Movement Patterns of Black Rockfish (Sebastes Melanops)
Biology, Assessment, and Management of North Pacific Rockfishes 39 Alaska Sea Grant College Program • AK-SG-07-01, 2007 Movement Patterns of Black Rockfish Sebastes( melanops) in Oregon Coastal Waters Steven J. Parker, Polly S. Rankin, Jean M. Olson, and Robert W. Hannah Oregon Department of Fish and Wildlife, Hatfield Marine Science Center, Newport, Oregon Abstract We studied the movement patterns of black rockfish Sebastes( mela- nops) in Oregon coastal waters to estimate home range over daily to annual time scales, determine if females relocate during the reproduc- tive season, and evaluate the influence of environmental variation on movement. We moored 18 acoustic receivers in a 3 × 5 km array south of Newport, Oregon, at depths from 9 to 40 m. We then surgically implanted 42 black rockfish (34-48 cm total length [TL]) with coded, pressure transmitters having an approximate lifespan of 6 months. Fish were tagged in August (n = 6), September (n = 13), October (n = 7), and February (n = 8 depth and 8 non-depth). Fish were temporarily absent from the monitored area for short periods (usually <7 days) indicating limited travel outside the monitored area. Seven fish left the area per- manently. During one full year of monitoring, home ranges were rela- tively small (55±9 ha) and did not vary seasonally. Absences of females >39 cm (likely mature) from the array were longer in duration than for mature males, especially during the reproductive season (November, January, and February), but both sexes had the longest absences dur- ing April through July. These data indicate that black rockfish in open coastal waters live in a very restricted area for long periods as adults, but may relocate periodically. -
Black Rockfish, Sebastes Melanops
12 Black Rockfish, Sebastes melanops Black rockfish, Sebastes melanops. Photo credit: Edgar Roberts. History of the Fishery The black rockfish, Sebastes melanops, is an important recreational and commercial species in the nearshore rockfish group, particularly in areas north of San Francisco. Black rockfish are an important commercial nearshore species in California, specifically in the Crescent City port complex; 74 percent, by weight, of all black rockfish were landed there over the past decade. Black rockfish are recorded specifically in the market category “black rockfish” on landing receipts, but some black rockfish may also be recorded in other market categories such as “blue rockfish” or “rockfish, group black/blue.” Conversely, due to similarity in appearance, blue rockfish are sometimes recorded as “black rockfish” on landing receipts. Black rockfish are part of the deeper nearshore species complex composed of black, blue, brown, calico, copper, olive, quillback and treefish rockfishes. Since 2003, a Deeper Nearshore Species Fishery Permit (DNSFP) has been required to take deeper nearshore species. Black rockfish are caught primarily using hook and line gears, with marginal amounts caught in traps. In the past, black rockfish were also caught using trawl gear or gill nets. Since 1998, commercial landings of black rockfish made up approximately 52 percent of deeper nearshore rockfish species landings by weight. Commercial landings of black rockfish fluctuated between 110,603 pounds (50 metric tons) and 229,640 pounds (104 metric tons) from 1998 to 2008 (Figure 12-1) but showed no distinct trend. Many of the decreases in annual landings correspond to changes in management structure, as discussed below in Management Considerations. -

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). -

Vii Fishery-At-A-Glance: California Sheephead
Fishery-at-a-Glance: California Sheephead (Sheephead) Scientific Name: Semicossyphus pulcher Range: Sheephead range from the Gulf of California to Monterey Bay, California, although they are uncommon north of Point Conception. Habitat: Both adult and juvenile Sheephead primarily reside in kelp forest and rocky reef habitats. Size (length and weight): Male Sheephead can grow up to a length of three feet (91 centimeters) and weigh over 36 pounds (16 kilograms). Life span: The oldest Sheephead ever reported was a male at 53 years. Reproduction: As protogynous hermaphrodites, all Sheephead begin life as females, and older, larger females can develop into males. They are batch spawners, releasing eggs and sperm into the water column multiple times during their spawning season from July to September. Prey: Sheephead are generalist carnivores whose diet shifts throughout their growth. Juveniles primarily consume small invertebrates like tube-dwelling polychaetes, bryozoans and brittle stars, and adults shift to consuming larger mobile invertebrates like sea urchins. Predators: Predators of adult Sheephead include Giant Sea Bass, Soupfin Sharks and California Sea Lions. Fishery: Sheephead support both a popular recreational and a commercial fishery in southern California. Area fished: Sheephead are fished primarily south of Point Conception (Santa Barbara County) in nearshore waters around the offshore islands and along the mainland shore over rocky reefs and in kelp forests. Fishing season: Recreational anglers can fish for Sheephead from March 1through December 31 onboard boats south of Point Conception and May 1 through December 31 between Pigeon Point and Point Conception. Recreational divers and shore-based anglers can fish for Sheephead year round. -
DESCRIBING DUSKY ROCKFISH (Sebastes Ci/Iatus) HABITAT in the GULF of ALASKA USING HISTORICAL DATA
DESCRIBING DUSKY ROCKFISH (Sebastes ci/iatus) HABITAT IN THE GULF OF ALASKA USING HISTORICAL DATA A University Thesis Presented to the Faculty of California State University, Hayward In Partial Fulfillment of the Requirements for the Degree Master of Science in Marine Sciences by Rebecca Francesca Reuter March, 1999 Abstract Aspects of dusky rockfish (Sebastes ciliatus) habitat in the Gulf of Alaska are described using historical data sources. In this study Alaskan groundfish fishery data collected by observers between 1990-96 and research survey data collected from three triennial surveys conducted by the National Marine Fisheries Service were used. These two data sets provide data that are essential in the preliminary description of the habitat and ecology of S. ciliatus. Analyses using techniques such as geographic information systems (GIS) to describe the geographic distribution and hierarchical cluster analysis to describe rockfish species associations with S. ciliatus provide results that describe some of the parameters of their essential habitat. S. cilia/us occur in great abundance over localized areas throughout the Gulf of Alaska. Results of analyses using fishery data indicate that fishermen findS. ciliatus in abundance near mouths of submarine gullies/canyons and at deep banks. Analysis of survey data show that areas of S. ciliatus habitat are not adequately sampled, but they do support the results of the fishery data by showing that S. ciliatus do not have a dispersed distribution. The depth range where most adultS. ciliatus aggregations occur are located at I 00 - 200 m. Tllis information may be used to suggest a management scheme that calculates localized quotas for these habitat locations. -
