The addition of Isochrysis galbana H5 ensures a balanced supply of the omega3 and omega6 fatty acids for the survival and healthy of geoduck larvae. This study has shown that the critical factor in this diet for geoduck larvae is the content of polyunsaturated fatty acids (PUFAs), accounted for more than 40 % of total fatty acids, and docosahexaenoic acid (DHA-5.53 mg per mg fresh weight), which play an important role in the membrane lipids. Medium f/2 was selected as best medium for microalgae culture. Isochrysis galbana H5 is recommended as a live food for growing larvae and juvenile of fish, bivalves and crustaceans in aquaculture.
