Growth and maturity of two groups of oysters ('Crassostrea virginica' Gmelin), maintained in cooling water at an estuarine electric power generating station
Growth and mortality of oysters with high and low levels of Labyrinthomyxa marina (L) infection were measured during 1972 in 0.1 ha ponds receiving a continuous flow of heated water from an electric power plant; the power plant intake canal; and the power plant discharge canal. Pond oysters had less cumulative mortality than intake or discharge canal oysters, regardless of Labyrinthomyxa infection. Only pond oysters (high-L and low-L) gained in biomass (increasing 171 and 5,953 g or 2 and 25%, respectively) by the end of the study. In the intake canal low-L oysters decreased 6,293 g(27%) in the 10-month period prior to their disappearance while high-L oysters decreased 6,633 g (64%) by the end of the study. Oysters placed in the discharge canal during warm weather died within six weeks. Oysters held in the ponds grew as well or better than oysters from a natural reef in Galveston Bay. (GRA)
