Abstract
Bay scallops, Acquipcctcn irradians, collected from various bays along the Eastern Shore of Virginia and from Bogue Sottnd, North Carolina, were conditoned and spawned in the laboratory, out of their normal spawning period. A thermal stimulus of 21-2100 was used to stimulate spawning, and larvae set in 10-19 days using cultured algae as food. Juvenile scallops were held in plastic trays in the laboratory for one week, then moved to outdoor tanks with flowing, unfiltered seawater. They remained there until they were about 2 mm in width, then moved to plastic screened wooden floats in the field where they reached an average minimum market size (50 mm) in 12·13 months. Mortality of larvae, early post-set scallops and adults is described. The bay scallop appears to be amenable to mariculture. The biological feasibility of rearing bay scallops from egg to market size has been established.
