• Lingcod are large, predatory fish that occur on the west coast of the United States. In Prince William Sound, they are a common target for sport fishermen because of their aggressive behavior and impressive size (up to 150 cm in length). However, in addition to their popularity among sportfishermen and cooks, they are vulnerable to commercial fisheries that occur in the offshore waters in the Northern Gulf of Alaska. Ms. Berghaus' research focus lies on the stock status of this bottom-dwelling fish in Prince William Sound. This project will ideally lead to a better understanding of lingcod age and length at maturity, fecundity, sex-based length- and age-structure, mortality and potentially movement within the Prince William Sound management area. The project is highly involved with the Alaska Department of Fish and Game and the Prince William Sound Charter Boat Association.
