What are we protecting? Fisher behavior and the unintended consequences of spatial closures as a fishery management tool
Spatial closures like marine protected areas (MPAs) are prominent tools for ecosystem‐based management in fisheries. However, the adaptive behavior of fishermen, the apex predator in the ecosystem, to MPAs may upset the balance of fishing impacts across species. While ecosystem‐based management (EBM...
