FISHERIES – Effects of marine protected areas on local fisheries: evidence from empirical studies

Marine fisheries throughout the world are in serious decline due to overharvesting (National Research Council, 2001), and management for sustainable fisheries requires effective tactics for limiting exploitation rates. Limitations based on annual stock assessments and total allowable catches calculated from these assessments can be dangerous, and marine protected areas (MPAs) are one tool to limit exploitation rates directly even when total stock size is highly uncertain (Walters, 2000).
