Effects of different types of lipids enriched supplemental diets containing 1% docosahexaenoic acid (DHA), 1% Phospholipids, 5% Cod liver oil and 1% Cod liver oil and live feed (Tubificid worms) on growth indices and survival of Colisa fasciatus fry were observed.The experiment was conducted in triplicates with a control for 50 days following randomized complete block design (RCBD).The water quality parameters were monitored and found to be within suitable range for freshwater aquaculture.After ending the trial period, significant variations (P<0.05) were observed on the survival and specific growth rate of fry among all the treatments.These results indicate that there are significant variations among different lipids on performance of fry and DHA showed the highest performance regarding growth indices and survival (in close proximity to live feed) among all the biofunctional lipids as an ingredient of supplemental diet.
