The eastern oyster (Crassostrea virginica)—also called Wellfleet oyster, Atlantic oyster, Virginia oyster, or American oyster —is a species of true oyster native to the eastern seaboard and Gulf of Mexico coast of North America. It is also farmed in Puget Sound, Washington, where it is known as the Totten Inlet Virginica.

Crassostrea virginica (Eastern oyster) Taxonomy - Crassostrea virginica (Eastern oyster) (SPECIES).
C. virginica is a benthic, broadcasting bivalve mollusc. C. virginica are abundant in shallow saltwater bays, lagoons and estuaries, in water 8 to 25 feet (2.5 to 7.5 m) deep. Oysters favour estuaries and embayments with low salinities and are intolerant of prolonged exposure to fresh water or marine conditions.

Abstract The 96-h lethal tolerance limits of the hard clam Mercenaria mercenaria (Linne) and the oyster Crassostrea virginica (Gmelin) to ammonia, nitrite ion, nitrate ion, and orthophosphate were defined. Sublethal effects of the chemicals upon the rates at which the shellfish removed algal cells from suspension were also studied.
The high diversity of bindin may have given C. gigas sperm the ability to fertilize eggs of several Crassostrea species, including C. hongkongensis (this study), C. sikamea (Banks et al. 1994), and C. virginica (Allen et al. 1993). Such interpretation is largely speculative, because hybridization and bindin diversity have not been studied extensively in oysters. Further studies are needed to.
Description Crassostrea virginica is elongate and broadly oval reaching up to 18 cm in length. The left valve is convex and sculptured with concentric ridges and lines whilst the right valve tends to be flat. There are a few irregular radiating ribs on the left valve which do not normally meet or indent the margin.
The eastern oyster, Crassostrea virginica, NEWT 6565 is closely related to the Pacific oyster and the partial amino acid sequence of its tropomyosin is identical to that from Crassostrea gigas. The native oyster or edible oyster, Ostrea edulis, NEWT 37623 is used to prepare the oyster extract, Rf290, for the Pharmacia CAP system.
Mapping and classifying Eastern Oyster (Crassostrea virginica) habitat in Copano Bay, Texas, by coupling acoustic technologies. The Texas coast is characterized by an extensive array of shallow turbid embayments containing expansive oyster habitats and is home to a large Eastern Oyster (Crassostrea virginica) fishery.
Crassostrea virginica infected with Tylocephalum metacestodes was examined histologically and histochemically. It appeared that the fibrous capsules enveloping the metacestodes began to develop when the invading parasite compressed the surrounding Leydig cells during migration. Thickening of intercellular fibrous material and infiltration of leukocytes then occurred.
Life cycle of the eastern oyster, Crassostrea virginica. ing veliger stage. At this stage the larva has a thin shell and feeds primarily on tiny algae. After 12 to 20 days, the larva develops a foot and eye spots and is referred to as a pediveliger or “eyed larva.” Pediveligers settle to the bottom and can crawl short dis-tances to find suitable sites for setting. Setting occurs when the.
Species synopsis: The eastern oyster, Crassostrea virginicais a sessile bivalve that is distributed along the eastern coast of the U.S. with a native range extending from Canada to Mexico. They have been introduced for aquaculture purposes to Japan, Great Britain, Australia, Hawaii, and the western coast of the United States (Sellers et al. 1984).
Hemolymph from the oyster, Crassostrea virginica, contains a lysozyme-like enzyme that may function as a defense mechanism against many of the same bacteria that cause human infections. The open circulatory system of the oyster enables an easy extraction of the lysozyme via a sterile syringe.
Among them four species are considered economically important including Crassostrea madrasensis, Crassostrea gryphoides (Schlothein 1813), Crassostrea rivularis (Gould, 1850) and Saccostrea cucullata (Born, 1890). Crassostrea madrasensis, the dominant among them has been selected for this study.Crassostrea virginica Gmelin 1791 (oyster) Bivalvia - Ostreida - Ostreidae. PaleoDB taxon number: 82699. Alternative combinations: Ostrea (Crassostrea) virginica, Ostrea virginiana, Ostrea virginica. Belongs to Crassostrea according to M. Raith et al. 2016. Sister taxa: Crassostrea afra, Crassostrea alabamiensis, Crassostrea angulata, Crassostrea ashleyi, Crassostrea columbiensis, Crassostrea.The native species to the Chesapeake Bay, Crassostrea virginica has declined in population over the past three centuries, prompting this consideration. The states of Maryland and Virginia considered this introduction in hopes to revitalize the oyster industry and improve the water quality in the Bay.
