A dynamic computable general equilibrium (CGE) model is linked to a bioeconomic model for the Bristol Bay red king crab (BBRKC) fishery to analyze regional economic impacts of ocean acidification (OA)-induced changes in fishery yields. Yield projections based on two alternative forms (linear versus nonlinear) of OA effects on the survival of juvenile BBRKC are compared to a baseline without OA effects. Results demonstrate considerable uncertainty in yields, and show that economic impacts are sensitive to the form of OA effects, and to changes in the world price of BBRKC (Q22, Q54, Q57, R13).
