Description:

This report describes the distribution and abundance of three target species of the foreign and domestic trawl fisheries, walleye pollock (Theragra chalcogramma), Pacific cod (Gadus macrocephalus) and yellowfin sole (Limanda aspera) and five species prohibited to trawl fishing, king crab (Paralithodes camtschatica and P. platypus), snow (Tanner crab) (Chionoectes bairdi and C. opilio) and Pacific halibut (Hippoglossus stenolepis) in the eastern Bering Sea from 1979 through 1983. Data were obtained from research bottom trawl surveys conducted from June through September in each year by the National Marine Fisheries Service. Prohibited species are incidentally caught by bottom trawl fisheries while fishing for target species. Regulations require that prohibited species must be returned to the sea but handling mortality may cause a reduction in these species which are the targets of other fisheries. Reducing the catch of prohibited species saves the additional handling time of removal from the catch and benefits the prohibited species by reducing mortality. Therefore, it is important to know the distribution and abundance of both target and prohibited species so as to increase the benefit of the catch to all fisheries concerned.
