From: Modelling ocean acidification effects with life stage-specific responses alters spatiotemporal patterns of catch and revenues of American lobster, Homarus americanus

Figure 4

The effect of implementing different scenarios of fishing size limits on: (a) maximum catch potential based on different catch proportions of canner lobsters, and (b) landed value potential with different price ratios of market to canner lobsters. Values are the change weighted by tonnage of the different priced lobster sizes by end of twenty-first century (2091–2100) under a high climate change scenario (RCP 8.5), relative to 2010 for American lobster biomass. Proportion of canners in catch were kept constant at 0.2 (the current value) for the analysis in panel b, except for when size limits were > 1 lb (thus no canners in catch). Points represent multi-model means from simulations from three earth system models and error bars represent the minimum and maximum of the three outputs. Parameter values were used from our null model (Table 2): climate change scenario = RCP 8.5; OA mortality effect size = 15%; OA effects on life stage = all; fishing pressure = MSY.
