Abstract or Summary
  • The individual size of fish as a proxy for life-history traits and market value displays an important, yet in bioeconomic modelling often ignored biological and economic parameter. This raises the question if and to what extent the consideration of a pricing related to the individual size influences optimal harvest strategies. We demonstrate here that the magnitude of size-dependency in the pricing clearly causes a quantitative impact on the outcome of optimizing the harvest strategy. Resulting is not only a shift regarding the potentially achieved revenues, but mainly a correlation regarding the optimal fishing pattern and the catch weights. The observed qualitative tendency towards a reduction in the fishing mortality simultaneously yielding higher catch weights with increasing size-dependent price effects can be generalized and is insensitive of additional economic factors like the discount rate or demand functions. These findings suggest that size-dependent pricing has a certain impact on the harvest strategy if one is aiming for maximum economic yield (MEY) and hence it should be more often accounted for in bioeconomic modelling.
