Abstract

Despite a growing call for ecosystem-based fishery management, most fisheries are managed independently with little attention paid to linkages such as competition for resources and predator-prey relationships. As the predator-prey modeling literature has shown, such linkages can substantially alter the outcomes of management strategies from those predicted by models naïve to these linkages. In this article, we explore the implications of a linkage between fisheries due to an artificial predator-prey relationship; the use of one harvested species as an input to the harvest technology in another primary fishery whose biological productivity is also positively affected by bait consumption. These anthropogenic, technological, and biological linkages between the fisheries alter both the open-access and rent-maximizing equilibria of the primary fishery. Furthermore, shifts in economic, technological, or biological parameters of either fishery can have significantly different impacts on the bioeconomic equilibria than those predicted by a traditional single-species model.
