| Summary: | Tetraselmis species are widely used as food for aquatic animals such crustaceans, bivalves and fish especially in their larvae stage. Three Tetraselmis strains were successfully isolated from the shrimp farming at Vandon, Quangninh. Among them, Tetraselmis strain T1 showed best growth. Medium f/2 was selected as best medium for its growth. Fatty acid profile of Tetraselmis strain T1 consisted of C16 and C18 acids as most abundant, which is typical for most green algae. Essential fatty acids, -linolenic acid and linoleic acid accounted for 34.2% of total fatty acids, half of total unsaturated fatty acids. Eicosapentaenoic acid (EPA) was also in high concentration. The result suggested the high quality of as food for aquatic animals like geo-duck. On the way to apply Tetraselmis strain T1 in feeding geo-duck, outline for its biomass production was structured. |
