People have harvested 1)ay scallops for hundreds of years. For example, Bay Scallops have been found in shell middens of Ameri(~an Indians, including the Timucuan Indians whicll inhabited Tampa Bay from 800-1300AD. The bay scallop has been an item of commerce in the United States since L858 (Ingersoll, 1886). They were initially used as fe]~tilizer when there were sufficient quantities to collect. However, commercial harvesting of the bay S(~allop for consumption did not begin until 1870. Until that time they were not popular with consumer~ (Belding, 1910). The introduction of the dreclge in 1874 helped the industry immensely and most harvesting today is still reliant upon the dredge I or other mechanical harvesting technologies, Massachusetts is th{~ leading state in the harvest of bay scallops, producjng between 50 and 80 percent of the national total. In this and producer states there are regulat:ons for licensing, season of harvest, catch limits ancl minimum size allowable for harvest. Yet, even with these restrictions bay scallop landings on the West Coast of Florida have decreased dramatically in the last three decades. Tampa Bay supported a lucrative commercial bay scallop fishery in the early 1960s, now they are seldom found there. It :lS illegal to commercially harvest Bay Scallops in Florida. The large market for bay scallops along with their short time to sexu4u maturity and high fecundity make them an ideal candidate for aquaculture. Many studies have been done on their life cycles and requirements, which alSI) make this a worthwhile endeavor....
