Scientists from the Midwater Assessment and Conservation Engineering (MACE) Program of the Alaska Fisheries Science Center's (AFSC) Resource Assessment and Conservation Engineering (RACE) Division routinely conduct echo integration-trawl (EIT) stock assessment surveys in the Gulf of Alaska (GOA) during late winter and early spring to estimate the distribution and abundance of walleye pollock (Theragra chalcogramma). Surveys were conducted in the Shumagin Islands area in 1994-96, 2001-03, and 2005-07 and along the GOA continental shelf break east of Chirikof Island to Barnabas Trench in 2002-07. This report presents the distribution and abundance of walleye pollock for surveys conducted in the Shumagins during February and March 2009.
