Condition of the groundfish resources of the eastern Bering Sea and Aleutian Island region in 1981. (Document submitted to the annual meeting
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 max...
