Oysters OPTIMUM AND MINIMUM SALINITY TOLERANCE THROUGH THE SETTING STAGE: A resume of the observations on the salinity tolerance of the eggs, larvae, and set of East Coast and Gulf oysters (Crassostrea virginica) has been prepared (Bulletin No. 3, August 22, 1957) by the biologists of the U. S. Bureau of Commer-. OYSTER LARVAE, HIGHLY MAGNIFIED. cial Fisheries' Marine Biological Laboratory at Milford, Conn. Much of the infor- mation included in the resume can be applied by biologists and members of the in- dustry, who are contemplating, or are now actually engaged in, the use of small salt- water ponds for the culture of commercial oysters. Most of the data were obtained by using, as parents, oysters from Long Island Sound that had developed gonads at a salinity of approximately parts per thou- sand (). Additional experiments are planned using, as parents, oysters kept at lower salinities for several weeks before spawning, and also oysters from different areas. It may be found after additional studies that the recommendations based on the present experiments will have to be revised for oysters from other areas and for oysters that develop gonads at salinities lower than those prevailing in Long Is- land Sound. Eggs: The optimvim salinity for development of the fertilized eggs of oysters that had developed gonads at , was The percentage of eggs.
