Aspects of the Life History of Hornyhead Turbot, Pleuronichthys Verticalis, Off Southern California
Aspects of the Life History of Hornyhead Turbot, Pleuronichthys verticalis, off Southern California he hornyhead turbot T(Pleuronichthys verticalis) is a common resident flatfish on the mainland shelf from Magdalena Bay, Baja Califor- nia, Mexico to Point Reyes, California (Miller and Lea 1972). They are randomly distributed over the bottom at a density of about one fish per 130 m2 and lie partially buried in the sediment (Luckinbill 1969). Hornyhead turbot feed primarily on sedentary, tube-dwelling polychaetes (Luckinbill 1969, Allen 1982, Cross et al. 1985).

Greenland Turbot Assessment
6HFWLRQ STOCK ASSESSMENT OF GREENLAND TURBOT James N. Ianelli, Thomas K. Wilderbuer, and Terrance M. Sample 6XPPDU\ Changes to this year’s assessment in the past year include: 1. new summary estimates of retained and discarded Greenland turbot by different target fisheries, 2. update the estimated catch levels by gear type in recent years, and 3. new length frequency and biomass data from the 1998 NMFS eastern Bering Sea shelf survey. Conditions do not appear to have changed substantively over the past several years. For example, the abundance of Greenland turbot from the eastern Bering Sea (EBS) shelf-trawl survey has found only spotty quantities with very few small fish that were common in the late 1970s and early 1980s. The majority of the catch has shifted to longline gear in recent years. The assessment model analysis was similar to last year but with a slightly higher estimated overall abundance. We attribute this to a slightly improved fit to the longline survey data trend. The target stock size (B40%, female spawning biomass) is estimated at about 139,000 tons while the projected 1999 spawning biomass is about 110,000 tons. The adjusted yield projection from F40% computations is estimated at 20,000 tons for 1999, and increase of 5,000 from last year’s ABC. Given the continued downward abundance trend and no sign of recruitment to the EBS shelf, extra caution is warranted. We therefore recommend that the ABC be set to 15,000 tons (same value as last year). As additional survey information become available and signs of recruitment (perhaps from areas other than the shelf) are apparent, then we believe that the full ABC or increases in harvest may be appropriate for this species. -

Variability in Trawl Survey Catches of Pacific Ocean Perch, Shortraker Rockfish, and Rougheye Rockfish in the Gulf of Alaska David M
Biology, Assessment, and Management of North Pacific Rockfishes 411 Alaska Sea Grant College Program • AK-SG-07-01, 2007 Variability in Trawl Survey Catches of Pacific Ocean Perch, Shortraker Rockfish, and Rougheye Rockfish in the Gulf of Alaska David M. Clausen and Jeffrey T. Fujioka National Marine Fisheries Service, Auke Bay Laboratory, Juneau, Alaska Abstract Little information is available on the comparative variability of Pacific ocean perch, shortraker rockfish, and rougheye rockfish catches in Alaska trawl surveys. In this study, data were first examined for these three species from three localized experimental bottom trawl surveys in the Gulf of Alaska in 1993, 1998, and 1999 to compare the variability of catch rates for each species. When catch rates were analyzed within favorable fishing areas for each species, the coefficients of variation for Pacific ocean perch were approximately 2.5 to 3 times greater than those of shortraker or rougheye rockfish, indicating that the latter two species are much more even in their distribution. To provide a broader comparison of variability, catch rates of the three species were also examined from seven large-scale bottom trawl surveys conducted in the Gulf of Alaska from 1984 to 2001. Using geographic information systems software, subsets of the hauls in these surveys were selected in what were determined to be favorable fishing areas for either Pacific ocean perch or for shortraker and rougheye rockfish. Analysis of the species’ catch rates in these hauls indicated results that were very simi- lar to those of the experimental trawl surveys; the variability of Pacific ocean perch was 2.1-2.3 times greater than that for either shortraker or rougheye rockfish. -
