During Segment 2,
188 stations were sampled in Little Egg Harbor Bay from Manahawkin to Holgate.
Only the hard clam, Mercenaria mercenaria, was collected insignificant numbers.
The hard clam resource within the surveyed area of Little Egg Harbor Bay was estimated at 177.2 million clams.
Recruitment rates and size-frequency data indicate that the hard clam population of this region is dominated by a few larger, older year classes.
Biological investigations were performed for 40 prospective lease applications received for areas from Little Egg Harbor Bay in Ocean County to Great Sound in Cape May County.
Following a review of the biological reports submitted for these applications, the Atlantic Coast Shellfish Council approved all but seven of the applications.
The hard clam relay program continued to operate in Monmouth County.
The reported harvest for 1986 was 5,182,560 clams with a resultant catch per effort of 1307 clams/man/day.
These figures are virtually identical to those of 1985.
The Mullica River oyster beds were monitored for setting
- success, survival and overall bed condition.
The seed beds were in poor con-dition and had high mortality rates, with MSX infection being the likely reason for the observed decline in bed condition.

1 SHELLFISH INVENTORY The long term goal of the Shellfish Inventory project has been to determine the distribution and abundance of commercially valuable molluscan shellfish within New Jersey's coastal estuaries.
The last inventory of.New Jersey's estuarine shellfish resource was completed in 1963 and the information is seriously antiquated.
To provide the current data necessary to manage the State's estuarine.
shellfish resources, a comprehensive inventory was initiated in 1983 during the previous project (3-332-R).
During Segment 2 the shellfish inventory program concentrated its effort in Little Egg Harbor Bay..
As in the previous project, the sampling program was designed primarily to sample the hard clam, Mercenaria mercenaria, since this is the most abundant and widely distributed molluscan species within the estuaries along the Atlantic Coast of New Jersey.
The sampling procedure consists of towing a miniature hydraulic clam dredge (knife width of one foot) from a. 32 foot research vessel to collect adult shellfish.
The dredge is con-structed to collect all hard. clams 30 millimeters in length or. great-er.
Sampling efficiency for other shellfish species varies according
.to the size-of the organism.
Stations were established at approximately quarter mile intervals.
Stations were located by one or more methods including a three-point sextant fix, hand bearing compass reading or LORAN C coordinates.
After station position was established a buoy was placed overboard to insure the maintenance of the boat's position throughout sampling operations at each station.
Following deployment of the
- buoy, air
3 -
and water temperatures were recorded.
Water samples were collected for later analysis of dissolved oxygen,
- salinity, and pH.
Given the high sampling frequency and minimal variation of hydrographic data throughout Little Egg Harbor Bay water samples were collected at only the first and last station of each field day.
Dissolved oxygen was determined by Winkler titration.
Salinities were determined by a hand held refractometer and pH readings were obtained with a Taylor slide comparator.
Following collection of the water samples, one benthic sample was collected.by use of a Petersen dredge.
A portion of this sample was retained for later sediment analysis following procedures outlined in ASTM Standard D422-51 (modified).
Using the Wentworth grain size clas-sification, any sediment retained on a 2.0 millimeter sieve is con-sidered gravel and any sediment passing through a 63 micron sieve is classified as mud.
Results were expressed as percentages of gravel, sand and mud.
The sediment samples collected from Little Egg Harbor Bay await analysis.
The remainder of the sediment sample was washed through a 1.0 millimeter sieve and all material and organisms retain-ed on the sieve were preserved in 10% formalin.
These samples were then transferred to isopropyl (70%)
alcohol for later identification and enumeration of all benthic invertebrates.
Benthic invertebrates are currently awaiting sorting, identification and enumeration.
The water depth of the area was recorded and the tow line length determined utilizing a tow line length to depth ratio of 4:1.
In some situations in areas of deeper water the tow line length to depth ratio was reduced to 3:1.
In no instance, however, did this ratio fall below 3:1.
4 -
Two 100 foot tows were made, one on each side of the buoy, into the prevailing current.
The 100 foot distance was measured by paying out a marked line while towing the dredge.
In bottoms with a high percentage of clay, old oyster shell, or eel grass (Zostera marina),
it was not possible to tow the entire 100 feet because the dredge would become clogged.
Therefore, individual tows were shortened to 50 feet in this type of substrate.
At the end of the measured tow the vessel was held as stationary as possible until the dredge was raised off the bottom to prevent sampling more than the desired area.
The number of clams collected on each tow was recorded and the mean density determined by utilizing the average of the two tows.
Mean hard clams densities (other species also) are expressed in terms of number per square foot.
All hard clams and paired hard clam valves collected were meas-ured lengthwise to the nearest millimeter.
A size-frequency dis-tribution for Little Egg Harbor Bay was constructed using the pooled data from all 188 stations.
In all cases the hard clams collected were graded into the following size categories:
Seed (SL) 30-37 mm in length Littlenecks (LN) 38-55 mm in length Cherrystones (CS) 56-76 mm in length Chowders (CH)
> 76 mm.in length Natural hard clam mortality at each station was determined.
This mortality was based Upon the percentage of empty paired valves in the entire sample of paired valves and live clams.
Paired valves were also examined in an attempt to determine the cause of death.
5 -
Detailed results of clam density, water quality, size-frequency distribution and densities of associated benthic organisms can be found in Attachment A (Table 1).
A total of 188 stations were samp-led in Little Egg Harbor Bay from Manahawkin to Holgate.
Like most of New Jersey's estuarine areas, some areas in Little Egg Harbor Bay were too shallow to be sampled even at high water.
Charts showing stations locations are contained in Attachment A (Figure 1).
The hard clam was the only commercially important shellfish spe-cies collected within Little Egg Harbor Bay.
No soft clams (Mya arenaria),
bay scallops (Argopecten irradians), or oysters (Crassos-trea virginica) were collected and only three blue mussels (Mytilus edulis) were collected from the 188 stations sampled.
Figure 2 (Attachment A) depicts the distribution and abundance of hard clams in Little Egg Harbor Bay.
HARD CLAMS As previously mentioned, the sampling program was designed primar-ily to sample hard clam populations in a variety of substrate types.
The inventory program provided information not only on the distribu-tion and abundance of hard clams but also data on mortality, recruit-
- ment, and year class strength.
The hard clam was the most widely distributed shellfish species throughout Little Egg Harbor Bay.
For the purpose of delineating the general abundance patterns of the hard clam resource the three classifications of occurrence, moderate density, and high density were established and assigned density values of 0.01-0.19,. 0.20-0.49 and > 0.50 hard clams per square foot, respectively.
The density
6 -
categories selected resulted from a comparison of the densities ob-served during the sampling program and densities reported by other researchers.
In order to develop an estimate of the hard clam resource within a particular
- estuary, it is necessary to make some basic assumptions.
One assumption is that the dredge is 100% efficient.
Although we are confident that the dredge is relatively efficient, in actuality it is probably something less than 100% efficient.
Our estimate of the hard clam resource is therefore a conservative one.
The other assumption that we must take. into consideration is that the density observed at each station is representative of a much larger area than that sampled.
This may not be the case,
- however, as previous work by the Bureau of Shellfisheries and others has commonly shown hard clams to be rather gregarious, exhibiting a clustered distribution.
To minimize this source of estimation error, sampling frequency was increased to the maximum extent practicable.
Hard clam densities ranged from 0 to 2.62 clams per square foot.
For the purpose of calculating estimates of the hard clam resource the following density classifications were established:
Number of clams per square foot
.05
.06-.11
.12-.49
.5-
.99 1.0-1.99
> 2.0
7 -
Adjacent stations within the same density category listed above were grouped together and a mean density for that area determined by utilizing the hard clam density means of the individual stations.
A planimeter was utilized to estimate the size of the individual areas.
The mean density was then applied to the size of the area to yield the standing stock estimate for that particular area.
By summing the small areas a resource estimate of Little Egg Harbor Bay was developed.
The The hard clam resource was distributed over 16,372 acres within Little Egg Harbor Bay..
The estimated standing stock of hard clams in the sur-veyed area of Little Egg Harbor Bay is 177.2 million, clams.
YEAR CLASS STRENGTH To examine year class strength for Little Egg Harbor Bay, a single size-frequency distribution was constructed for the nearly 7000 clams measured from throughout the bay (Figure 3, Attachment A).
From this graph it is apparent that the hard clam population is dominated by a few larger, older year classes.
Individual hard clams collected by the dredge ranged in size from 20-106 mm with a mean size of 74.8 milli-meters.
The dominance of the population by a few older year classes supports the contention of area shellfishermen that the hard clam re-source in Little Egg Harbor has been declining, particularly in regard to the more desirable littleneck and cherrystone size categories.
RECRUITMENT Recruitment is defined as the percentage of clams entering the fishery at the legal size of 38 mm in length.
To determine, annual recruitment rates it was assumed that the seed collected between
8 -
30 and 37 mm represented a single year class and would thus be expected to be recruited into the fishery within the coming year.
For the purpose of this discussion, only those recruitment rates for moderate and high density areas. are considered since the re-cruitment rates for low density areas would be biased due to the small sample size.
The dominance of the Little Egg Harbor Bay hard clam population by a few older year classes, as exhibited in the size-frequency dis-tribution, was documented further by examination of recruitment rates for various: areas.
Recruitment rates ranged from 0.0 to 34.6 percent with anaverage of 3.92% for all moderate and high density areas.
This figure is well below the average recruitment rate of 5.7% for other areas inventoried since 1983.
Those areas with the highest recruitment rates occurred in the middle third of Little Egg Harbor Bay between threeand five miles north of Beach Haven Inlet.
Within this general area, however, there is no distinquishable pat-tern to the recruitment rates.
HARD CLAM MORTALITY Natural adult (>
30 mm) hard clam mortalities varied consider-ably from station to station.
The average total mortality for Little Egg Harbor Bay was 11.6 percent.
Of the total mortality figure 19.9%
was attributed to predation by horseshoe crabs (Limulus polyphemus),
17.4% due to predation by whelks (Busycon caraliculatum, B.
carica),
and 0.89% due to predation by the moon snail (Polinices duplicatus).
Observed abundance of the common clam predators such as:
- conchs, Busycon carica, and B. canaliculatum; moon snails, Polinices duplicatus
9 -
and Lunatia heros; oyster drills, Urosalpinx cinerea and Eupleura caudata; horseshoe crabs, Limulus polyphemus and starfish, A sterias forbesii was relatively low.
During Segment 3, sampling will be conducted in Great Bay and pro-ceed southward as time allows.
The inventory program is scheduled to continue sampling New Jersey estuaries that have not been recently in-ventoried until all estuaries have been completed and the distribution of the shellfish within these estuaries delineated.
Collection of the related data of recruitment and mortality rates, year class strength, sediment types and-associated benthic invertebrates will hopefully result in the development of management plans for the various species.

2 INVESTIGATION OF LEASE GROUND APPLICATIONS Commercial shellfishermen requiring areas of bay bottom for planting seed oysters and clams or as layout grounds submit lease applications to the Atlantic Coast Shellfish Council for their review.
Following this review process, the Council makes recom-mendations to the Commissioner of the Department of Environmental Protection whether the lease should be granted or remain open for public use.
The current philosophy of both the Atlantic Coast Shellfish Council and the New Jersey Bureau of Shellfisheries is to discourage-'leasing of productive habitat so that the resources of such areas remain available for public (commmercial and recrea-tional) utilization..
In order to assist the Council in their decision, each lease application is investigated for shellfish productivity with a biological report being submitted to each councilman prior to the monthly meeting of the Council.
The application is considered and discussed at the first meeting with the final decision being rendered at the meeting the following month.
The biological investigation of each lease application yields data on the present shellfish density of the area, year class strength and recruitment, mortality, associated organisms, sub-strate type and basic water quality (i.e.
dissolved oxygen, sal-
- inity, pH,
- depth, and temperature).
This information, in addit-ion to the history of the area, is used to determine the product-ivity of the area.
Each prospective lease is classified as productive, potentially
11 -
productive or nonproductive shellfish habitat depending on the re-sults of the biological investigation.
Productive habitat is de-fined as an area that is and/or has been a regular producer of var-ious shellfish species, although the classification is generally associated with hard and soft clams and oysters.
An area can be productive habitat for one speciesand nonproductive for another.
The Mullica River oyster seed beds, for example, are extremely productive oyster habitat but nonproductive with respect to hard clam habitat.
Areas are classified as nonproductive when there is no regular natural recruitment.
- However, many of these areas are excellent for growth making them favorable for aquacultural use.
Areas with biological data insufficient to classify them as productive or nonproductive are termed potentially productive.
During Segment 2, 58 applications were received for lease ground along the Atlantic Coast from Little Egg Harbor Bay to Great Sound.
Eighteen of the applications were canceled due to the applicants' noncompliance with the policy of the Atlantic Coast Shellfish Council requiring the staking of all lots within six months of the date of application.
Of the 40 applications for which biological investigations were performed, three were found to be productive, seven non-productive and 30 were classified as potentially productive.
Following a review of the biological reports submitted for these applications, the Atlantic Coast Shellfish Council approved all but seven of the applications.
The applications denied were either classified as productive or were sheltered areas that
12 -
were regularly worked during harsh winter weather.
The Council has a policy of denying lease applications in such areas so that they can remain available for public use.
Specific information regarding the location and results of the biological investigations for each lease can be found in Attachment B.

3 HARD CLAM RELAY MONITORING The relay program consists of transferring hard clams, Mercenaria mercenaria, from condemned areas onto leased lots in approved water.
Following a thirty day purification
- period, sam-ples are analyzed for bacterial contamination and if the analysis reveals the elimination of harmful bacteria the lots are opened for harvest.
Since the inception of the relay program in
- 1970, over 76 million clams have been utilized from condemned waters.
The intensive sampling program of the Inventory Program (Job
- 1) required that all available personnel devote most of their time to this activity.
Consequently,. relay monitoring was limited to the tabulation of harvest and catch per effort data obtained from the harvest receipts submitted by each relay participan~t.
During Segment 2,
the relay program continued in the waters of Raritan and Sandy Hook Bays as well as the Navesink, Shrewsbury, Manasquan and Shark Rivers in Monmouth County.
In addition, a lim-ited relay was conducted in Tuckerkton Creek and Cove in southern Ocean County.
Harvest and catch per effort data by area are includ-ed in Attachment B.
Table I (Attachment B) includes the relay summary data for 1986.
The 3965 man days of effort in 1986 yielded a total reported harvest for all relay areas of 5,182,560 clams.
The majority of shellfishing activity took place in the Navesink and Shrewsbury Rivers, where 2592 man-days of effort yielded a harvest of 3,564,975 clams (68.8% of the total relay harvest).
The mean catch per effort for all relay areas in 1986 was 1307 clams/man/day, which is virtually identical to the
14-1985 figure of 1316 clams/man/day.
Tuckerton Cove yielded the high-est catch per effort (1908 clams/man/day) although the harvest from this area (151,664 clams) was less than three percent of the total harvest.
The reported relay harvest for the first eight months of 1987, as shown in Table 2 (Attachment B),
was 3,109,170 clams-- a reduc-tion of nearly 11% over the harvest for the same period in 1986.
The Navesink and Shrewsbury Rivers continued to provide a majority (71.47%)
of the total harvest.
Sandy Hook Bay yielded the highest catch per effort (1603 clams/man/day) when the data is grouped by estuary.
The special opening of section 1OF within the Security Zone around the Earle Naval Pier contributed significantly tothe overall catch per effort figure for Sandy Hook Bay.
During the 106.18 man days of effort in Section 1OF, shellfishermen had an average catch per effort of 2271 clams/man/day and a total harvest of 241,185 clams.
The observed reduction in harvest is probably due to a combina-tion of factors, primarily decreased densities in some harvest areas and reduced by participation by shellfishermen choosing to work open areas rather than participate in the relay program.
The overall catch pereffort for all relay areas in 1987 was 1226 clams/man/day, a 6.2% reduction from the 1986 figure of 1307 clams/man/day..
In ad-dition to this
- factor, some shellfishermen have reduced their parti-cipation in the program since they have been able to "make a days pay" in approved waters of Oceanand Atlantic Counties.
This factor is reflected in the percentage of the total relay harvest which is planted in Tuckerton in southern Ocean County.
In
- 1986, 17.9% of
15 -
the total harvest was planted here.
For the first eight months of
- 1987, however, Tuckerton received only 4.4% of the total relay har-vest.
If the approved waters of Ocean and Atlantic Counties con-tinued to yield adequate harvests, it is likely that the decline in relay participation by individuals planting in Tuckerton will con-tinue into 1988.

4 OYSTER RESEARCH, INVENTORY, AND MANAGEMENT The management of the Mullica River oyster beds is conducted with the objective of providing market size oysters for harvest while at the same time ensuring that the seed beds are not exces-sively depleted.
To this
- end, the oyster beds were monitored to evaluate the oyster spawning season, seed oyster transplant pro-
- gram, bed condition, and oyster mortality.
The regular monitoring of the seed and market beds continued to determine setting
- success, mortality and overall bed condition.
Numerous one bushel samples of oyster and shell were collected from each bed.
Bed condition was evaluated in terms of the per-centage of oyster withineach sample.
Mortality was determined by calculating the percentage of gapers and boxes (paired valves) within a total sample of live oysters, gapers and boxes.
Year class structure was determined by dividing samples into the age categories of spat, yearlings, and older oysters.
The percentage of spat in each sample is an indication of the successful settle-ment and survival of young-of-the-year oysters.
The regular sampling of the seed beds revealed both French's Point and Moss Point beds to be in poor condition in comparison to data collected over the last ten years (Attachment D).
French's Point consisted of 45.2% oyster with a mean annual mortality of 26.5 percent.
Moss Point was composed of only 10.4% oyster and had a mean annual mortality of 62.1 percent.
These figures re-present a drastic change from the historical averages.
For ex-
- ample, during the period 1975-1985 French's Point and Moss Point
17-had average bed conditions of 83.8% and 75.8%,
respectively.
The bed condition of the Moss Point Bed -in 1986- (-1O-.4%-oyster) was- -
86.3% below the average bed condition for the period 1975-1985.
Both seed beds experienced an above average set in 1986.
The age composition of French's Point consisted of 21.2% spat with Moss Point consisting of 33.3% spat.
The Mullica River market beds, with infrequent natural set, greater disease and predation pressure, and periodic harvest, has shown a steady decline in bed condition since being planted during the transplant programs of 1979-1981.
Given the poor condition of these beds in 1985 (Fitney Bit Bed:
16.8% oyster; Reef Bed:
nearly 0% oyster) and the limited manpower of the Bu-reau, the market beds were not sampled in 1986.
Reports by shell-fishermen confirm the continuing decline of these beds.
In light of this, the market beds will not be opened to harvest during the 1987-1988 season.
The declining bed.condition, which has been observed for the last two years, is attributed to a great extent to infestation by the parasite Haplosporidium nelsoni (MSX) and to a lesser extent to the protistan parasite Perkinsus marinus ("Dermo").
Although in Segment 2 no oysters were sent to the Rutgers Oyster Research Laboratory in Bivalve, New Jersey for histological ex-amination, samples analyzed over the past five years have shown an increasing prevalence of these two parasites, corresponding to the decline in bed condition.
The extensive oyster mortalities experienced in the Mullica River estuary since. 1984 were compar-able to those experienced in Delaware Bay during the same period.
