The economic history of the Eastern Shore has been greatly affected by both its natural characteristics and its location. Each has had both good and bad effects, with the very advantages carrying with them serious disadvantages in a bewildering juxtaposition. For instance, the sea and bay provide a boundless resource of commercially desirable species, yet lead to isolation from major markets of the area. The very isolation 0£ the Eastern Shore and its low population density lessens the possibility of pollution, thus preserving the environment on which estuarine animals are dependent. (...)

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 …
