Abstract: | The diatom Thalassiosira pseudonana in exponential phase or stationary phase and grown under 3 light regimes was fed to 6 groups of juvenile oysters, Crassostrea virginica Gmelin, for a 10-week period. Oysters fed diets from the stationary phase grew more rapidly and had a higher glycogen content than those fed diets from the exponential phase. The stationary phase, cool white-light diet produced the greatest increase in dry weight, shell height and glycogen content of the 6 diets examined. Oysters grew more rapidly when fed diets richer in carbohydrates than proteins. |
