Rebuilding Strategies for Multispecies Fisheries: A Stylized Bioeconomic Model

In this paper, we investigate the bioeconomicimpacts of selected rebuilding strategies in amultispecies fishery. Using a stylizedbioeconomic model, we identify the conditionsunder which modifying the species selectivityproperties of the gear would contribute to therebuilding of over-exploited stocks. We examinethe cases where the stocks are biologicallyindependent and interdependent. Our analysissuggests that the success of the rebuildingprocess not only depends on the nature of thegear modifications but also on the biologicaland economic characteristics of the fishery.
