Abstract or Summary
  • The lack of property rights in fisheries is a well-known source of undesirable outcomes in terms of sustainability and profitability for fisheries. Both Territorial User Fishing Rights (TURF) and Marine Protected Areas (MPA) have been proposed as a tool for managing coastal fisheries, recovering stocks and improving fishing yields; it has been well argued that proper sizing and network design can lead to significant improvements from open access (OA) and over fishing situations. In this work, we study the implications of spatial management for an interconnected marine system in Valdivia, Chile. We test several spatial strategies and look at 1) Competitive and 2) Cooperative management scenarios at each section. We found that establishing MPAs in the system decreases inefficiencies caused by competition from individually managed TURFs, and that eliminating open access can generate significant gains as well in both competitive and cooperative schemes. We test these results in a wide range of movement scenarios to establish the best strategies for the system, given the diversity of species that could be relevant in a TURF-NTZ network such as the one in Valdivia.
