Fish stocks double near marine reserves - DNA tells the story
New Scientist Article: DNA suggests marine reserves boost commercial fishing 24 May 2012 byMichael Slezak
If you protect fish, there will be more of them to catch. That's the reasoning conservationists have long used to persuade commercial fisheries of the benefits of marine reserves. Now they may have DNA confirmation.
Now, with the use of new DNA profiling techniques, scientists have shown that by devoting less than a third of an area to a marine reserve network, you can double the number of juvenile fish that settle in the rest of the area. (Current Biology, DOI: 10.1016/j.cub.2012.04.008)
