Description:

The results of the first comprehensive resource assessment survey of groundfish stocks in the Aleutian Island region is presented. During July- November 1980, two U.S. fishing vessels chartered by the Northwest and Alaska Fisheries Center of the National Marine Fisheries Service (NMFS) and a large Japanese stern trawler chartered by the Japan Fisheries Agency (JFA) successfully completed 319 demersal trawl sampling stations. Species encountered in highest abundance include walleye pollock, Theragra chalcogramma; giant grenadier, Albatrossia pectoralis; Pacific ocean perch, Sebastes alutus;Pacific cod, Gadus macrocephalus; and Atka mackerel, Pleurogrammus monopterygius. Information on the principal species occurring in the catches includes biomass estimates, catch rates, distribution and abundance, individual haul and catch listings, and size composition. Age composition is also presented for fourspecies where age information is available.
