This dataset contains model output data to understand the effect of ocean acidification on the snow crab and southern Tanner crab fisheries. A multi-species size-structured population dynamics model that can account for spatial structure and technical interactions between commercial fisheries was developed and applied to the snow and southern Tanner crab fisheries in the eastern Bering Sea. The model used fisheries data collected in the eastern Bering Sea crab fisheries from 1997-01-01 to 2016-12-31. Single- and four-area models led to similar fits to abundance and catch data, and provide similar estimates of time-trajectories of mature male biomass. The model is used to compute Maximum Sustainable Yield (MSY) and an upper bound on Maximum Economic Yield (uMEY). The model was used as the basis for forecasts to calculate reference points related to yield and profit under the effects of ocean acidification on snow and southern Tanner crab. These data include two data files with forecasts for each of the 1 and ...
