Privatization Prevents Collapse of Fish Stocks, Global Analysis Shows

[Invité jabial]

Two years ago, a team of researchers took a broad look at the world's commercial fisheries and predicted that excessive harvesting would cause them all to collapse by 2048. Now, three other scientists have taken an equally broad look at how fisheries are managed and come up with a more hopeful view.

On page 1678, the trio--Christopher Costello and Steven Gaines of the University of California, Santa Barbara, and John Lynham, now at the University of Hawaii, Manoa--shows that stocks are much less likely to collapse if fishers own rights to fish them, called catch shares. If implemented worldwide, they say, this kind of market-based management could reverse a destructive global trend. Says David Festa of the Environmental Defense Fund in San Francisco, California, "This gives definitive, concrete proof that this tool does end overfishing."
