Microencapsulated diet for larvae and spat of Crassostrea madrasensis

Abstract

Edible oyster larvae and spat were fed with Isochrysis galbane supplemented with microencapsulated diet prepared from oyster, clam or fish oil extracts. In the experiments conducted with oyster larvae, spat setting was higher in the larvae fed with algal diet supplemented with oyster oil extract encapsulated diet than those fed with algal diet. Better growth and more weight increase was observed among the spa1 fed with algal diet supplemented with micro encapsulated diet containing oyster oil and fish oil, compared to that in Oyster spat fed with algal diet alone.
