Figure 8. Outputs of the simulations for the first scenario (change of total fishing effort without spatial constraints).

Convex hulls are used to represent the set of values of B₂₀₁₁ (Predicted biomass at year 2011) versus G₂₀₁₀ (Gains for year 2010) corresponding to the optimized patterns returned by each run, with red dashed lines and red points represent G₂₀₁₀ and B₂₀₁₁ for the real (observed) pattern of fishing effort in 2010. The bottom x axis reports the absolute values for B₂₀₁₁, while the top x axis shows the same values as differential percentage from the reference value (B₂₀₁₁ for the observed pattern of fishing effort at year 2010). A yellow-red color scale is used to emphasize the progressive increase of total effort from 70% to 130% of the real (observed) value at year 2010.
