Article from the NYTimes that discusses the controversial plans to expand protected areas inside the Florida Keys National Marine Sanctuary.

Closing the 10,522 acres to fishing — a section of the park that the federal government controls alone — is one of several options on the table, Mr. Carlstrom said. It has been shown, in some cases, to be an effective and quick way to replenish fish stocks, scientists said. The larger that a fish is allowed to grow, the more eggs that are released. In Dry Tortugas National Park, off Key West, this approach has helped fish rebound not just in the reserve but also beyond it, the scientists added.
