Abstract
An experiment was conducted to determine the growth and biochemical performance of ornamental fish Carassius auratus, for 40 days. In the present study to examine the effects of the three different types of feed namely, Sargassum ilicifolum, Padina tetrastromatica and Gracilaria corticata, at different concentrations in growth and biochemical parameters such as protein, lipid and carbohydrate were studied in C. auratus. The fish fed with S. ilicifolium 20%, 30% 40%, P. tetrastromatica 20%, 30%, 40% and G. corticata 20% 30%, 40% and control (0% seaweed ) different experimental diets, in place of fish meal as protein source at 5% of the body weight. The results also clearly showed that C. auratus fed with diet 40% Gracilaria corticata meal dietary inclusion perform the best result among experimental diets. Although fishmeal is non replaceable but can be supplemented with seaweed meal up to an optimum level to produce cost effective fed for C. auratus.. There was significant difference (P<0.05) in growth and biochemical parameters of fish that were fed with experimental diets.
