Abstract
    Oyster larvae (Crassostrea virginica) of seven different size groups were fed different concentrations of Isochrysis galbana. The optimum concentration of I. galbana for each size group was determined by measuring the increase in mean length of larvae during the 48 hr test period. The optimum concentration increased with increasing larval size and ranged from 2.5 µl of packed cells per liter of larval culture for larvae 74 µ long to 32.5 µl of packed cells per liter of larval culture for larvae averaging 246 µ in length. It was found to be more efficient to increase the Isochrysis concentration as the larvae grew than to feed the larvae at constant rates.
