'Only 50 years left' for sea fish'

Natural protection
There will be virtually nothing left to fish from the seas by the middle of the century if current trends continue, according to a major scientific study. Stocks have collapsed in nearly one-third of sea fisheries, and the rate of decline is accelerating.
Writing in the journal Science, the international team of researchers says fishery decline is closely tied to a broader loss of marine biodiversity.
But a greater use of protected areas could safeguard existing stocks. "The way we use the oceans is that we hope and assume there will always be another species to exploit after we've completely gone through the last one," said research leader Boris Worm, from Dalhousie University in Canada.

This century is the last century of wild seafood

Should fish be off the menu?
Send us your comments "What we're highlighting is there is a finite number of stocks; we have gone through one-third, and we are going to get through the rest," he told the BBC News website.

Steve Palumbi, from Stanford University in California, one of the other scientists on the project, added: "Unless we fundamentally change the way we manage all the ocean species together, as working ecosystems, then this century is the last century of wild seafood."

Spanning the seas
This is a vast piece of research, incorporating scientists from many institutions in Europe and the Americas, and drawing on four distinctly different kinds of data.
