Abstract
An experiment was conducted from Mysis 3 to Post larva 5 of white shrimp, Fenneropenaeus indicus in plastic troughs (100 liters) by feeding enriched Rotifer diets. Larvae fed with enriched Rotifer in Yeast were considered as control, whereas larvae fed with enriched Rotifer in Cod-liver oil and HUFA were designated as treatment 1 and 2. Artemia nauplii fed larvae were considered as treatment 3. A combination of Artemia and enriched Rotifer in Yeast, Cod liver oil and HUFA were also fed to the larvae and were designated as treatment 4, 5 and 6 respectively. Both the control and treatments were replicated thrice, arranged in a completely randomised design. Larvae fed with enriched Rotifer in Cod liver oil showed higher survival rate when compared to control and other treatments. ANOVA shows significant difference on survival between Control and Treatments. Enrichment of Rotifer in Cod liver oil and Yeast for 12 hours at 30 C is found to be an ideal method to increase survival rate of F. indicus larvae.
