Fisheries and Fish Habitat

Science Center Objects

The estuarine habitat of the Delta is critical to the production of salmon, which supports recreational, commercial, and subsistence fishing. The combination of shaded pools, shallow reaches, and a rich prey population provide excellent feeding grounds for juvenile fish. Fishing also holds great importance in the cultural practices of the Nisqually Tribe.

We will construct a bioeconomic model that incorporates coho salmon population dynamics, fishing behavior, and the economic value of treaty commercial coho salmon fishing in the Nisqually River Delta to derive an ecosystem service value for fishing. Using projections for habitat change from our habitat/elevation models, we can also estimate potential changes in suitable Chinook salmon habitat across sea level rise scenarios.
