haven Inlet (lower boundary) to Barnegat Inlet (upper boundary). Since the studies of the upper Barnegat system (Makai 1973) had ended at Barnegat Inlet, the new survey should have continued from there. However, in December (during the first survey period), it was decided to reduce the study area and designate Sandy Island as the upper boundary. Field sampling was conducted during July 1973 to February 1974, and from June 1974 to May 1975. During these two survey periods, 34 water quality stations were selected and scheduled accordingly to be sampled bimonthly, monthly, and/or seasonally. A special emphasis was placed in comparing a habitat that has already been developed (artificial) to a natural area. This artificial system will be defined as wetland and uplands that have, after dredge-fill operations, been created into lagoon-type real estate development. Dinner Point Creek and the drainages from Meyers Pond and Oyster Point were chosen as the "natural" area. It was felt that close proximity of the two systems would allow for a good comparison of habitat. 7.16 Location of all stations can be seen in Figures 3, 4, and 5 (all figures for this report in Appendix A). Due to the shallowness of this system, most bay sta- tions were located in the channel of the Intracoastal Waterway. This allowed for both surface and bottom sampling. Sixteen chemical and physical parameters measured were divided as follows. Hydro Run Surveys Bimonthly sampling of surface and bottom waters were conducted at 31 sta- tions during maximum flood and ebbing tides. The survey area was divided into three sampling frequencies: (1) the entire bay region (9 stations) and the mouths of Dinner Point Creek, Mill Creek, and Beach Haven West Complex; (2) Dinner Point (4 stations) and Mill Creek (7 stations); and (3) Beach Haven West Lagoon Complex (11 stations). During this survey, the following parameters were mea- sured: temperature, tidal stage, water depth, dissolved oxygen, pH, salinity, carbon dioxide, and Secchi disc depths. Most of the 31 stations corresponded to the seining, trawling, and gill netting stations selected in the fish study. The above water quality data were also collected during all field work of the fish survey. Nutrient Collections Surface water samples were collected monthly at 21 of the 34 stations during a falling tide. Two 1,000 ml polyethylene bottles were filled at each station. During the first survey period (July 1973 - February 1974), one bottle was fixed with 40 mg of mercuric chloride. Continuously high nitrate nitrogen results forced a change in fixing agents (I ml of 'H2SO4). Both bottles were stored in a cooler packed with ice during field collections. All samples were stored in a refrigerator or ice chest (depending on availability) and transported early the following morning to the Lebanon Laboratory for iimmediate analysis. Water sam- ples were tested for ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, or- thophosphate, detergent (all usually within 96 hours after collection), and B.0.D. levels. Bacterial Monitoring Program Seasonal sampling was conducted at 27 of the 34 water quality stations. Collections were taken 18 in below the surface, in sterilized 6 oz. glass bot- tles, during a flood tide. Within I hour of completing the survey, samples were taken to the Bureau of Shellfish Control at Leeds Point for evaluation. Tributary Survey Five major tidal creeks situated within the study area were also chosen to be seasonally sampled during both a flood and ebb tide. Such systems were Tuc- kerton Creek, Thompson Creek, Parker Run, Westecunk (West) Creek, and Cedar Run. The parameters measured were temperature, water depth, tidal stage, salinity, pH, dissolved oxygen, Secchi disc depth, and carbon dioxide. Twenty-four Hour Tidal Survey A 24 hour monitoring program was conducted seasonally in Dinner Point Creek and Beach Haven West (System A - mouth of Lagoon 08). Parameters measured hourly 7.17 were as follows: tidal stage, temperature, oxygen concentrations, salinity, and Secchi disc depths (as daylight permitted). Gill netting and plankton sampling were also included during this survey. Pesticide and Heavy Metal Survey Selected fish, shellfish, and sediment samples were analyzed for both pesti- cides (chlorinated hydrocarbons) and heavy metal (mercury, cadmium, lead, chor- mium, and zinc) concentrations. Species of fish chosen were: oyster toadfish, winter and summer flounder, white perch, menhaden, and spot. Shellfish collected were the ribbed mussels and hard clam. Composite samples (20 g) of each species were placed in plastic (polyethylene) bags and kept frozen until time of analysis. Sediment samples were collected periodically through the summer months (1974- 1975 period) with a 6 in Eckman bottom dredge. All samples were placed in plastic pint containers while in the field. Within 24 hours after collection, excess water was decanted from the sample. The remainder (mud) was placed in a drying oven at 700C (158 OF). The dry residue was then pulverized and stored in 6 oz. wide mouth glass jars until analyzed. Isohaline and Isotherm Distribution Study Two simultaneous transects, initiating in Beach Haven Inlet and running north to Sandy Island, were conducted during two flood and ebbing tides. Surface water temperatures and salinity levels were measured during June and July at selected stations within the bay. Water temperatures were recorded with a FT3 Marine Hydrographic Thermometer and salinity levels were measured by titration with AgNO3 (silver nitrate) for chlorinity and converted using Knudsen tables. Laboratory Equipment Most of the equipment and procedures used in testing water samples have been described in Makai (1971, 1973). However, there were some changes which shall be noted here. All of the following analytical procedures are according to Standard Methods (American Public Health Association 1971). Ammonia Distillation Method Nitrite Nitrogen - Naphthylamine - Sulfanilic Acid Method Nitrate Nitrogen - Ultraviolet Spectrophotometric Method Orthophosphate - Stannous Chloride Method Detergents - Methylene Blue Method (ABS) B.O.D. (Biochemical Oxygen Demand) 5 day test Total and fecal coliform counts - tests determined by New Jersey Bureau of Shellfish Control 7.18 Nitrate nitrogen levels were detected on a Beckman DB-4V (visible spectro- photometer). All other colorimetric tests were run with a Bausch and Lomb Colorimeter Spectronic 20. All pesticide samples (chlorinated hydrocarbons) were analyzed by the New Jersey Health Department with a Microtek 220 Electron Capture Gas Chromatograph equipped with a tritium detector. Samples were injected on three different columns (OU-17, SE-30, and OU-210) in order to verify and confirm the presence of pesticides in the sample. The method used to extract the pesticides in the sample is the official procedure found in the Methods of Analysis of the Associa- tion Official Analytical Chemist (Assoc. Official Anal. Chem. 1975). All heavy metal levels (Pb, Cd, Cr, and Zn) except mercury, were measured on a Perkin Elmer Model 303 Atomic Absorption Spectrophotometer according to methods listed in Standard Methods (13th edition). Mercury levels were detected with a Perkin Elmer Model 303 Atomic Absorption Spectrophotometer according to methods listed in A.O.A.C. (1973, Vol. 56, No. 2). Transparency - Secchi disc (30 cm) Seven Model D Waterproof Ryan Thermographs were used to record year-round water temperature data. This instrument has a recording span of 45 days and two centigrade ranges: -5� to +250 and +100 to 400C. In order to change temper- ature ranges, the recorder had to be sent back to the company for calibration. All recorders were housed in a protective pipe assembly (Makai 1971). Only six recorder stations were selected and the seventh instrument was used as a spare. Location and depth were as follows: Beach Haven Inlet - Flashing Light, Red no. 92 (15 ft); Little Egg Harbor - Long Point (14 ft); Manahawkin Bay - Flashing Light no. 6 (6 ft); Lower Barnegat - Flashing Light no. 73 (7 ft); Beach Haven West - System A, Lagoon no. 08 (7 ft); and Dinner Point Creek (3 ft). Tidal data was obtained from the Coast and Geodetic Survey Tide Tables At- lantic Coast of North America (U.S. Department of Commerce 1973, 1974, 1975). Coast and Geodetic Survey Charts with a scale of 1:24,000 and Nautical Chart 824-SC (1:40,000) were used for all bay and tributary morphometric measurements. Linear measurements were obtained with the use of a map rotometer. All area measurements were computed with a Keuffel and Esser Compensating Polar Planimeter. Profiles were mapped with a Bendix Fathometer. Description of Area The Manahawkin Bay - Little Egg Harbor watershed study area consisted of all water acreage of the Little Egg Harbor Bay, Manahawkin Bay, drainages of Dinner Point, Meyers Pond, Popular Point, Mill Creek, Beach Haven West Lagoon Complex, and other tributaries such as Tuckerton Creek, Thompson Creek, Parker Run, Weste- cunk Creek, and Cedar Run. This was a total of 26,247 acres surveyed; Little Egg Harbor - Manahawkin Bay comprising 97.4% of the total. This estuarine system is located in the southern portion of Ocean County and is separated from the Atlantic Ocean by the land barrier Long Beach Island. The only access to the ocean from this area would be either through Beach Haven Inlet or Barnegat Inlet via Oyster Creek Channel and/or Double Creek Channel. 7.19 Islands and flats near Barnegat Inlet restrict the amount of tidal water entering or leaving the bay. Currents within this inlet are found to be rapid (4.2 ft/sec). It was reported by Ichthyological Associates (1972) that the tidal flow enters the inlet and splits into a northward flow to Bayhead and a southward flow to the Manahawkin Causeway. Beach Haven Inlet allows more tidal exchange as compared to Barnegat Inlet. Storm conditions are constantly altering the channel configuration in the inlet and eventually effect the flow pattern. Such changes greatly determine the shape of the southern tip of Long Beach Island. According to Charlesworth (1968), the flood current pattern in the Intra- coastal Waterway channel behind the barrier island is the major entering channel, as well as issuing channel, and Marshelder Channel is of intermediate importance. Some minor flow also passes through the numerous islands via Barrel, Middle,and Hither channels. Charlesworth also reported that the ebb current pattern in south Little Egg Harbor is interpreted to be that of a tidal drain, with the greatest centripetal drainage into the Intracoastal Waterway section behind the barrier island between Beach Haven and Holgate. Flow through Marshelder Channel from the southwest por- tion of Little Egg Harbor would be the next major drainage area. Table 91 lists maximum observed current velocities in the vicinity of Beach Haven Inlet (Table 91 through 171 which are associated with this report, are located in Appendix B.) The tidal flow through Manahawkin Bay and Little Egg Harbor is in a north- south direction. The tide is of the semidiurnal type; there are two flood and two ebb tides in a normal day. Tidal influence extends to the Manahawkin Causeway. The high water difference is 3 hours and 17 minutes from Little Egg - Beach Haven Inlet. The tidal range is 1.5 - 2.6 ft. North of the Manahawkin Causeway, the tidal range is smaller, 0.8 - 1.5 ft. The bay system is very shallow. At mean low water, the bay depth ranges from 0.5 to 34 ft. From the 25,563 water acres, 88% are 6 ft or less in depth. Access through the 18 mile (statute) study area is provided by the Intracoastal Waterway which extends from Beach Haven Inlet northward along the eastern portion of the bay as far as channel light Flashing Red "34" (Brant Beach area). From here, it runs northwest to the Manahawkin Causeway and changes again to a northeastern direction, which eventually leads to the lower Barnegat Bay region. A smaller channel running, parallel with the shore line, allows access to the western por- tion of the bay (Long Point northward to Manahawkin Causeway). The land barrier Long Beach Island is approximately 21 miles long. The eastern bay shore is heavily developed; however, there are portions of this island that still contain undisturbed beaches, dunes, and marshes. The only access to Long Beach Island is by the Manahawkin Causeway. A great deal of the western bay shore still remains natural marsh. It is estimated that a total of 15,922 acres of wetlands are located within the study area. Portions of this total acreage are part of the Great Bay Boulevard Wildlife Management Area (3,789 acres) and Manahawkin Wildlife Management Area (965 acres); both are managed by the Division of Fish, Game, and Shellfisheries. Also included are Federally owned and/or managed property such as the wetlands extending south of Mill Creek (3,800 acres) and the Gunning River Refuge (3,506 acres) which is adjacent to the Manahawkin tract. 7.20 VEGETATION -- According to the Wetlands Inventory conducted by the New Jersey Department of Environmental Protection, 12 plant species have been identified on wetland maps for the study area: Spartina alternifZora (tall and short salt marsh cordgrass); Spartina patens (saltmeadow cordgrass), Iva frutescens (hightide bush), Baccharis halimifolia (sea myrtle), Distichlis spicata (spike grass), Juncus gerardi (block grass), Panicum virgatum (switch grass), Scirpus olneyi (olvey's bulrush), Phragmites australis (common reed), Typha spp. (cattail), and Spartina cynosuroides (salt reed grass). MARINE PLANTS -- There is very little information on the benthic flora for the Manahawkin Bay - Little Egg Harbor system. Studies have been conducted on marine al- gae for the Barnegat Bay system. Both Moeller (1964) and Loveland et al. (1971, 1972) have identified and listed marine algae for that system. Loveland (1969) reported that most algae in Barnegat Bay appear to be unattached and great masses of the dominant species drift with the currents along the bottom. From the total of 119 benthic algae species he identified, only 16 occurred over 50% of the time. The more dominant species included Ceramium fastigiatum, Gracilaria verrucosa, Ulva lactuca, Agardhiella temera, and Codium fragile. It has been reported by the New Jersey Department of Environmental Protection during a bay scallop population study that beds of eel grass, Zostera marina, extend from Marshelder Island along the eastern portion of the bay northward into Barnegat Bay. During ecological studies conducted in the Little Egg Harbor area by Ichthyological Associates (1973), it was reported the area off Beach Haven Heights had sparsely rooted Zostera marina and Fucus sp. Floating mats of Ulva lactuca (sea lettuce) were found to be very abundant. It was also reported both rooted (extensive beds) and floating Zostera were present in the water area off 14th Street, Ship Bottom. Entermorpha and Ulva were also present. McCurdy (1971) reported,while collecting sediment samples, finding both Zostera and Codmium in the waters near Surf City. Gracilaria was also identified in the Tuckerton Cove area. Ichthyological Associates also reported Zostera beds near Cedar Run. Fucus was found along the banks, and Ulva was observed floating throughout the area. Near the mouth of Parker Run, beds of Zostera were also present. Fucus was re- ported to be attached to the banks, and Agardhiella sp. and Ulva floating through- out the area. In Beach Haven Inlet, floating Fucus, Zostera, and Ulva (not rooted) were reported. Sisson (1968) reports that Codium fragile (Japanese oyster weed) will attach itself to any hard substrate including live oysters, oyster shells, mussels, sea scallop, and bay scallops. It has caused mortality to the oyster and scallop pop- ulation in Rhode Island waters. So far, it has become a nuisance on the clam beds of Barnegat Bay and Little Egg Harbor. The presence of Zostera and Ruppia within an estuary is important because they are primary producers that provide food for aquatic organisms (Odum 1961). MARSHLAND DEVELOPMENT -- Since the implementation of the Wetlands Act of 1970, New Jersey has sought to control the permanent alterations or loss of remaining coastal wetlands. Ferrigno (1973) reported that during the past 20 years, 23.5% of the 263,000 acres of tidal marsh in New Jersey have been lost to development. There are several forms of alteration; usually the most obvious is dredging and filling activities. The main purposes for dredge and fill operations are to provide: (1) land for housing development and access to coastal bays and 7.21 rivers; (2) land for industrial development and access for transportation; and (3) navigational channels. In a study conducted by Nieswand et al. (1972), it was reported that over 90% of the total lagoon developments along the New Jersey shore are located with- in Ocean County. Ferrigno (1972) reported from a total of 37,007 acres surveyed, 26,078 acres or 70.5% of the tidal marsh are still remaining. Within the study area, there are 15,922 acres of tidal marshland (including all State and Federally owned land). This southern portion has had little devel- opment as compared to the remainder of the county (Makai 1973). Ferrigno (1974) reported that 2,139 acres of riparian land extending from Marshelder Channel to the Manahawkin Causeway (Route 72) had been filled. This development has been restricted primarily to the M4anahawkin and Tuckerton areas. In this type of situa- tion, development is referred to as "lagoon type-single family summer dwelling". It is interesting to note that within the Manahawkin area, Beach Haven West Lagoon Complex (Stafford Township) comprises 1,038.3 acres or 49% of the 2,139 acres of wetlands reported to have been filled. In 1972, it was reported this area provided development for a total of 3,625 lots and 1,989 homes. Presently, at least 3,000 homes have been constructed. Of the 62 lagoon systems (Ocean County) identified by Nieswand et al., 16 were situated within the study area. This would account for a total of 2,061.6 acres of lagoon systems. This would be 25% of the total lagoon development acre- age that has taken place within this county. This was estimated to be 48,000 ft of developed shoreline. The total length of these lagoons was 221,950 ft and having the capacity for 7,106 homes. At present, there must be nearly 4,000 built. The Nieswand et al. study also points out that Stafford and Little Egg Har- bor Townships contain a relatively larger amount of lagoon development; Tuckerton and Long Beach contain a significant amount of lagoon development; while Union, Harvey Cedars, Ship Bottom, and Beach Haven contain relatively little lagoon de- velopment. The only municipalities having shoreline but no lagoon development in this area were Surf City and Eagleswood. SEWAGE TREATMENT PLANTS -- Lagoon-type developments provide not only access to coastal areas, but also accommodate a great number of people in relatively small areas. A great majority of these homes were originally constructed for recrea- tional usage or summer housing. Previously, treatment plants usually could handle year-round loads; however, more of these summer homes are now being converted in- to permanent dwellings. The ever-increasing number of people living in the area during the summer as well as year-round has produced overloads that septic sys- tems and existing treatment plants cannot handle. This has generated great con- cern about the water quality conditions within our tidal bays and tributaries. Such conditions may threaten the propagation and harvesting of shellfish within these waters. A very good example of this kind of problem is found in the tidal waters of Raritan Bay. The water quality of our coastal waters are now protected by the New Jersey Department of Environmental Protection and the U.S. Environmental Protection Agency. In the past, most coastal homes were serviced by septic systems. State regulations covering the installation of wastewater facilities in critical areas, dated January 15, 1972, prohibit septic tank construction in New Jersey below 7.22 elevation 10.0 (feet) U.S.C. and G.S. a-ad in other critical areas which are de- fined as those that at one time were below elevation 10.0 and have since been filled above elevation 10.0. Some of the effects of Federal and State requirements in Ocean County are reported by Fellows, Reed, and Weber (1973a, b): (1) several areas in the county have been condemned for shellfishing; (2) coastline communities which have in the past stored sludge during the summer for discharge to the ocean during the winter months have been placed under court order to stop this practice; and (3) the adoption of new stringent water quality standards by the State and the U.S.E.P.A. have pre- cluded construction of even tertiary treatment plants which would discharge into the streams of the county. Ocean County is now in the process of updating existing treatment facilities, providing sewer lines, and proposing that all regional processing facilities (secondary treatment) have ocean discharge. Ocean outfalls have been proposed for the northern (via Mantoloking Borough), central (via Berkley Township), and southern (via Surf City Borough) areas within the county. The following are also planned: 1) Barnegat Light and Harvey Cedars - A collection system has been proposed for the entire area of both boroughs. 2) Beach Haven - This borough has been reported to be completely serviced with sewer lines. The existing primary treatment plant is servicing both the Borough of Beach Haven and the Holgate section of Long Beach Island and discharging the effluent into the Atlantic Ocean. It is ex- pected that the facility will be abandoned upon completion of the pro- posed regional system. 3) Ship Bottom and Surf City - These boroughs are also completely serviced with sewer lines, and the primary treatment plants which also discharge into the Atlantic Ocean will be abandoned. The Surf City treatment facility also serves the North Beach Section of Long Beach Township. 4) Long Beach Township - This township has been divided into five sections which are: High Bar Harbor, Loveladies, North Beach, Brant Beach, and Holgate. Only the Brant Beach section is completely serviced with sewer- age connections. This treatment facility (primary) which discharges in- to the Atlantic Ocean will be abandoned. The Holgate section is con- nected to the Beach Haven treatment plant and the North Beach section is connected to the Surf City treatment plants. Collection systems have been proposed for the remaining areas and will be linked to the regional system. 5) Union - This township has been reported to be in the process of forming a municipal utilities advisory group to plan the overall wastewater development of this area. Some of the existing developed areas are served by the Indianolo Treatment Plant in Ocean Township (Makai 1973). An interim treatment facility has been approved by the County Sewage Author- ity of Barnegat Village, however this facility will be abandoned upon completion of the regional facilities. 7.23 6) Eagleswood - This township is sparsely populated and there are no plans for construction of a collection system. 7) Stafford - The Township Municipal Utilities Authority is reported to operate a treatment plant which only services the Beach Haven West Lagoon Complex. This facility will also be abandoned. 8) Little Egg Harbor - It is reported that the majority of existing devel- oped areas in the township are serviced either by the Mystic Islands treatment plant (privately owned) or by the Tuckerton Municipal Utilities Authority. At present, the township is proposing a master plan for waste- water management. The Mystic Island Facility will be abandoned upon com- pletion of a regional system and there are plans to include a collection system with the regional facilities. 9) Tuckerton - The Municipal Utilities Authority operates a treatment plant (secondary) which is reported to serve the majority of the developed areas within the borough as well as a small portion of Little Egg Harbor Township. Table 92 lists data collected by Nieswand et al. (1972) on existing treat- ment plants that do provide service for developed areas (lagoon systems) situated with the study area. Table 93, also from this study, lists those particular systems that are now connected to these facilities. Approximately 56% or 9 out of 16 lagoon systems reported, are serviced by treatment facilities. SHELLFISH2 -- On the basis of sewage pollution, this water system is one of the cleanest and most productive estuaries along the New Jersey coast. Of the 34,789 acres between Beach Haven Inlet and Barnegat Inlet, only 2,480 acres are con- demned for the harvest of shellfish. Another 902 acres are seasonally condemned (harvest is permitted from January through April). This leaves a total of 31,407 acres, or 90% of this system, open to shellfishing throughout the year. Commer- cially important shellfish found within the system include the hard clam, Mer- cenaria mercenaria; bay scallop, Argopecten irradians; and blue mussel, Mytilus edulis. The soft clam, Mya arenaria and eastern oysterCrassostrea virginica are also found within this system but are not of commercial importance. Hard Clams, Mercenaria mercenaria -- Hard clams are found in abundance in this estuary and support numerous commercial shellfishermen. This area also provides hard clams for thousands of recreational clammers (see Use Study following this report). Harvest methods include: treading, tonging, and raking. The areas -arcsted by the commercial shellfishermen extend from Cedar Run south to Tuc- kerton Cove, on the western side of the bay. A few commercial men also work in upper Manahawkin Bay. The seasonal water behind Long Beach Island is worked ex- tensively from January until the end of April. When it becomes warmer in the spring, wading becomes popular in the shallow areas of the bay that have high ,,nsities of clams. In 1973, Ocean County produced 809,105 pounds of hard clam meats and in 1974, 92J.530 pounds. Ocean County was responsible for 59.5% of the New Jersey hard 'lam landings in 1975 with a total of 964,785 pounds of meat. The majority of the 2 This section was authored by Tom McCloy, a Fisheries Biologist with the N.J. Division of Fish, Game, and Shellfisheries. 7.24 landings in this county are harvested from within the Manahawkin Bay - Little Egg Harbor system. In the fall of 1972, an excellent set of seed clams was discovered on the flats behind Goosebar Sedge, in Little Egg Harbor. The flats are usually exposed at low water. Consequently, a severe winter could destroy many of the clams if they were not harvested. To alleviate this problem, harvest of the legal size clams (1.5 in) was permitted until November. During this time, most of the seed clams harvested were planted on leased ground in Atlantic and Ocean Counties. The clams originally taken from the Goosebar Sedge most likely contributed to the 1973 and 1974 hard clam landings in both Ocean and Atlantic Counties. In the Manahawkin Bay - Little Egg Harbor system, there are over 1,500 acres of bay bottom leased to shellfishermen for the culture of shellfish. These grounds are used primarily as clam layout lots. Clams are planted on these layout lots and held for future use. The clammer may decide to hold the clams when the market is saturated or until their value increases. Some shellfishermen are experimenting with hatchery reared seed clams. Once the seed reaches a certain size, it is planted on leased lots where they hopefully attain a marketable size. At present, this operation has not been successful. Blue Mussel, Mytilis edulis -- Blue mussel beds are found around the numerous islands in the southeast section of Little Egg Harbor. The most extensive beds are between Beach Haven Inlet and Foxboro Point. It is commonly found in the sides and bottom of channels and on marsh banks with hard substrates. This mol- lusk is a suspension feeder and depends on water currents to carry food particles to it. Bay Scallop, Argopecten irradians -- The bay scallop is another commercially im- portant shellfish in Manahawkin Bay and Little Egg Harbor. They inhabit the extensive eelgrass beds from Marshelder Islands north into Barnegat Bay. Har- vesting of bay scallops is accomplished by the use of dredges. Harvesting is re- stricted to the months from November through March and there is a daily limit. During the 1973-1974 season, the area from Marshelder Island north to Egg Island accounted for 100% of the bay scallop landings in New Jersey with a total of 76,889 pounds of meat. In 1975, bay scallops were not abundant enough to support a commercial fishery. It required 2 hours to catch 1 bushel as compared with the 1973-1974 season when the 10 bushel limit could be caught in 3 to 4 hours. Soft Clams, Mya arenaria and Oysters, Crassostrea virginica -- There is a sparse scattering of soft clams on some of the sand bars throughout the bays. Most of the tidal creeks emptying into the system have remnant populations of oysters. Presently, there are no commerical quantities of soft clams or oysters within this system. Figure 6 shows the distribution pattern of shellfish within the Manahawkin Bay - Little Egg Harbor system according to commercial value prepared by the U.S. Department of the Interior, Fish and Wildlife Service. FINDINGS Morphometric Data Upper and lower boundaries of the Manahawkin Bay - Little Egg Harbor system were established arbitrarily for the purpose of survey and analysis as follows: 7.25 Upper Boundary: Farthest point north of Manahawkin Bay indicated by a line from the mouth of Gunning River across the Intracoastal Waterway to Harvey Cedars (channel flashing light R no. 2). Lower Boundary: Indicated by a line across Beach Haven Inlet from Shooting Thorofare to the southern tip of Long Beach Island. The data compiled included the following measurements and calculations made according to Shuster (1959) and Welch (1948): 1) Maximum length (MXL): 15.9 statute miles; 13.8 nautical miles Length of line connecting the two most extreme parts of the bay and crossing no land other than islands. In this case, a line from the tip of the Shooting Thorofare (Beach Haven Inlet) to Sandy Island (channel light no. 82). 2) Maximum effective length (MXEL): 11.4 statute miles; 9.9 nautical miles Length of straight line connecting the most remote extremeties of the bay along which wind and wave action occur without any kind of land interruption. In this case, it is a line from the cove adjacent to the southern tip of Long Beach Island north to the Manahawkin causeway (U.S. Route 72). 3) Maximum width (MXW): 4.6 statute miles; 4.0 nautical miles Length of a straight line connecting the most remote extremities of the bay and crossing no land other than islands. It is a line approximately at right an- gles to the maximum length axis. It is a line from the mouth of Tuckerton Creek (flashing red light no. 17) to Holgate. 4) Maximum effective width (MXEW): 4.2 statute miles; 3.7 nautical miles Length of straight line connecting the most remote extremities of the width F bay niong which wind and wave action occur without any kind of land inter- ruption. It is a line from the mouth of Thompson Creek to Liberty Thorofare. 5) Mean width (MEW): 2,5 statute miles; 2.2 nautical miles The area of the bay divided by its maximum length. .) Maximum depth (MXD): 34 ft; 10.4 m; 5.7 fathoms 7.26 The maximum depth is known. 7) Mean depth (MED): 3.5 ft; 0.6 fathoms The volume of the bay divided by its surface area. 8) Mean depth - Maximum depth relation (MED/MXD): 0.10 The mean depth divided by the maximum depth. This is expressed as a decimal value and serves as an index figure which indicates in general the character of the approach of basin shape to conical forms. 9) Maximum depth - Surface area relation (MXD/AS): 0.21 The maximum depth divided by the square root of the surface area. It is ex- pressed as a decimal value and is an indication of the relation of depth to hori- zontal extent. 10) Total surface area (AS) 39.9 square miles (statute); 25,563 acres Total surface area of the bay. The Coast and Geodetic Survey Chart was di- vided into 14 sections to enable easier and more accurate handling of the plani- meter. The results for each sector were combined to give the total area. 11) Length of shoreline (LSH): East shoreline: 34.3 statute miles; West shoreline: 41.5 statute miles; Total: 75.8 statute miles. The length of the shoreline enclosing the bay measured in statute miles. 12) Volume (V): 3,861,946,790 ft3 28,889,370,202 gallons Formula: v=l/3 (A1 + A2 + A1A2)h Where A is the area of the upper surface of a contour stratum and A2 is the area of the lower surface of the same stratum, the height of the stratum is shown by h. The volume for each stratum is computed from the formula, the sum of the volumes being the total volume at mean low water (Reid 1961). 13) Hypsographic curve: A curve constructed by plotting depth along the ordinate and area along the abscissa. Such a curve provides not only certain elements in the form of a basin, but it also provides a means whereby areas at any depth level may be determined (Figure 7). 7.27 14) Profiles: These provide a pictorial representation of the basin configuration along a selected line. All the profiles selected were perpendicular to the ship channel and are illustrated in Figure 8. Water Quality Data All physical and chemical data collected from July 1973 through February 1974 and June 1974 through May 1975 are presented in Tables 1 to 171. This would also include all water quality data reported in the Fish Studies section. Beach Haven Inlet The inlet is relatively deep and narrow, permitting tidal water intrusion into the Little Egg Harbor - Manahawkin Bay system. Mud flats divide the area into two main channels (Marshelder Channel and the eastern channel) which paral- lel Long Beach Island. Water depth within these channels at mean low water ranges from 0.5 to 34 ft. Currents within the inlet are swift. Station MB-I was situated in the east channel, approximately 500 yards off the mouth of Big Sheepshead Creek. The water depth ranged from 10 to 18 ft at mean low water with a bottom composition of hard sand. Water temperatures at this station varied from 3.5 to 24.0�C and air tempera- ture from 1.0 to 31.0�C (Table 94). Salinity varied from 27.5 to 32.0 �/oo. The pH readings were all basic (7.6 to 8.65). Dissolved oxygen concentrations ranged from 5.6 to 10.9 mg 02/1. Carbon dioxide values were from 0.0 to 19.8 mg CO2/1. Secchi disc depths ranged from 3.0 in to 10 ft. B.O.D. levels ranged from 0.2 to 3.6 mg 02/1 (Table 95). Only traces of ni- trite nitrogen were observed (<0.005 mg NO2-N/1). Nitrate nitrogen ranged from 0.28 to 0.65 mg NO3-N/1. Ammonia nitrogen levels were slight (0.0 to 0.3 mg NH3-N/l). Orthophosphate levels ranged from 0.0 to 0.09 mg PO4-P/1. Detergent levels ranged from 0.03 to 0.32 mg/l. All total and fecal coliform counts were <30 MPN/100 ml. Little Egg Harbor - Manahawkin Bay The land barrier along the eastern portion of the bay extending from Beach Haven Inlet north to Barnegat Inlet is known as Long Beach Island. A great por- tion of this area is developed (bulkheaded and filled in). On the other hand, the western portion of the bay still retains a great deal of natural shoreline and marshland (portions of which are Federal and State owned). There were 11 water quality stations selected in the bay area; however,2 stations (MB-3 & MB-4) were dropped during the first survey period. See Figure 3 for the location of stations MB-2 to MB-llA. Depths ranged from 0.5 to 25 ft at mean low water with bottom composition varying from hard sand to soft mud, detritus, and submerged vegetation. Water temperature recorded ranged from -1.0 to 29.5�C and air temperatures from -4.0 to 35.0�C (Tables 96 to 106). Salinity varied from 19.8 to 30.8 �/oo. The pH readings were all basic (7.1 to 8.45). Dissolved oxygen levels varied from 5.4 to 13.4 mg 02/1 and percent saturation from 72 to 146%. Carbon dioxide values were from 0.0 to 13.4 mg C02/1. Secchi disc depths ranged from 3.0 in to 9.5 ft. 7.28 B.O.D. levels ranged from 0.0 to 5.8 mg 02/1 (Tables 107 to 113). Only slight traces of nitrite nitrogen were observed (<0.005 mg N02-N/1). Nitrate nitrogen ranged from 0.22 to 0.94 mg N03-N/1. Ammonia nitrogen levels were slight (0.0 to 0.3 mg NH3-N/1). Orthophosphate levels ranged from 0.0 to 0.17 mg P04-P/1. Detergent concentrations ranged from 0.0 to 0.33 mg/l. Total coliform counts ranged from <3 to 750 MPN/100ml and fecal coliform counts from <3 to 230 MPN/100 ml. Dinner Point Creek This water system, along with the drainage from both Meyers Pond and Popular Point, were selected as "natural" areas (all wetlands). Dinner Point Creek, the largest of the three streams, is located approximately 4 miles south of the Mana- hawkin Causeway (Route 72). Meyers Pond and Popular Point are 2 and 1.7 miles south of Route 72, respectively. All three systems are tidally influenced by the upper portion of Little Egg Harbor. There were six stations selected in the "natural" area. Four were located in the main stem of Dinner Point Creek: DPC-1 (mouth), DPC-2 (above the conflu- ence of the second branch), DPC-2A (approximately 950 yards upstream of station DPC-2) and DPC-3 (upper end). Stations MP-O (Meyers Pond) and PP-O (Popular Point) were located at the mouth of their respective drainages (Figure 3). It should be noted that water quality measurements in these two systems included only the fish survey, bacterial, and nutrient collections. Access to these areas were limited to high water. Dinner Point Creek was found to be extremely shallow; water depth ranging from 0.5 to 4 ft at mean low water. Bottom composition was soft mud, detritus, and submerged vegetation. Water temperatures recorded at these stations ranged from -0.5 to 30.0�C and air temperatures from -2.7 to 33.0�C (Tables 114 to 117). Salinity varied from 3.3 to 29.6 O/oo. The pH readings ranged from acid to basic (6.3 to 8.3). Dis- solved oxygen levels varied from 0.0 to 12.3 mg 02/1 and percent saturation from 0.0 to 124%. Carbon dioxide values were 0.0 to 36.3 mg C02/1. Secchi disc depths measured from 6.0 in to 4.5 ft. B.O.D. concentrations ranged from 0.0 to 6.0 mg 02/1 (Tables 118 to 121). Only slight traces of nitrite nitrogen were observed (<0.007 mg N02-N/1). Nitrate nitrogen ranged from 0.04 to 3.98 mg N03-N/1. Ammonia nitrogen levels were slight (0.0 to 0.3 mg NH3-N/1). Orthophosphate ranged from 0.0 to 0.11 mg P04-P/1. De- tergent concentrations were from 0.0 to 0.34 mg/l. Total coliform counts ranged from <3 to 4,600 MPN/10lOOml and fecal coliforms from <3 to 750 MPN/10lOOml. Mill Creek This water system, although part of the artificial area, has been presented separately because it is the receiving waters from both the upland drainage of Manahawkin Lake and the effluent (secondary treatment) of the Stafford Municipal Utilities Authority. The creek has been dredged to provide upstream access to lagoon housing. All lagoons along the upstream south shore are presently undeveloped (no bulk- heading or housing present). All lagoons located along the upstream north area are developed (housing present although bulkheading may or may not be present). 7.29 Seven stations were selected in this water system. Stations MC-0, MC-1, MC- 2, MC-3, and MC-6 were located in the main channel. Stations MC-4 and MC-5 were located at the distal end of an undeveloped and developed lagoon, respectively. See Figure 4 for locations. Bottom composition varied from soft mud to hard sand and detritus. Water depth measured ranged from 3 to 18 feet. Water temperature recorded at these stations ranged from -0.5 to 30.5�C and air temperatures from -4.0 to 33.5�C (Tables 122 to 128). Salinity varied from 0.3 to 27.1 �/oo. The pH values ranged from acid to basic (6.2 to 8.9). Dis- solved oxygen concentrations ranged from 0.0 to 15.0 mg 02/1 and percent satura- tion from 0.0 to 169%. Carbon dioxide values were from 0.0 to 10.3 mg C02/1. Secchi disc depths recorded ranged from 9.0 in to 5.0 ft. B.O.D. levels ranged from 0.0 to >12.2 mg O2/1 (Tables 129 to 132). Slight traces of nitrite nitrogen were observed (<0.004 mg NO2-N/1). Nitrate nitrogen ranged from 0.36 to 0.90 mg N03-N/1. Ammonia nitrogen levels were slight (0.0 to 0.3 mg NH3-N/1). Orthophosphate ranged from 0.0 to 0.06 mg PO4-P/1. Detergent levels measured ranged from 0.03 to <0.2 mg/l. Total coliform counts ranged from 3.6 to 4,600 MPN/100 ml and fecal coliform counts ranged from <3 to 2,400 MPN/100 ml. Beach Haven West Lagoon Complex In order to simplify presenting data, this artificial area was subdivided into the following: System A, B, C, and D (Figures 4 and 5). This complex is tidally influenced from Manahawkin Bay; none of these systems have any fresh water input other than street runoff or housing effluent. Almost all of the lagoons are developed (housing and bulkheads) with the ex- ception of the lower portion of System D (area parallel to Mill Creek). At present, homes are being constructed and the perimeter of this area will eventually be bulk- headed. Eleven stations were selected within these systems and the 11 are as follows: System A - station BHW-7 was situated in the main channel and station BHW-8 was located near the mouth of Lagoon 08; station BHW-1 was situated below the junc- ture of Systems D and B; System B - station BHW-4 was located in the main channel whereas station BHW-5 was situated at the distal end of Lagoon 15; upstream station BHW-6 was midway in Lagoon 24; System D - station BHW-2 was located at the distal end of undeveloped Lagoon 43, whereas station BHW-3 was located in the main chan- nel between Lagoons 62 and 63; System C - station BHW-9 was located at the mouth and station BHW-10 was upstream in the main channel, just below the mouth of Lagoon 31; station BHW-1ll was located at the distal end of Lagoon 37. Water temperature recorded at these stations ranged from 0.4 to 30.OOC and air temperatures from 1.3 to 35.0�C (Tables 133 to 143). Salinity ranged from 13.2 to 28.5 O/oo. The pH readings varied from slightly acid to basic (6.85 to 6 3). Dissolved oxygen levels were from 0.0 to 13.1 mg O2/1 and percent satura- tion from 0.0 to 141%. Carbon dioxide values ranged from 0.0 to 11.2 mg C02/1. Secchi disc depths recorded ranged from 1.5 to 11.0 ft. and water depths measured were from 4 to 26 ft. B.O.D. values recorded ranged from 0.0 to 6.2 mg O2/1 (Tables 144 and 150). Slight traces of nitrite nitrogen were observed (<0.007 mg NO2-N/1). Nitrate nitrogen levels ranged from 0.42 to 2.03 mg NO3-N/1. Ammonia nitrogen values 7.30 were small 0.0 to 0.4 mg NH3-N/l. Orthophosphate ranged from 0.0 to 0.055 mg P04- P/I. Detergent concentration detected ranged from 0.09 to 0.30 mg/I. Total coli- form counts ranged from 11 to 4,600 MPN/i00 ml and fecal coliform from 3.6 to 1,500 MPN/100 ml. Tidal Creek Survey Four out of five tidal creeks selected were sampled during the 2 year study. Thompson Creek could not be worked into the schedule. TUCKERTON CREEK -- This water system is located in the lower western portion of Little Egg Harbor. Saline water entering via Marshelder Channel greatly in- fluences this region. The creek has been extensively developed and receives waters from the upland drainage of Tuckerton Lake and the effluent (secondary) of the Tuckerton Municipal Utilities Authority (Table 92). Seven stations were selected in this tributary. Station TC-0 was situated approximately 500 yards off the mouth of the creek. Stations TC-I (Flashing Light "17"), TC-3 (near clam house), TC-5 (across from Hayes BP gas station), TC-6 (near Gulf Station), and TC-7 (below lake drainage) were located in the main stem and TC-2 (borrow pit) and TC-4 (near Daddy Tucker Drive) were in lagoons (Figure 3). Water temperatures recorded at these stations ranged from 2.0 to 27.0�C and air temperatures ranged from 2.0 to 27.0�C (Table 151). Salinity varied from 1.6 to 29.8 0/oo. The pH readings ranged from slightly acid to basic (6.8 to 9.15). Dissolved oxygen concentrations ranged from 0.0 to 17.1 mg 02/1 and per- cent saturation from 0.0 to 181%. Carbon dioxide ranged from 0.0 to 25.5 mg C02/ 1. Secchi disc depths recorded ranged from 1.0 to 6.5 ft and water depths varied from 3 to 21 ft. PARKER RUN -- This tidal creek is located approximately 3 miles north of Tuckerton Creek. Most of the surrounding area remains in a natural state with the exception of an upstream site (partial upland and wetlands) along the southern shore and an access road leading to a small developed region near the mouth (northern shore). Six stations were selected in this system. Station PR-O was located approxi- mately 200 yards off the mouth of the creek). Stations PR-I (Flashing Light "1") and PR-2 (near cedar stakes) were situated in the main stem. Stations PR-3 (un- developed cove), PR-4 (south branch), and PR-5 (end) were in the channel of the creek extensions (Figure 3). Water temperatures recorded in this system ranged from 3.0 to 24.0�C and air temperatures from 3.0 to 27.OOC (Table 152). Salinity varied from 3.4 to 28.4 �/oo. The pH readings ranged from slightly acid to basic (6.8 to 8.72). Dissolved oxygen levels ranged from 0.0 to 16.9 mg 02/1 and percent saturation from 0.0 to 170. Carbon dioxide values ranged from 0.0 to 12.6 mg C02/1. Secchi disc depths varied from 9.0 in to 7 ft. Water depth recorded ranged from 3 to 20 ft. WESTECUNK (WEST) CREEK -- This tributary situated in Eagleswood Township is lo- cated about I mile north of Long Point (channel light no. 2). The south side of this creek has been extensively developed, however, most of the northern area still remains in natural state. This system receives the waters of all drainage from the town of West Creek as well as from the cranberry bogs further west. 7.31 Eight stations were selected in this system. Station WC-0 was situated ap- proximately 150 yards off the mouth of the creek. Stations WC-1 (Flashing Light "3"), WC-2 (upstream of Flashing Light "6"), WC-3 (across from Texaco), WC-4 (bridge), WC-5 (adjacent to lagoon), WC-6 (above public launching ramp), and WC-7 (below Rt. 9) were all located in the main stream. See Figure 3 for loca- tions. Water temperature recorded at these stations ranged from -0.5 to 28.50C and air temperatures from -1.5 to 34.0�C (Table 153). Salinity varied from 0.4 to 28.6 0/oo. The pH values ranged from acid to basic (6.2 to 8.4). Dissolved oxy- gen concentrations ranged from 1.4 to 13.5 mg 02/1 and percent saturation from 30 to 147%. Carbon dioxide levels ranged from 0.0 to 10.2 mg C02/1. Secchi disc values ranged from 1.5 to 5 ft and the sampled water depths ranged from 3.25 to 10 ft. CEDAR RUN -- This water system is situated between Mill Creek and Dinner Point Creek. Except for some small homes, docks, and an access road constructed along the northern shore, most of the surrounding area remains in a natural state (wet- lands). Six stations were selected in this system. Station CR-O was situated approx- imately 600 yards off the mouth of the creek. Stations CR-1 to CR-5 were located in the main stream (see Figure 3). Water temperatures in this system ranged from 1.0 to 28.30C and air tempera- tures from -1.0 to 29.50C (Table 154). Salinity varied from 1.5 to 28.3 �/oo. The pH values ranged from acid to basic (6.0 to 8.3). Dissolved oxygen concentrations ranged from 3.2 to 11.9 mg 02/1 and percent saturation from 45 to 114%. Carbon dioxide levels ranged from 0.0 to 11.7 mg C02/1. Secchi disc measurements ranged from 1.0 to 4.0 ft and water depths from 1 to 8 ft. Thermograph Data As was previously mentioned, six thermographs were placed in selected areas to record daily water temperatures over a 45 day period (Figure 3). However, during the months of July and August and at some stations in September of the first survey period, data was lost due to time spent sending recorders back to the com- pany for calibration. At the end of this first survey period (July 1973 to Febru- ary 1974), the instruments were not pulled out while preparing an interim report. This allowed a complete recording of 12 months of data. Figure 9 shows monthly mean, standard deviation, and ranges of temperature for each station. This also shows that the recorded water temperatures during the survey periods ranged from -2.7 to 29.40C. It should also be noted that water temperatures at Long Point, Manahawkin Bridge, and Lower Barnegat Bay during the month of August 1973 exceeded the range on the tape (>250C). This was due, as explained above, to a shortage of available instruments calibrated for the high range (+20 to +400C) and the situation was not corrected until September. Pesticide - Heavy Metal Analysis Monthly fish collections showed it was very difficult to collect the same species consistently at selected stations. Even more so to collect a sufficient quantity of any species at a particular station. This was especially evident during 7.32 the winter and some of the spring collections. Both sampling stations and fish species were selected according to their availability within specific areas. Oyster toadfish (Opsanus tau), winter flounder (Pseudopleuronectes americanus), summer flounder (Paralichthys dentatus), Atlantic menhaden (Brevoortia tyrannus), white perch (Morone americana), and spot (Leiostomus xanthurus) were the selected species in all chlorinated hydrocarbons and heavy metal testing. The oyster toadfish and white perch made up 57% of the samples. Hard clam, Mercenaria mercenaria, and the Atlantic ribbed mussel, Modiolus demissus, were the two shellfish species selected for the pesticide and heavy metal analysis. As was previously mentioned in the shellfish section, the hard clam is the more abundant and is consistently found throughout the bay system. The ribbed mussel, on the other hand, is not commercially important but can be found along the sedge banks (intertidal) of most of the tributaries. A total of 54 samples were sent to the State of New Jersey Fisheries Laboratory, Lebanon for analysis. Samples were analyzed for the chlorinated hydrocarbons L-BHC, lindane, aldrin, heptachlor, heptachlor epoxide, dieldrin, and DDT and its metabolites. Heavy metal analysis included cadmium, chromium, lead, zinc, and mercury. Results of residue analysis for the chlorinated hydrocarbons found in fish, sediment, and shellfish are listed in Tables 155 to 159. The data from these analyses are reported in microgram per kilogram (ppb). Results of heavy metal concentrations detected in fish, sediment, and shellfish are listed in Tables 160 to 162. All data are reported in milligram per kilogram (ppm). Slight traces of DDT and its metabolites were detected in 34.6% of the fish samples with values ranging up to 17 ppb. Only 20% of the shellfish samples showed any traces. None of the other insecticides were detected in either the shellfish or fish meat. The chlorinated hydrocarbons insecticides, generally speaking, are the most toxic to aquatic life. They are known to be very stable compounds and found to be very difficult to control once released into the environment. Some of the organochlorine pesticides, including some of their metabolites, are directly toxic at concentrations of less than 1 mg/I. DDT and its metabolites were detected in 76.6% of the sediment samples. Concentrations ranged up to 69 ppb. The only other insecticide observed was heptachlor epoxide; detected in 33.3% of the samples. Results for Little Egg Harbor Bay and Manahawkin Bay showed that only one sediment sample collected north of the Manahawkin Causeway (Route 72) had any detectable traces of DDT. The rest of the samples collected from the bay along with Lagoon System D (Beach Haven West) did not show any detectable pesticides. All of the tributaries and the remainder of the Beach Haven West complex did show slight traces of DDT. The Bureau of Commercial Fisheries, at the Milford, Connecticut laboratory, reported that DDT, toxaphine, and aldrin were found to be very toxic to oyster and 7.33 clam larvae. Lindane, on the other hand, was almost nontoxic to these larvae, but it inhibited the growth of plankton organisms in their food chain when present in low concentrations. Smith (1972) reported DDT concentrations ranging from 1.15 to 3.70 ppm re- sulted in 55 to 98% mortality of winter flounder embryos and vertical deformaties in 2-44% of the hatched larvae. Concentrations of heptachlor, endrin, and lin- dane (0.3-0.4 ppb) killed or immobilized half of the adult commercial brown and pink shrimp (crustaceans) exposed in 48 hour laboratory tests. DDT and dieldrin showed similar effects at 1-6 ppb (Butler and Springer 1963). In mollusks such as the oyster, Calabrese (1972) reported that DDT at 0.05 ppm caused over 90% mortality of oyster larvae and almost completely prevented growth in the survivors. In studies of the upper Barnegat Bay system (Makai 1973), DDT and its meta- bolites were detected in concentrations ranging up to 300 ppb in fish and 2,234 ppb in sediment. The pesticide levels detected in the fish samples for both estuarine areas (Upper Barnegat Bay and Little Egg Harbor - Manahawkin Bay) did not exceed the FDA's established maximum permissable levels for human consumption. However, it would appear that DDT concentrations recorded during this study are in sufficient quantities to have sublethal effects on estuarine organisms. Analysis of the fish, shellfish, and sediment samples showed that all five heavy metal elements were present. Only slight traces (<0.01 ppm) of chromium were detected in the fish and shellfish meat. This was also the case for cadmium with the exception of two readings: 0.50 ppm and 0.75 ppm (detected in the hard clam and ribbed mussel, respectively). The concentrations of lead, zinc, and mer- cury detected in the fish samples were comparable to the levels found in the shell- fish samples (Table 163). Results also showed the hard clam to have slightly higher concentrations of zinc and mercury in the meat than the mussel. In fact, the highest heavy metal levels observed in the edible tissue of both the fish and shellfish were those of zinc. These levels were detected in the white perch netted in Mill Creek and the Atlantic menhaden collected in the Beach Haven West Lagoon Complex. Hard clams collected in the bottom waters near Main Point, Manahawkin Bay had 20 ppm levels and the ribbed mussels taken from Parker Run had concentrations of 17 ppm. The heavy metal concentrations in the sediment were found to be much higher than the other samples. Chromium and zinc were detected in all 30 of the mud samples. Of the five elements, lead was found in the highest concentrations. Such concentrations were observed in the subaqueous samples collected at channel light Flashing Green "21" and Meyers Pond (197.5 Dpb); Tuckerton and West Creeks (265 ppb); and channel light Flashing Green "53" and Cedar Run (237.5 ppb). Re- sults also showed that the upstream stations in most of the tributaries had higher levels of cadmium than the downstream sites (mouths). The highest levels of mercury were detected in the bottom samples collected in Dinner Point Creek (2.75 ppm); Meyers Pond and channel light Flashing Green "53" (2.07 ppm); Mill Creek (2.03 ppm); and Cedar Run (2.01 ppm). No high levels were detected in fish or shellfish (<0.4 ppm). In studies of the upper Barnegat system (Makai 1973), it was reported levels >1 ppm were detected in the bottom waters of Toms River near Pelican Island and in Forked River. Abnormally high levels of mercury are considered to be those exceeding the FDA established maxi- mum of 0.5 ppm for food and 0.005 ppm for water. According to Julian (unpublished 7.34 paper), hard clams taken from Barnegat Bay were found to have mercury levels ranging from 0.0 to 0.275 mg/kg in edible tissue and 0.0 to 0.3 mg/kg in the shell. The levels detected in the fish, shellfish, and mud are within the limits established by the FDA. Metals reach the marine environment by many ways, including natural weath- ering as well as municipal and industrial discharges. These metals are, in varying degrees, poisonous to humans and marine life, although some of them are essential in trace amounts to humans, as well as other animal life. Dow and Hurst (1972) have summarized from the literature effects of heavy metals on marine resources: Cadmium is extremely toxic to oysters, less toxic to hard clams, and moder- ately to all other animals. Pringle et al. (1968) reported a 15 week 50% lethal dose (LD50) of 0.1 mg/l and inhibition of shell growth for Crassostrea virginica. Cadmium also damages the intestinal tract, kidney, and gills of marine fish. It increases the toxicity of other metals. Lead is toxic to oyster gonads; it also adversely affects hard and soft clam reproduction. Toxic to most enzyme systems, lead causes 100% mortality to lobsters in tanks. It inhibits one cell algal growth at concentrations of 0.5 ppm in water and is 100% lethal in 7 days. Oyster larvae were killed by 3.0 ppm levels. Lead is extremely toxic to soft clams above 0.02 ppm in water. Zinc damages the gills of fish. It is toxic to oysters in very small amounts. Chromium is not toxic except in large concentrations. This would also vary with valence state, form, pH, synergistic or antagonistic effects from other con- stituents, and the species of organisms involved. It would appear that some of the heavy metal concentrations recorded in this system are in sufficient quantities to have sublethal effects on estuarine organ- isms. Twenty-four Hour Tidal Survey The objective of this study was to seasonally compare temperatures, salinity, and dissolved oxygen levels on an hourly basis for a period of 24 hours in a nat- ural versus artificial system. Dinner Point Creek, selected as the natural area, was very shallow (chart depths indicating 0.5 to 4.0 ft at mean low water). How- ever, just downstream from the first branch, water depths (measured with a fatho- meter) were about 5 ft at low water. As was previously mentioned, the lagoons within the Beach Haven West complex do not receive any fresh water input other than from storm drains or effluent pipes associated with the surrounding dwellings. The mouth of Lagoon 08, situ- ated in System A, was chosen as a station because of its close proximity to the bay area and its ready accessibility. Results from this survey can be found in Figures 10 to 21. In the natural drainage system where shallow depths are evident, it was found that air temperatures directly influenced water temperatures. As one would expect, surface and bottom temperatures were similar. In the lagoon complex, this 7.35 relationship was not evident. Surface and bottom readings varied throughout the survey. Water temperatures were stratified three out of the four periods. The spring survey revealed the greatest stratification; bottom waters remaining con- sistently colder with a 3.4 to 5.OOC difference over the 24 hour period. On the other hand, the fall survey showed little stratification (0.20C difference). Water temperatures during the extreme periods (winter and summer) were found to be less stratified, generally evident from early morning until late evening. During the winter, bottom waters were warmer than the surface (0.0 to 2.4')C dif- ference); the summer was just the reverse. Vertical temperature difference ranged from 0.5 to 2.50C. The results indicated the salinity distribution within the natural area is regulated by tidal flow and seasonal patterns. During the summer survey, low stream flows produce salinity levels ranging from 22.6 to 27.3 0/00. But during the spring (high flow period), salinity levels recorded ranged from 19.1 to 27.3 0/00. There was little variation between surface and bottom during the sampling. Unlike the cyclic salinity patterns observed in the tidal creek, the salin- ity distribution in the lagoon area was found generally to be uniform, with lit- tle variation. It would appear concentrations are dependent on wind agitation and seasonal dilution. Salinity levels, during the summer survey, ranged from 24.5 to 25.8 0/oo; whereas, the spring survey showed concentrations ranging from 24.1 to 24.6 0/00. On the other hand, dissolved oxygen profiles within the natural area ap- peared to be regulated according to seasonal conditions. During the summer sur- vey, dissolved oxygen levels were cyclic ranging from 2.0 to 7.5 mg 02/1. Oxygen levels are normally regulated by tidal flows and periods of photosynthetic activ- ity; however, peak levels occurred during flood tides regardless of illumination (Figure 20). Concentrations below 4.0 mg 02/1 were recorded only during the early morning hours. There was little variation over a 24 hour period. Concen- trations ranged from 8.0 to 10.1 mg 02/1 with the decline in levels recorded dur- ing the early morning. In the artificial area, large vertical differences in oxygen levels were found during both the summer and spring surveys. Bottom concentrations (0.0 to 8.0 mg 02/1) during these periods were found to be variable compared to the sur- face levels. This condition was not evident during the other periods. Surface levels during the survey appeared to be regulated by wind agitation and seasonal patterns. Concentrations did not fall below 5.0 mg 02/1. The distribution of temperature, salinity, and dissolved oxygen recorded in the artificial system seems to indicate circulation within this area is very poor at times. The water quality of such an area would be dependent on climatic con- ditions. Bottom waters during the spring and summer surveys were at times com- pletely void of oxygen. Such anaerobic conditions cannot continuously support a good benthic population. Thermal stratification was evident during three out of the four periods. Such conditions observed in some dredge holes (borrow pits) have been reported to attract overwintering finfish such as the white perch (Makai 1969). More research would be needed to completely evaluate the benefits of stratification within areas for overwintering populations. However, it has been observed that the white perch is one of the more common species found in the artificial systems (see preceeding Fish Studies report for more details). The fluctuation of anoxic conditions observed during the spring and summer peri- ods within the area would not be considered good water quality criteria for most of your living organisms. Only your more tolerant species could exist (e.g. eels and blue claw crabs). 7.36 Isohaline and Isotherm Distribution Figures 22 to 25 present isohaline and isotherm distribution patterns mapped both on an incoming and falling tide during the summer season. DISCUSSION Water temperatures recorded during the two survey periods (July 1973 - Febru- ary 1974 and June 1974 - May 1975) ranged from -2.7 to 30.50C. As one would ex- pect, the lowest extremes were observed during the months of January and February with the latter being the coldest month. The minimum temperature of -2.70C was recorded in Dinner Point Creek. It is interesting to point out that this was the only system where water temperatures fell below O.0�C for 5 consecutive months (December 1974 through April 1975). This tributary is very shallow and found with water depths ranging from 0.5 to 4 ft at mean low water. As was reported during the 24 hour tidal survey, water temperatures are greatly affected by air tempera- tures. Temperatures below 0.0�C were also recorded at stations WC-O and MC-0 (-0.50C); MB-9 and T-8 (-1.00C); and the thermograph station located near Long Point (ranging from -2.2 to -1.70C). Water temperatures at or above 29.50C (850F) were observed at the following stations: MB-8, MB-O, MC-O, PP-O, BHW-6, and BHW -10 (29.50C); DPC-3 and BHW-5 (30.0�C); and MC-6A (30.50C). The maximum tempera- ture of 30.50C was recorded in Lagoon 91 (MC-6A) during the month of August. Temperatures monitored at Beach Haven Inlet (Flashing Light "92") were con- sidered representative of ocean temperatures. The inshore bays, characteristically shallow, are greatly influenced by air temperatures. The data show that seasonal trends were consistent within this system as observed during previous studies con- ducted within the coastal waters of New Jersey. During the summer, ocean waters were cooler than inshore regions; however, in September average water temperatures were found to be similar with the exception of Dinner Point Creek (Figure 26). Temperatures observed in this tributary were somewhat cooler as compared to the other areas. This trend was observed during the periods October 1973 to March 1974 and September 1974 to April 1975. Generally, water temperatures gradually decreased from the end of September through December. In January and February, severe cold conditions caused abrupt changes in water temperatures, after which mean temperatures began to steadily increase from March on. Water temperatures along the western portion of the bay are greatly influ- enced from the tributary drainages (see Figure 26). The bay area showed only small vertical temperature gradients generally not differing more than 0.60C between the surface and the bottom. The only exception was a difference of 1.80C recorded during September 1973. Typically, during the warmer months, water temperatures tended to increase from Beach Haven Inlet to the Manahawkin Causeway. Thermal stratification was evident during both the summer and winter periods in some of the artificial systems. Late spring and summer temperatures were found to be much more stratified with bottom temperatures showing more variability than the surface e.g. Stations BHW-2, BHW-3, BHW-6, BHW-8, and MC-5. The highest verti- cal temperature difference, 16.70C was observed at BHW-6. 7.37 Not all stations within the artificial complex were found to be thermally stratified. Only station BHW-6, the farthest upstream site in System B, was con- sistently stratified throughout the study. This was also the case in the channel of Mill Creek, but to a lesser degree. Salinity patterns were similar to the water temperature stratification ob- served in Mill Creek insofar as the effects of fresh water intrusion in this sys- tem. It is interesting to point out that the bottom waters of lagoon stations MC-4 and MC-5 were found to have salinity levels greater than the downstream chan- nel station MC-3. In the lagoon complex, vertical salinity stratification was less pronounced but nevertheless evident. Bottom levels measured in some lagoons were also found to be higher than the downstream station, e.g. station BHW-2, BHW-3, BHW-6, and BHW-8. In the bay, salinity levels recorded for the surface and bottom waters were found to be similar; vertical differences never exceeded 2.1 �/oo. The highest salinity levels were recorded at Beach Haven Inlet (32.0 0/oo). This station had a range of 27.5 to 32.0 �/oo. The salinity differences from Beach Haven Inlet to the Manahawkin Causeway (Rt. 72) were never more than 8.9 �/oo. Except for one reading of 19.8 �/oo, levels were never less than 20.0 �/oo. Generally, average levels between tidal stages within the artificial areas were similar (see Figure 27). Overall averages from June to December ranged from 24 to 25.6 0/oo with the exception in September when levels were around 23.0 �/oo. From midwinter through spring, when climatic conditions influenced tidal dilution, average levels were between 21.0 to 22.0 �/oo. Average salinity levels were higher in Dinner Point Creek as compared to Mill Creek. Average levels were also somewhat higher in the artificial areas than the natural system. Station DPC-3, the farthest upstream site in Dinner Point Creek, was found to undergo the greatest salinity fluctuation (3.3 to 26.2 �/oo). Sta- tion MC-6, the farthest upstream station in Mill Creek was observed to have a range of 0.3 to 14.7 0/oo. Oxygen levels recorded in the artificial systems were found at times to be extremely stratified and variable. This condition was not evident at those sta- tions situated at the mouths of the lagoon complex (e.g. stations BHW-1 and BHW- 9). All of the submerged waters within the artificial system (excluding stations BHW-1, BHW-5, and BHW-9) were found at some period of the survey to have oxygen levels less than 3.0 mg 02/1. Such concentrations are critical for many living organisms. This also was true for Stations MC-4 and MC-5 located in Mill Creek. Anoxic conditions (<1.0 mg 02/1 within the lagoon complex) were found at depths ranging from 7 to 26 ft. Almost 50% of these readings were observed at water depths over 15 ft (depths usually observed in the channel). Depths less than 15 ft were found in the distal end of the lagoons. Station BHW-6, in System B, had oxygen levels above 4.0 mg 02/1 only during the months of October and Novem- ber. The rest of the year, the bottom waters were void of oxygen. In the bay, some vertical oxygen stratification was evident but to a lesser degree. Surface oxygen levels were found to vary. Levels recorded in the lower bay area were generally lower than concentrations observed in the upper bay. 7.38 Concentrations were never detected below 5.4 mg 02/1. In the natural area, oxygen levels below 5.0 mg 02/1 were measured during the study. This was very evident during the summer months and to a lesser degree in the fall. It is interesting to note that levels as low as 2.8 mg 02/1 were ob- served during the fall sampling of the first study period. Normally, oxygen levels during this time of year are found to be around 9.0 mg 02/1. The data show that the farthest upstream station (DPC-3) had reduced oxygen levels throughout the year. The second study again showed reduced oxygen levels in this system. Except for stations DPC-3 (the farthest station upstream), the data suggest reduced levels to be consistent with ebbing tides. It would appear from the reduced levels observed at this station, the area is stressed with respect to oxygen concentration during certain periods of the season. Only once were the deeper bottom waters of the main channel of Mill Creek found to have levels below 3.0 mg 02/1. However, at stations MC-4 (undeveloped) and MC-5 (developed lagoons), large differences in surface and bottom oxygen levels were observed. Bottom waters generally had low or nonexistent levels of oxygen. Surface concentrations during the summer period were found to be extremely high (15.0 mg 02/1). High surface dissolved oxygen levels were also observed in Tuckerton Creek and Parker Run. Oxygen levels of 15.0 mg 02/1 or more were observed in Tuckerton Creek at Station TC-2 (16.2 mg 02/1), TC-4 (16.8 mg 02/1), and TC-5 (17.1 mg 02/1) during October. In Parker Run, at station PR-4, high levels were observed in February (15.9 mg 02/1) and April (16.8 mg 02/1). There were other stations ex- hibiting unusually high surface oxygen levels; however, such concentrations did not exceed 15.0 mg 02/1. High concentrations (in mg 02/1) were observed at sta- tions TC-4 (14.4), TC-5 (10.3), and TC-6 (13.3) during July and in Parker Run at stations PR-3 (12.6 and 13.1), PR-4 (14.5), and PR-5 (14.9 and 12.2) during April. Anoxic conditions were also observed in some of the bottom waters of these two tributaries during the summer period (e.g. stations TC-2, TC-6, PR-4, and PR-5). The waters of Westecunk Creek and Cedar Run were also found to be stratified. Reduced oxygen levels, evident primarily during the warmer months, were limited to the upstream stations of both tributaries (e.g. stations WC-3, WC-4, WC-5, CR-2, and CR-3). The oxygen data is plotted for each system in Figure 28. The pH levels measured in the bay were basic or nearly so. There was little difference between surface and bottom readings. Maximum levels recorded in the bay were found in the waters at stations MB-1 (pH=8.65) during August; MB-5 (pH= 8.5) and T-2 (pH=10.0) during October; and MB-9 (pH=8.5) during October and May. In the natural area, pH readings ranged from slightly acid to basic with the exception of station DPC-3, where levels were found to vary from acid to near basic. In the artificial system (the lagoon complex), pH levels ranged from slightly acid to basic. Readings above 8.5 were only recorded in Mill Creek at stations MC-3 (8.7), MC-4 (8.5, 8.8, and 8.9) and MC-5 (8.5 and 8.9); except for station MC-4 with a reading of 8.8 (recorded in July), all the other values were measured 7.39 during August. Mill Creek was also found to have the lowest pH in the system (5.7 recorded at Station T-18). Readings above 8.5 were observed in Tuckerton Creek and Parker Run. The highest pH measurements in the tributaries during the two study periods were at station TC-6 (9.0 and 9.15 during the month of July). Other readings were taken during this period at station TC-2 (8.55) and TC-5 (8.65). In Parker Run, during April, pH values of 8.72 and 8.5 were observed at stations PR-4 and PR-5, respec- tively. Average surface carbon dioxide concentrations were lowest in the bay area as compared to the other systems (Figure 29). Both Mill Creek and Beach Haven West were found to be similar insofar as levels were lowest during the summer months and increased as winter approached. A gradual decrease in February was followed by an abrupt increase in April and a subsequent rapid decline. In the Dinner Point Creek system, this pattern was reversed. During the summer, carbon dioxide levels gradually increased until August and then slowly decreased with the onset of the winter period. From February through June, the levels were very similar. The highest concentration was detected at station DPC-2A (36.3 mg C02/1). Average Secchi disc values were greater in the artificial system than in the natural areas. Except for maximum depths recorded at stations BHW-2 (8 ft 6 in), BHW-7 (11 ft), and BHW-8 (10 ft) during the first survey, depths never exceeded 6 ft 6 in during the second period. Dinner Point Creek being shallower with a soft mud bottom, was found at times to be extremely turbid. Light penetration never exceeded 4 ft 6 in. Average readings ranged from i to 2 ft. Transparency values generally were high in the bay. Maximum depths or areas of greatest light penetration were Beach Haven Inlet at 10 ft (MB-1) and Sandy Island at 9 ft 6 in (MB-11A). Biochemical Oxygen Demand (B.O.D.) values recorded during the two study periods were found to be good. Generally, average B.O.D. levels were high during the summer period but gradually dropped going into the fall (Figure 30). However, during November 1974, there was an abrupt increase followed by a decrease going into the spring. It has been suggested that a clear stream or harbor should not have a B.O.D. of greater than 4.0 ppm (Lackey 1958). Only during the second study period did concentrations exceed 4 mg 02/1. In the artificial system, B.O.D. values generally were found to be higher than the natural area. The drainages (main stem) of Mill Creek and Dinner Point Creek had similar mean levels; however, station MC-6A (Lagoon 91) located in Mill Creek, was found during November to have a B.O.D. value >12.0 mg 02/1. On the other hand, neither Dinner Point Creek nor the bay area concentrations exceeded 6.0 mg 02/1. Nitrite nitrogen was detected only during 2 months of the two studies. The concentrations detected were negligible; 0.036 mg N02-N/l was the highest level detected. The nitrate nitrogen values measured during the first survey period (July 1973 to February 1974) were extremely high. Such unusually high readings were considered unrealistic and were omitted from the data. Data collected during the second sur- vey showed Dinner Point Creek to have higher nitrate levels than the artificial systems. Peak levels (0.97 - 3.98 mg N03-N/1) were observed at the farthest up- stream station, DPC-3. Concentrations were found to be consistently higher at this 7.40 station. The data also showed average levels recorded in Mill Creek to be slightly lower than the bay. The highest level observed in the bay was 0.94 mg N03-N/1 recorded at Station MB-9. Ammonia nitrogen levels, when detected, were found to be very low (0.0 to 0.4 mg NH3-N/1). During the first survey period, only small amounts were gener- ally found. Concentrations were found to be even lower during the second survey period as compared to the initial survey (0.0 - 0.16 mg NH3-N/1). It was during the second survey that no ammonia nitrogen was detected in the bay area. The only levels observed in Dinner Point Creek were detected at station DPC-3. With the exception of one reading (<0.01 mg NH3-N/1) there was no ammonia nitrogen pre- sent in the artificial systems during the second period. In Mill Creek, only the stations MC-3, MC-4, and MC-5 located above the sewage treatment facility showed traces of ammonia nitrogen. Small amounts of the soluble form of phosphate were detected (0.0 - 0.17 mg P04-P/1). During the first survey period, average levels were highest in Septem- ber. The second period showed maximum levels occurred during the month of Novem- ber. It was also during this month that the highest concentration, 0.17 mg P04- P/l, was recorded at station MB-7. Detergent (MBAS) levels detected during the 1973-74 survey were all <0.2 mg/ 1. Because of such low levels, it was decided during the 1974-75 period to survey only a few selected stations. During this second survey period, concentrations were found to range from 0.0 to 0.34 mg/I. The effect of detergent concentrations of 0.5 ppm on fish life is believed to be minimal (Eisler 1965). Detergent values recorded were highest during the months of September, Octo- ber, and November. It was during the month of October that the maximum reading of 0.34 mg/i was recorded (at station DPC-3). As was reported earlier, the waters of the Manahawkin Bay - Little Egg Harbor system were found to be very productive by both the commercial and recreational clammer (also see the following Use Study). The State of New Jersey Health De- partment, Bureau of Shellfish Control, located at Leeds Point, Absecon, routinely inspects and analyzes the water quality of New Jersey's coastal bays and waters. Contamination is determined by the number of coliform bacterial counts. The total coliform median MPN (most probable number) of the water can not exceed 70 per 100 ml, and not more than 10% of the samples can ordinarily exceed a MPN of 230 per 100 ml for a five-tube decimal dilution test. However, there are other factors that also must be taken into consideration before a particular area is classified. It is equally important to conduct a hydrographic study of an area and if neces- sary to also include shoreline investigations. Even if the bacterial counts may be considered good, an area could be closed if other factors prove to be a danger to public health (Eisle pers. comm.).3 Naturally, overlying waters of shellfish areas are classified by standards developed by the U.S. Public Health Service and member states of the Cooperative Program for the Certification of Interstate Shellfish Shippers. The accepted standards are: J William Eisle heads the Shellfish Control Unit of the New Jersey Department of Environmental Protection. 7.41 0-70 Coliform bacteria per 100 ml of water - Clean 71-700 Coliform per 100 ml of water - Moderately Contaminated Over 700 Coliform per 100 ml of water - Grossly Contaminated Tables 164 to 169 lists coliform density in MPN/100 ml. Results indicate that coliform counts did exceed 700 MPN/100 ml in the Manahawkin Bay - Little Egg Harbor system (Tables 170 and 171). In the bay areas, both total and fecal coliform counts were low except for one total coliform count of 750 MPN/100 ml observed at station MB-5 during August. However, in the natural area (Dinner Point Creek drainage) several high total coliform readings were observed during the two survey periods (930 to 4,600 MPN/ 100 ml). Readings were consistently high at station DPC-3 during the summer and fall period. An attempt was made to try to determine what was the contributing source of pollution. Unfortunately, only one successful run was made to establish a fecal coliform-streptococcus ratio. No conclusive interpretation could be made; this particular test was conducted during a period of low readings (total coli- form counts). However, the results have suggested that there are traces of human influence. This area is also reported to support a good wildlife population. The low dissolved oxygen concentrations that have been monitored throughout the survey at this station may further indicate stress conditions. Determining whether present upland developments are the source of these organisms would necessitate further research. In Mill Creek, high total coliform counts were observed during September (930 - 4,600 MPN/100 ml) and once during November (1,100 MPN/l00 ml). The maxi- mum value of 4,600 MPN/100 ml was recorded at station MC-5 (Lagoon 98). As was previously mentioned, this system receives the treated effluent (secondary) of the Beach Haven West sewage treatment facility and the drainage from Manahawkin Lake. During September, high readings were observed both below and above the treatment plant. High fecal coliform counts were also recorded periodically in the upland drainage (91-2,400 MPN/100 ml). The fecal streptococcus tests, al- though limited, did suggest both human and animal influence. Several high total coliform counts were measured in the artificial complex (930-4,600 MPN/100 ml). Readings were found to be very sporadic. It is most probable, as suggested by the fecal streptococcus tests, that the duck population utilizing these lagoons was the major contributing factor. SUMMARY The Manahawkin Bay - Little Egg Harbor system study area was bounded on the north by a line from the mouth of Gunning River across the Intracoastal Waterway to Harvey Cedars and on the south by a line across Beach Haven Inlet from Shooting 1horofare to the southern tip of Long Beach Island. The survey concentrated on Little Egg Harbor , Manahawkin Bay, drainages of Dinner Point Creek, Meyers Pond, Popular Point, Mill Creek, and Beach Haven West Lagoon Complex. Also in- cluded were tributaries such as Tuckerton Creek, Parker Run, Westecunk (West) Creek, and Cedar Run. Water acreage for these areas surveyed were a total of 26,247 acres. The bay volume consisted of 28,889,370,202 gallons with a mean depth of 3.5 ft and a shoreline length of 75.8 statute miles, 7.42 It was estimated that a total of 15,922 acres of wetlands are located within the study area. The portions that are state owned are the Great Bay Boulevard Wildlife Management Area (3,789 acres) and the Manahawkin Wildlife Management Area (965 acres). Also included are Federally owned and/or managed property such as the wetlands extending south of Mill Creek (3,800 acres) and the Gunning River Refuge (3,506 acres) which is adjacent to the Manahawkin Tract. According to the Wetlands Inventory by the New Jersey Department of Environ- mental Protection, 12 plant species have been identified in the study area: Spar- tina alterniflora (tall and short salt marsh cordgrass), Spartina patens (salt- meadow cordgrass), Iva frutescens (hightide bush), Baccharis halimifolia (sea myr- tle), Distichlis spicata (spike grass), Juncus gerardi (black grass), Panicum vir- gatum (switch grass), Scirpus olneyi (threesquare), Phragmites australis (common reed), Typha spp. (cattail), and Spartina cynosuroides (salt reed grass). A total of 16 lagoon systems have been identified. This would account for 2,061.6 acres of development resulting in 48,000 ft of developed shoreline. This water system is one of the cleanest and most productive estuaries along the New Jersey coast. Of the 34,789 acres between Beach Haven Inlet and Barnegat Inlet, only 2,480 acres are condemned. Commercially important shellfish found with- in the system include the hard clams, Mercenaria mercenaria; bay scallop, Argo- pectin irradians; and blue mussel, Mytilus edulis. Of these, the hard clam is the most important. Because of its abundance, the hard clam supports more shell- fishermen than any other shellfish within this system. The soft clam, Mya arenaria, and the eastern oyster, Crassostrea virginica are also found within this system but are not of commercial importance. Water temperatures ranged from -2.7 to 30.50C. The demonstrated seasonal trends were consistent with those observed during previous studies conducted with- in the coastal waters of New Jersey. The lowest temperature extremes were recorded during the months of January and February and the highest extremes during August. The bay area showed very little vertical temperature difference; generally not ex- ceeding more than 0.60C. Thermal stratification was evident during both the summer and winter periods in some of the artificial systems. Some water columns had a vertical temperature gradient of 16.70C. Salinity ranged from 0.3 to 32.0 0/oo with the highest averages observed during the fall months. In the bay, salinity levels recorded for the surface and bottom water were similar; vertical differences never exceeding 2.1 �/oo. The salinity differences between Beach Haven Inlet and the Manahawkin Causeway were never more than 8.9 �/oo. Except for the reading of 19.8 0/oo, levels never dropped below 20.0 0/oo. In the lagoon complex, vertical salinity stratification was less pro- nounced but nevertheless evident. The bottom levels measured in some lagoons were also found to be higher than their downstream counterparts. The maximum salinity fluctuation recorded in the surface waters by any one station was at station DPC-3, the farthest upstream sampling location in Dinner Point Creek (3.3 to 26.2 0/00). Dissolved oxygen levels ranged from 0.0 to 17.1 mg 02/1. In the bay, some stratification was evident but to a lesser degree. Concentrations were never detec- ted below 5.4 mg 02/1. However, in Dinner Point Creek, levels below 5.0 mg 02/1 were measured during the summer months and to a lesser degree in the fall. Reduced oxygen levels were consistently observed at station DPC-3 (farthest site upstream) during a falling tide. 7.43 All of the submerged waters within the artificial systems (excluding BHW-I, BHW-5, and BHW-9) were found at some period of the survey to have oxygen levels less than 3.0 mg 02/1. Anoxic conditions (<1 mg 02/1) were found at depths ran- ging from 7 to 26 ft. Nearly 50% of these readings were observed at water depths over 15 ft (depths usually observed in the channel). The bottom waters of Sta- tion BHW-6 in System B were found with oxygen concentrations above 4.0 mg 02/1 only during the months of October and November. At Mill Creek, on the other hand, only once were the bottom waters within the main channel found with oxygen below 3.0 mg 02/1. Lagoon stations MC-4 and MC-5, both located in this tributary, were generally observed with bottom water oxygen concentrations greatly reduced or absent. During the summer period, sur- face levels were found to be extremely high (15.0 mg 02/1). High surface levels (15.0 mg 02/1 or more) were also observed in Tuckerton Creek and Parker Run during various portions of the survey. The pH readings throughout the Manahawkin Bay - Little Egg Harbor system ranged from 5.7 to 10.0. Normally, readings did not go over 8.5 except during the months of July and August. "Free" carbon dioxide levels were measured and ranged from 0.0 to 36.3 mg 02/1. Generally, average levels for the system were highest during the warmer months and lowest during the winter. Secchi disc values ranged from 3.0 in to 11 ft. Transparency values were generally high in the bay. Average readings were found to be higher in the arti- ficial system as compared to the natural area (Dinner Point Creek). Dinner Point Creek, being shallower with a soft mud bottom, was found at times to be extremely turbid. Light penetration never exceeded 4.5 ft. Biochemical Oxygen Demand (B.O.D.) values measured during the two study pe- riods were found to be good. Generally, average levels were high during the summer period but gradually dropped going into the fall. Levels ranged from 0.0 to 12.0 mg 02/1. Nitrite nitrogen (0.036 mg N02-N/l maximum) and ammonia nitrogen concentra- tions (0.0 to 0.4 mg NH3-N/1) were very low. Nitrate nitrogen levels recorded during the second survey ranged from 0.0 to 3.98 mg N03-N/l. High concentrations (0.97 to 3.98 mg N03-N/1) were consistently measured in Dinner Point Creek (station DPC-3). Generally, levels in the system were found to be higher during the fall rather than the winter season. Small concentrations of orthophosphate were detected (0.0 - 0.17 mg P04-P/1) the highest level being recorded in the bay at station MB-7. Slight traces of detergent were detected within this system ranging from 0.0 to 0.34 mg/I. A bacterial monitoring program showed that total coliform counts ranged from <3 to 4,600 MPN/100 ml and fecal coliform from <3 to 2,400 MPN/100 ml. In the bay areas, both total and fecal coliform counts of 4,600 MPN/100 ml were observed in Dinner Point Creek, Mill Creek, and in the lagoon complex. Determining wheth- er animal or human influence was the contributing factor would necessitate further research. 7.44 Results of residue analysis for the chlorinated hydrocarbon showed slight traces of DDT and its metabolites were detected in 34.6% of the fish samples with values ranging up to 17 ppb. Only 20% of the shellfish meat showed any traces. None of the other insecticides were detected in either fish or shellfish meat. DDT and its metabolites were detected in 76.6% of the sediment samples. Concentrations ranged up to 69 ppb. The only other insecticide observed was heptachlor epoxide (detected in 33.3% of the samples). Analysis of fish, shellfish, and sediment samples showed that all five ele- ments were present. Only slight traces (<0.01 ppm) of chromium and cadmium were detected in the fish meat. Lead ranged from 0.0 to 6.1 ppm, zinc from 5.65 to 16.85 ppm, and mercury from 0.0 to 0.4 ppm. Only slight traces of chromium (<0.01 ppm) were detected in the shellfish samples. Cadmium ranged from <0.01 to 0.75 ppm; lead ranged from 0.0 to 5.7 ppm, zinc ranged from 2.5 to 20.0 ppm, and mercury from 0.0 to 0.29 ppm. In the sediment samples cadmium ranged from 0.0 to 3.0 ppm, chromium from 3.0 to 50.0 ppm, lead from 0.0 to 297.5 ppm, zinc from 2.0 to 66.6 ppm, and mer- cury from 0.0 to 2.75 ppm.

Himchak ABSTRACT The use study of the Manahawkin Bay - Little Egg Harbor system was designed to determine the ways in which the estuarine system is used; the estimated total man-days of activity for each major type of user-group; expenditure estimates for various user-groups; and an estimated resource harvest for the entire system. Aerial surveys, bag and creel surveys, and expenditure surveys were the three integrated survey methods utilized to obtain data for the above determina- tions. For the 8 month study period, July 1973 to February 1974, resultant tabu- lations show that an estimated 158,269 man-days of activity had occurred within the study area. During which an estimated 446,754 fish (including crabs), 14,365,902 shellfish, and 306 waterfowl were harvested at an estimated cost to those involved of $835,222.55. During a second sampling period from June 1974 to May 1975, excluding November and December 1974, an estimated 230,326 man-days of activity occurred within the study area with an estimated total harvest of over 450,000 fish (including crabs) and over 19 million hard clams. An estimated $2,206,033.04 were spent by those persons using the study area during this time period. ACKNOWLEDGEMENTS The use study of Manahawkin Bay - Little Egg Harbor was initiated by Assistant Fisheries Biologist Bruce A. Halgren. The study continued under his supervision throughout the initial 8 month period (July 1973 to February 1974) and during the first 7 months of the 12 month period (June 1974 to January 1975). Upon his transfer to a different project, I assumed leadership of the study. Fisheries Worker Russell Tilton performed most of the field work throughout the 20 months of sampling. His enthusiasm and dedication is most appreciated. Principal Fisheries Biologist Paul E. Hamer is also acknowledged for his supervisory assistance and recommendations. The assistance with field work by other laboratory personnel is also greatly appreciated. Those of assistance include: Senior Fisheries Workers Jeffrey Carlson and Keith Lockwood; Fisheries Workers Barry Preim and William Andrews; and Summer Worker Frederick Bubeck. INTRODUCTION This study is an attempt to estimate the extent and types of all major estuarine activities occurring within the ?4anahawkin Bay - Little Egg Harbor system. Under the continuing Estuarine Evaluation Project the Bureau of Fisheries is conducting an intensive survey and inventory of all the major New Jersey estuaries, usually allocating an entire year for each system. Mana- hawkin Bay - Little Egg Harbor represents the fifth major estuarine system to be studied under this project. 7.49 The study area covers tidal waters and associated marshlands with the up- land treeline serving as an easily recognizable boundary line. It is within these areas that most activities affecting estuarine resources are conducted. Covering the entire watershed was prohibitive due to insufficient manpower. The northern boundary of this study area was Sandy Island in Barnegat Bay (roughly the same latitude as Harvey Cedars). Little Egg Harbor Inlet and Great Bay Boulevard were the southern limits of the survey area (Figure 31 which can be found in Appendix A). Activities performed on the bay side of Long Beach Island such as bank fishing were included, whereas those activities such as surf fishing on the ocean side of the barrier island were not considered. The survey attempted to determine how the estuary is used by man, both commercially and recreationally; the different types of user-groups3; an esti- mated total man-days3 for each activity; total resource harvest and total ex- penditures by the different user-groups. There is also presented a comparison between the total use picture of the Beach Haven West lagoon community and the adjacent natural marsh. Initially, an 8 month study of the Manahawkin Bay - Little Egg Harbor system was conducted from I July 1973 to 28 February 1974. This was followed by a sim- ilar 12 month study of the same area from I June 1974 to 31 May 1975. The 3 month interim was due to administrative scheduling for report writing. This report presents the results of 20 months of field work covering both study periods. DEFINITIONS The following list of terms and their definitions are presented for clarity and understanding of segment areas, activities, and other terms appearing throughout this report. This list originally appeared in the Nacote Creek Re- search Station Miscellaneous Report No. 14M, Eight Month Study of the Little Egg Harbor - Manahawkin Bay System, and is reproduced here in its entirety. 1) Bank fisherman is any individual fishing or crabbing without a boat. 2) Beach Haven West is the lagoon community located on the west side of Manahawkin Bay, south of State Highway 72, and north of Mill Greek (Figure 31: Section A). For the purposes of this study, only those activities occurring within the tidal waters (lagoons) of the community or those activities directly involved with the tidal waters, such as bank fishing, were included on the aerial survey data sheets (i.e. ac- tivities such as backyard barbecues were not included). 3) Boat fisherman is any individual fishing or crabbing from a boat of any type, size, or description. 4) Boating is any boat, the occupants of which were not obviously engaged in, or had engaged in fishing, shellfishing, water skiing, or hunting. 3Consult definitions section for an explanation of these terms. 7.50 5) Catch per effort is the average number of fish or shellfish caught per hour of fishing or shellfishing (fish per man-hour) unless otherwise stated such as catch per man-day. 6) East Little Egg Harbor is that portion of the study area bordered on the south by Little Egg Inlet; on the west by a line from Tucker Island sand bar to Goosebar Sedge to East Sedge Island to Shelter Island; on the north by a line from Long Point to Marshelder Islands; and on the east by Long Beach Island (Figure 31: Section 3). 7) East Lower Manahawkin Bay is that portion of the study area bordered on the south by a line from Long Point to the Marshelder Islands; on the north by State Highway 72; on the east by Long Beach Island; and on the west by a line from Shelter Island to Cedar Bonnet Island (Figure 31: Section 4). 8) East Upper Manahawkin Bay is that portion of the study area bordered on the south by State Highway 72; on the north by a line from Dipper Point to Maiden Land in the Borough of Harvey Cedars; on the west by a line from Cedar Bonnet Island to Sandy Island; and on the east by Long Beach Island (Figure 31: Section 5). 9) Hours per angler is the average number of hours spent per fishing trip. 10) Man-day is an indeterminate length of time an individual spends on the study area during any day. 11) Natural marsh is that portion of section 1 of the study area that is bordered by Mill Creek on the north; Meyers Pond Creek on the south; and the upland tree line to the west (Figure 31: Section B). Boats involved in activities in very close proximity, (within 10 to 20 ft) to the shoreline of the marsh were also included in this section. 12) Others is any activity that was either unknown or which did not fit in the listed categories of major user-groups. This would include, but is not limited to sightseers, bird watchers, hikers, naturalists, pic- nickers, and nonfishermen (with groups of bank fishermen). 13) Shellfishing is any individual harvesting clams, oysters, scallops, or mussels. 14) User-group is a major activity category and its participants, such as bank fishermen, boat fishermen, etc. 15) West Little Egg Harbor is that portion of the study area bordered on the north by a line from Long Point to the Marshelder Islands; on the south by Great Bay Boulevard; on the west by the upland tree line; and on the east by East Little Egg Harbor (Figure 39: Section 2). 16) West Lower Manahawkin Bay is that portion of the study area bordered on the north by State Highway 72; on the south by a line from Long Point to the Marshelder Islands; on the west by the upland tree line; and on the east by East Lower Manahawkin Bay (Figure 39: Section 1). 7.51 17) West Upper Manahawkin Bay is that portion of the study area bordered on the south by State 'Highway 72; on the north by a line from Dipper Point to Maiden Lane in the Borough of Harvey Cedars; on the west by the up- land tree line; and on the east by East Upper Manahawkin Bay (Figure 31: Section 6). Table 172 is a subsection of this definition list that also appears in the above mentioned Miscellaneous Report No. 14M and includes those species of fish and shellfish harvested by sport and commercial fishermen interviewed in the study area. Note that Tables 172 to 249 which relate to the use study can be found in Appendix B. METHODS Three integrated methods were employed to accomplish the objectives of the use study. Aerial surveys provided the data for monthly estimates of total man- days of activity within the study area. Bag and creel surveys yielded total harvest estimates for the study area. Expenditure surveys enabled the calcula- tion of per trip expenditures and total expenditures for the different user- groups. In addition, a survey was initiated in June 1974, to determine the geo- graphical origin of the different user-groups in the study area. A detailed presentation of the methods employed is given below. Aerial Survey Three aerial surveys were scheduled weekly, two on weekdays and one on a weekend day or holiday. The days for scheduling of flights were randomly chosen. Due to the greater recreational pressure on weekend days these data were segre- gated from weekdays data. Holiday flight data were treated as weekend days due to similar recreational pressure. During January and February of both study periods, sampling frequency was reduced to one weekday flight and one weekend flight per week to minimize ex- penditures during minimal activity periods. This practice went into effect after the last day of duck hunting season in January. Also, there were no aerial sur- veys conducted during November 1974 and December 1974 when monies allocated to this study were temporarily exhausted. All flights were randomly scheduled between 1000 and 1500 hours, considered the greatest activity period of the day (Briggs 1962). It should be realized that the estimate of total man-days of activity will be low since user-groups utilizing the study area only during the early morning or late afternoon hours were not accounted for. No adjustments were made to monthly estimates to cor- rect for this. The survey area was divided into eight sections: East and West Little Egg Harbor, East and West Lower Manahawkin Bay, East and West Upper Manahawkin Bay, Beach Haven West, and the natural marsh. These divisions within the survey area facilitated counting and provided better understanding of areas of activity. These areas are described in the preceding definitions section and are shown on Figure 31. Nine major activities were tallied for each section of the survey area to better understand where the different activities were being performed. These activities include: bank fishing, boat fishing, boating, shellfishing, 7.52 bathing, sailing, water skiing, hunting, and trapping, with all other activities listed in a miscellaneous category (others). All survey flights followed the shoreline within the survey area at an aver- age altitude of 500 ft. A single pass through the survey area was generally the rule. Deviations from the flight plan sometimes became necessary to more accu- rately count large numbers of boats or persons, to clarify the type of activity being performed, or to locate waterfowl hunters. Altitude, ranging from 200 to 700 ft, was influenced by visibility and areas of high population density. Attempts were made to reschedule those flights cancelled because of adverse weather conditions. Counts on foul weather days, if possible, would under- standably lower the man-days estimates. Corrections for these cancelled flights on bad weather days were not made. Some cancelled flights could not be resched- uled and were lost for the month. Boat counts were recorded on the field data sheets for the following activ- ities: boat fishing, boating, shellfishing, and sailing. Actual head counts of people were taken for bank fishing, bathing, water skiing, hunting, and trapping. The average number of persons per boat was determined on a monthly basis using the bag and creel survey data. Weekday means and weekend-holiday means of man-days of activity were com- puted by area and activity. These means were expanded according to the number of weekdays and weekend days/holidays in that particular month to determine a monthly estimate. Monthly estimates were computed for each activity in each of the eight sectors of the study area. Bag and Creel Survey To estimate the resource harvest per user-group, bag and creel surveys were conducted. Bank and boat fishermen, shellfishermen, hunters, and trappers were personally interviewed to determine the average catch per unit effort for each user-group. Three bag and creel surveys were scheduled weekly coinciding with the three aerial survey days. One of the two weekday surveys was allocated to bank fisher- men and the other to boat fishermen. The weekend survey was alternately sched- uled for bank or boat fishermen. During hunting season, one survey day each week was reserved for hunters. The type of survey for each day was randomly chosen. During periods of minimal activity within the study area, such as the winter months, a bag and creel survey would include all user-groups as well as expen- ditures of those user-groups. In conducting a bag and creel survey, the known access sites throughout the entire area were visited during the daylong survey. Transportation was by automobile. During the summer months, two interviewers were sometimes utilized, each covering half of the survey area. In addition, one boat by boat survey was scheduled weekly to obtain incom- plete trip data from boat fishermen, clammers, and hunters who might otherwise be missed during surveys by automobile. The number of boat by boat surveys was determined by weather conditions and boat availability at the laboratory. 7.53 For each bag and creel survey, the field worker interviewed as many people as possible during the course of the day. Only those persons engaged in their activity for a minimum of I hour were counted. This time of I hour was arbi- trarily considered the minimum angler or hunter trip to represent a true catch per effort ratio. The following data were obtained during a bag and creel survey: number of persons in the party; hours engaged in the activity per person; how many hours each individual planned to remain participating in that activity; and catch or harvest by number of each species. Bank fishermen were usually recorded singularly, while boat fishermen at access areas at the end of their trip were interviewed as a group. The number of anglers per boat was recorded and aver- aged monthly. These data were used to expand the boat counts taken during aerial surveys to arrive at estimates of total persons engaged in boat fishing, boating, and sailing. The average number of clammers per boat was determined from data taken on boat by boat surveys. Data derived from bag and creel surveys were summarized monthly. Harvest per effort for hunters and clammers and catch per effort for fishermen were determined from the above described data. Total harvest and catch estimates were calculated by integrating data from aerial surveys and bag and creel sur- veys. Expenditure Survey Expenditure survey data were used to estimate average expenditures of the major user-groups both on a per trip basis and for the year. Originally, expenditure data were collected during bag and creel surveys from one out of every four persons interviewed by the field worker. During the summer months, one survey day per week was randomly chosen for collecting expenditure data only. For the 12 month study period, an expenditure survey was scheduled weekly throughout most of the year. Data were collected on the following expenditures: bait, boat gas and oil, number of trips annually, miles traveled, and any miscellaneous fees. Food and lodging costs were prorated on a daily basis. For example, if a bank fisherman were paying for lodging by the week, one-seventh of this dollar figure was entered on the field data sheets for that day. To estimate the daily value of equipment, the person interviewed was asked to estimate the original cost of his equipment present, the average age of the equipment, and the number of times a year he uses the equipment present for the activity in which he was engaged. The original equipment cost was divided by the product of equipment age and number of trips annually to estimate equipment cost for that day's usage. The round trip mileage for using the estuary was multiplied by the appropriate number of cents per mile for the time period in which the activity took place. During the 8 month survey from July 1973 to February 1974, 5 cents per mile was multiplied by the round trip mileage to estimate car traveling expenses (De- partment of the Interior 1972). For the 12 month survey, June 1974 to May 1975, a figure of 12 cents per mile was used (Federal government allowance for em- ployees' traveling expenses). Expenditures data were summarized on a monthly basis to give expenditure means for expense categories, value of equipment, and miles traveled. These 7.54 means were subsequently multiplied by user-group estimates from the aerial sur- veys to estimate total expenditures for the different user-groups. Residence Survey An additional segment was added to the use study for the 12 month period, June 1974 to May 1975. This new survey was to determine the county or state of residence of those persons utilizing the survey area. If the person were from out of state, that particular state was recorded. The yearly percentages of persons residing in Pennsylvania, New York, and the individual counties of New Jersey who traveled to the Manahawkin Bay - Little Egg Harbor survey area either for recreational or commercial reasons were com- puted. People were interviewed for county or state residence during both the bag and creel survey and the expenditure survey. RESULTS Aerial Survey - Use Estimates Of all the flights scheduled during the 20 months of sampling, 72% were completed; 53 flights were cancelled due to inclement weather conditions. If it had been possible to obtain a count of persons using the study area on bad weather days, monthly estimates would understandably be lowered. As stated in the methods section, monthly estimates (as reported) of total man-days of ac- tivity are expected to be lower than the actual number since those persons using the study area during early morning and late day or night hours were missed altogether. The numbers of flights scheduled and completed during the 20 months of field sampling are listed in Tables 173 and 174. Of the 96 scheduled flights, 75% were completed during the 8 month study of the Manahawkin Bay - Little Egg Harbor system. During the 12 month study of the Manahawkin Bay - Little Egg Harbor system, 69% of the 94 scheduled flights were completed. In summation, the two time periods combined yield the data in Table 175. Results of the two study periods will first be presented separately. A comparison of the findings will then be made attempting to combine the 20 months of data into yearly estimates of total man-days of activity. EIGHT MONTH STUDY: JULY 1973 TO FEBRUARY 1974 -- The following use estimates for Manahawkin Bay - Little Egg Harbor during July 1973 to February 1974 are taken from the Nacote Creek Research Station, Miscellaneous Report No. 14M. During the 8 month study period, a total of 158,269 man-days of activity were spent on the study area (Table 176). Boat fishing was the most heavily engaged in activity in the study area and represented 42.25% of all activity in the study area. Even this figure, however, is considered minimal since a substan- tial portion of boaters, the second largest single category, were actually fishermen under way from one fishing ground to another, or between fishing grounds and a landing. Following boat fishing in popularity were boating (22.51%), shellfishing (11.75%), sailing (10.90%), bathing (5.56%), bank fishing (4.91%), others (1.11%), water skiing (0.68%), and hunting (0.34%). 7.55 The greatest activity demands upon the study area occurred during the summer. July (36.44%) and August (39.00%) accounted for over 75% of all the activity that took place during the 8 month study period. After the summer months, user activity declined steadily for the remainder of the study period. Tables 177 through 184 give estimated man-days of activity figures by area and activity for each month of the survey, while Table 185 gives the total esti- mated man-days of activity for the entire study period, also broken down by area and activity. These tables also present figures for that percentage of user-group activity that occurred in each area section (this figure appears as the upper percentage figure on the charts and is totalled across) and for that percentage of the total sector activity that each user-group represents (this figure appears as the lower percentage figure and is totalled down). East Little Egg Harbor accommodated the greatest activity demands placed on the study area (27.55%). This is due mainly to the fact that it contained the greatest percentage of boat fishermen and boaters, the two most popular user-groups. This section of the study area also accounted for the greatest amount of user activity in the category of others. The majority of the fishing done in this portion of the bay was by private boats with fluke being the most sought after and successfully caught species; weakfish, striped bass, and blue- fish were also taken. West Little Egg Harbor ranked second in overall activity and accounted for the greatest percentage of shellfishermen (42.77%) and bank fishermen (25.42%) and the second greatest percentage of boat fishermen and boaters. East Lower Manahawkin Bay ranked third in overall activity and accounted for the greatest percentage of sailors (32.28%) and bathers (43.89%) and the second greatest percentage of bank fishermen. West Upper Manahawkin Bay had the lowest percentage of overall activity, but had the second highest percentage of hunter activity. It also probably had the greatest number of boat rentals for fishing and crabbing, and undoubtedly produced the best crabbing in the study area. West Lower Manahawkin Bay accounted for only 14.03% of all activity in the study area but it contained the subsections of Beach Haven West and the natural marsh, and therefore deserves some special comment in this portion of the re- port. Table 186 shows the total man-days of activity estimates for the Beach4 Haven West and natural marsh subsections. Beach Haven West accommodated over 10 times the total amount of activity of the natural marsh. This figure may, however, be very misleading. Over 68% of the activity occurring in Beach Haven West was boating. It does not matter whether these boaters were on their way to go pleasure boating, boat fishing, or water skiing. It seems obvious that they were on their way somewhere else to enjoy their end activity. In this regard, the lagoon community was acting only as a docking facility. It is also probable that the sailboats encountered within the lagoon community were also in transit to the bay to fully realize the enjoyment of sailing, although moving under sail within the lagoon complex must test their skills to the utmost. The natural marsh subsection has a higher percentage of activity for only two activity categories. These are boat fishing, which makes up 0.70% of the 7.56 total boat fishing of West Lower Manahawkin Bay, and hunters which make up 27.20% of all area 1 hunters and 13.20% of all hunters within the study area. Tables 187, 188, and 189 show the distribution of bank fishing, boat fishing, and boating, respectively, for the 8 month study period by sector and month. TWELVE MONTH STUDY: JUNE 1974 TO MAY 1975 -- It is estimated that 230,326 man- days of activity were spent in the study area during 10 months of aerial sur- veys. Since no aerial surveys were conducted during November 1974 and December 1974, a yearly estimate of total man-days of activity is not presented in this section for the 12 month study period. Table 190 presents the estimated total man-days of activity by activity category and month. Tables 191 through 200 present the monthly estimates of man-days of activity for those 10 months in which aerial surveys were conducted. Boat fishing again accounted for the greatest percentage of activity, 46.56%. The remaining activity categories and their percentages are reported as follows: boating (22.00%), shellfishing (16.75%), bank fishing (6.91%), sailing (3.68%), bathing (3.34%), others (0.54%), water skiing (0.17%), and hunting (0.05%). The estimated total man-days of hunting activity, 117 man- days, appears to be a gross underestimate for the study period due to having data for only the month of October. By month, the summer months of July and August understandably accounted for over 60% of the total activity occurring within the study area. The months sampled and their corresponding percentage of the total estimated activity are as follows: January (1.10%), February (0.85%), March (2.42%), April (3.36%), May (4.54%), June (12.60%), July (28.26%), August (31.94%), September (10.13%), and October (4.80%). East Little Egg Harbor with the great recreational pressures of boat fishing and boating, accommodated the most activity, 28.90%. West Little Egg Harbor accommodated 27.35% of the activity during the study period, again, boat fishing (45.61%) predominating the activity. The greatest percentage of shellfishing (49.89%) occurred within this area. West Lower Manahawkin Bay, including Beach Haven West and the natural marsh area, accounted for 15.41% of all activity categories. Boat fishing and shell- fishing were the dominant activity. The greatest percentage of bank fishermen, 28.32%, was located in West Upper Manahawkin Bay. East Upper Manahawkin Bay contained the most bathers within the survey area (33.65%). Refer to Table 201 for a complete breakdown of activity by area and activi- ty category. Tables 202 through 204 present the distribution of bank fishing, boat fishing, and boating by area and month for the study period. A comparison of Beach Haven West and the natural marsh area is given in Table 205. Again, the boating estimate of 4,051 for Beach Haven West may be 7.57 misleading in estimating total activity f or that area. It is very likely that many of these boats were in transit from the lagoon community to participate in boat fishing, pleasure boating, or some other activity elsewhere. COMPARISON OF USE ESTIMATES FOR THE TWO SAMPLING PERIODS -- Aerial surveys were conducted each month of the 8 month study period. 'During the 12 month study of the same area, aerial surveys were conducted during only 10 of the 12 months due to temporary expiration of project funds. Consequently, only 6 months of the year were sampled twice as shown in Table 206. For those months which were sampled twice, the 12 month study shows an average increase of 16.27% over the 8 month study in total man-days of activity. This increase of 16.27% from the first study period to the second was used to estimate those months when no aerial surveys were conducted or the study was not in progress. This was done to provide two 12-month periods of total man- days of activity, thus giving yearly estimates of total man-days of activity for the two study periods. Yearly estimates were not previously given when each study period was analyzed separately. Table 207 lists the data for the two estimated yearly totals of man-days of activity. Table 208 is a comparison by activity category of estimated man-days of activity for the two study periods showing the totals for those 6 months which were sampled twice. The four major activity categories of bank fishing, boat fishing, boating, and shellfishing showed increases in man-days of activity of 60%, 26%, 24%, and 52%, respectively. These increases account for an additional 38,604 man-days of activity. Major decreases in use estimates occurred in the sailing and bathing categories, a decrease of 12,120 man-days of activity. The overall difference in use estimates for the two 6 month sampling periods shows a net increase of 24,847 man-days of activity when all activity categories are con- sidered. Bag and Creel Survey - Harvest Estimates EIGHT MONTH STUDY: JULY 1973 TO FEBRUARY 1974 -- The following harvest esti- mates are taken from the Nacote Creek Research Station, Miscellaneous Report No. 14M. A total of 1,878 persons were interviewed during the bag and creel surveys for this study period (Table 209). Bag and creel interviews, expanded to the extent of the use estimates in- dicate that over 4 x lO5 fish (including crabs), 9.5 x 106 clams, 4.5 x 101 bay scallops, and 300 waterfowl were harvested from the study area during the 8 month study period. Estimated total catch, catch composition, and catch per effort statistics on the above mentioned renewable resources are given in Tables 210 through 216. The boat fisherman accounted for 94.86% of the total estimated fish catch. The highest estimated boat catch occurred in July and decreased every month after that throughout the survey period. Boat fishing catch per effort peaked at over four fish per hour in October, but averaged only slightly above one fish per hour for the survey period. The blue claw crab constituted the most readily caught species and comprised 68.21% of the total catch. The fluke was4 undoubtedly the most sought after fish and was the second most plentiful 7.58 representative in the fisherman's creel at 13.12% of the catch. Bluefish (9.67%), blowfish (1.48%), and spot (1.37%) comprised the bulk of the remaining catch. Blue claw crabs accounted for the majority (79.36%) of the bank fisherman's catch. Bluefish (6.43%), fluke (4.66%), spot (3.30%), eels (0.97%), and weak- fish (0.97%) were also taken with fair success by the bank angler. The highest estimated bank catch occurred in July, and like the boat catch, decreased every month after that throughout the survey period. The best catch per effort oc- curred in November for the bank fisherman with 1.38 fish per hour. The survey long average was 1.02 fish per hour, slightly lower than that of the boat fish- erman. The "others" category of fish taken represented 1.82% of the total com- bined estimated catch and was mainly comprised of the oyster toadfish, northern sea robin, sandbar shark, and smooth dogfish. The bank fisherman had his highest estimated catch in July, which stands to reason since he also had more man-days of participation in July than any other month. The boat fisherman, on the other hand, had over 3,000 more man-days of participation in his sport in August than in July, but recorded a greater catch in July. This was due basically to better fishing (a better catch per effort ratio) and more hours spent on the water in July (a longer average man-day). The waterfowl harvest estimates given in this report are probably low. The aerial survey flights were scheduled randomly between 1000 and 1400 hours so that they occurred during the peak activity period (Briggs 1962). There is no doubt that hunters frequently entered and left the study area before and after the peak activity period, or to be more precise, before and after the aerial survey flight. Waterfowl hunters increase their success by being inconspicuous and staying out of sight of their prey. Thus, the skillful hunter may also have escaped observation by aerial survey and further lowered the estimated hunter activity and harvest figures. Hunter interviews were also difficult to obtain and low numbers of interviews could also cause inaccuracies in the survey. An estimated total waterfowl harvest of 306 birds was recorded on the survey area during the 1973 hunting season with a hunter success ratio of 0.11 birds per hour. The black duck (38.56%) and bufflehead (29.74%) comprised the bulk of the hunter's bag (Table 215). Shellfishing was the third most heavily engaged in activity within the study area during the 8 month survey, and during the winter months of December, January, and February, the most heavily engaged in activity. Sport and commer- cial shellfishermen harvested over 14.3 x 106 shellfish during that period. Shellfishing is the only year-round, heavily engaged in activity in the study area. It has high recreational and commercial interests; produces a highly valuable commodity; and the shellfishermen spent an estimated total of 96,000 dollars to engage in their activity for 8 months. This must be ranked as being among the top two or three more important human activities within the study area. Clams are harvested on a year-round basis. The highest harvest levels occur in the summer months when recreational and part-time commercial clammers swell the ranks. The highest catch per effort levels occur during the winter months when only the full-time experienced commercial clammers are active. 7.59 Scallops are harvested only during the open season which extends into the three cold weather months of November, December, and January. During this period, an estimated 4,658,326 bay scallops were harvested at an outstanding estimated catch per effort rate of over 776 scallops per hour (Table 216). TWELVE MONTH STUDY: JUNE 1974 TO MAY 1975 -- Data from over 2,500 interviews (Table 217) during bag and creel surveys were expanded to estimate total harvest for the Manahawkin Bay - Little Egg Harbor system. Total estimated bank fishing, boat fishing, shellfishing, and hunter harvest are presented in Tables 218 through 224 for those 10 months in which aerial surveys were conducted. It is estimated that over 4.5 x 105 fish (including crabs), and over 19 x 106 clams, were harvested within the survey area during a 10 month period. Hunter harvest figures are suspect due to the small amount of data taken only during the month of October 1974. Bank fishermen caught an estimated 46,594 fish (Table 218), 89.60% of which were blue claw crabs. Of the finfish species caught by bank fishermen, bluefish (3.90%), winter flounder (2.97%), and eels (0.82%), comprised the bulk of the catch. Less than 3.00% of the estimated total catch of bank fishermen was composed of species other than those mentioned above. The summer months of July and August accounted for over 60% of the 10 month total catch; again this was comprised mostly of blue claw crabs. Catch per effort figures for bank fishermen given in Table 222 show the greatest success in August and September, 1.79 and 1.77 fish (including crabs) per hour. The yearly catch per effort for bank fishermen was 1.32 fish per hour and was greatly influenced by the crabbing success of the summer months. Boat fishermen caught an estimated 412,287 fish, including 242,651 blue claw crabs, for the 10 months sampled (Table 29). The blue claw crab represents 58.85% of the total estimated catch. Following crab were fluke, 79,450 for 19.27%; bluefish, 31,112 for 7.55%; black sea bass, 21,590 for 5.24%; winter flounder, 15,222 for 3.69%; and weakfish, 11,390 for 2.76%. The total catch is based on the total estimated man-days for boat fishermen. It has been mentioned that a good percentage of those counted in the user-group, boating, were actu- ally boat fishermen in transit. Boat fishing man-days of activity for the 10 month period are estimated at 107,239 man-days. Total estimated catch is based on this figure. The boating category accounts for an estimated 50,682 man-days of activity. What percentage of these boaters were actually boat fishermen is not known. Therefore, the total estimated boat fishing catch is a low estimate. Catch per effort figures for boat fishermen (Table 221) are highest for Septem- ber, 1.66, and October, 1.93, when bluefish, black seabass, fluke, and weak- fish dominated the catch. The 10 month catch per effort average for both fish- ermen was 1.19 fish (including crabs) per hour. Table 220 shows the total estimated combined fishing catch composition for bank and boat fishermen for the 10 month period. Of the total estimated catch, 458,881 fish and crabs, boat fishermen accounted for 89.85% of the catch, com- pared to 10.15% for bank fishermen. Of the combined man-days of activity for bank and boat fishermen, 123,159 man-days, bank fishermen accounted for only 12.93% of the activity while boat fishermen accounted for 87.07%. Catch per effort comparisons show bank fishermen having slightly better success than boat fishermen, 1.32 to 1.19. Species listed in the "others" include sharks, sea robins, and oyster crackers. 7.60 Only 32 hunters were interviewed during the survey period, hunter activity being estimated at 117 man-days during the month of October 1974. Since no aerial surveys were conducted during November 1974 and December 1974, no esti- mate of total man-days of hunting activity is given. Table 222 represents the actual and estimated data for hunter harvest based on hunter interviews. Spe- cies harvested include the green-winged teal, mallard, black duck, and blue- winged teal (Table 223). State owned land in the Great Bay Boulevard area was surveyed by game biologists for waterfowl harvest during the 1974-1975 waterfowl hunting season (Widjeskog and Toth 1975). Only about half of the Great Bay Boulevard area sur- veyed under the above project is included in the Nanahawkin Bay - Little Egg Harbor survey area (the marshland north of the boulevard). For the entire Great Bay Boulevard area, hunters spent 2,129 days harvesting 854 ducks and 46 geese. Rail hunters harvested 524 clapper rails and 7 sora rails during an additional 221 days of hunter activity in that same area. Clamming total harvest estimates based on the 10 months of field data pro- ject a total of 19,177,104 hard clams taken from the Manahawkin Bay - Little Egg Harbor system (Table 234). The clamming harvest was estimated on a daily basis for each clammer interviewed and expanded based on the estimated man-days of clamming activity for each month. Catch per effort figures show the number of clams harvested per hour based on interview data. Clamming activity was highest during the month of July (9,878 man-days of activity), but showed the lowest catch per effort (44.43 clams per hour). Both the commercial and recre- ational clamming data are combined in estimating catch per effort and total harvest. Over 3 x 106 clams were harvested during the months of August and September, reflecting good catch per effort and man-days of activity figures. The best catch per effort occurred in the month of October when 205.67 clams were harvested per hour. COMPARISON OF HARVEST ESTIMATES FOR THE TWO SAMPLING PERIODS -- For the 6 months of the year which were sampled twice and have total harvest estimates, compar- isons are given in Tables 225 through 227. Bank fishing, boat fishing, and clamming harvest estimates are presented, as well as catch per effort figures. Hunter harvests were not compared due to insufficient data. Estimates of catch per man-day, as opposed to catch per man-hour, are used throughout this section of comparisons of total harvest estimates. Table 225 compares the estimated bank fishing catch by species for the two time periods: July, August, September, October 1973, January, and February 1974 against July, August, September, October 1974, January, and February 1975. The total estimated catch of Manahawkin Bay - Little Egg Harbor shows an increase of 79% from the first sample to the second a year later. However, total man- days of bank fishing activity increased 60% for the same time periods, from 7,503 to 11,997 man-days. When total catches are compared for an equal number of man-days of activity, the estimated bank fishing catches show an increase of 12%. The catch per man-day for the second time period shows an increase from 3.00 to 3.35 fish (including crabs) per man-day. Boat fishing harvest comparisons show a decrease of 24% from the first sampling period to the second. Adjusting total harvest estimates for equal numbers of man-days of boat fishing activity, a comparison shows an even larger 7.61 decrease in number of fish and crabs of 40%. Table 226 shows the comparison of harvest estimates by species. The bulk of the estimated harvest decrease was due to a substantial reduction in the blue claw crab catch from 289,052 to 187,193 crabs. Comparing estimated boat fishing catches for the two sampling periods excluding the crab catch figures reduces the percent difference in half from 40% to 20%. The closing or significant reduction in business of a large boat livery could produce such a drastic reduction in the catch of blue claw crabs. Also, reduced sampling at such boat liveries would also produce such a decrease in catch estimates. Catch per effort figures for the two sampling periods also show a decrease in numbers of fish (including crabs) per man-day of boat fishing activity (Table 226). Comparing catch per effort for total harvest estimates, there was a decrease from 6.47 fish per man-day for the first sampling period 1973-1974 to 3.90 fish per man-day for the second sampling period 1974-1975. Catch per effort figures for finfish species only show a decrease from 2.02 to 1.62 fish per man-day. Hard clam harvest comparisons are presented in Table 227. For an equal number of man-days for each sampling period, there occurred a 9% decrease in the total number of clams harvested. Total man-days of clamming activity increased 63% from the first sampling period, 1973-1974, to the second sampling period, 1974-1975. Total catch estimates increased only 49%. Adjusting either, total catch for an equal number of man-days of activity shows a 9% decrease in total number of hard clams harvested. Expenditure Survey - Expenditure Estimates EIGHT MONTH STUDY: JULY 1973 TO FEBRUARY 1974 -- Over 1,600 persons were inter- viewed for expenditure data during this sampling period (Table 228). Tables 229 through 232 present the estimated expenditures of bank fishermen, boat fishermen, sheilfishermen, hunters, bathers, and sailors. The following text analyzes these data and is taken from the Nacote Creek Research Station Miscellaneous Report 1414. An estimated total of 74,632 angler days were spent on the study area with an accompanying estimated $738,921.27 expenditure on the part of the anglers involved. This works out to be an expenditure of $9.90 per angler trip, in- cluding equipment costs. The estimated 446,754 fish (including crabs) taken by anglers over the survey period cost an average of $1.65 per fish. Boat fishermen spent an estimated $697,987.66 on an estimated 66,861 fishing trips for an average of $10.44 per trip or $1.65 per fish. Bank fishermen spent an estimated $40,933.61 on an estimated 7,771 fishing trips for an average of $5.27 per trip or $1.78 per fish. Shelifishermen spent an estimated 18,603 man-days on the bay at an esti- mated cost to the shellfishermen of $96,301.28 or approximately $5.18 per trip. An estimated 538 man-days were spent in the study area by hunters at an esti- mated cost of $8,676.35 or $16.13 per trip. Bather man-days were estimated at 8,795 with an accompanying expenditure of $29,204.15 for an estimated $3.32 expenditure per trip. Sailors enjoyed an estimated 17,250 man-days engaged at their sport at an estimated cost of $300,797.97 or $17.44 per trip. 7.62 Per trip expenses ranged from a high for sailors of $17.44 through hunters ($16.13), boat fishermen ($10.44), bank fishermen ($5.27), and shellfishermen ($5.18) to a low of $3.32 for bathers. Total estimated expenditure for all categories surveyed for expenditures for the 8 month survey period was $1,173,891.02. TWELVE MONTH STUDY: JUNE 1974 TO MAY 1975 -- Over 2,400 persons were inter- viewed for expenditure data during this sampling period (Table 233). Tables 234 through 237 present expenditure breakdowns for the major activity groups. Bank fishermen spent an estimated $116,464.95 for the 10 month period, June 1974 to May 1975, excluding November and December 1974 (Table 234). The average per trip expenditure of $7.33 consisted of $0.59 for bait, $0.62 for food, $0.48 for lodging, $0.40 for equipment, and $5.21 for traveling expenses. Other expenses included equipment rental and miscellaneous fees, a total of $0.04 per trip. The estimated total harvest for bank fishermen for this sam- pling period was 46,594 fish (including crabs). The cost per fish estimate was $2.50. Boat fishermen during this same time period spent an estimated $1,630,680.52 to harvest an estimated 412,287 fish (including crabs). This comes to $3.96 per fish. Per trip expenditures for a boat fisherman was esti- mated at $15.21 ($0.66 for bait, $0.54 for boat gas and oil, $2.05 for equipment rentals, $0.29 for food, $0.82 for lodging, $6.65 for equipment, $4.18 for traveling expenses and $0.02 for miscellaneous fees). Estimated total expendi- tures for boat fishermen are presented on a monthly basis in Table 235. Estimated total expenditures for shellfishermen, Table 236, were $209,924.95 for the above sampling period. The estimated per trip expenditure of $6.23 was comprised of $1.21 for boat gas and oil, $0.29 for food, $0.40 for related fees, $1.81 for equipment, and $2.53 for traveling expenses. Clamming expenditure data included both the year-long commercial clammer and the seasonal recreational clammer. It would be a fair assumption that the per trip expendi- ture for a commercial clammer would be less than the estimate of $6.23 due to reduced traveling expenses and equipment value, whereas the per trip expenditure of a recreational clammer would be more. Sailing expenditures were estimated at $23.24 per man-day of activity based on 85 interviews (Table 237). Of this estimated daily expense, $0.95 was for equipment rental, $2.39 for food, $3.27 for lodging, $0.44 for related fees, $5.98 for equipment, and $10.21 for traveling expenses. The total estimated expenditures for sailors for the 4 months of June, July, August, and September 1974 were $186,962.39. One hundred eighty-six bathers were interviewed for expenditure data. The bathing expenditure estimate of $8.15 per man-day of activity can be broken down into the following categories: $3.41 for traveling expenses, $3.00 for lodging, $1.69 for food, and $0.04 for miscellaneous fees. Total expenditures for the activity groups interviewed within the survey area for a 10 month period were estimated at $2,206,033.04. Expenditure data were not tabulated for those persons in the activity categories of boating, 7.63 water skiing, and the "*others" category. Hunter expenditure estimates are not given due to insufficient data. COMPARISON OF COST ESTIMATES FOR THE TWO SAMPLING PERIODS -- There is an in- crease in per trip expenditure estimates for all the major activity categories sampled during the two study periods (Table 238). The per trip expenditure estimates for the listed activity categories are broken down below into separate per trip expenses to better understand where expenditure estimates have in- creased. The most obvious increase is in traveling expenses where the per mile cost estimate has gone from $.05 for the first sampling period to $.12 for the second sampling period. Bait, equipment, and food expenses may have increased from one year to the next. Bank fishing per trip expenditures increased from $5.27 to $7.33 due largely to increased travel costs (Table 239). Boat fisher- men's per trip expenditure estimates went from $10.44 to $15.21, again due largely to travel expenses and also due somewhat to equipment cost increases (Table 240). Clamnmers' per trip expenditures increased from $5.18 to $6.23, travel cost extimates rose substantially while equipment costs decreased some- what (Table 241). Sailing again proved to be the most expensive activity with per trip expenditure estimates increasing from $17.44 to $23.24, even though equipment cost estimates were nearly half as much (Table 242). Bathers' per trip expenditure increased in every major expense category. The per trip expen- diture estimates of $3.32 and $8.15 are explained in Table 243. Hutr' per trip expenditure estimates are not compared due to insufficient data for the second sampling period, June 1974 to May 1975. Residence Survey Over 2,500 persons during the survey year, June 1974 to May 1975, were asked their county and/or state of residence, during either the bag and creel or ex- penditure surveys. The yearly summarization of these data appears in Table 244. New Jersey residents accounted for 70.75% of the sportsmen using the Manahawkin Bay - Little Egg Harbor system who engaged in either bank fishing, boat fishing, or clamming throughout the year. Pennsylvania residents accounted for 24.19% of the total; New York, 4.62%; and other states, 0.44%. Over half the total number of persons interviewed were bank fishermen. Tables 245 through 248 give a seasonal breakdown of the place of residence for persons using the survey area during four 3 month intervals. The percentages of those persons residing in the separate counties within the state of New Jersey on interview data are in Table 249. SUM~MARY The use study of the Manahawkin Bay - Little Egg Harbor system was an attempt to estimate the total man-days of the major estuarine activities; the total resource harvest of fishermen, shellfishermen, and hunters; and the total expenditures of the major activities occurring within the study area. Aerial surveys were designed to determine the numbers of persons engaged in the major activities of bank fishing, boat fishing, shellfishing, boating, sailing, water skiing, bathing, and hunting. These separate activities were also tabulated by eight geographical areas to better develop a total use picture of the study area. 7.64 During bag and creel surveys, data were obtained through personal inter- views to estimate the total resource harvest, as well as catch per effort fig- ures, for the major activity categories of bank fishing, boat fishing, shell- fishing, and hunting. Expenditure data were also obtained through personal interviews to estimate the total expense and per trip expense of the major activity categories. A residence survey was conducted to determine the county and/or state of residence of those persons participating in the estuarine related activities. This report presents the above estimates for two separate sampling periods. Initially, the use study of Manahawkin Bay - Little Egg Harbor was conducted from July 1973 to February 1974 (hereafter referred to as the first sampling period). The study was resumed in June 1974 and continued to May 1975 (the second sampling period). Estimates of total activity, resource harvest, and expenditures are presented for each sampling period. Activity estimates, catch per effort estimates, and per trip expenditure estimates were then compared for the two sampling periods. Aerial survey data show an increase of 16.27% in estimated man-days of ac- tivity from the first sampling period to the second. Yearly estimates of total man-days of activity are 203,672 man-days for June 1973 to May 1974 and 236,814 man-days for the time period, June 1974 to May 1975. The four major activity categories of bank fishing, boat fishing, boating, and shellfishi-ng showed in- creases in man-days of activity of 60%, 26%, 24% and 52% respectively, whereas, major decreases in use estimates occurred in the sailing and bathing categories. Bank fishing resource harvest estimates show an increase of 79% from the first sampling period to the second. The catch per effort increased from 3.00 to 3.35 fish (including crabs) per man-day, and the total bank fishing activity increased 60%. Boat fishing harvest comparisons show a decrease of 24% from the first sampling period to the second, due mostly to a reduction in the blue claw crab catch. Catch per effort estimates decreased from 6.47 to 3.90 fish (in- cluding crabs) per man-day. Hard clam harvest estimates decreased 9% when com- paring an equal number of man-days of activity. Over 19 x 106 clams were har- vested for the 10 month period, June 1974 to May 1975 excluding November and December 1974. An estimated total waterfowl harvest of 306 birds were recorded on the survey area during the 1973 hunting season with a hunter success ratio of 0.11 birds per hour. Bank fishermen's per trip expenditures increased from $5.27 to $7.33, boat fishermen from $10.44 to $15.21, shellfishermen from $5.18 to $6.23, sailors from $17.44 to $23.24, and bathers from $3.32 to $8.15, all due mostly to in- creased traveling costs. 7.65 REFERENCES American Fisheries Society. 1970.
