Further, these surveys provide information on the sediment and marine benthic habitat associated with the sea scallop fishing grounds. Sea scallop densities have increased in the three closed areas of Georges Bank. These video surveys were expanded to include the sea scallop density and size distributions along the off-shore northeast waters of the United States in 2003. Sea scallop densities in the Mid-Atlantic (26,270 km2) and Georges Bank (28,523 km2) ranged from 0.04 to 0.79 and 0.09 to 0.26 scallop•m-2, respectively, and represented approximately 217,520 mt tons of scallop meats (approximately US$2.4 billion). On Georges Bank 82% of the sea scallop biomass was located within the three closed areas, while 36% of the scallop resource in the mid-Atlantic was within the closed areas. In the Georges Bank closed areas the proportion of sea scallop pre-recruits (
