A feeding trial was conducted to assess the nutritional value of three monospecific microalgal diets for clam larvae, Meretrix meretrix. The three species tested were Chaetoceros TH01, Pavlova TH03 và Thalassiosira TH06. The fatty acids of Chaetoceros TH01, Pavlova TH03 were saturated fatty acids ranged 71.36 to 73.76%; Pavlova TH03 had amounts of HUFAs fatty acids 70,53%, of which MUFAs 31,77%, PUFAs 38,76%. Diatoms contained HUFAs as Eicosatetraenoic acid (ETA), Arachidonic acid (AA), Eicosapentaenoic Acid (EPA). Three species of microalgae included Chaetoceros TH01, Pavlova TH03 and Thalassiosira TH06 all showed good growth in larval size and improved survival rate. Pavlova TH03 was the most suitable for growth stages of clam larvae, with a survival rate of more than 90%, average length of shells met the standard of growth stages of clam which were 120.5 μm (veliger larvae); 420.5 μm (spat larvae). The results iliustrate the importance of experimental testing of algal diets for larvae rather than sole reliance on published nutritional values.
