Putting No-Take Marine Reserves in Perspective

By Mark Tupper, University of Guam

Many scientists agree that tropical fisheries in developing island nations, such as St. Lucia, stand to gain the most from no-take marine reserves.  Many of these island fisheries are seriously overexploited and have little or no management of their reef fish stocks. In such cases, where no-take marine reserves are established they serve as the primary (in some cases sole) controls of catch and effort.  It seems obvious that any management regime will produce increased yields over no management at all, and for developing tropical nations with several hundred or more species of reef fish, no-take marine reserves might be much easier to enforce than a complex set of catch limits, size limits, and gear restrictions.  However, the St. Lucia example is specific to coral reef fisheries and does not prove the global utility of no-take marine reserves to fisheries.
