Abstract

To study the effects, of Tetraselmis sp. and Nannochloropsis sp. microalgae on carotenoid concentration, nutrition and biochemical composition of fry Nile tilapia (primary weight 0.023) an 8-week feeding trial was conducted. Treatments were designed with five experimental diets: CF (0% microalgae which is control feed), N25 (25% Nannochloropsis sp.), T25 (25% Tetraselmis sp.), N50 (50% Nannochloropsis sp.) and T50 (50% Tetraselmis sp.) respectively. Two hundred seventy Nile tilapia fry were randomly assigned in 15 rectangular tanks in triplicate. Fish were sampled at the end of 8-week feeding trial to determine the total carotenoid concentration, nutrition and biochemical composition of Nile tilapia body tissue and significant (p< 0.05) changes of values were observed. The Highest protein concentration in whole fish muscle was recorded in control. The Highest lipid and carbohydrate were recorded in N50 and T50 treatment respectively. Comparatively, higher carotenoid concentration was revealed in N50 than control. Increasing dietary Nannochloropsis sp. and Tetraselmis sp. has also significantly (p< 0.05) increased the percentage of saturated fatty acids (SAFs), polyunsaturated fatty acids (PUFAs) like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) compared to control. Thus, this study revealed that microalgae can be a potential source for fish pigmentation, nutrition and biochemical composition.
