Overfishing May Harm Seafood Population By RANDOLPH E. SCHMID WASHINGTON (AP) - Clambakes, crabcakes, swordfish steaks and even humble fish sticks could be little more than a fond memory in a few decades. If current trends of overfishing and pollution continue, the populations of just about all seafood face collapse by 2048, a team of ecologists and economists warns in a report in Friday's issue of the journal Science.
"Whether we looked at tide pools or studies over the entire world's ocean, we saw the same picture emerging. In losing species we lose the productivity and stability of entire ecosystems," said the lead author Boris Worm of Dalhousie University in Halifax, Nova Scotia. "I was shocked and disturbed by how consistent these trends are - beyond anything we suspected," Worm said.
While the study focused on the oceans, concerns have been expressed by ecologists about threats to fish in the Great Lakes and other lakes, rivers and freshwaters, too.
Worm and an international team spent four years analyzing 32 controlled experiments, other studies from 48 marine protected areas and global catch data from the U.N. Food and Agriculture Organization's database of all fish and invertebrates worldwide from 1950 to 2003.
