Both upper and lower antennular flagella of similar length, attached to tip of antennular peduncle. 1 Carapace lacks both postorbital and postantennal spines, cervical groove in- distinct or absent.

In males, endopod of second pair 5 of pleopods (abdominal appendages) with appendix masculina only. Third and fourth pleopods single-branched. Telson generally armed with a pair of fixed lateral spines. Colour: body colour varies from dark brown to reddish; often with distinct spots or colour markings on carapace and/or abdomen - such colour markings are specific and very useful in distinguishing the species. Habitat, biology, and fisheries: All members of this family are marine and can be found from shallow to deep waters (to depths of more than 400 m). They are all benthic and occur on both soft and hard bottoms. Their sizes are generally small, about 2 to 8 cm, but some species can reach a body length over 15 cm. The sexes are easily distinguished by the presence of a large copulatory organ (petasma) on the first pair of pleopods of males, while the females have the posterior thoracic sternites modified into a large sperm receptacle process (thelycum) which holds the spermatophores or sperm sacs (usually whitish or yellowish in colour) after mating. -
Rockfish Populations Around Galiano Island Freedom to Swim: Research Component for Rockfish Recovery Project
GALIANO CONSERVANCY ASSOCIATION Rockfish populations around Galiano Island Freedom to Swim: Research Component for Rockfish Recovery Project 2013 Rockfish populations around Galiano Island Page 2 of 18 Executive Summary Rockfish (Sebastes), of the Scorpionfish family, are unique to the Pacific Northwest. As of 2012 there are 8 species listed as threatened or of special concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Canary, Quillback and Yellowmouth rockfish are listed as ‘threatened’; Rougheye Type I, Rougheye Type II, Darkblotched, Longspine Thornyhead, and Yelloweye (outside waters and inside waters populations) rockfish are listed as ‘special concern’. Both species of Rougheye and both populations of Yelloweye rockfish are also listed under the Species At Risk Act as ‘special concern’. These predatory fish can live at great depths, and tend to live very long lives of 80 or more years (Lamb and Edgell, 2010). These factors, when combined with their primarily territorial lifestyles, have made them particularly susceptible to overharvest. There is a strong need to protect these species with enforced no‐take marine protected areas, and we can only hope that recent conservation efforts will be enough to recover some of the most depleted populations (Lamb and Edgell, 2010; McConnell and Dinnel, 2002). In the late 1980s the commercial rockfish fishery boomed, which led to a series of management responses in the 1990s to attempt to recover the rapidly depleting stocks in BC (Yamanaka and Logan, 2010). This also occurred in the US as a direct result of pressure on the salmon stocks ‐ fishermen were urged to divert their attentions to bottom fish (McConnell and Dinnel, 2002). -

San Diego, CA 92123 ph: (858) 534-7284 Bodega Bay, CA 94923-0247 [email protected] ABSTRACT The California spiny lobster (Panulirus interruptus) population is the basis for a valuable commercial and recreational fishery off southern California, yet little is known about its population dynamics. Studies based on CalCOFI sampling in the 1950s indicated that the abun- dance of phyllosoma larvae may be sensitive to ocean- ographic conditions such as El Niño events. To further study the potential influence of environmental variabil- ity and the fishery on lobster productivity, we developed a 60-year time series of the abundance of lobster phyl- losoma from the historical CalCOFI sample collection. Phyllosoma were removed from the midsummer cruises when the early-stage larvae are most abundant in the plankton nearshore. We found that the abundance of the early-stage phyllosoma displayed considerable inter- annual variability but was significantly positively corre- Figure 1.

Cypris settled predominantly on the carapace (67%), mostly on the gastric area (40%), on the left or right orbital areas (35%), on the head appendages, and on the pereiopods 1–3. Encrusting individuals were mostly small (84%); medium-sized specimens accounted for 11% and large for 5%. On the cephalothorax, most were observed in branchial (661) and orbital areas (240). Only 40–41 individuals were found on gastric and cardiac areas. Some individuals (246), mostly small (95%), were observed on the dorsal portion of somites. -

Asc Shrimp Standard Revision
ASC SHRIMP STANDARD REVISION Revision of Current Metrics Background Analysis Document March 2020 Revision of current metrics – Background analysis document Shrimp Standard Revision Purpose The purpose of this document is to present the acquired data for the revision of the ASC Shrimp Standard v.1.1 and propose changes to the metric requirements where relevant. This document will be used for the decision-making process within the revision. Background The ASC Shrimp Standard v.1.1 is based on the anterior work of the Shrimp Aquaculture Dialogue (ShAD) and sets requirements that define what has been deemed ‘acceptable’ levels as regards the major social and environmental impacts of saltwater shrimp farming. The purpose of the ASC Shrimp Standard was and is to provide means to measurably improve the environmental and social performance of shrimp aquaculture operations worldwide. The Standard currently covers species under the genus Penaeus (previously Litopenaeus)1 and is oriented towards the production of P. vannamei2 and P. monodon. A Rationale document3 was produced as part of the ASC Shrimp Standard revision to evaluate the necessity to specifically include Penaeus stylirostris (Blue Shrimp), Penaeus merguiensis (Banana Prawn), Penaeus japonicus (Kuruma Prawn) and Penaeus ensis (Greasyback Shrimp) within the ASC Shrimp Standard. It was concluded that specific metrics for these species are not necessary and certification can remain on the basis of the metrics already contained therein for P. vannamei and P. monodon. Corresponding Metrics The ASC Shrimp Standard covers seven principles regarding legal regulations, environmentally suitable sighting and operation, community interactions, responsible operation practices, shrimp health management, stock management and resources use. -
Distribution and Abundance of Some Epibenthic Invertebrates of the Northeastern Gulf of Alaska with Notes on the Feeding Biology of Selected Species
DISTRIBUTION AND ABUNDANCE OF SOME EPIBENTHIC INVERTEBRATES OF THE NORTHEASTERN GULF OF ALASKA WITH NOTES ON THE FEEDING BIOLOGY OF SELECTED SPECIES by Howard M. Feder and Stephen C. Jewett Institute of Marine Science University of Alaska Fairbanks, Alaska 99701 Final Report Outer Continental Shelf Environmental Assessment Program Research Unit 5 August 1978 357 We thank Max Hoberg, University of Alaska, and the research group from the Northwest Fisheries Center, Seattle, Washington, for assistance aboard the MV North Pucijk. We also thank Lael Ronholt, Northwest Fisheries Center, for data on commercially important invertebrates. Dr. D. P. Abbott, of the Hopkins Marine Station, Stanford University, identified the tunicate material. We appreciate the assistance of the Marine Sorting Center and Max Hoberg of the University of Alaska for taxonomic assistance. We also thank Rosemary Hobson, Data Processing, University of Alaska, for help with coding problems and ultimate resolution of those problems. This study was funded by the Bureau of Land Management, Department of the Interior, through an interagency agreement with the National Oceanic and Atmospheric Administration, Department of Commerce, as part of the Alaska Outer Continental Shelf Environmental Assessment Program. SUMMARY OF OBJEC!CIVES, CONCLUSIONS, AND IMPLICATIONS WITH RESPECT TO OCS OIL AND GAS DEVELOPMENT The objectives of this study were to obtain (1) a qualitative and quantitative inventory of dominant epibenthic species within the study area, (2) a description of spatial distribution patterns of selected benthic invertebrate species, and (3) preliminary observations of biological interrelationships between selected segments of the benthic biota. The trawl survey was effective, and excellent spatial coverage was obtained, One hundred and thirty-three stations were successfully occupied, yielding a mean epifaunal invertebrate biomass of 2.6 g/mz.
