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 conducted acoustic-trawl (AT) stock assessment surveys in the Gulf of Alaska (GOA) during late winter and early spring 2018 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus) at several of their main spawning grounds. These pre-spawning pollock surveys covered the Shumagin Islands, Sanak Trough, Morzhovoi and Pavlof bays (DY2018-01; 5-15 February), and Shelikof Strait and Marmot Bay (DY2018-03; 12-23 March). The Shumagin Islands area has been surveyed annually in winter since 2001 (except in 2004 and 2011), as well as in 1994, 1995, and 1996. This survey has also frequently included Sanak Trough, Morzhovoi Bay, and Pavlof Bay since 2002. The Shelikof Strait area has been surveyed annually in winter since 1981 (except in 1982, 1999, and 2011), and since 1989 this survey has often included Marmot Bay.
