The ninth biennial groundfish assessment survey of the Aleutian Islands region was conducted during the summer of 2018 by the Alaska Fisheries Science Center’s (AFSC) Resource Assessment and Conservation Engineering Division’s Groundfish Assessment Program (RACE-GAP). This effort constitutes the fifteenth in the full series dating from 1980. The survey area covered the continental shelf and upper continental slope to 500 m in the Aleutian Archipelago from Islands of Four Mountains (170° W long.) to Stalemate Bank (170° E long.), including Petrel Bank and Petrel Spur (180° long.), and the northern side of the Aleutian Islands between Unimak Pass (165° W long.) and the Islands of Four Mountains. The survey was conducted aboard two chartered trawlers, the FV Ocean Explorer and FV Sea Storm.
