    Since the oyster life cycle became known in the late s, researchers have studied the artificial rearing of oyster larvae. Hatchery development in the U.S. began along the east coast, where consumer demand for the eastern oyster (Crassostrea virginica) and cyclical oyster fishery production stoked interest in commercial oyster Size: KB. Crassostrea virginica (Gmelin), the eastern oyster, is a broadcast spawner with external fertilization and a plank-tonic larval duration of 2 to 3 weeks before settlement (Galtsoff, ).

In both the Mangrove oyster, Crassostrea rhizophorae, and the Pacific oyster, Crassostrea gigas - and the same is true for the American oyster, Crassostrea virginica - growth, development and survival are near optimal at 28ºC and at a salinity of 25 PSU. Larvae will also tolerate salinities as low as 10 PSU but survival suffers at 5 PSU.

The Eastern Oyster is the most comprehensive synthesis about the biology of Crassotrea virginica since Paul Galtsoff published his landmark work, The American Oyster, in The Eastern Oyster extends Galtsoff's findings and adds considerably to details on such topics as anatomy, shell structure, and predators and by:   Excerpt from The American Oyster Crassostrea Virginica Gmelin The influence of other factors of the environ ment on the shape and sculpture of oyster shell has been reported by many investigators who noticed that specimens growing in calm water on flat surfaces have a tendency to acquire a round shape and to have poorly developed by: The book on American oysters, CrasllQstrea trirginw, of the Atlantic and Gulf States has been writtenfor biologists, administrators of oysterresources of various States, public health officers, students of marine biology, and oyster growers who may heinterested to learn about thelife history and mode of living of this species.

The American Oyster (Crassostrea virginica) is widely distributed in Chesapeake Bay where it grows in the intertidal zone to depths of about m.

The salinity range over which it occurs, is from about 5 to 34 ° /oo. It is most abundant in protected embayments where bottoms are a firm sand-clay mixed The larval American oyster shelly material. This bivalve is a filter feeder, and ingests planktonic material which.

In Congress passed the National Sea Grant College Program Act to promote marine research, education, and extension services in institutions along the nation's ocean and Great Lakes coasts. The larval American oyster In Maryland a Sea Grant Program -- a partnership among federal and state governments, universities, and industries -- began inand in the University of Maryland was named the nation's 4/5(2).

Most oyster culture on the North American Atlantic coast uses the American cupped oyster. There is some culture of the European oyster Ostrea edulis.

In western North American in the late s, pollution and overfishing depleted the beds of the native Olympia oyster Ostrea conchaphila, so Crassostrea virginica was imported from the east coast.

Life cycle of the eastern oyster, Crassostrea virginica. duction of the native American oyster, Crassostrea virginica, and the opening of commercial hatcheries have led to an interest in its genetic study. The basic breeding system of the oyster has been studied (LONGWELL and STILES ).

Cytogenetic investigations of its chromosome complement (LONGWELL et al.
