This report summarizes the results of the 1991-96 National Marine Fisheries Service longline surveys of the Gulf of Alaska and eastern Aleutian Islands. Sablefish, Anoplopoma fimbria, was the principal target species, although shortspine thomyhead, Sebastolobus alascanus, rougheye rockfish, Sebastes aleutianus, and shortraker rockfish, Sebastes borealis, populations appear to have been sampled adequately to derive meaningful abundance indices. The survey area in the Gulf of Alaska extends from Islands of Four Mountains (170°W long.) eastward to Dixon Entrance (133°25'W long.) and covers the upper continental slope and selected gullies. Beginning in 1996, the eastern Aleutian Islands were surveyed from Amchitka Pass (178°58'W long.) to the western end of Umnak Island (170°12'W long.). 1997 NMFS (National Marine Fisheries Service) AFSC (Alaska Fisheries Science Center) Library Public Domain 1861
