Description:

"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). Most of this effort has been focused on the Shelikof Strait area, which has been surveyed annually since 1980, except in 1982 and 1999. Surveys were also conducted in the Shumagin Islands area in 1994-96, 2001-03, and 2005-06 and along the GOA shelf break east of Chirikof Island in 2002-06. This report presents the distribution and abundance of walleye pollock for surveys conducted in the GOA during February and March 2007"--Introduction.
