ABSTRACT The multi-agency Puget Sound Dredge Disposal Analysis Program has been delegated the task of evaluating, selecting, monitoring and managing sites within the inland waters of Washington State for long-term, unconfined disposal of un contaminated dredged materials. The Disposal Site Work Group of PSDDA was assigned the responsibility of selecting unconfined, open water disposal sites in Puget Sound based on nineteen selection factors covering physical parameters, human uses, historical biological ~resource data and site-specific trawl investigations. This document is one of two final technical reports detailing the results of the site-specific trawl surveys for Phase II PSDDA disposal sites located in North and South Puget Sound (the results of Phase I (Central Puget Sound sites) trawl surveys can be found in Dinnel et al. (1986)). The results of invertebrate resource assessments using a 3-m beam trawl are contained in this report. Results of the bottomfish investigations using a 7.6-rn otter trawl are contained in a parallel report by Donnelly et al. (1988). Phase II trawl surveys were conducted in the Nisqually Delta area of South Puget Sound and in Bellingham Bay, North Puget Sound. Trawling was conducted seasonally in and around two “non-dispersive” Zones of Siting Feasibility (ZSFs) in each area. Additionally, winter and summer trawling was also conducted in and around four tentative “dispersive” ZSFs, one located south of Point Roberts in the Strait of Georgia, one in Rosario Strait and two in the Strait of Juan de Fuca (one site each near Port Townsend and Port Angeles). The beam trawl survey in the Nisqually area identified the following invertebrate resources of concern: Dungeness and rock crabs, pandalid shrimp, and sea cucumbers. Generally, Dungeness crab were scarce, rock crab (especially the purple crab, Cancer gracilis) were abundant, pandalid shrimp sparse, and sea cucumbers (Parastichopus californicus) plentiful. Of the two Nisqually ZSFs, the eastern ZSF (ZSF #2 near Ketron Island) contained fewer invertebrate resources, all of which were relatively scarce compared to the Nisqually region in general. Beam trawling in Bellingham Bay identified the following invertebrate resources of concern: Dungeness and rock crabs, pandalid shrimp, sea cucumbers, and the large pink nudibranch, Tritonia diomedea, which is used as a neurophysiological research tool. Dungeness crab were more abundant than rock crab in Bellingham Bay. Several species of pandalid shrimp were abundant and served as the basis of a small commercial and sport fishery. Sea cucumbers were scarce and Tritonia were in low to moderate densities. Within the two proposed ZSFs, Dungeness crab and Tritonia densities were moderate and pandalid shrimp densities were gene rally high. On the basis of resource densities, neither ZSF could be recommended over the other. Catches of invertebrate resources in the dispersive Strait of Georgia ZSF were small, being limited to a few shrimp, scallops and sea urchins. Catches in Rosario Strait consisted of moderate numbers of pink scallops and sea urchins and low numbers of pandalid shrimp. Abundances of these resources were highest in the southern half of Rosario Strait. Invertebrate resources were similar in the dispersive Juan de Fuca ZSFs near Port Townsend and Port Angeles and consisted primarily of pandalid shrimp, pink scallops and sea urchins. Pink scallops and sea urchins were generally in high
abundance in each ZSF, while pandalid shrimp (mostly juveniles of several spe cies) were especially abundant during the October sampling period. Additional work will be required to identify sites with low resource densities in the Strait of Juan de Fuca.

PUGET SOUND DREDGE DISPOSAL ANALYSIS (PSDDA) DISPOSAL SITE INVESTIGATIONS: PHASE II TRAWL STUDIES IN NORTH AND SOUTH PUGET SOUND Invertebrate Resource Assessments INTRODUCTION In January 1986, the Disposal Site Work Group (DSWG) of the Puget Sound Dredge Disposal Analysis (PSDDA) team selected preliminary preferred and alternative sites for the unconfined disposal of dredged materials in the main basin of Puget Sound (Phase I area). Initial disposal sites were selected based on information gathered from limited field studies conducted within the Zones of Siting Feasibility (ZSFs) and existing information from each ZSF. Selection of the final preferred disposal sites required more detailed evaluations of important physical factors and biological resources in and around the identified sites. Hence, trawl surveys of each of the proposed sites were conducted on a seasonal basis in 1986. These trawl data (Dinnel et al. 1986a), which provided spatial, temporal, density and life cycle information on important demersal invertebrate and epibenthic fishery resources, were used to help select final disposal sites that would least impact these resources. A similar siting process (Phase II) was initiated in late 1986 to select another group of disposal sites in the north and south areas of Puget Sound. Once again, seasonal trawl surveys were conducted in 1987 in and around two sites in each area designated as “non-dispersive” (near Nisqually Delta and Bellingham Bay) and four sites designated “dispersive” (near Point Roberts in Georgia Strait, Rosario Strait, and two sites near Port Angeles and Port Townsend in the Strait of Juan de Fuca; Figure 1).

This report describes the findings of the trawling studies conducted in and around the Phase II disposal sites during February, April-May, July and October 1987. The findings of the beam trawl surveys, which primarily focused on demer sal invertebrate resources, are summarized. A related report (Don~elly et al. 1988) describes the findings of the otter trawl surveys for these same areas. The otter trawl primarily targeted bottomfish resources but also provided some information on invertebrates. Additionally, a rock dredge was used in Rosario Strait owing to the very rocky bottom. The fish and invertebrate data obtained from the rock dredge are summarized in their respective reports.
METHODS
General All trawllng was conducted from the 16-rn research vessel Kittiwake. The otter trawl is described in Donnelly et al. (1988). Descriptions of the beam trawl and rock dredge follow below. In addition to trawling, surface and bottom water samples were collected by Niskin Sampler and measured for temperature, salinity and dissolved oxygen. These data are summarized in Donnelly et al. 1988. Trawl cruises were conducted on the following dates: 9 Feb-i March (non-dispersive sites only); 6-20 April (dispersive sites only); 6-13 May (non-dispersive sites); 8-24 July (non-dispersive sites); and 12-31 Oct (all sites). Gear Beam trawl. Demersal invertebrate fauna were sampled with a 3-rn beam trawl (Figure 2; Gunderson and Ellis 1986) previously used elsewhere in Puget Sound (Armstrong et at. 1987; Dinnel et at. 1985a, 1985b, 1986a, 1986b, 1987, 1988; Weitkamp et at. 1986). The beam trawl was towed approximately 232 meters (1/8 nautical mile (NM)) at a target ground speed of 2.5 km/hr (1.4 knots), which yielded
3
an area swept by the net (opening
=
2.3 m) of 534 m2. All crabs caught in the
trawls were measured for carapace width (CW), sexed, assessed for molt condition (degree of shell softness) and reproductive condition (females with or without eggs), and returned to the water. Catches of shrimp were preserved for later pro cessing in the laboratory, where all pandalid shrimp were identified and measured for carapace length (CL). Other demersal resources such as scallops, sea cucum bers, sea urchins, mussels and starfish were counted and returned to the water. Rock dredge. A rock dredge (86-cm wide x 38-cm high; Figure 3) was used to sample Rosario Strait and a few stations in the Strait of Georgia owing to the pres ence of rock and/or cobble on the bottom. The dredge was towed approximately 185 m (0.1 NM) unless obstacles necessitated a shorter distance. The large mesh of the rock dredge bag was lined with a beam trawl cod-end liner (5 mm mesh). The catches made with the rock dredge are considered qualitative since sampling efficiency is unknown and probably quite variable depending on bottom type. All animals caught in the rock dredge were processed as noted above for the beam trawl.
Sample Sites Beam trawl sample sites in the Nisqually area consisted of six stations in each ZSF (ZSF 2 and 3) and stations at selected depths (typically 10, 20, 40, 60 and 80 m) along five arbitrarily chosen transects in the Nisqually Delta/Anderson Island area (Figure 4). Four additional stations (A-D) were also added to provide better coverage in the deep-water areas between some of the transects. Otter trawl stations were a subset of the beam trawl stations and included all of the ZSF 2 and ZSF 3 stations. Bellingham Bay sampling stations were selected to give general coverage to the entire bay, since the selected ZSFs in this location were tentative. Stations
4
stratified by depth (10, 15, 20, 25 and 30 m) were established along four transects and an additional 10 stations (A-J) were randomly chosen in the deeper portion of Bellingham Bay (the most probable area for location of a disposal site; Figure 5). Otter trawl stations consisted of the randomly chosen stations (A-J) and a subset of the beam trawl transect stations. Sampling stations in the Point Roberts dispersive ZSF area included five stations (1-5) within the preliminary ZSF boundary, one station to the north (6) and one station to the south (7) of the ZSF; four stations (8-1 1) were selected for data continuity since these same stations were sampled by beam trawl in 1985-1 986 as part of a University of Washington/Sea Grant project (Dinnel, unpublished data). All 11 stations in this area were sampled with both the beam and otter trawls except Stations 5 and 7, which were sampled with the rock dredge owing to a rocky bottom. Beam trawl and otter trawl sampling was originally planned for six stations in Rosario Strait. However, since initial sampling with the beam trawl showed that the bottom was rocky (demolished nets and chains), the rock dredge was used and the number of stations increased to 11 to provide better spatial coverage (Figure 7). Sample locations in and around the Port Townsend ZSF included four stations (1-4) inside the ZSF boundaries, one station to the northeast (5) and one station to the southeast (6; Figure 8). Al! six stations were scheduled to be sampled by both beam and otter trawls, but rough weather caused the cancellation of beam trawis at three stations in April. Samples were collected near Port Angeles from four stations (1-4) within the ZSF boundaries and from two stations (5 and 6) east of the ZSF (Figure 9). All six stations were sampled with both beam and otter trawls. The exact locations and depths for all sampling stations in each of the six regions are recorded in Appendix Tables 1-6.
5
Quality Assurance/Quality Control (QA/QCI The location of each trawl station was found using a combination of radar ranges to permanent features and fathometer readings. When available, stations were located with LORAN C coordinates. Once the stations were located, the beam trawl was deployed at a target boat speed (relative to the bottom) of about 1.5 knots. Winch “wire out” at each station was set by precalculated ratios (ranging from 3:1 to 10:1, wire out:depth) that were dependent on depth and gear type. Each beam trawl was towed at a target ground speed of 1.4 knots for 1/8 NM (232 m) following pre-specified depth contours (for slopes) or compass headings (for flat bottoms). Elapsed time for each tow was monitored and the tow discarded if the elapsed time was 25% more or less than expected (i.e., 1.75 knots). Tows were also discarded and repeated if any other significant discrepancies were noted (e.g., gear hang-ups, tangled, torn or unexpectantly empty net, etc.).
Data Analyses All beam trawl catches of demersal invertebrates were converted to estimated densities based on calculations of the area swept by the beam trawl. Area swept was estimated from previous underwater measurements of net opening (2.3 m), observations of net behavior, and measurements of actual “net on bottom” times using ultrasonic transmitters on the net (Gunderson, unpublished data). In this report, the term “density” or “estimated density” (e.g., crab/ha) has been used without any corrections for net capture efficiency. Therefore, “densities” reported herein specifically refer to an index of estimated densities that should provide the best relative measures of demersal resources present as well as trends in abundances between areas, between seasons and between years.

RESULTS
Nisgually The Nisqually region of Puget Sound is extremely rich and diverse in inverte brate fauna. The habitat types are also diverse and include rocky areas around Ketron Island, current-swept sand bottoms off the Nisqually Delta, low current areas near several coves on Anderson Island and silty bottoms in and around the two ZSFs (Figure 4). Resources of potential fisheries importance included Dungeness (Cancer magister) and rock (C. productus and C. gracilis) crabs, pandalid shrimp and sea cucumbers. The area was also very rich in other invertebrate fauna, including starfish (a wide variety of species), sessil tunicates, anemones, brachio pods and gastropods. An occasional pink scallop was also caught along the west side of Ketrön Island. Dungeness craL2, Dungeness crab were caught in small numbers in front of and on either side of the Nisqually Delta (Figure 10). The average estimated density of crab for all seasons and stations combined (n
=
214 beam trawl tows) was 3
crab/ha, decreasing from 5 crab/ha in February to 1 crab/ha in October (Figure 11). Analyses of the basic biological data for this species (Figure 12) shows that all crab caught were large, mature individuals over 120 mm carapace width (CW). Females slightly outnumbered males in the catches except in October, when only several males were caught. Possibly, females were not caught in October because they had extruded new egg masses and were buried in the substrate (thus, un available to the trawl gear; Dinnel et al. 1988). A few gravid females were found in February with eggs ranging in age from medium to spent. The shell conditions of all Dungeness crab were hard to very hard
(=
old to very old) except in May, when
about one-third of females had recently molted (and probably mated during molt ing). The depth distribution of Dungeness crab varied by sex and season. Males
7
were usually caught in shallow water (≤20 m) except for October. Females were caught at all depths in February, in shallow water during molting and mating in May and to intermediate depths in July. The location of the females in October is un known, but information from other areas (Armstrong et at. 1987, Dinnef et al. 1988) suggests that females (probably gravid) move to relatively shallow areas during the fall/early winter. Rock crabs. Rock crabs (Cancer productus and C. gracilis) were much more plentiful (average for all beam trawis were Dungeness crab (average
=
=
156 crab/ha) in the Nisqually region than
3 crab/ha). In general, C. gracills outnumbered
C. productus by roughly 10-fold in the catches. The basic biological information for C. productus caught in the Nisqually area is summarized in Figure 13. Generally, females were more abundant in the catches than males except for October. Gravid females were most prevalent in the Febru ary samples, and the age of the egg masses varied from new to spent. Recruitment of juveniles started in about July. The young-of-the-year (YOY) dominated the catches in October and had grown to a size ranging from 10 to 30 mm. Both male and female C. productus occurred to depths >100 m, with little clear indication that a specific depth interval was favored. Similar biological data are summarized for C. gracilis in Figure 14. Males and females were caught in essentially equal numbers in February and May, while the catches were dominated by males in July and October. Gravid females and juve nile crab were caught during each season. The age of the egg masses also varied during each season. Hence, the spawning and settlement times for this species are distinctly less seasonal than for C. magister or C. productus. Cancer gracilis was found to depths of 100 m but generally favored depths 60 mm were found in Bellingham Bay in contrast to a relatively healthy population >60 mm in the Nisqually area (Figure 14). The reason(s) for the different age structure between the two areas is presently unknown. The distribution of C. gracilis was limited primarily to shallow areas in February and May, but covered all depths in July and October, in large part due to the wide distribution of the newly settled YQY (Figure 32). Tanner crab. Tanner crab (Chionoecetes bairdi—also commercially known as snow crab) were found in small numbers in the Beltingham Bay samples but would
12
have to be considered more of an “incidental observation” since this species does not support any fishery in the inland waters. The individuals caught in Bellingham Bay were mostly juveniles that probably settled from November-January and grew to an average size of ~-50 mm CW by October (Figure 33). Males slightly outnum bered the females (except in February) and their overall distribution was deep (2530 m) and restricted to the mid-bay area. Pandalid shrimp. Bellingham Bay proved to be relatively rich in commercial shrimp resources compared to many other areas of Puget Sound. All seven species of pandalid shrimp recorded in this study occurred in Bellingham Bay, although the spot prawn, P. platyceros, and the pink shrimp, P. jordani, were scarce (Figure 16). Bellingham Bay was especially rich in P. hypsinotus, P. danae, and P. borealis. The overall average (all seasons, stations and species combined; n
=
155 beam trawl tows) estimated density was 600 shrimp/ha with a seasonal range of 413 shrimp/ha (May) to 942 shrimp/ha (February). Shrimp were caught at most stations in Bellingham Bay, with the highest densi ties generally being caught in the deeper (25-30 m) mid-portions of the bay (Figure 34). The one exception to this was substantial catches of juvenile P. danae in July and October at some of the shallow areas (10-20 m), especially in the Post Point area. Relatively few P. platyceros and P. jordani were caught; hence, little information is available regarding timing of egg extrusion and juvenile recruitment. For the other shrimp species, egg-bearing females were only caught in the February trawls excepting a few gravid P. danae also found in the May trawls (Figure 24). No gravid P. dispar were caught. Recruitment of juvenile YOY shrimp was first noted for most species in the July trawls, except P. hypsinotus, which were not caught as YOY until October (Figures 1 7-23).
13
Besides providing estimates of shrimp densities, the trawl sampling also produced information on the age structure of shrimp populations in Bellingham Bay. For some species (P. platyceros, P. dispar and P. jordan,), only one yearclass of shrimp was evident in the trawls at any one time. For several other species (P. borealls, P. goniurus and P. hypsinotus), two year-classes were generally present while three year-classes were evident for P. danae (Figures 17-23). From these size-frequency plots, growth and relative abundances of each of the yearclasses can be traced. Other invertebrates, The large pink nudibranch, Tritonia diomedea, is considered a valuable neurophysiological research tool because of its large nerve fibers. Consequently, this species has been “harvested” in Bellingham Bay by researchers.from Friday Harbor Laboratory and elsewhere. Bellingham Bay is a favored collection site because this somewhat ephemeral animal can usually be obtained there. Our trawl sampling showed that the average estimated density of Tritonia in Bellingham Bay in 1987 was 13 animals/ha with a seasonal range from 21/ha (February) to 6/ha (October). The distribution patterns for Tritonia catches (Figure 35) showed that it was not abundant anywhere in Bellingham Bay, but that the bulk of the animals caught were found at the deeper (20-30 m) stations in the mid-portions of the bay. Compared to the Nisqually area, Bellingham Bay was relatively poor in starfish diversity. However, there was a high biomass of the fragile starfish, Luidia foliolata. This species is singled out for two reasons: (1) It occurred in large numbers and biomass in some of the trawls and (2) this species has been reported to be a nuisance by-catch in the bottomfish trawl fishery in this area, so much so that some areas of the bay are avoided by the fishermen (Gary Davis, pers. comm.). The’seasonal distribution patterns of the Luidia catches (Figure 36) show that this species was caught at most stations in the bay, but that the highest catches
14
were generally from the southern, mid-portion of the bay. The average overall estimated density of starfish for all trawls (n
=
155 beam trawl tows) in Bellingham
Bay in 1987 was 256 starfish/ha, of which 242/ha was Luidia. The Luidia popula tion was relatively stable between seasons, ranging from a low of 198 individuals! ha (October) to a high of 319/ha (July). By-station and by-season densities of Luidia in Bellingham Bay are summarized in Appendix Table 7. Other than Tritonia and Luidia, few other invertebrate “resources” were noted from Bellingham Bay (Figure 26). Bellinçiham Bay disposal areas.

beam trawl tows for each ZSF) for each of the invertebrate “resources” listed in Table 2 show that Dungeness crab were least plentiful in the south ZSF, rock crabs and Tritonia roughly the same in each ZSF, and shrimp and starfish (essentially all Luidia) in greater abundance in the south ZSF. Only in the case of shrimp (south ZSF) and Tritonia (south ZSF) did “resource” densities in the ZSFs exceed the baywide averages (Table 2) and, in the case of Tritonia, the relatively high average was caused by a one-time peak density of about 55 Tritonia/ha in February.

Figures 37 and 38 graphically illustrate the average densities of invertebrate resources caught by beam and otter trawls in each ZSF for each season. Com parison of these two figures shows the greater efficiency of the beam trawl for sampling invertebrate resources with the exception that estimates of shrimp densities were generally higher for the otter trawl.
Strait of Georgia The preliminary ZSF sited in the southern Strait of Georgia south of Point Roberts is located in deep water (200-210 m depth) close to the U.S.-Canada boundary and in an area of high currents, turbulence and mixing. The northern portion of the ZSF is located over a sand bottom where large catches of brittle stars were common; the southern portions of the ZSF bordered on a rocky bottom (characteristic of Alden Bank and the Patos, Sucia, and Matia islands) where catches of mussels (Modiolus) and sea urchins were possible (as well as rock damage to the trawls). In general, invertebrate resources were sparse in and around the proposed ZSF. The distributions of Dungeness crab, shrimp, scallops and sea urchins are
graphically presented for the April and October cruises in Figures 39 and 40. Dungeness crab. No Dungeness crab were caught within the boundaries of the ZSF during either cruise. This species was limited to depths ≤100 m and were especially abundant at the 50-rn station (Station 10) as has also been shown during previous sampling at this location (Dinnel, unpublished data). The average densities of Dungeness crab for each cruise (excluding Stations 5 and 7, n
=
9
beam trawl tows each season) were 46 crab/ha in April and 17/ha in October (Figure 11). Note, however, that these averages are based on catches of crab at only 3 of 11 stations (Stations 9, 10, 11), and that the average densities for only
16 these 3 stations would be 138 and 50 crab/ha for April and October, respectively. Hence, the preferred areas for Dungeness crab appear to be outside the ZSF. Figure 41 details some of the basic biological data for Dungeness crab in the Strait of Georgia. Males dominated the catch by about 2:1 over the females, and juveniles were rare. The majority of the females caught in October were gravid with new egg clutches, while one female caught in April had a spent egg clutch. Shells were hard for all crabs caught in both April and October. The size-frequency plots in Figure 41 show that most crabs in the catches were mature adults over 100 mm CW with the very notable exception of a group of subadult males between 80-100 mm CW caught in April. This observation is significant because our sampling has rarely identified habitats utilized by 1- to 2-year-old crabs (i.e., 30-1 00 mm ani mals). This.information—and the depth-distribution graphs of Figure 41—suggest that subadult males distinctly prefer the 50-rn contour off Birch Bay. Rock and tanner crabs. Rock and tanner crabs were relatively scarce in the Strait of Georgia samples (Figure 11). Pandalid shrimp. Pandalid shrimp catches were spotty and relatively small. The average estimated densities for each season (excluding Stations 5 and 7; n
=
9 beam trawl tows) were 44 and 71 shrimp/ha for April and October, respectively. The catches primarily contained P. danae at the shallower stations and P. borealis at the deeper stations, with an occasional P. dispar in the catches (Figure 16). Size-frequency distributions for each shrimp species caught in the Strait of Georgia (graphed in Figures 17-23) show that several year classes of P. d!spar P. danae and P. borealis were present. Other invertebrate resources. Both pink scallops, Pecten rubida, and weathervane scallops, P. caurinus, were caught in very small numbers at a few stations (average of 6 and 19 scallops/ha for April and October, respectively; n
=
9
17
beam trawl tows) each season (Figure 40). Weathervane scallops were rare compared to pink scallops. A few sea urchins (Strongylocentrotus pallidus) were caught within the ZSF, indicating a hard bottom in the southern portion of the ZSF (Figure 40).
Rosario Strait Rosarlo Strait is a current-swept passage lying between Decatur and Lopez Islands on the west, Fidalgo Island to the east and Cypress Island to the north. The bottom type ranges from gravel in the northern portion to cobble and rock outcrop pings in the southern portion. Eleven stations in Rosario Strait were sampled by rock dredge during April and October. Each tow with the rock dredge was roughly 0.1 NM. Since the sampling efficiency of a rock dredge bouncing on a rocky bottom must be very poor, no attempts were made to estimate resource densities from the these tows. Crabs. Dungeness and rock crabs (except for small and plentiful Cancer oregonensis) were completely absent from the rock dredge samples during both seasons. Shrimp. A relatively large number of small, non-pandalid shrimp were caught in the rock dredge, but only a few pandalid shrimp (mostly small P. danae; Figure 19) were caught at each station (Figures 16, 42 and 43). Other invertebrate resource& Pink scallops were fairly common in the rock dredge samples from the southern half of Rosario Strait and absent from the four northernmost stations, which typically had sand and gravel bottoms (Figures 42 and 43). Sea urchins (S. pallidus) and mussels (Modiolus) were also caught in fairly large numbers at the southern stations (Figures 42 and 43). Catches of these species at the southern stations indicates a very rocky bottom.
18
Port Townsend The Port Townsend ZSF was located northeast of Port Townsend at the head of Admiralty Inlet. Six stations were sampled in and around the ZSF with both beam and otter trawls (except that three stations were not sampled by beam trawl in April because of high winds and rough seas). The station depths ranged from 70 to 150 m. The bottom was probably a mixture of sand, small gravel and shell. Crabs. No Dungeness, rock or tanner crabs were caught in this area during either sample season. Pandalid shrimp. A modest average donsity of 236 shrimp/ha (all stations combined; n
=
6 otter trawl tows) was estimated for this area in April. The average
density of shrimp estimated in October otter trawl catches increased dramatically to 6,802 shrimp/ha, primarily due to an influx of young P. danae and P. borealis (Figure 16). The distributions of shrimp in the Port Townsend area were similar during the two seasons sampled (Figures 44 and 45) and the highest catches were made at Stations 4 and 6 (stations closest to Port Townsend). In each case, the catches were dominated by P. danae. Few shrimp were caught at Stations 1 and 5. Pandalus platyceros, P. jordani and P. hypsinotus were not caught in this area, and relatively few P. dispar and P. goniurus were in the catches. The few P. dispar that were caught were mature shrimp averaging about 25-30 mm CL except for a few juveniles caught in October (Figure 18). The few P. goniurus, caught only in October, were all juveniles averaging 10 mm CL (Figure 22). P. borealis caught in the April sampling were of two size groups, averaging about 10-12 mm and 16-17 mm CL, while the October samples were dominated by YOYs averaging 9-10 mm (Figure 21). The size-frequency plot for P. danae (Figure 19) caught in April also suggests there were two size groups for this species, averaging 10-12 mm and 1720 mm CL. The number of P. danae caught in October also increased roughly two
19 orders of magnitude but, unlike P. borealls, the increase in numbers appeared to be due to an influx of 1- to 2-year-old animals rather than due to settlement of YOY (Figure 19). Other invertebrates. Pink scallops were abundant at some of the Port Townsend stations, although the catches were spotty. The scallop catches (based on the October beam trawl samples—sampling with this gear was incomplete in April and the otter trawl is a poor sampling gear for scallops) were highest at Stations 1 and 4, with estimated densities of 2,172 and 8558 scallops/ha, respect ively; and lowest at Stations 2, 3 and 5, where no scallops were caught in October (Figure 44 and 45). At present, it is unknown how consistent these apparent aggregations of scallops will be in future years. Large numbers of sea urchins (S. palildus, possibly S. droebachiensis, and a few rare Allocentrotus) were caught at three of the Port Townsend stations (Stations 1, 4 and 6), which were the same stations where the highest scallop catches were made (Figures 44 and 45). The estimated urchin densities at these three stations (based on October beam trawls) ranged from 2,079 to 8,521 urchins/ha. Very few urchins were caught at the other three stations (Stations 2, 3 and 5). Other invertebrate “resources” were limited primarily to modest numbers of a variety of starfish species (Figure 26). Port Angeles The Port Angeles ZSF is located north of Port Angeles and Ediz Hook in the middle of the Strait of Juan do Fuca and adjacent to the international boundary. The eastern portion of the ZSF is also adjacent to a rocky reef area locally known as the “rock pile” (a popular fishing spot). The station depths ranged from 110 to 136 m and the bottom type was apparently a sand/gravel mix with some shell.
20
Crabs. As was true for the Port Townsend site, no crabs were caught in the Port Angeles ZSF. Pandalid shrimp. Few shrimp (average density
=
53 shrimp/ha; n
=
6 beam
trawis) were caught in the trawls in April, and the majority (—90%) of those caught were P. borealls (Figure 16). However, catches of shrimp in October jumped more than two orders of magnitude (average estimated density
=
6,775 shrimp/ha) owing
entirely to settlement of YOY P. borealis averaging about 8-9 mm CL (Figure 21). Unlike Port Townsend, no P. danae were caught in the Port Angeles area. The balance of the shrimp catch at Port Angeles consisted of a few P. dispar and P. goniurus. The distribution of the April shrimp catches was uniformly low at all stations and the largest catch (206 shrimp/ha) was at Station 5 (Figure 46). However, the very high catches in October were not evenly distributed; about 94% of the shrimp were caught at only 3 stations (Stations 1, 2, 3) with catches of 26,462 to 68,927 shrimp/ha (Figure 47). Other invertebrates. Pink scallops were caught in large numbers in April (average beam trawl density = 2,781/ha) and October (average
=
1,323 scallops!
ha). The highest densities (up to 4,551 scallops/ha) were caught at Stations 2, 3, 4 and 5 during each season. Scallops were essentially absent from Station 6 (Figures 46 and 47). Sea urchins (S. pallidus) were also plentiful in most of the trawl samples from Port Angeles during both seasons (average densities
=
1,486 and 2,260/ha for
April and October, respectively). However, unlike Port Townsend, the highest sea urchin densities did not correspond to high scallop densities. The highest sea urchin catches were at Station 6, which was almost devoid of scallops. The distri bution of sea urchins was fairly uniform between stations, with Stations 5 and 6 producing the largest catches during both seasons (Figure 46 and 47).
21
Other invertebrate “resources” caught in the Port Angeles area were limited to moderate numbers of a variety of starfish species and a few sea cucumbers (Figure 26).
DISCUSSION AND CONCLUSIONS
Nisgually Region In 1987, the primary invertebrate species of actual or potential commercial and sport fishery concern caught in The Nisqually region were Dungeness and rock crabs, pandalid shrimp and sea cucumbers. Dungeness crab were sparse yet of concern for two reasons: (1) crab were caught near the south boundaries of both ZSFs, and (2) this population of crab supports a small sport fishery in the Nisqually Delta region~(Ron Westley, per. comm.). The recruitment dynamics of Dungeness crab in this area are unknown, but larvae may come from the few local resident females or recruitment might be dependent on larvae transported southward through the Tacoma Narrows from the main basin of Puget Sound. The generally shallow distribution observed in May might be a reflection of mating and molting activities. All Dungeness crab caught in the Nisqually region were mature indi viduals over 120 mm CW. This size distribution suggests that these animals all came from one or two successful periods of juvenile recruitment about 3-5 years ago and that settlement has not been successful in recent years. The larger sizes of Dungeness crab from the Nisqually (especially the females), together with a general appearance of good health, suggests that the Nisqually area could support more Dungeness crab if settlement (and/or juvenile survival?) were more successful.
Other Cancer crabs present in the Nisqually region were the rock crabs C. productus and C. gracills. Cancer productus is utilized for food by some sport
22 crabbers and divers, while the more plentiful C. grad/is is less extensively fished because of its smaller size. Rock crabs tend to be more important in sport catches when Dungeness crab are unavailable. Cancer productus is also a potential commercial species, since the large claws of this species now appear in California fish markets. Pandalid shrimp were generally sparse in the Nisqually region with the possible exception of P. danae. However, most of the P. danae were young individuals (CL 100
