The Alaska Department of Fish and Game conducted bottom trawl surveys for crabs and groundfishes in Cook Inlet and Prince William Sound from 1989 to 2018. The trawl surveys superseded earlier pot surveys as the primary assessment of Tanner and red king crab abundance. Three areas were surveyed either annually or biennialy: Kachemak Bay (1989–2018), Kamishak Bay (1990–2012), and Prince William Sound (1990–2018).
