(from Galtsoff 1964) Common Name: American oyster Scientific Name: Crassostrea virginica Other Common Names: Eastern oyster (Turgeon et al. 1988), huitre creuse americaine (French), ostion americano (Spanish) (Fischer 1978). Classification (Turgeon et al. 1988) Phylum: Mollusca Class: Bivalvia Order: Ostreoida Family: Ostreidae Value Commercial: The American oyster has historically sup- ported a valuable fishery throughout the Gulf of Mexico (Stanley and Sellers 1986). In 1993, 15,241 metric tons (mt) of oyster meat valued at $ million were landed in the United States, and the Gulf region led in production with 9,072 mt of meats (O'Bannon 1994). Led by Louisiana, the Gulf region produced about 8,390 mt and nearly 41% of the national total during that year. Individual state harvests for the Gulf during 1992 have been compiled by Newlin (1993). The west coast of Florida ranked second in Gulf production with 1,571 mt harvested during that season. Alabama and Mississippi landings are typically small, but landings during 1992 were much higher than usual totaling 543 and 321 mt respectively. Louisiana led the Gulf states in production during that year with 5,015 mt of meats. In Texas, the harvest was about mt. Harvest methods include hand picking, tonging from boats, and dragging or dredging from boats (Stanley and Sellers 1986). Most of the Gulf landings are from publically- owned oyster beds, but an estimated 30% of the harvest isf rom privately-leased beds (MacKenzie 1989). Oysters from restricted waters are sometimes moved to approved waters for depuration or further growth. Broken oyster shell, rangia shell, or limestone are sometimes used as substrate to enhance oyster settle- ment and growth in Florida and Louisiana (MacKenzie 1996). Commercial fishery regulations vary among the Gulf coast states, but all oysters harvested must mea- sure at least three inches from hinge to mouth (GSMFC 1993, TPWD 1993a).
