The moratorium on   lease ground applications which was imposed during Segment 4 of the previous project     (3-332-R) continued during Segment 1.. Consequently,   only two lease ground investigations were performed. The moratorium has recently been lifted and the field work associated with this activity will proceed as time permits in Segment 2.
The last inventory of New Jersey's estuarine shellfish resource was completed in 1963 and the information is seriously antiquated.
The hard clam relay-program   continued to operate in Monmouth County. The reported harvest for Segment 1 was 5.7 million clams, an increase of approximately .47% over the previous segment.     The acquisition of an IBM pc has greatly improved the ability to moni-tor relay harvest from specific relay areas thereby facilitating improved resource management.
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).
The Mullica River oyster beds were monitored for setting success, survival and overall bed condition.     Both the seed and market beds were found to be in     comparatively poor condition.
During Segment 1 the shellfish inventory program concentrated its effort in Barnegat 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 construc-ted to collect all hard clams 30 millimeters in length or greater.Sampling efficiency for other shellfish species varies according to the size of the organism.Stations were established at half-mile intervals in upper Barnegat Bay as this region has historically been a poor hard clam producing area. In the southern half of Barnegat Bay stations were established at approximately quarter mile interevals.
Samples sent the Rutgers Oyster Research Laboratory in Bivalve, New Jersey for histological examination indicated that MSX infec-tion was a major contribution to the observed decline in bed con-dition.
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 and water temperatures were recorded.
JOB NO. 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.
Water samples were collected for later analysis of dissolved oxygen, salinity, and pH. Dissolved oxygen was determined by Winkler titration.
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.
Salinities were deter-mined by a hand held refractometer and pH readings were obtained with a Taylor slide comparator.
during the previous project     (3-332-R).
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 out-lined in ASTM Standard D422-51 (modified).

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 construc-ted to collect all hard clams 30 millimeters in       length or greater.
Using the Wentworth grain size classification, any sediment retained on a 2.0 millimeter sieve is considered gravel and any sediment passing through a 63 micron sieve is classified as mud. Results were expressed as percentages of gravel, sand and mud. Figure 3 (Attachment A) depicts sediment classifications for upper Barnegat Bay. Sediments for stations south of Toms River await analysis.
Sampling efficiency   for other shellfish species varies according to the size of the organism.
The remainder of the sediment sample was washed through a 1.0 millimeter sieve and all material and organisms retained 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.
Stations were established at half-mile intervals       in   upper Barnegat Bay as this region has historically been a poor hard clam producing area.

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..Two 100 foot tows were made, one on each side of the buoy, in-to 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 and old oyster shell it was not posssible to tow the entire 100 feet because the dredge would be-come clogged. .Therefore, individual tows were shortened to 50 feet in this type of substrate.

A size-frequency distribution was constructed at all stations where a sufficient number of clams were collected (at least 100 clams). In all cases the hard clams collected were graded into the following size categories:

Paired valves were also examined in     an attempt to determine the cause of death.
Like most of New Jersey's estuarine areas, many areas in Barnegat Bay were too shallow to be sampled even at high water. Charts showing station locations are contained in Attachment A (Figure 1)The commercially important shellfish species collected during the inventory of Barnegat Bay include the soft clam (Mya arenaria), blue mussel (Mytilus edulis) and the hard clam (M. mercenaria).

Since most of the soft clams and blue mussels were too small to be efficiently retained by the dredge, quantitative estimates for these specie.s were not performed. Charts delineating the distribution and abundance of hard and soft clams in Barnegat Bay are shown in Figure 2 (Attachment A).HARD CLAMS As previously mentioned, the sampling program was designed primarily to sample hard clam populations in a variety of sub-strate types. The inventory program provided information not only on the distribution and abundance of hard clams but also data on mortality, recruitment, and year class strength.The hard clam was the most widely distributed shellfish species throughout Barnegat 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.

blue mussel   (Mytilus edulis) and the hard clam   (M. mercenaria).
In order to develop an estimate of the hard clam resource within a particular estuary, it is necessary to make some basic assumptions.
Soft clams were collected in     siginificant quantities at only one station and these individuals collected were small in       size (X=31.5 mm). Blue mussels were collected at a number of stations in sparsequantities.     Since most of the soft clams and blue mussels were too small to be efficiently retained by the dredge, quantitative estimates for these specie.s were not performed.
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.
Charts delineating   the distribution and abundance of hard and soft clams in   Barnegat Bay are shown in Figure 2 (Attachment A).
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.
HARD CLAMS As previously mentioned,     the sampling program was designed primarily to sample hard clam populations       in a variety of sub-strate types. The inventory program provided information not only on the distribution and abundance of hard clams but also data on mortality,   recruitment,   and year class strength.
This source of estimation error was minimized to the maximum extent practicable by increa-sing sampling frequency in areas with moderate or high densities.
The hard clam was the most widely distributed shellfish species throughout Barnegat 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 categories selected resulted from a comparison of the densities observed during the sampling program and densities         reported by other researchers.
Hard clam densities ranged from 0 to 0.65 clams per square foot. For the purpose of calculating estimates of the hard clam resource the following density classifications were established:
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.
Number of clams per square foot< .05.06-.11.12-.49> .50 Adjacent stations with 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 Barnegat Bay*was developed.
Although we are confident that the dredge is       relatively efficient, in actuality it is probably something less than 100% efficient.
The hard clam resource was distributed over 22,185 acres within Barnegat Bay. The estimated standing stock of hard clams in the surveyed area of Barnegat Bay is 156 million clams. YEAR CLASS STRENGTH Due to the paucity of hard clams in much of Barnegat Bay, size-frequency distributions for the hard clam (M. mercenaria) were constructed for only seven of the 304 stations sampled (Figure 4, Attachment A) .Analysis of the size-frequency distri-bution for these stations where sufficient numbers of hard clams were collected indicates that only two to six year classes are represented~in many areas of Barnegat Bay. While a few younger year classes are represented, the general hard clam population in Barnegat Bay is dominated by a few large, older:year classes.Given the few number of clams measured and size-frequency distri-butions constructed, however, it is difficult to determine the actual year class strength in Barnegat Bay with any degree of validity.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 30 and 37 mm represented a single year class and would thus be expected to be recruited into the fishery within the*coming year.The dominance of the Barnegat Bay hard clam population by a few older year classes, as exhibited in the size-frequency dis-tributions, was documented further by examination of recruitment rates for various areas. Recruitment rates ranged from 0.0 to  11.1 percent with an average of 2.03% for all stations where hard clams were collected.
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
Those areas with the highest recruitment rates occurred in the lower third of Barnegat Bay within a few miles of Barnegat Inlet. Within this genera-l area, however, there is no distinguishable pattern 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 Barnegat Bay was 13.2 percent. Predation associated mortality of adult clams was insignificant in all areas sampled. Observed abundance of the common clam predators such as: conchs, Busycon carica, and B. canaliculatum; moon snails, Polinices duplicatus and Lunatia heros; oyster drills, .Urosalpinx cinerea and.Eupleura caudata; horseshoe crabs,- Limulus polyphemus and starfish, Asterias forbesii was relatively low.During Segment 2, sampling will be conducted in Little Egg Harbor Bay and proceed southward as time allows. The inventory program is scheduled to continue sampling New Jersey estuaries that have not been recently inventoried until all estuaries have been completed and the distribution of the shellfish within these estuaries delineated.
 
Collection of the related data of recruit-ment 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. INVENTORY OF ST. GEORGE'S THOROFARE St. George's Thorofare is a dead-end lagoon off Absecon Inlet on the southern end of Brigantine Island. Shellfish distribution charts compiled in 1963 rated St. George's Thorofare as having a high commercial value with respect to hard clams. Although being condemned for the direct market harvest of shellfish for over 30 years, St. George's Thorofare has been one of the designated har-vest sites of the Atlantic County Relay Program from 1979 to 1983.St. George's Thorofare was sampled via the sampling methods des-cribed previously.
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. This source of estimation error was minimized to the maximum extent practicable by increa-sing sampling frequency in   areas with moderate or high densities.
Stations were established so as to adequately cover all areas of this 133 acre water body. Sampling was conducted June 3-5, 1985, but due to time restrictions the survey results were not reported in the completion report for project 3-332-R. Twenty-two stations were sampled between Rum Point and the northerly end of the thorofare, an area of approximately 126 acres. The two lagoons on the south side of St. George's Thorofare were not sampled since these confined areas precluded vessel maneuverability.
Hard clam densities ranged from 0 to 0.65 clams per square foot. For the purpose of calculating estimates   of the hard clam resource the following density classifications were established:
Exact station locations are shown on Figure 5(Attachment A) .All field data, including depth, water quality analysis, sediment composition, clam density, and clam size, is listed by station in Table 2 of Attachment A.Distribution and Abundance The hard clam, M. mercenaria, was the most abundant and widely distributed molluscan species collected within St. George's Thorofare.
Number of clams per square foot
Based on the mean hard clam density, each station was classified as being an area of occurrence, moderate density, or high density as described previously.
                          < .05
Figure 6 (Attachment A) graphically presents.the distribution and abundance of hard clams according to the above classifications.
                        .06-.11
Hard clam densities ranged from 0.0-5.13 clams per square foot with an overall average of 0.97 clams per square foot. The hard clam resource within St. George's Thorofare, which was calculated via the procedure initially described in the inventory methods sec-tion, was estimated to be 6.2 million clams.Year Class Strength Size-frequency distributions for the hard clam were constructed for twelve of the twenty-two stations sampled and are presented in Figure 8 of Attachment A. Nine to thirteen year classes are repre-sented in St. George's Thorofare.
                        .12-.49
From review of the size frequency distributions it is apparent that this area has experienced success-ful spawning, setting, and survival on a fairly regular basis.Recruitment The average recruitment rate of St. George's Thorofare was de-.termined by the same procedure used for other inventoried areas.Recruitment rates ranged from 2.6 to 16.7 percent with a mean of 7.8 percent. Unlike most other areas inventoried, recruitment rates within St. George's Thorofare exhibited less variation be-tween stations, although this observation may be the result of greater sampling frequency.  ~Benthic Invertebrates Table 3 presents the densities of organisms collected by the hydraulic clam dredge. Thirteen species of benthic invertebrates were collected by the dredge, which, due to its design, collects benthic invertebrates at varying rates of collection efficiency.
                          > .50 Adjacent stations with 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.
Estimates of invertebrate density were calculated when possible.The hard clam was the most abundant and widely distributed species collected by the hydraulic dredge, occurring at 19 of the 22 sta-tions (86.4%) sampled. Razor clams (Ensis directus), blood arks (Anadara ovalis) , and pitar clams (Pitar morrhuanus) were the next most abundant species with the remaining species being distributed throughout St. George's Thorofare in reduced densities.
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.
Benthic samples were also collected with a Petersen bottom grab. However, in an effort to expedite the sorting and identi-fication of these samples, only molluscan intertebrates were iden-tified.Eight species of molluscan invertebrates were collected in 22 grab samples. The small bivalve Tellina sp. was the most abun-dant and widely distributed species occurring at 50% of all stations.As exhibited in Table 3, the remaining species were distributed throughout St. George's Thorofare.
By summing the small areas a resource estimate of Barnegat Bay
Juvenile hard clams were collected at four of the 22 stations sampled (stations 1, 2, 3, and 5). An estimated  
*was developed. The hard clam resource was distributed over 22,185 acres within Barnegat Bay. The estimated standing stock of hard clams in   the surveyed area of Barnegat Bay is 156 million clams.

YEAR CLASS STRENGTH Due to the paucity of hard clams in       much of Barnegat Bay, size-frequency distributions for the hard clam         (M. mercenaria) were constructed for only seven of the 304 stations sampled (Figure 4, Attachment A) . Analysis of the size-frequency       distri-bution for these stations where sufficient numbers of hard clams were collected indicates that only two to six year classes are represented~in many areas of Barnegat Bay.         While a few younger year classes are represented,     the general hard clam population in Barnegat Bay is dominated by a few large,     older:year classes.
Given the few number of clams measured and size-frequency distri-butions constructed,   however,   it   is difficult to determine the actual year class strength in     Barnegat Bay with any degree of validity.
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 30 and 37 mm represented a single year class and would thus be expected to be recruited into the fishery within the*
coming year.
The dominance of the Barnegat Bay hard clam population by a few older year classes,   as exhibited in     the size-frequency dis-tributions, was documented further by examination of recruitment rates for various areas. Recruitment rates ranged from 0.0 to

11.1 percent with an average of 2.03% for all stations where hard clams were collected. Those areas with the highest recruitment rates occurred in the lower third of Barnegat Bay within a few miles of Barnegat Inlet. Within this genera-l     area, however, there is no distinguishable pattern 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 Barnegat Bay was 13.2 percent.       Predation associated mortality of adult clams was insignificant in       all areas sampled.

St. George's Thorofare was sampled via the sampling methods des-cribed previously.       Stations were established so as to adequately cover all areas of this 133 acre water body.           Sampling was conducted June 3-5,   1985,   but due to time restrictions the survey results were not reported in     the completion report for project 3-332-R.       Twenty-two stations were sampled between Rum Point and the northerly end of the thorofare,     an area of approximately     126 acres. The two lagoons on the south side of St. George's Thorofare were not sampled since these confined areas precluded vessel maneuverability.             Exact station locations are shown on Figure 5(Attachment A) .           All field data, including depth,     water quality analysis,     sediment composition, clam density,   and clam size,   is   listed by station in   Table 2 of Attachment A.
Distribution and Abundance The hard clam,     M. mercenaria,     was the most abundant and widely distributed molluscan species collected within St. George's Thorofare.
Based on the mean hard clam density,         each station was classified as being an area of occurrence,     moderate density,     or high density as
 
described previously.     Figure 6 (Attachment A) graphically presents.
the distribution and abundance of hard clams according to the above classifications.
Hard clam densities ranged from 0.0-5.13     clams per square foot with an overall average of 0.97 clams per square foot.       The hard clam resource within St. George's Thorofare,   which was calculated via the procedure initially     described in   the inventory methods sec-tion, was estimated to be 6.2 million clams.
Year Class Strength Size-frequency distributions     for the hard clam were constructed for twelve of the twenty-two stations sampled and are presented in Figure 8 of Attachment A.     Nine to thirteen year classes are repre-sented in   St. George's Thorofare.     From review of the size frequency distributions it   is apparent that this area has experienced success-ful spawning,   setting,   and survival on a fairly regular basis.
Recruitment The average recruitment rate of St. George's Thorofare was de-.
termined by the same procedure used for other inventoried areas.
Recruitment   rates ranged from 2.6   to 16.7 percent with a mean of 7.8 percent. Unlike most other areas inventoried,     recruitment rates within St. George's Thorofare exhibited less variation be-tween stations,   although this observation may be the result of greater sampling frequency.

Benthic Invertebrates Table 3 presents the densities of organisms collected by the hydraulic clam dredge.         Thirteen species of benthic invertebrates were collected by the dredge,           which,   due to its design,   collects benthic invertebrates       at varying rates of collection efficiency.
Estimates of invertebrate         density were calculated when possible.
The hard clam was the most abundant and widely distributed species collected by the hydraulic dredge,           occurring at 19 of the 22 sta-tions   (86.4%) sampled.     Razor clams     (Ensis directus),   blood arks (Anadara ovalis) , and pitar clams         (Pitar morrhuanus)   were the next most abundant species with the remaining species being distributed throughout St. George's Thorofare           in   reduced densities.
Benthic samples were also collected with a Petersen bottom grab. However,   in an effort to expedite       the sorting and identi-fication of these samples,         only molluscan intertebrates were iden-tified.
Eight species of molluscan invertebrates were collected in 22 grab samples.       The small bivalve Tellina sp. was the most abun-dant and widely distributed species occurring at 50% of all stations.
As exhibited in     Table   3, the remaining species were distributed throughout St. George's Thorofare.
Juvenile hard clams were collected at four of the 22 stations sampled (stations 1, 2,       3, and 5). An estimated 1.8 million juve-nile hard clams      (i984 set) exist within the surveyed areas of stations 1, 2,    3,    and 5. These juveniles ranged in      size from 1.7 to 9.3 mm,  with this wide variation probably the result of multiple
 
spawnings    in 1984 as well as environmental    factors affecting. growth.
While juvenile hard clams are subject to great predation pressure following settlement,      their abundance at these stations up to one year later was a propitious finding of the resource survey.          The occurrence of    juveniles in  conjunction with theabundance of adult hard clams of many size classes is        a further indication of the vitality    of the resource within St. George's Thorofare.
Given that it is  still  under review by State personnel,  the report on the resource survey of St. George's Thorofare        is not in-cluded as an attachment to this publication.        However, tables and figures- presenting survey results are included in Attachment A.

INVENTORY OF LOWER DELAWARE BAY During the spring of 1986,          the Bureau of Shellfisheries was presented with the opportunity to extend its            shellfish inventory project into Delaware Bay.        The systematic inventory program, which was initiated in      Raritan and Sandy Hook Bays in      1983,  has proceeded southward completing stock assessments for all estuaries as far south as Manahawkin.        Because of this systematic approach, the Delaware Bay segment of the project would not have been initi-ated for several years had it        not been for the fortuitous interest of a couple of oyster companies in            determining the availability of commercial concentrations        of soft clams,    Mya arenaria,  and/or hard clams,  Mercenaria mercenaria,          in this bay. The interest of Mr. Robert Morgan of Port Norris Oyster Company and Mr.            Lee Robbins of Robbins Brothers,        Inc. provided th Bureau's personnel with a unique opportunity to develop a baseline survey for deter-mining a resource inventory in          the lower Dealawre Bay. Since these individuals were also interested in            utilizing available commercial gear,    i.e. an escalator dredge,      the Bureau was able to perform the survey without diverting equipment or essential personnel from its      established work schedule.        The vessel and operator were provided by these individuals,            while the Bureau provided logistical support and the personnel required for the survey.
AREA The area for this survey encompassed the lower Delaware Bay, from the Cape May Canal to the Southwest Line.              This area and
 
                                -  16 -
sampling stations are illustrated in Figure      9. Because most of this area has been leased for oyster cultivation        (Figure 10)  every attempt was made to select stations which did not infringe upon leased areas,  except for leases held by Mr. Morgan or Mr. Robbins.
Although it  was the intention of.the survey personnel      to establish the stations systematically,    a number of constraints      required alter-ations to the systematic approach.      These constraints    included:
operational  limitations of the harvesting gear and vessel,        bottom topography,  leased ground arrangements,    and the parochial interests of the individuals sponsoring this effort.        A sampling regime was developed to provide the most comprehensive information within the available  time frame. The survey effort was influenced to a large extent by the suggestive evidence,      yielded from oyster harvesting activities,    of potential concentrations      of clams.
An effort was made to establish transects      in    an offshore/inshore and upbay/downbay direction.
Certain areas were not included in    the sampling regime because of substrate composition. The New Jersey side of lower Delaware is  comprised of extensive,  shallow flats which are characterized by soft,  fluid muds. These areas exhibited very little      biological activity and by necessity were quickly discounted as sample sites.
Likewise,  areas which were composed of packed sand or a sand-peat combination had to be discounted.      These substrates proved difficult for the dredge to penetrate and as a result,        the dredge was grossly inefficient. This condition was found,    primarily,    along the shore-line adjacent to Cape May County    (Figure 10)  .
 
                                - 17  -
The dredge was the most efficient in    bottoms having a compo-sition of sand,  shell,  and mud; a loosely packed but somewhat stable bottom. This type of substrate was usually found adjoining leased areas,  so most of the sampling effort took place along the perimeter of the leased grounds.
METHODS As previously noted,    the vessel and harvesting gear for this segment of the Shellfish Inventory Project were furnished by Mr.
Morgan and Mr. Robbins. The vessel was an escalator dredge boat which was active in  the Chesapeake Bay soft clam fishery and leased for this survey. This vessel was selected because of the captain's experience with the soft clam fishery and the perception that fishery gear available  locally was inadequate to evaluate the commercial  status of the targeted species.
The dredge was an integrated unit operated hydraulically by the captain from the aft area of the vessel.      Angle of the dredge water pressure,  flow rate to the water manifold,    and speed of the conveyor system were conveniently controlled from this location. Materials collected were transported by the conveyor system past this control area for culling.      This arrangement provided for an operation that could be handled by a single individual under routine operating conditions.
The dredge used a 91 cm cutting bar with a water manifold and series of digging nozzles,    arranged approximately 25 to 30 cm above the cutting bar. Materials collected by the dredge were
 
                                -  18 -
moved along a 1.9 cm mesh conveyor system to the culling area.
Target species were removed from the conveyor,      counted,  and measured. Notation was made for associated    species collected.
Assessment of the bottom penetration by the dredge was based on the captain's experience  and the system's operating angle.      A penetration of 15 to 20 cm was thought to be typical.        The har-vesting efficiency was affected by water depth and declination of the dredging system to the bottom.      The maximum operating depth ranged from 15-18 feet. A critical operating angle was reached when the angle of declination began to exceed,        approxi-mately,  50 degrees. Beyond these limits,    the system failed to carry materials past the surface of the water.        The optimum opera-ting depth was 10 to 12 feet.
The sampling interval at each station was 10 minutes.        During this period all materials  collected were observed and pertinent information was recorded. Boxes were collected and used to provide a measure of recent mortality.      Salinity,  temperature,  and sediment samples were not taken during this phase of the project.
The position of each station was determined by using Del Norte Technology,  Inc.'s 520 DDMU Transponder system.      This horizon-tal positioning system utilizes frequencies      in the microwave range and provides an accuracy of + 1 m over an operating distance of 80 kms. The New Jersey Plane Coordinate System was the horizon-tal control data base for conversion of the distance measurements.
The location of each station was converted to a position of latitude-longitude,  using the formulas for computing geodetic position from Transverse Mercator coordinates.
 
The distance traveled during each sample interval was cal-culated by recording position information at the beginning and end of each station.      This datawas mathematically manipulated to provide the distance between end points.        These values were used to determine the area of coverage and the density of clams per square foot. The mean linear distance for these measurements was 657 feet. The range for the measurements was 172 to 1506 feet. Density values for clams were determined by dividing the number of clams harvested by the area covered during each sample interval. Because of the vagaries of the currents,    winds,  and the effect of the dredge on the course taken by the vessel,        the.
dredge path was usually sigmoidal      in shape. The density values, shown in  Attachment A (Table 4) , are,    therefore,  considered to be liberally skewed.      To obtain a more accurate perspective of the distance covered during each sampling effort,      a series of measurements was taken at 10 second intervals during several different tows. The mean value for these measurements was 1027 feet or nearly twice the mean linear distance computed from the distance measurements of the individual intervals.        This would imply that clam densities are considerably      lower than computed for the individual  stations.
All clams collected,    as well as paried valves,  were measured to the nearest millimeter.      A size frequency distribution was constructed for each station when a sufficient number of clams was collected  (N=100) . When an excessive number of clams was collected,  a subsample was used for the size frequency distribu-tion graph.. This situation occurred at only one station,      #44,
 
                                        -  20 -
when 323 clams were collected.              The subsample used for the size frequency  distribution        was 17.8. This  information is also included in Attachment A.
Hard  clams collected were graded            into size categories      accor-ding to their      relative      commercial    importance and are presented in Attachment A as a percentage            of  the total    collected. These categories    are as      follows:
Type                  Length(mm)
Seed                        30-37 Little Necks                38-55 Cherrystones                56-76 Chowders                      >76 RESULTS The objective of this project was to define and delineate the shellfish resource of lower Delaware Bay,                  in particular,    exploi-table concentrations of the hard clam,              Mercenaria mercenaria and the soft clam,      Mya arenaria.        For a. number of years,      dredging activities on leased oyster grounds have yielded small numbers of hard clams and some evidence of the occurrence of soft clams.
A study conducted by the University of Delaware had indicated that,  although hard clams did occur in            the Delaware Bay,      the re-source's potential for exploitation was marginal                  (Keck, 1974).
This report did not indicate            the presence of any soft clams in thebay. Shell material excavated from the bay bottom during this project contained soft clam valves indicating that the
 
                                -  21 species possibly did occur in      the region at one time.
A total of 49 stations-yielded    1515 hard clams. The abundance and distribution of hard clams found in      this survey can be found in Attachment A. In  previous reports,  McCloy and Joseph  (1984,    1985) had established three classifications for the relative abundance of hard clams. These classifications      are as follows:
Clams per square foot        Density Classification 0.01 -  0.19                  Low 0.20 - 0.49                    Moderate
                          >.50                  High These standards were established after evaluating survey results previously acquired under earlier phases of this project and the reported results of other researchers.
Assuming that these classifications have relative value to a commercial  fishery,  the hard clam resource of Delaware Bay appears to be insignificant. Density values ranged from 0.0017      to .422 clams per square foot.      Twenty-four stations had densities between 0.01-0.19  clams per square foot and would be considered        low density areas. Moderate densities were found at only two stations        (46 and 37),  while no station yielded sufficient quantities to attain a higher classification.      It should be remembered that these densi-ty values were based on the linear distance computed for each sample interval. The computed values are probably considerablyjhiqher than what actually occurs in    the bay.
 
                                  -  22 -
The number of clams,  mean,    and range measurements,          as well as mortality estimates,    are presented in Attachment A.              The mean size for the hard clam seems to increase in            both an inshore and upbay direction. Similar findings were reported in            the University of Delaware's  hard clam survey      (Keck,  1974). In addition to the relative low densities of clams found,          the available        resource appears to have very little    commercial value.          Ninety-two percent of the clams collected exceeded        the current market limit of 56mm for the valuable little    neck clam,    while 70.8% exceeded 76mm, the market limit for cherrystone clams.          Eight stations had a predominance of cherrystones      (56-76mm). For those stations where size frequency information was recorded,          thirty-four were dominated by chowder size clam,    length >76mm.        Seventy-three percent of the clams collected were taken at only 7 stations.                Size frequency distributions have been provided for these stations              in Figure 11.
The mean length of the clams taken was 83.2mm (s.d.              20.8mm).
AGE OF RESOURCE The results of this survey imply that the hard clam resource of lower Delaware Bay is relatively old, with very little    annual recruitment. A number of studies have been conducted over the years to determine the annual incremental          growth rate for the hard clam. Haskin  (1952-1954)    in Delaware Bay,      Haven & Loesch (1970)  in Chesapeake Bay,  and Fritz      (pers. comm. 1986)    seem to agree    that under normal growing conditions,          hard clams will attain a size of 60-70mm after 6 to 8 years.              Growth rates appar-ently slow considerably after this stage of development and
 
                                  -  23 -
thereafter  the annual  increment may only be a millimeter or two.
Several clams collected during this survey were aged by personnel at the Rutgers Shellfish Research Laboratory and found to have an estimated age in  excess of 40 years.        It    should be noted that these clams were  some of the larger ones collected.            According to the aging data available,      approximately 84% of the clams collected in  this survey probably were at least 8 years of age or older.
DISTRIBUTION OF RESOURCES The lack of sizeable hard clam resource            in Delaware Bay may be due to substrate composition.        Because bottom salinities are usually above .20 ppt in    the lower bay,      salinity is    not considered to be a limiting factor.      Several researchers        have reported that substrate appears  to be an influencing factor.            Keck (1974)  found that clam densities were highest in        areas with a composition of silt  and sand. Ropes and Martin (1960)        reported that the hard clam seems to prefer a substrate mixture of sand and mud.                Loesch
*and Haven (1972)  found that clam densities were lower in            soft, unstable bottom. The highest densities of clams were found in areas having a relatively stable bottom with a composition of sand,  shell,  mud or silt. This condition is        descriptive of those areas adjoining the leased oyster grounds            in  the bay. The most productive clam areas were,      in  fact,  situated along the periphery of leased grounds. A number of researchers have indicated that aggregrate materials    (shell,  gravel.,  etc.)    may deter predators, thus offering protection to small clams.            The accumulated    shell
 
deposits may offer the clams protection by making it        more difficult for predators to reach the burrowed clam.        Major clam predators in  the bay are:  the blue crab,    Callinectes sapidus; the horseshoe crab,  Limulus polyphemus;    xanthid crabs;  the whelks,  Busycon carica and B. canaliculatum;    the spider. crab,  Libinia emarginata;    and the snail,  Polinices duplicatus.      Limulus and Polinices were the most common predators collected.        Areas where mud  (Stations 14-21) or hard pack sands    (Stations 26-30)    occurred, clam density was either extremely low or no clams were collected.          Densities were usually higher,  as already noted,    in  aggregate bottom. The most productive stations were 32 through 39,        where shell material was in  abundance. The greatest number of predators was also found at these stations.
RECRUITMENT For purposes of this project,      McCloy and Joseph (1985)    have defined the recruitment class as being those clams between 30 and 37 mm in  length. It is  their supposition that these individ-uals comprise a single year class and would be expected to be re-cruited into the fishery within the coming year.          Haskin  (1952, 1954)  had previously indicated that the annual      growth for hard clams along the Cape May shoreline of Delaware Bay was approxi-mately 10-12 mm during their first        several years of development.
The definition is,  apparently,    applicable for this survey,    as clams in  the 30 to 37 mm range could be expected to enter the fishery within the same year.        Based upon the results of this survey,  the percentage of recruitment size clams available to the fishery was 0.9%. For comparison,      McCloy and Joseph  (1985)  found the
 
                              -  26  -
is a composition of shell,  sand,  and mud. There is sufficient evidence in  the literature to suggest that the composition of the bottom is  of significant importance to the survival rates of juvenile clams. Unfortunately,    most areas in lower Delawre Bay do not seem compatible for the development of commercially exploitable concentrations of hard. clams.

juve-nile hard clams (i984 set) exist within the surveyed areas of stations 1, 2, 3, and 5. These juveniles ranged in size from 1.7 to 9.3 mm, with this wide variation probably the result of multiple  spawnings in 1984 as well as environmental factors affecting.
average recruitment rates for the Manasquan and Shark Rivers to to be 11.9 and 4.8 percent,   respectively. All the recruitment size clams taken in   this survey were found at stations. 33,     34, 39, and 40. These stations are also those which yielded the lar-gest numbers of older clams.       This finding would further support previous works that.stated aggregate substrates       afforded the greatest protection from predators.
growth.While juvenile hard clams are subject to great predation pressure following settlement, their abundance at these stations up to one year later was a propitious finding of the resource survey. The occurrence of juveniles in conjunction with theabundance of adult hard clams of many size classes is a further indication of the vitality of the resource within St. George's Thorofare.
Hydrographic conditions in   the bay may also influence recruit-ment. The general counter clockwise circulation pattern in     the lower bay may disperse   larvae beyond the range of. the best setting areas. Juvenile clams setting in   areas without the aggregate substrates would become easy prey for the bottom foraging blue or horseshoe crabs,   which are in   abundance in the lower bay during certain times of the year. Loss of larvae from the system,     inade-quate :phytoplankton production,     and unstable bottom are also poten-tial   factors for the limited availability of recruitment size clams.
Given that it is still under review by State personnel, the report on the resource survey of St. George's Thorofare is not in-cluded as an attachment to this publication.
However, tables and figures- presenting survey results are included in Attachment A. INVENTORY OF LOWER DELAWARE BAY During the spring of 1986, the Bureau of Shellfisheries was presented with the opportunity to extend its shellfish inventory project into Delaware Bay. The systematic inventory program, which was initiated in Raritan and Sandy Hook Bays in 1983, has proceeded southward completing stock assessments for all estuaries as far south as Manahawkin.
Because of this systematic approach, the Delaware Bay segment of the project would not have been initi-ated for several years had it not been for the fortuitous interest of a couple of oyster companies in determining the availability of commercial concentrations of soft clams, Mya arenaria, and/or hard clams, Mercenaria mercenaria, in this bay. The interest of Mr. Robert Morgan of Port Norris Oyster Company and Mr. Lee Robbins of Robbins Brothers, Inc. provided th Bureau's personnel with a unique opportunity to develop a baseline survey for deter-mining a resource inventory in the lower Dealawre Bay. Since these individuals were also interested in utilizing available commercial gear, i.e. an escalator dredge, the Bureau was able to perform the survey without diverting equipment or essential personnel from its established work schedule.
The vessel and operator were provided by these individuals, while the Bureau provided logistical support and the personnel required for the survey.AREA The area for this survey encompassed the lower Delaware Bay, from the Cape May Canal to the Southwest Line. This area and sampling stations are illustrated in Figure 9. Because most of this area has been leased for oyster cultivation (Figure 10) every attempt was made to select stations which did not infringe upon leased areas, except for leases held by Mr. Morgan or Mr. Robbins.Although it was the intention of.the survey personnel to establish the stations systematically, a number of constraints required alter-ations to the systematic approach.
These constraints included: operational limitations of the harvesting gear and vessel, bottom topography, leased ground arrangements, and the parochial interests of the individuals sponsoring this effort. A sampling regime was developed to provide the most comprehensive information within the available time frame. The survey effort was influenced to a large extent by the suggestive evidence, yielded from oyster harvesting activities, of potential concentrations of clams.An effort was made to establish transects in an offshore/inshore and upbay/downbay direction.
Certain areas were not included in the sampling regime because of substrate composition.
The New Jersey side of lower Delaware is comprised of extensive, shallow flats which are characterized by soft, fluid muds. These areas exhibited very little biological activity and by necessity were quickly discounted as sample sites.Likewise, areas which were composed of packed sand or a sand-peat combination had to be discounted.

This type of substrate was usually found adjoining leased areas, so most of the sampling effort took place along the perimeter of the leased grounds.METHODS As previously noted, the vessel and harvesting gear for this segment of the Shellfish Inventory Project were furnished by Mr.Morgan and Mr. Robbins. The vessel was an escalator dredge boat which was active in the Chesapeake Bay soft clam fishery and leased for this survey. This vessel was selected because of the captain's experience with the soft clam fishery and the perception that fishery gear available locally was inadequate to evaluate the commercial status of the targeted species.The dredge was an integrated unit operated hydraulically by the captain from the aft area of the vessel.

The dredge used a 91 cm cutting bar with a water manifold and series of digging nozzles, arranged approximately 25 to 30 cm above the cutting bar. Materials collected by the dredge were  moved along a 1.9 cm mesh conveyor system to the culling area.Target species were removed from the conveyor, counted, and measured.
Notation was made for associated species collected.
Assessment of the bottom penetration by the dredge was based on the captain's experience and the system's operating angle. A penetration of 15 to 20 cm was thought to be typical. The har-vesting efficiency was affected by water depth and declination of the dredging system to the bottom. The maximum operating depth ranged from 15-18 feet. A critical operating angle was reached when the angle of declination began to exceed, approxi-mately, 50 degrees. Beyond these limits, the system failed to carry materials past the surface of the water. The optimum opera-ting depth was 10 to 12 feet.The sampling interval at each station was 10 minutes.

The mean linear distance for these measurements was 657 feet. The range for the measurements was 172 to 1506 feet. Density values for clams were determined by dividing the number of clams harvested by the area covered during each sample interval.
Because of the vagaries of the currents, winds, and the effect of the dredge on the course taken by the vessel, the.dredge path was usually sigmoidal in shape. The density values, shown in Attachment A (Table 4) , are, therefore, considered to be liberally skewed. To obtain a more accurate perspective of the distance covered during each sampling effort, a series of measurements was taken at 10 second intervals during several different tows.

This would imply that clam densities are considerably lower than computed for the individual stations.All clams collected, as well as paried valves, were measured to the nearest millimeter.

For a. number of years, dredging activities on leased oyster grounds have yielded small numbers of hard clams and some evidence of the occurrence of soft clams.A study conducted by the University of Delaware had indicated that, although hard clams did occur in the Delaware Bay, the re-source's potential for exploitation was marginal (Keck, 1974).This report did not indicate the presence of any soft clams in thebay. Shell material excavated from the bay bottom during this project contained soft clam valves indicating that the
-21 species possibly did occur in the region at one time.A total of 49 stations-yielded 1515 hard clams. The abundance and distribution of hard clams found in this survey can be found in Attachment A. In previous reports, McCloy and Joseph (1984, 1985)had established three classifications for the relative abundance of hard clams. These classifications are as follows: Clams per square foot Density Classification 0.01 -0.19 Low 0.20 -0.49 Moderate>.50 High These standards were established after evaluating survey results previously acquired under earlier phases of this project and the reported results of other researchers.
Assuming that these classifications have relative value to a commercial fishery, the hard clam resource of Delaware Bay appears to be insignificant.
Density values ranged from 0.0017 to .422 clams per square foot. Twenty-four stations had densities between 0.01-0.19 clams per square foot and would be considered low density areas. Moderate densities were found at only two stations (46 and 37), while no station yielded sufficient quantities to attain a higher classification.
It should be remembered that these densi-ty values were based on the linear distance computed for each sample interval.
The computed values are probably considerablyjhiqher than what actually occurs in the bay. The number of clams, mean, and range measurements, as well as mortality estimates, are presented in Attachment A. The mean size for the hard clam seems to increase in both an inshore and upbay direction.
Similar findings were reported in the University of Delaware's hard clam survey (Keck, 1974). In addition to the relative low densities of clams found, the available resource appears to have very little commercial value. Ninety-two percent of the clams collected exceeded the current market limit of 56mm for the valuable little neck clam, while 70.8% exceeded 76mm, the market limit for cherrystone clams. Eight stations had a predominance of cherrystones (56-76mm).
For those stations where size frequency information was recorded, thirty-four were dominated by chowder size clam, length >76mm. Seventy-three percent of the clams collected were taken at only 7 stations.
Size frequency distributions have been provided for these stations in Figure 11.The mean length of the clams taken was 83.2mm (s.d. 20.8mm).AGE OF RESOURCE The results of this survey imply that the hard clam resource of lower Delaware Bay is relatively old, with very little annual recruitment.
A number of studies have been conducted over the years to determine the annual incremental growth rate for the hard clam. Haskin (1952-1954) in Delaware Bay, Haven & Loesch (1970) in Chesapeake Bay, and Fritz (pers. comm. 1986) seem to agree that under normal growing conditions, hard clams will attain a size of 60-70mm after 6 to 8 years. Growth rates appar-ently slow considerably after this stage of development and  thereafter the annual increment may only be a millimeter or two.Several clams collected during this survey were aged by personnel at the Rutgers Shellfish Research Laboratory and found to have an estimated age in excess of 40 years. It should be noted that these clams were some of the larger ones collected.
According to the aging data available, approximately 84% of the clams collected in this survey probably were at least 8 years of age or older.DISTRIBUTION OF RESOURCES The lack of sizeable hard clam resource in Delaware Bay may be due to substrate composition.
Because bottom salinities are usually above .20 ppt in the lower bay, salinity is not considered to be a limiting factor. Several researchers have reported that substrate appears to be an influencing factor. Keck (1974) found that clam densities were highest in areas with a composition of silt and sand. Ropes and Martin (1960) reported that the hard clam seems to prefer a substrate mixture of sand and mud. Loesch*and Haven (1972) found that clam densities were lower in soft, unstable bottom. The highest densities of clams were found in areas having a relatively stable bottom with a composition of sand, shell, mud or silt. This condition is descriptive of those areas adjoining the leased oyster grounds in the bay. The most productive clam areas were, in fact, situated along the periphery of leased grounds. A number of researchers have indicated that aggregrate materials (shell, gravel., etc.) may deter predators, thus offering protection to small clams. The accumulated shell  deposits may offer the clams protection by making it more difficult for predators to reach the burrowed clam. Major clam predators in the bay are: the blue crab, Callinectes sapidus; the horseshoe crab, Limulus polyphemus; xanthid crabs; the whelks, Busycon carica and B. canaliculatum; the spider. crab, Libinia emarginata; and the snail, Polinices duplicatus.
Limulus and Polinices were the most common predators collected.
Areas where mud (Stations 14-21)or hard pack sands (Stations 26-30) occurred, clam density was either extremely low or no clams were collected.
Densities were usually higher, as already noted, in aggregate bottom. The most productive stations were 32 through 39, where shell material was in abundance.
The greatest number of predators was also found at these stations.RECRUITMENT For purposes of this project, McCloy and Joseph (1985) have defined the recruitment class as being those clams between 30 and 37 mm in length. It is their supposition that these individ-uals comprise a single year class and would be expected to be re-cruited into the fishery within the coming year. Haskin (1952, 1954) had previously indicated that the annual growth for hard clams along the Cape May shoreline of Delaware Bay was approxi-mately 10-12 mm during their first several years of development.
The definition is, apparently, applicable for this survey, as clams in the 30 to 37 mm range could be expected to enter the fishery within the same year. Based upon the results of this survey, the percentage of recruitment size clams available to the fishery was 0.9%. For comparison, McCloy and Joseph (1985) found the  is a composition of shell, sand, and mud. There is sufficient evidence in the literature to suggest that the composition of the bottom is of significant importance to the survival rates of juvenile clams. Unfortunately, most areas in lower Delawre Bay do not seem compatible for the development of commercially exploitable concentrations of hard. clams. average recruitment rates for the Manasquan and Shark Rivers to to be 11.9 and 4.8 percent, respectively.
All the recruitment size clams taken in this survey were found at stations.
33, 34, 39, and 40. These stations are also those which yielded the lar-gest numbers of older clams. This finding would further support previous works that.stated aggregate substrates afforded the greatest protection from predators.
Hydrographic conditions in the bay may also influence recruit-ment. The general counter clockwise circulation pattern in the lower bay may disperse larvae beyond the range of. the best setting areas. Juvenile clams setting in areas without the aggregate substrates would become easy prey for the bottom foraging blue or horseshoe crabs, which are in abundance in the lower bay during certain times of the year. Loss of larvae from the system, inade-quate :phytoplankton production, and unstable bottom are also poten-tial factors for the limited availability of recruitment size clams.

Following this review process, the Council makes recommenda-tions to the Commissioner of the Department of Environmental Protec-tion 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 (commercial and recreational) utiliza-tion.In order to assist the Council in their decision, each lease application is investigated for shellfish productivity with a bio-logical 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, salin-ity, pH, depth, and temperature).
 
This information, in addition to the history of the area, is. used to determine the productivity of the area.Each prospective lease is classified as productive, potentially  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 various shellfish species, although the classification is generally associatedwith hard and soft clams and oysters. An area can be productive habitat for one species and nonproductive for another.The Mullica River oyster seed beds, for example, are extremely pro-ductive oyster habitat but nonproductive with respect to hard clam habitat. Areas are classified as nonproductive when there is no regular natural recruitment.

This moratorium, which was announced during Segment IV of the previous project (3-332-R), remained in effect during Segment I of the current pro-ject.In light of the above, only two lease ground investigations were performed during Segment I. An investigation of the two lease-applications, both of which were located in Little Egg Harbor Bay, found them to be productive in terms of natural hard clam re-cruitment.
 
Following a review of the biological reports submitted for these lease applications, the Atlantic Coast Shellfish Council denied both leases so that these areas could remain available for public use. Seven other applications were cancelled 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.

Although originally scheduled to be lifted in the spring of 1986, the moratorium on lease applications was not lifteduntil October 1986.

JOB NO. 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 71 million clams have been utilized from condemned waters.The intensive sampling program of the Inventory Program (Job I) 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 participant.
The Mullica River oyster seed beds,     for example, are extremely pro-ductive 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.
During Segment I, 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. Harvest and catch per effort data by area are included in Attachment B.Table I (Attachment B) includes the relay summary data for 1985 as well as the first six months of 1986. Harvest data for specific relay harvest areas (i.e. 1-il, W, X, Y, Z) are not in-cluded for the 1985 data as staffing limitations prevented the extraction of that information from the relay harvest receipts.However, the recent acquisition of an IBM personal computer has greatly ameliorated this arduous task and has facilitated improved monitoring of harvest from specific relay areas. The continued use  of the IBM pc will improvethe management of the hard clam stocks associated with this program.The total reported harvest for all relay areas in 1985 was 5,144,862 clams. Those previously mentioned areas of northern Monmouth County (excluding the Manasquan and Shark Rivers) received the most activity with 3,646 man-days of effort and a resultant har-vest of 4,.855,254 clams (over 94% of the total 1985 relay harvest).The mean catch per effort for all relay areas in 1985 was 1316 clams/man/day, which is up 12.9% from the 1984 figure. It is un-known whether this increase is due to an actual increase in harvest or more accurate reporting by participating shellfishermen.
Areas with biological data insufficient to classify them as produc-tive or nonproductive are termed potentially productive.
The harvest data of the first six months of 1986, as shown on Table I (Attachment B), provides a more precise representation of the relay harvest. During this period, 1797 man-days of effort yielded a total reported harvest of 2,422,730 clams and a mean catch per effort of 1348 clams/man/day.
The intensive sampling program of Job I has involved the en-tire staff on a full time basis.,   greatly reducing the manpower available   to perform lease ground investigations.     This resulted in a backlog of lease applications which necessitated the implementa-tion of a moratorium on all   lease applications. This moratorium, which was announced during Segment IV of the previous project (3-332-R), remained in effect during Segment I of the current pro-ject.
Section 11 in Raritan Bay yielded the highest catch per effort (1,675 clams/man/day), but contributed only 22,343 clams to the total harvest for the first half of 1986.Shark River had the lowest catch per effort during this period (963 clams/man/day), although this figure is up approximately 19%from the Shark River catch per effort figures for 1984 and 1985.Relay totals for Segment I are up substantially from those of Segment V of the previous project (3-332-R)

The factors contributing to these in-creased figures are unknown, and speculation on the matter would be of little merit. JOB NO. 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.

denied both leases so that these areas could remain available for public use. Seven other applications were cancelled 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.
The regular monitoring of the seed and market beds continued to determine setting success, mortality and overall bedcondition.
Although originally scheduled to be lifted in     the spring of 1986, the moratorium on lease applications was not lifteduntil October 1986. It   may be necessary, however, to reinstate the moratorium since the staff of the Bureau of Shellfisheries     is more limited than in   previous years.
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 within each sampled. 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 relatively poor condition in comparison to 1984 figures. French's Point consisted of 65.8%oyster with a mean annual mortality of 34..6%. Moss Point data was nearly identical, being composed of 65.5% oyster with a mean annual mortality of 36.6 percent. In contrast, French's Point and Moss Point beds consisted of 85.3% and 94.8% oyster (respectively) in 1984 and had annual mortalities of three percent or less. Although  showing a decline in bed condition, both seed beds experienced a good set in 1985. The age composition of French's Point consisted of 59.9% spat with Moss Point consisting of 39.3% spat.The Mullica River market beds, with infrequent natural set, greater disease and predation pressure, and periodic harvest, con-tinued to exhibit a decline .in bed condition since being planted during the transplant programs of 1979-1981.
 
The annual sampling of the market beds indicated that the Fitney Bit bed was composed of only 16.8% oyster and had a total mortality of 46.1 percent.The Reef Bed consisted of virtually 100% shell as only nine live oysters were collected in nearly seven bushels of shell. The es-timated mortality was 52.6%, although the sample size was minimal.Samples of oysters collected from the seed and market beds were sent to the Rutgers Oyster Research Laboratory in Bivalve, New Jersey for histoligical examination.

Sample analysis confirmed that the parasite Haplospordium nelsoni (MSX) is at least partly responsible for the high mortalities observed on all beds. In addition, the protistan parasite Perknsus marinus ("Dermo")

ABSTRACT The inventory, program initiated in 1983 continued. During Segment 1, 304 stations were sampled in Barnegat Bay from Manto-loking to Manahawkin. Only the hard clam, Mercenaria mercenaria, was collected in significant numbers. The hard clam resource within the surveyed area of Barnegat Bay was estimated at 156 million clams. Inventories of St. George's Thorofare in Atlantic .County and Delaware Bay were also conducted. Charts delineating the distribution and abundance of the shellfish resources within these areas were prepared. The moratorium on lease ground applications which was imposed during Segment 4 of the previous project (3-332-R) continued during Segment 1.. Consequently, only two lease ground investigations were performed. The moratorium has recently been lifted and the field work associated with this activity will proceed as time permits in Segment 2. The hard clam relay-program continued to operate in Monmouth County. The reported harvest for Segment 1 was 5.7 million clams, an increase of approximately .47% over the previous segment. The acquisition of an IBM pc has greatly improved the ability to moni-tor relay harvest from specific relay areas thereby facilitating improved resource management. The Mullica River oyster beds were monitored for setting success, survival and overall bed condition. Both the seed and market beds were found to be in comparatively poor condition.

Samples sent the Rutgers Oyster Research Laboratory in Bivalve, New Jersey for histological examination indicated that MSX infec-tion was a major contribution to the observed decline in bed con-dition.

JOB NO. 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 1 the shellfish inventory program concentrated its effort in Barnegat 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 construc-ted to collect all hard clams 30 millimeters in length or greater. Sampling efficiency for other shellfish species varies according to the size of the organism. Stations were established at half-mile intervals in upper Barnegat Bay as this region has historically been a poor hard clam producing area. In the southern half of Barnegat Bay stations were established at approximately quarter mile interevals. Stations were located by one or more methods including a three point sextant fix, hand bearing compass reading or LORAN C coordinates. After 

                               -  4 -

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 and water temperatures were recorded. Water samples were collected for later analysis of dissolved oxygen, salinity, and pH. Dissolved oxygen was determined by Winkler titration. Salinities were deter-mined 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 out-lined in ASTM Standard D422-51 (modified). Using the Wentworth grain size classification, any sediment retained on a 2.0 millimeter sieve is considered gravel and any sediment passing through a 63 micron sieve is classified as mud. Results were expressed as percentages of gravel, sand and mud. Figure 3 (Attachment A) depicts sediment classifications for upper Barnegat Bay. Sediments for stations south of Toms River await analysis. The remainder of the sediment sample was washed through a 1.0 millimeter sieve and all material and organisms retained 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, identifica-tion 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.. Two 100 foot tows were made, one on each side of the buoy, in-to 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 and old oyster shell it was not posssible to tow the entire 100 feet because the dredge would be-come clogged. .Therefore, individual tows were shortened to 50 feet in this type of substrate. At the end of the measured tow the ves-sel 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 clam densites (other. species also) are expressed in terms of number per *square foot. All hard clams and paired hard clam valves collected were measured to the nearest millimeter. A size-frequency distribution was constructed at all stations where a sufficient number of clams were collected (at least 100 clams). 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

A size-frequency distribution was constructed for the single station (BB85-i) which contained commercial soft clam (Mya arenaria) densities. Since over 4600 soft clams were collected at this sta-tion, a subsample was measured to determine the size distribution of this population. 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. Detailed results of clam density, water quality, size-frequency. distributions and densities of associated benthic organisms can be found in Attachment A (Table 1). A total of 304 stations were sampled in Barne.gat Bay from Mantoloking to Manahawkin. Like most of New Jersey's estuarine areas, many areas in Barnegat Bay were too shallow to be sampled even at high water. Charts showing station locations are contained in Attachment A (Figure 1) The commercially important shellfish species collected during the inventory of Barnegat Bay include the soft clam (Mya arenaria), blue mussel (Mytilus edulis) and the hard clam (M. mercenaria). Soft clams were collected in siginificant quantities at only one station and these individuals collected were small in size (X=31.5 mm). Blue mussels were collected at a number of stations in sparsequantities. Since most of the soft clams and blue mussels were too small to be efficiently retained by the dredge, quantitative estimates for these specie.s were not performed.

Charts delineating the distribution and abundance of hard and soft clams in Barnegat Bay are shown in Figure 2 (Attachment A). HARD CLAMS As previously mentioned, the sampling program was designed primarily to sample hard clam populations in a variety of sub-strate types. The inventory program provided information not only on the distribution and abundance of hard clams but also data on mortality, recruitment, and year class strength. The hard clam was the most widely distributed shellfish species throughout Barnegat 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 categories selected resulted from a comparison of the densities observed 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. This source of estimation error was minimized to the maximum extent practicable by increa-sing sampling frequency in areas with moderate or high densities. Hard clam densities ranged from 0 to 0.65 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
                         > .50 Adjacent stations with 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 Barnegat Bay

  • was developed. The hard clam resource was distributed over 22,185 acres within Barnegat Bay. The estimated standing stock of hard clams in the surveyed area of Barnegat Bay is 156 million clams.

YEAR CLASS STRENGTH Due to the paucity of hard clams in much of Barnegat Bay, size-frequency distributions for the hard clam (M. mercenaria) were constructed for only seven of the 304 stations sampled (Figure 4, Attachment A) . Analysis of the size-frequency distri-bution for these stations where sufficient numbers of hard clams were collected indicates that only two to six year classes are represented~in many areas of Barnegat Bay. While a few younger year classes are represented, the general hard clam population in Barnegat Bay is dominated by a few large, older:year classes. Given the few number of clams measured and size-frequency distri-butions constructed, however, it is difficult to determine the actual year class strength in Barnegat Bay with any degree of validity. 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 30 and 37 mm represented a single year class and would thus be expected to be recruited into the fishery within the* coming year. The dominance of the Barnegat Bay hard clam population by a few older year classes, as exhibited in the size-frequency dis-tributions, was documented further by examination of recruitment rates for various areas. Recruitment rates ranged from 0.0 to 

                                -  10  -

11.1 percent with an average of 2.03% for all stations where hard clams were collected. Those areas with the highest recruitment rates occurred in the lower third of Barnegat Bay within a few miles of Barnegat Inlet. Within this genera-l area, however, there is no distinguishable pattern 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 Barnegat Bay was 13.2 percent. Predation associated mortality of adult clams was insignificant in all areas sampled. Observed abundance of the common clam predators such as: conchs, Busycon carica, and B. canaliculatum; moon snails, Polinices duplicatus and Lunatia heros; oyster drills, .Urosalpinx cinerea and.Eupleura caudata; horseshoe crabs,- Limulus polyphemus and starfish, Asterias forbesii was relatively low. During Segment 2, sampling will be conducted in Little Egg Harbor Bay and proceed southward as time allows. The inventory program is scheduled to continue sampling New Jersey estuaries that have not been recently inventoried until all estuaries have been completed and the distribution of the shellfish within these estuaries delineated. Collection of the related data of recruit-ment 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.

INVENTORY OF ST. GEORGE'S THOROFARE St. George's Thorofare is a dead-end lagoon off Absecon Inlet on the southern end of Brigantine Island. Shellfish distribution charts compiled in 1963 rated St. George's Thorofare as having a high commercial value with respect to hard clams. Although being condemned for the direct market harvest of shellfish for over 30 years, St. George's Thorofare has been one of the designated har-vest sites of the Atlantic County Relay Program from 1979 to 1983. St. George's Thorofare was sampled via the sampling methods des-cribed previously. Stations were established so as to adequately cover all areas of this 133 acre water body. Sampling was conducted June 3-5, 1985, but due to time restrictions the survey results were not reported in the completion report for project 3-332-R. Twenty-two stations were sampled between Rum Point and the northerly end of the thorofare, an area of approximately 126 acres. The two lagoons on the south side of St. George's Thorofare were not sampled since these confined areas precluded vessel maneuverability. Exact station locations are shown on Figure 5(Attachment A) . All field data, including depth, water quality analysis, sediment composition, clam density, and clam size, is listed by station in Table 2 of Attachment A. Distribution and Abundance The hard clam, M. mercenaria, was the most abundant and widely distributed molluscan species collected within St. George's Thorofare. Based on the mean hard clam density, each station was classified as being an area of occurrence, moderate density, or high density as

described previously. Figure 6 (Attachment A) graphically presents. the distribution and abundance of hard clams according to the above classifications. Hard clam densities ranged from 0.0-5.13 clams per square foot with an overall average of 0.97 clams per square foot. The hard clam resource within St. George's Thorofare, which was calculated via the procedure initially described in the inventory methods sec-tion, was estimated to be 6.2 million clams. Year Class Strength Size-frequency distributions for the hard clam were constructed for twelve of the twenty-two stations sampled and are presented in Figure 8 of Attachment A. Nine to thirteen year classes are repre-sented in St. George's Thorofare. From review of the size frequency distributions it is apparent that this area has experienced success-ful spawning, setting, and survival on a fairly regular basis. Recruitment The average recruitment rate of St. George's Thorofare was de-. termined by the same procedure used for other inventoried areas. Recruitment rates ranged from 2.6 to 16.7 percent with a mean of 7.8 percent. Unlike most other areas inventoried, recruitment rates within St. George's Thorofare exhibited less variation be-tween stations, although this observation may be the result of greater sampling frequency.

Benthic Invertebrates Table 3 presents the densities of organisms collected by the hydraulic clam dredge. Thirteen species of benthic invertebrates were collected by the dredge, which, due to its design, collects benthic invertebrates at varying rates of collection efficiency. Estimates of invertebrate density were calculated when possible. The hard clam was the most abundant and widely distributed species collected by the hydraulic dredge, occurring at 19 of the 22 sta-tions (86.4%) sampled. Razor clams (Ensis directus), blood arks (Anadara ovalis) , and pitar clams (Pitar morrhuanus) were the next most abundant species with the remaining species being distributed throughout St. George's Thorofare in reduced densities. Benthic samples were also collected with a Petersen bottom grab. However, in an effort to expedite the sorting and identi-fication of these samples, only molluscan intertebrates were iden-tified. Eight species of molluscan invertebrates were collected in 22 grab samples. The small bivalve Tellina sp. was the most abun-dant and widely distributed species occurring at 50% of all stations. As exhibited in Table 3, the remaining species were distributed throughout St. George's Thorofare. Juvenile hard clams were collected at four of the 22 stations sampled (stations 1, 2, 3, and 5). An estimated 1.8 million juve-nile hard clams (i984 set) exist within the surveyed areas of stations 1, 2, 3, and 5. These juveniles ranged in size from 1.7 to 9.3 mm, with this wide variation probably the result of multiple

spawnings in 1984 as well as environmental factors affecting. growth. While juvenile hard clams are subject to great predation pressure following settlement, their abundance at these stations up to one year later was a propitious finding of the resource survey. The occurrence of juveniles in conjunction with theabundance of adult hard clams of many size classes is a further indication of the vitality of the resource within St. George's Thorofare. Given that it is still under review by State personnel, the report on the resource survey of St. George's Thorofare is not in-cluded as an attachment to this publication. However, tables and figures- presenting survey results are included in Attachment A.

INVENTORY OF LOWER DELAWARE BAY During the spring of 1986, the Bureau of Shellfisheries was presented with the opportunity to extend its shellfish inventory project into Delaware Bay. The systematic inventory program, which was initiated in Raritan and Sandy Hook Bays in 1983, has proceeded southward completing stock assessments for all estuaries as far south as Manahawkin. Because of this systematic approach, the Delaware Bay segment of the project would not have been initi-ated for several years had it not been for the fortuitous interest of a couple of oyster companies in determining the availability of commercial concentrations of soft clams, Mya arenaria, and/or hard clams, Mercenaria mercenaria, in this bay. The interest of Mr. Robert Morgan of Port Norris Oyster Company and Mr. Lee Robbins of Robbins Brothers, Inc. provided th Bureau's personnel with a unique opportunity to develop a baseline survey for deter-mining a resource inventory in the lower Dealawre Bay. Since these individuals were also interested in utilizing available commercial gear, i.e. an escalator dredge, the Bureau was able to perform the survey without diverting equipment or essential personnel from its established work schedule. The vessel and operator were provided by these individuals, while the Bureau provided logistical support and the personnel required for the survey. AREA The area for this survey encompassed the lower Delaware Bay, from the Cape May Canal to the Southwest Line. This area and 

                               -  16 -

sampling stations are illustrated in Figure 9. Because most of this area has been leased for oyster cultivation (Figure 10) every attempt was made to select stations which did not infringe upon leased areas, except for leases held by Mr. Morgan or Mr. Robbins. Although it was the intention of.the survey personnel to establish the stations systematically, a number of constraints required alter-ations to the systematic approach. These constraints included: operational limitations of the harvesting gear and vessel, bottom topography, leased ground arrangements, and the parochial interests of the individuals sponsoring this effort. A sampling regime was developed to provide the most comprehensive information within the available time frame. The survey effort was influenced to a large extent by the suggestive evidence, yielded from oyster harvesting activities, of potential concentrations of clams. An effort was made to establish transects in an offshore/inshore and upbay/downbay direction. Certain areas were not included in the sampling regime because of substrate composition. The New Jersey side of lower Delaware is comprised of extensive, shallow flats which are characterized by soft, fluid muds. These areas exhibited very little biological activity and by necessity were quickly discounted as sample sites. Likewise, areas which were composed of packed sand or a sand-peat combination had to be discounted. These substrates proved difficult for the dredge to penetrate and as a result, the dredge was grossly inefficient. This condition was found, primarily, along the shore-line adjacent to Cape May County (Figure 10) . 

                                - 17  -

The dredge was the most efficient in bottoms having a compo-sition of sand, shell, and mud; a loosely packed but somewhat stable bottom. This type of substrate was usually found adjoining leased areas, so most of the sampling effort took place along the perimeter of the leased grounds. METHODS As previously noted, the vessel and harvesting gear for this segment of the Shellfish Inventory Project were furnished by Mr. Morgan and Mr. Robbins. The vessel was an escalator dredge boat which was active in the Chesapeake Bay soft clam fishery and leased for this survey. This vessel was selected because of the captain's experience with the soft clam fishery and the perception that fishery gear available locally was inadequate to evaluate the commercial status of the targeted species. The dredge was an integrated unit operated hydraulically by the captain from the aft area of the vessel. Angle of the dredge water pressure, flow rate to the water manifold, and speed of the conveyor system were conveniently controlled from this location. Materials collected were transported by the conveyor system past this control area for culling. This arrangement provided for an operation that could be handled by a single individual under routine operating conditions. The dredge used a 91 cm cutting bar with a water manifold and series of digging nozzles, arranged approximately 25 to 30 cm above the cutting bar. Materials collected by the dredge were 

                               -  18 -

moved along a 1.9 cm mesh conveyor system to the culling area. Target species were removed from the conveyor, counted, and measured. Notation was made for associated species collected. Assessment of the bottom penetration by the dredge was based on the captain's experience and the system's operating angle. A penetration of 15 to 20 cm was thought to be typical. The har-vesting efficiency was affected by water depth and declination of the dredging system to the bottom. The maximum operating depth ranged from 15-18 feet. A critical operating angle was reached when the angle of declination began to exceed, approxi-mately, 50 degrees. Beyond these limits, the system failed to carry materials past the surface of the water. The optimum opera-ting depth was 10 to 12 feet. The sampling interval at each station was 10 minutes. During this period all materials collected were observed and pertinent information was recorded. Boxes were collected and used to provide a measure of recent mortality. Salinity, temperature, and sediment samples were not taken during this phase of the project. The position of each station was determined by using Del Norte Technology, Inc.'s 520 DDMU Transponder system. This horizon-tal positioning system utilizes frequencies in the microwave range and provides an accuracy of + 1 m over an operating distance of 80 kms. The New Jersey Plane Coordinate System was the horizon-tal control data base for conversion of the distance measurements. The location of each station was converted to a position of latitude-longitude, using the formulas for computing geodetic position from Transverse Mercator coordinates.

The distance traveled during each sample interval was cal-culated by recording position information at the beginning and end of each station. This datawas mathematically manipulated to provide the distance between end points. These values were used to determine the area of coverage and the density of clams per square foot. The mean linear distance for these measurements was 657 feet. The range for the measurements was 172 to 1506 feet. Density values for clams were determined by dividing the number of clams harvested by the area covered during each sample interval. Because of the vagaries of the currents, winds, and the effect of the dredge on the course taken by the vessel, the. dredge path was usually sigmoidal in shape. The density values, shown in Attachment A (Table 4) , are, therefore, considered to be liberally skewed. To obtain a more accurate perspective of the distance covered during each sampling effort, a series of measurements was taken at 10 second intervals during several different tows. The mean value for these measurements was 1027 feet or nearly twice the mean linear distance computed from the distance measurements of the individual intervals. This would imply that clam densities are considerably lower than computed for the individual stations. All clams collected, as well as paried valves, were measured to the nearest millimeter. A size frequency distribution was constructed for each station when a sufficient number of clams was collected (N=100) . When an excessive number of clams was collected, a subsample was used for the size frequency distribu-tion graph.. This situation occurred at only one station, #44, 

                                       -  20 -

when 323 clams were collected. The subsample used for the size frequency distribution was 17.8. This information is also included in Attachment A. Hard clams collected were graded into size categories accor-ding to their relative commercial importance and are presented in Attachment A as a percentage of the total collected. These categories are as follows: Type Length(mm) Seed 30-37 Little Necks 38-55 Cherrystones 56-76 Chowders >76 RESULTS The objective of this project was to define and delineate the shellfish resource of lower Delaware Bay, in particular, exploi-table concentrations of the hard clam, Mercenaria mercenaria and the soft clam, Mya arenaria. For a. number of years, dredging activities on leased oyster grounds have yielded small numbers of hard clams and some evidence of the occurrence of soft clams. A study conducted by the University of Delaware had indicated that, although hard clams did occur in the Delaware Bay, the re-source's potential for exploitation was marginal (Keck, 1974). This report did not indicate the presence of any soft clams in thebay. Shell material excavated from the bay bottom during this project contained soft clam valves indicating that the 

                                -   21 species possibly did occur in      the region at one time.

A total of 49 stations-yielded 1515 hard clams. The abundance and distribution of hard clams found in this survey can be found in Attachment A. In previous reports, McCloy and Joseph (1984, 1985) had established three classifications for the relative abundance of hard clams. These classifications are as follows: Clams per square foot Density Classification 0.01 - 0.19 Low 0.20 - 0.49 Moderate 

                          >.50                  High These standards were established after evaluating survey results previously acquired under earlier phases of this project and the reported results of other researchers.

Assuming that these classifications have relative value to a commercial fishery, the hard clam resource of Delaware Bay appears to be insignificant. Density values ranged from 0.0017 to .422 clams per square foot. Twenty-four stations had densities between 0.01-0.19 clams per square foot and would be considered low density areas. Moderate densities were found at only two stations (46 and 37), while no station yielded sufficient quantities to attain a higher classification. It should be remembered that these densi-ty values were based on the linear distance computed for each sample interval. The computed values are probably considerablyjhiqher than what actually occurs in the bay. 

                                 -  22 -

The number of clams, mean, and range measurements, as well as mortality estimates, are presented in Attachment A. The mean size for the hard clam seems to increase in both an inshore and upbay direction. Similar findings were reported in the University of Delaware's hard clam survey (Keck, 1974). In addition to the relative low densities of clams found, the available resource appears to have very little commercial value. Ninety-two percent of the clams collected exceeded the current market limit of 56mm for the valuable little neck clam, while 70.8% exceeded 76mm, the market limit for cherrystone clams. Eight stations had a predominance of cherrystones (56-76mm). For those stations where size frequency information was recorded, thirty-four were dominated by chowder size clam, length >76mm. Seventy-three percent of the clams collected were taken at only 7 stations. Size frequency distributions have been provided for these stations in Figure 11. The mean length of the clams taken was 83.2mm (s.d. 20.8mm). AGE OF RESOURCE The results of this survey imply that the hard clam resource of lower Delaware Bay is relatively old, with very little annual recruitment. A number of studies have been conducted over the years to determine the annual incremental growth rate for the hard clam. Haskin (1952-1954) in Delaware Bay, Haven & Loesch (1970) in Chesapeake Bay, and Fritz (pers. comm. 1986) seem to agree that under normal growing conditions, hard clams will attain a size of 60-70mm after 6 to 8 years. Growth rates appar-ently slow considerably after this stage of development and 

                                  -  23 -

thereafter the annual increment may only be a millimeter or two. Several clams collected during this survey were aged by personnel at the Rutgers Shellfish Research Laboratory and found to have an estimated age in excess of 40 years. It should be noted that these clams were some of the larger ones collected. According to the aging data available, approximately 84% of the clams collected in this survey probably were at least 8 years of age or older. DISTRIBUTION OF RESOURCES The lack of sizeable hard clam resource in Delaware Bay may be due to substrate composition. Because bottom salinities are usually above .20 ppt in the lower bay, salinity is not considered to be a limiting factor. Several researchers have reported that substrate appears to be an influencing factor. Keck (1974) found that clam densities were highest in areas with a composition of silt and sand. Ropes and Martin (1960) reported that the hard clam seems to prefer a substrate mixture of sand and mud. Loesch

  • and Haven (1972) found that clam densities were lower in soft, unstable bottom. The highest densities of clams were found in areas having a relatively stable bottom with a composition of sand, shell, mud or silt. This condition is descriptive of those areas adjoining the leased oyster grounds in the bay. The most productive clam areas were, in fact, situated along the periphery of leased grounds. A number of researchers have indicated that aggregrate materials (shell, gravel., etc.) may deter predators, thus offering protection to small clams. The accumulated shell

deposits may offer the clams protection by making it more difficult for predators to reach the burrowed clam. Major clam predators in the bay are: the blue crab, Callinectes sapidus; the horseshoe crab, Limulus polyphemus; xanthid crabs; the whelks, Busycon carica and B. canaliculatum; the spider. crab, Libinia emarginata; and the snail, Polinices duplicatus. Limulus and Polinices were the most common predators collected. Areas where mud (Stations 14-21) or hard pack sands (Stations 26-30) occurred, clam density was either extremely low or no clams were collected. Densities were usually higher, as already noted, in aggregate bottom. The most productive stations were 32 through 39, where shell material was in abundance. The greatest number of predators was also found at these stations. RECRUITMENT For purposes of this project, McCloy and Joseph (1985) have defined the recruitment class as being those clams between 30 and 37 mm in length. It is their supposition that these individ-uals comprise a single year class and would be expected to be re-cruited into the fishery within the coming year. Haskin (1952, 1954) had previously indicated that the annual growth for hard clams along the Cape May shoreline of Delaware Bay was approxi-mately 10-12 mm during their first several years of development. The definition is, apparently, applicable for this survey, as clams in the 30 to 37 mm range could be expected to enter the fishery within the same year. Based upon the results of this survey, the percentage of recruitment size clams available to the fishery was 0.9%. For comparison, McCloy and Joseph (1985) found the 

                             -  26  -

is a composition of shell, sand, and mud. There is sufficient evidence in the literature to suggest that the composition of the bottom is of significant importance to the survival rates of juvenile clams. Unfortunately, most areas in lower Delawre Bay do not seem compatible for the development of commercially exploitable concentrations of hard. clams. 

                                -  25 -

average recruitment rates for the Manasquan and Shark Rivers to to be 11.9 and 4.8 percent, respectively. All the recruitment size clams taken in this survey were found at stations. 33, 34, 39, and 40. These stations are also those which yielded the lar-gest numbers of older clams. This finding would further support previous works that.stated aggregate substrates afforded the greatest protection from predators. Hydrographic conditions in the bay may also influence recruit-ment. The general counter clockwise circulation pattern in the lower bay may disperse larvae beyond the range of. the best setting areas. Juvenile clams setting in areas without the aggregate substrates would become easy prey for the bottom foraging blue or horseshoe crabs, which are in abundance in the lower bay during certain times of the year. Loss of larvae from the system, inade-quate :phytoplankton production, and unstable bottom are also poten-tial factors for the limited availability of recruitment size clams.

SUMMARY

This survey'has supported data collected during previous surveys that indicated the existence of only marginal populations of hard clams in Delaware Bay. Although valves of the soft clam, Mya arenaria, were collected, there was no evidence to suggest that this species occurs in the bay. The available hard clam resource appears to be relatively old, with limited annual re-cruitment. Most of the resource was found in areas adjacent to producing or formerly producing oyster bottom where the substrate

JOB NO. 2 INVESTIGATION OF LEASE 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 re-view. Following this review process, the Council makes recommenda-tions to the Commissioner of the Department of Environmental Protec-tion 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 (commercial and recreational) utiliza-tion. In order to assist the Council in their decision, each lease application is investigated for shellfish productivity with a bio-logical 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, salin-ity, pH, depth, and temperature). This information, in addition to the history of the area, is. used to determine the productivity of the area. Each prospective lease is classified as productive, potentially 

                                -  28 -

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 various shellfish species, although the classification is generally associatedwith hard and soft clams and oysters. An area can be productive habitat for one species and nonproductive for another. The Mullica River oyster seed beds, for example, are extremely pro-ductive 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 produc-tive or nonproductive are termed potentially productive. The intensive sampling program of Job I has involved the en-tire staff on a full time basis., greatly reducing the manpower available to perform lease ground investigations. This resulted in a backlog of lease applications which necessitated the implementa-tion of a moratorium on all lease applications. This moratorium, which was announced during Segment IV of the previous project (3-332-R), remained in effect during Segment I of the current pro-ject. In light of the above, only two lease ground investigations were performed during Segment I. An investigation of the two lease-applications, both of which were located in Little Egg Harbor Bay, found them to be productive in terms of natural hard clam re-cruitment. Following a review of the biological reports submitted for these lease applications, the Atlantic Coast Shellfish Council

denied both leases so that these areas could remain available for public use. Seven other applications were cancelled 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. Although originally scheduled to be lifted in the spring of 1986, the moratorium on lease applications was not lifteduntil October 1986. It may be necessary, however, to reinstate the moratorium since the staff of the Bureau of Shellfisheries is more limited than in previous years.

JOB NO. 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 71 million clams have been utilized from condemned waters. The intensive sampling program of the Inventory Program (Job I) 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 participant. During Segment I, 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. Harvest and catch per effort data by area are included in Attachment B. Table I (Attachment B) includes the relay summary data for 1985 as well as the first six months of 1986. Harvest data for specific relay harvest areas (i.e. 1-il, W, X, Y, Z) are not in-cluded for the 1985 data as staffing limitations prevented the extraction of that information from the relay harvest receipts. However, the recent acquisition of an IBM personal computer has greatly ameliorated this arduous task and has facilitated improved monitoring of harvest from specific relay areas. The continued use 

                                  -  31 -

of the IBM pc will improvethe management of the hard clam stocks associated with this program. The total reported harvest for all relay areas in 1985 was 5,144,862 clams. Those previously mentioned areas of northern Monmouth County (excluding the Manasquan and Shark Rivers) received the most activity with 3,646 man-days of effort and a resultant har-vest of 4,.855,254 clams (over 94% of the total 1985 relay harvest). The mean catch per effort for all relay areas in 1985 was 1316 clams/man/day, which is up 12.9% from the 1984 figure. It is un-known whether this increase is due to an actual increase in harvest or more accurate reporting by participating shellfishermen. The harvest data of the first six months of 1986, as shown on Table I (Attachment B), provides a more precise representation of the relay harvest. During this period, 1797 man-days of effort yielded a total reported harvest of 2,422,730 clams and a mean catch per effort of 1348 clams/man/day. Section 11 in Raritan Bay yielded the highest catch per effort (1,675 clams/man/day), but contributed only 22,343 clams to the total harvest for the first half of 1986. Shark River had the lowest catch per effort during this period (963 clams/man/day), although this figure is up approximately 19% from the Shark River catch per effort figures for 1984 and 1985. Relay totals for Segment I are up substantially from those of Segment V of the previous project (3-332-R) . The reported relay harvest for Segment I was 5,747,953 clams, up 47.2% from the previ-ous segment. Effort (4322 man-days) and catch per effort (1330 clams/man/day) were up 26% and 16.9%, respectively, in comparison

to the previous segment. The factors contributing to these in-creased figures are unknown, and speculation on the matter would be of little merit.

JOB NO. 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 program, bed condition, and oyster mortality. The regular monitoring of the seed and market beds continued to determine setting success, mortality and overall bedcondition. 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 within each sampled. 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 relatively poor condition in comparison to 1984 figures. French's Point consisted of 65.8% oyster with a mean annual mortality of 34..6%. Moss Point data was nearly identical, being composed of 65.5% oyster with a mean annual mortality of 36.6 percent. In contrast, French's Point and Moss Point beds consisted of 85.3% and 94.8% oyster (respectively) in 1984 and had annual mortalities of three percent or less. Although 

                              -  34 -

showing a decline in bed condition, both seed beds experienced a good set in 1985. The age composition of French's Point consisted of 59.9% spat with Moss Point consisting of 39.3% spat. The Mullica River market beds, with infrequent natural set, greater disease and predation pressure, and periodic harvest, con-tinued to exhibit a decline .in bed condition since being planted during the transplant programs of 1979-1981. The annual sampling of the market beds indicated that the Fitney Bit bed was composed of only 16.8% oyster and had a total mortality of 46.1 percent. The Reef Bed consisted of virtually 100% shell as only nine live oysters were collected in nearly seven bushels of shell. The es-timated mortality was 52.6%, although the sample size was minimal. Samples of oysters collected from the seed and market beds were sent to the Rutgers Oyster Research Laboratory in Bivalve, New Jersey for histoligical examination. Sample analysis confirmed that the parasite Haplospordium nelsoni (MSX) is at least partly responsible for the high mortalities observed on all beds. In addition, the protistan parasite Perknsus marinus ("Dermo") was detected in three oysters collected from the Moss Point bed and was determined to have caused the death of one. gaper examined. The extensive oyster mortalities experienced in the Mullica River estuary during Segment I were comparable to those experienced in Delaware Bay during the same period.
