Modeled time-trajectories to the year 2100 for Eastern Bering Sea snow, southern Tanner, and red king crab of the fully-selected fishing mortality at which total catch and profit are maximized and the catch by species/total profit, expressed relative to the values for a reference period from 2020-01-01 to 2022-04-23 for the OA Projections for Snow, Tanner, and Red King Crab in Alaska Project (NCEI Accession 0253126)

We developed a framework that examines the consequences of temporal changes in temperature and ocean pH on yield and profit of multiple interacting stocks including eastern Bering Sea (EBS) snow, southern Tanner, and red king crab. Our analyses integrated experimental work on the effects of temperature and ocean pH on growth and survival of larval and juvenile crab and monitoring data from surveys, fishery landings, and at-sea observer programs. A post-recruitment model was used to compute the fishing mortality rates at which catch and profit are maximized for each year from 2020 to 2100 given the environmental conditions (ocean pH, bottom temperature and surface temperature) in the year concerned, and the implications of unintended bycatch in directed fisheries. The impacts of future changes in temperature and ocean pH on early life history have effects that differ markedly among stocks, being most pessimistic for Bristol Bay red king crab and most optimistic for EBS snow crab
