A major scientific study has concluded that there will be no fish left in the oceans in another 50 years, if the current trend of overfishing continues. Fish stocks have fallen in over 30% of sea fisheries and the rate of decline is accelerating with time. The study, which appears in journal Science, calls for a greater use of protected areas to safeguard the existing fish stocks. Steve Palumbi, one of the researchers of the study, from Stanford University in California, said that this century will be the last one for wild seafood, unless we develop efficient ways to manage all ocean species together. Boris Worm, the lead researcher of the study, from Dalhousie University in Canada said that the current trend of fishing hopes and assumes that there will always be another ocean species to exploit, if the current one goes extinct because of overfishing or loss of habitat.

The research also found that reduction in biodiversity is affecting the population and robustness of local fish stocks, endorsing the results of many large-scale studies, which concluded that loss of biodiversity is driving the declines in fish stocks. However, data from protected areas and areas where fishing is heavily restricted show that biodiversity is bouncing back in such regions, boosting the fish population within them and in areas surrounding them.
