Echo integration-trawl (EIT) surveys were conducted in the Gulf of Alaska (GOA) during the summer in 2003 and 2005 to determine the feasibility of using acoustic survey methods to estimate walleye pollock (Theragra chalcogramma) distribution and abundance. The 2003 survey was conducted aboard the NOAA ship Miller Freeman from 4 June to 16 July and covered the GOA shelf and shelfbreak from the Shumagin Islands to Prince William Sound. The 2005 survey was conducted aboard the NOAA ship Oscar Dyson from 30 June to 30 July and covered portions of the GOA shelf and shelfbreak from the Islands of Four Mountains to south of Prince William Sound. The densest walleye pollock aggregations in 2003 were detected in the vicinity of Kodiak Island, which included Barnabas and Chiniak troughs, the Shelikof Strait sea valley, Marmot and Alitak bays, and on the shelf east of Kodiak Island. Walleye pollock were also detected in the near-shore basins of deeper water off Renshaw Point in the Shumagin Islands and off Nakchamik Island. In 2005, the densest pollock aggregations were detected in the vicinity of Kodiak Island in northern Barnabas and Chiniak troughs, within Shelikof Strait proper, and along the shelf break between Chirikof Island and Barnabas Trough. Results show that pollock can be successfully assessed using EIT survey methods during summer in the GOA. Of other fish species encountered, capelin (Mallotus villosus) and rockfish (Sebastes sp.) have the most potential to be assessed using EIT survey methodology.
