Description:
The Alaska Fisheries Science Center (AFSC) has annually completed a bottom longline survey in Alaska since 1978. The survey samples demersal waters of the upper continental slope and is primarily designed to assess sablefish (Anoplopoma fimbria), although several other groundfish species are caught in significant numbers. In 2017, the 40th annual longline survey sampled stations in the Bering Sea and the Gulf of Alaska. The primary objectives of the survey were to determine the relative abundance of sablefish and other groundfish species, collect sablefish otoliths to determine the age composition of the population, and to tag and release a subsample of selected groundfish to determine movement patterns.
