Causation and Correlation
Well, at least it's not global warming.
A recently published article in the March 30 issue of the journal Science reported that, Overfishing of big sharks along the Atlantic Coast has led to the reduction of bay scallops and other shellfish in the market. The article also reported that it has also led two linked marine species in the food web to the same fate.
The study was carried out by a team of Canadian and American ecologists, led by world-renowned fisheries biologist Ransom Myers at Dalhousie University, has found that overfishing the largest predatory sharks, such as the bull, great white, dusky, and hammerhead sharks, along the Atlantic Coast of the United States has led to an explosion of their ray, skate, and small shark prey species.
â€ūWith 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,â€? says co-author Julia Baum of Dalhousie.
Huh?
