Marine Reserve Boosts Tuna Stocks.

Commercial fishermen always complain about reduced catches whenever marine reserves are established; they make the same complaints whenever fish quotas are introduced. This report on the BBC shows that the opposite is true.

The Papahãnaumokuãkea Marine National Monument in Hawaii, a vast marine reserve ("almost four times the size of California"), was established in 2006, and already, after only 6 years, fish stocks in neighbouring waters have increased: "catch rates for yellowfin tuna had increased by 54%, bigeye tuna by 12% and all fish species combined by 8%". This shows that establishing marine reserves works to increase fish stocks and catch sizes, and quickly.

Maybe there is hope that we can save the oceans, if we act now.
