Can Still be Reversed, Study Says

Although the majority of global fisheries remain in decline, they can still rebound if managed sustainably, according to a new study. In a comprehensive statistical analysis of the world’s 10,000 fish

The Unfulfilled Promise of the World’s Marine Protected Areas
Biologists and conservationists maintain that establishing marine reserves offers the best hope for recovery for our overstressed oceans. So why, Bruce Barcott writes, is such a small area of the world's oceans protected?

stocks, nearly 80 percent of which are not regulated, a team of U.S. scientists found that the world’s smaller, managed fisheries are in far worse shape than larger, regulated ones. But while those smaller fisheries, such as those for snapper, are in steep decline, “they’re not yet collapsed,” said Christopher Costello, an economist at the University of California at Santa Barbara and lead author of the study, published in the journal Science. According to the analysis, effective management of unregulated fisheries could boost global fish abundance by 56 percent. “If we turn things around now, we can recover them in a matter of years, not decades, and that has big implications for conservation and food security,” Costello said. According to the study, major gains have been made in large fisheries, such as skipjack and albacore tuna, where strong science-based management policies have been enacted, including the closing of some areas to let stocks recover.
