| Title: |
Model projections to the year 2116 of ocean acidification effects on the fishing profit, effort, and mortality of North Pacific crab stocks (snow crabs, Chionoecetes opilio; Tanner Crabs, Chionoecetes bairdi) in the Eastern Bering Sea for the OA Projections for Snow, Tanner, and Red King Crab in Alaska project using data collected from 1997-01-01 to 2016-12-31 (NCEI Accession 0248327) |
| Abstract: |
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. Stochastic projections that account for variation about the stock-recruitment relationship were undertaken for a constant F35% harvest strategy, a strategy that sets effort to maximize profit ignoring the effects of environmental variability such as ocean acidification, and the Acceptable Biological Catch control rule, which includes a reduction in fishing mortality rate when stocks are below target levels. 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 effort levels that achieve MSY and uMEY were sensitive to whether a spatial or non-spatial model was used to calculate reference points and hence how technical interactions among species were accounted for. Dynamic projections based on various management strategies indicated that adopting a uMEY target level of effort leads to some robustness to the effects of ocean acidification, although similar results can be obtained using the Acceptable Biological Catch control rule, which reduces harvest rates as biomass levels decline. 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 4 area management strategies described above for the years 2017 - 2116. |
