Equivalence in yield from marine reserves and traditional fisheries management

Marine reserves have been proposed as a remedy for overfishing and declinin g marine biodiversity, but concern that reserves would inherently reduce yi elds has impeded their implementation. It was found that management of fish eries through reserves and management through effort control produce identi cal yields under a reasonable set of simplifying assumptions corresponding to a broad range of biological conditions. Indeed, for populations with sed entary adults (invertebrates and reef fishes), reserves have important adva ntages for sustainability, making marine reserves the preferred management approach.
