Rebuilding strategies for multispecies fisheries: A stylized bioeconomic model

In this paper, we investigate the bioeconomic impacts of selected rebuilding strategies in a multispecies fishery. Using a stylized bioeconomic model, we identify the conditions under which modifying the species selectivity properties of the gear would contribute to the rebuilding of over-exploited stocks. We examine the cases where the stocks are biologically independent and interdependent. Our analysis suggests that the success of the rebuilding process not only depends on the nature of the gear modifications but also on the biological and economic characteristics of the fishery.
