Overfishing of sharks makes scallops vanish: study

WASHINGTON, March 29 (Reuters) - Overfishing of big sharks in the Atlantic has cut stocks by 99 percent, dooming North Carolina’s bay scallop fishery and threatening other species including shrimp and crabs, researchers reported on Thursday.
With most of the great predatory sharks — bull, great white, dusky and hammerhead — gone from northwest Atlantic waters, the rays and skates the sharks normally feed on had a population explosion, the scientists said in the journal Science.
“With fewer sharks around, the species they prey upon — like cownose rays — have increased in numbers, and in turn, hordes of cownose rays dining on bay scallops have wiped the scallops out,” said study co-author Julia Baum of Dalhousie University in Halifax, Nova Scotia.

Why is it that whenever ‘man’ gets involved, nature gets screwed up? We always tend to want to ‘help’ Mother Nature out, but we almost always end up doing more harm in the long run. If we didn’t interfere with nature so much, we would have less tendency to feel that we need to help it.
