Summary: | This report contains assessments of the conditions of groundfish and squid in the eastern Bering Sea and Aleutian Islands region management area. The assessments are based on single species analyses of commercial fishery and research vessel survey data available through August 1986. Estimates of maximum sustainable yields and acceptable biological catches or equilibrium yields are presented to guide management of the 1987 fishery. Table A summarizes results of these assessments. Pacific cod, Gadus macrocephalus; yellowfin sole, Limanda aspera; and other flatfish remain in excellent condition with current populations at or near observed peak levels of abundance. The abundance of walleye pollock, Theragra chalcogramma, also remains relatively high with the exploitable population consisting of older (mainly ages 5-7 year) fish than in previous years. The condition of sablefish, Anoplopoma fimbria, has improved in both the eastern Bering Sea and Aleutian Islands regions |
