Abstract: Twelve-week feeding experiment has been conducted to investigate the effects of dietary calcium level on growth performance and mineral contents in Labeo bata (Hamilton, 1822). Nine cages were prepared for rearing the fish and three practical diets were formulated containing graded Ca levels ranging from 0.2% to 1.28%. The diets were used to feed the fish in corresponding treatments of T1, T2 and T3, respectively. Initially, the fish were fed 7% of their body weight which further reduced to the rate of 4% monthly. Stocking density among the treatments was 50 fishes m–3. Initial mean weight of the L. bata fish was 5.08±0.06 g. The mean value of final weight was found significantly higher in the fish group of T3 (17.08±0.04 g) than that of T1 (15.58±0.03 g). The weight gain in T3 (12.04±0.05 g) was significantly higher than that of T1 (10.50±0.10 g). The FCR value was much lower in T3 (2.73±0.02) than that of T1 (3.04±0.05). The mean value of SGR was found considerably higher in the fish group of T3 (1.45±0.01) than that of T1 (1.34±0.02) group. Results showed that the best final weight, weight gain, specific growth rate and FCR were obtained in fish group fed diet containing 1.28% Ca and it could be suggested that 1.28% Ca in the practical diet might improve the growth performance of the Labeo bata fish.
