There is now compelling scientific evidence that no-take areas -- or marine reserves -- conserve both biodiversity and fisheries, and could help replenish depleted fish stocks, according to a consensus statement signed by 160 marine-science academics from around the world. Released February 17 at the annual meeting of the American Association for the Advancement of Science (AAAS), the statement is the culmination of a three-year, international effort to advance scientific understanding of marine reserves.
"All around the world there are different experiences, but the basic message is the same: marine reserves work, and they work fast," said Jane Lubchenco (Oregon State University, USA), a past president of AAAS and a leader of the three-year effort. "It is no longer a question of whether to set aside fully protected areas in the ocean, but where to establish them."
The consensus statement recommends that marine resource managers use reserves as a "central management tool" for achieving long-term fishery and conservation benefits. It concludes that networks of reserves, rather than isolated single reserves, will be necessary to buffer against environmental variability and catastrophes.
