Climate Impacts on Sawning Stock-recruitment Relationships from Multi- and Single-species Stock Assessment Models (Figs. 1 and 2)
Figure 1. Recruitment estimates from the multi-species stock assessment model (black lines) and stock-recruitment regression model estimates for recruitment functions without zooplankton covariates (gray) and with zooplankton covariates (red).
Figure 2. Projected spawning stock biomass for walleye pollock predicted from single (a) and multi-species (b) modes of MSM under various recruitment relationships and no harvest (“SSB unfished”; dashed line) or harvest that yields 40% of SSB on average during the last 5 years (2045-50) of the projection (B40%; solid line).
