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 2017 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus) within several of their main spawning grounds. These pre-spawning pollock surveys covered the Shumagin Islands, Sanak Trough, and Morzhovoi and Pavlof bays (DY2017-01; 8-14 February), the Kenai Bays, Prince William Sound, and Hinchinbrook Trough and Middleton Island areas (DY2017-02; 2-9 March), and Shelikof Strait, the shelf break near Chirikof Island, and Marmot Bay (DY201703; 14-26 March).
