New research points to a better way of protecting fish stocks EVERYBODY knows that global fish stocks are heading for collapse. That is why governments try to limit the amount of fish taken out of the sea. But recent research suggests that the world is going about regulating fishing the wrong way—that fish stocks would fare better if efforts were made to protect entire ecosystems rather than individual species.
There are plenty of data to prove the importance of diversity on dry land. Until recently, however, there was little evidence that the same was the case in the oceans, which make up 90% of the biosphere, and on which a billion people rely for their livelihoods.
In order to establish whether diversity matters in the sea as well as on land, 11 marine biologists, along with three economists, have spent the past three years crunching all the numbers they could lay their hands on.

The results of their comprehensive analysis have been published in Science.
