A new study has found that aggressive fishing of large sharks in the Northwest Atlantic may be causing the decimation of the bay scallop fishery along the U.S. Eastern seaboard. Hammerheads, duskies, and other sharks have been over-harvested for their meat and fins, allowing their prey, in particular the cownose ray, to thrive and deplete the scallop population, the research suggests.
