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. -

Do Some Atlantic Bluefin Tuna Skip Spawning?
SCRS/2006/088 Col. Vol. Sci. Pap. ICCAT, 60(4): 1141-1153 (2007) DO SOME ATLANTIC BLUEFIN TUNA SKIP SPAWNING? David H. Secor1 SUMMARY During the spawning season for Atlantic bluefin tuna, some adults occur outside known spawning centers, suggesting either unknown spawning regions, or fundamental errors in our current understanding of bluefin tuna reproductive schedules. Based upon recent scientific perspectives, skipped spawning (delayed maturation and non-annual spawning) is possibly prevalent in moderately long-lived marine species like bluefin tuna. In principle, skipped spawning represents a trade-off between current and future reproduction. By foregoing reproduction, an individual can incur survival and growth benefits that accrue in deferred reproduction. Across a range of species, skipped reproduction was positively correlated with longevity, but for non-sturgeon species, adults spawned at intervals at least once every two years. A range of types of skipped spawning (constant, younger, older, event skipping; and delays in first maturation) was modeled for the western Atlantic bluefin tuna population to test for their effects on the egg-production-per-recruit biological reference point (stipulated at 20% and 40%). With the exception of extreme delays in maturation, skipped spawning had relatively small effect in depressing fishing mortality (F) threshold values. This was particularly true in comparison to scenarios of a juvenile fishery (ages 4-7), which substantially depressed threshold F values. Indeed, recent F estimates for 1990-2002 western Atlantic bluefin tuna stock assessments were in excess of threshold F values when juvenile size classes were exploited. If western bluefin tuna are currently maturing at an older age than is currently assessed (i.e., 10 v. -

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.

Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications
Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications Chase Martin Center for Marine Biodiversity and Conservation Scripps Institution of Oceanography University of California San Diego Abstract Various species of Octopodidae are commonly found in seafood markets throughout Southern California. Most of the octopus available for purchase is imported, with the majority of imports coming from various Asian nations. Despite the diversity of global octopus species, products are most commonly labeled as simply “octopus,” with some distinctions being made in size, e.g., “baby” or “little octopus.” In efforts to characterize species diversity, this study genetically tested 59 octopus samples from a variety of seafood markets in Los Angeles, Orange, and San Diego Counties. Universal 16S rRNA primers (ref) and CO1 primers developed by Folmer et al. (1994) were used for PCR amplification and sequencing of mtDNA. In all, 105 sequences were acquired. Seven species were identified with some confidence. Amphioctopus aegina was the most prevalent species, while two additional species were undetermined. Little available data exists pertaining to octopus fisheries of the countries of production of the samples. Most available information on octopus fisheries pertains to those of Mediterranean and North African nations, and identifies the Octopus vulgaris as the fished species. Characterizing octopus diversity in Southern California seafood markets and assessing labeling and countries of production provides the necessary first step for assessing the possible management implications of these fisheries and seafood supply chain logistics for this group of cephalopods. Introduction Octopuses are exclusively marine cephalopod mollusks that form the order Octopoda. -
