"Scallop fishermen off the East Coast could soon see one of their biggest bumper crops ever. A federal survey in waters off Delaware is predicting a boom in the next couple of years for the nation's most valuable fishery.

Every year, the National Oceanic and Atmospheric Administration looks for young sea scallops on the bottom of the Atlantic Ocean. This year, when they stuck their camera in the water, they got a huge shock, says Dvora Hart, a research analyst with NOAA's Fisheries Service.

'We were seeing concentrations of several hundred per square meter, and to give a perspective on that, one per square meter is actually a high concentration,' says Hart."
