Ocean fisheries management: implications for the volume and quality offish supply

摘要

This paper considers the probable impact of improved fisheries management on the volume and quality of fish supply. It is shown that the transition from a rent dissipation equilibrium (where most open access fisheries find themselves) to an economically efficient equilibrium may just as easily entail a decrease as an increase in the volume of harvest. Indeed, given the current level of the world's fish stacks, it appears unlikely that the current trend toward economically efficient fisheries management regimes will result in a significant increase in the worldwide supply of marine catches. Therefore, it seems that a sustained increase in the future volume of fish supply must continue to come from fish farming. The movement toward more efficient fisheries management regimes is, on the other hand, Likely to substantially enhance the quality of landed catch. Due to fish stock and fishing capital dynamics, however, this effect is likely to be stronger in the short rather than the long run.
