 The Gustavus economy is strongly linked to the surrounding natural resources; tourism and commercial fishing are mainstays.However, the importance of commercial fishing is in decline, as the Dungeness crab fishery in Glacier Bay National Park was closed in the early 2000s and the fishing for Dungeness outside of the national park has become poor.Salmon and halibut remain as the primary catch of the commercial fishing done out of Gustavus.
