Economically Optimal Marine Reserves Without Spatial Heterogeneity in a Simple Two-Patch Model
نویسندگان
چکیده
Bioeconomic analyses of spatial fishery models have established that marine reserves can be economically optimal (i.e., maximize sustainable profit) when there is some type of spatial 2 heterogeneity in the system. Analyses of spatially continuous models and models with more than two discrete patches have also demonstrated that marine reserves can be economically 4 optimal even when the system is spatially homogeneous. In this note we analyze a spatially homogeneous two-patch model and show that marine reserves can be economically optimal 6 in this case as well. The model we study includes the possibility that fishing can damage habitat. In this model, marine reserves are necessary to maximize sustainable profit when 8 dispersal between the patches is sufficiently high and habitat is especially vulnerable to damage. 10

When are no-take zones an economically optimal fishery management strategy?
Discussions on the use of marine reserves (no-take zones) and, more generally, spatial management of fisheries are, for the most part, devoid of analyses that consider the ecological and economic effects simultaneously. To fill this gap, we develop a two-patch ecological-economic model to investigate the effects of spatial management on fishery profits. Because the fishery effects of spatial ma...
متن کاملUntangling Natural Seascape Variation from Marine Reserve Effects Using a Landscape Approach
Distinguishing management effects from the inherent variability in a system is a key consideration in assessing reserve efficacy. Here, we demonstrate how seascape heterogeneity, defined as the spatial configuration and composition of coral reef habitats, can mask our ability to discern reserve effects. We then test the application of a landscape approach, utilizing advances in benthic habitat ...
متن کاملIncluding Species Interactions in the Design and Evaluation of Marine Reserves: Some Insights from a Predator-prey Model
Conservation of marine species through fisheries management and no-take marine reserves have focused primarily on single species, but such protection may influence the target speciesʼ predators, prey, competitors, or mutualists. Conversely, successful protection may depend on responses of these other species. Empirical data and previous theory indicate that fisheries status and life-history att...
متن کاملMarine reserves with ecological uncertainty.
To help manage the fluctuations inherent in fish populations scientists have argued for both an ecosystem approach to management and the greater use of marine reserves. Support for reserves includes empirical evidence that they can raise the spawning biomass and mean size of exploited populations, increase the abundance of species and, relative to reference sites, raise population density, biom...
متن کاملSpatial structure induced by marine reserves shapes population responses to catastrophes in mathematical models.
Catastrophic events such as oil spills, hypoxia, disease, and major predation events occur in marine ecosystems and affect fish populations. Previous evaluations of the performance of spatial management alternatives have not considered catastrophic events. We investigate the effects of local and global catastrophic events on populations managed with and without no-take marine reserves and with ...
