There are plenty of fish in the sea, but not 50 years from now

Literally speaking, there are really plenty of fish in the sea. But a team of researchers have found out that 50 years from now, there will be virtually nothing left to fish in the seas.

A major scientific study published in the journal Science revealed that if the current trends of marine exploitation continue, then fishery decline will happen -- closely tied to a much greater loss of marine biodiversity. The research was composed of scientists from different institutions in Europe and the Americas.

Research leader Boris Worm of Dalhousie University in Canada told BBC News that the stocks have collapsed to nearly one-thirds of sea fisheries. Another scientist, Steve Palumbi of the Stanford University in California, warned about the half century left for the seafood: "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."

Catch records from the season revealed there was a decline compared to the past years. In 2003, 29% of open sea fisheries were in a state of collapse, where fishermens' yield declined to 10%. A part of the study also showed areas where fishing is heavily restricted brought back the biodiversity and restored the fish population.

The research implicated of the protection of the oceans, and the good management of marine parks and fisheries. The concept of protecting fish stocks by protecting biodiversity does make sense, said Carl Gustaf Lundin, head of the global marine programme at IUCN, the World Conservation Union. "We should protect biodiversity, and it does pay off even in simple monetary terms through fisheries yield."
