ne pas confondre avec "fish sexing"

"In the sea, all the operations that make it possible to manage wildlife for a ‘maximum sustainable yield’ (MSY) are far harder to do than on land, including owning fish, counting fish, sexing and aging fish, and selecting fish to catch."

et "recovery" signifie rétablissement du nombre de poissons d'une espèce menacée

Global efforts to combat overfishing are starting to turn the tide to allow some fish stocks to recover, new analysis shows. Research from an international team of scientists shows that a handful of major fisheries across the world have managed to reduce the rate at which fish are exploited.

The experts say their study offers hope that overfishing can be brought under control, but they warn that fishermen in Ireland and the North Sea are still catching too many fish to allow stocks to recover. Some 63% of assessed fish stocks worldwide still require rebuilding, the scientists report.

"Across all regions we are still seeing a troubling trend of increasing stock collapse," said Dr Boris Worm, an ecologist at Dalhousie University in Canada. "But this paper shows that our oceans are not a lost cause. The encouraging result is that exploitation rate, the ultimate driver of depletion and collapse, is decreasing in half the 10 systems we examined. This means that management in those areas is setting the stage for ecological and economic recovery. It's only a start, but it gives me hope that we have the ability to bring overfishing under control."
