Abstract: Nutrition is the major crucial factor determining the potential of cultured fish to exhibit its genetic capability for growth. In this study, the impact of dietary vitamin E supplementation of fish feed on growth performance, feed conversion ratio and protein efficiency ratio of Gangetic Mystus (Mystus cavasius, Hamilton, 1822) were investigate. Total 150 number of young M. cavasius (weight 33.0±10.0 g) were used the CRD (completely randomized design) method with five treatments and three replications and fed with one of five diets for 45 days. Five different treatments (T0, T1, T2, T3 and T4) with three replication having different level of vitamin E such as 0 mg vitamin E/kg (Control-T0), 50 mg vitamin E/kg (T1), 100 mg vitamin E/kg (T2), 150 mg vitamin E/kg (T3) and 200 mg vitamin E/kg (T4). Feeds supplied at the rate of 5% for first two weeks, 4% for following two weeks and 3% of the body weight for the rest of the experimental period twice daily throughout the study period. At the end of the (15+30) 45 days study period, the highest mean final weight gain 15.65±0.10 in T2, whereas, the minimum final weight gain was 7.725±0.49 in T4. The body length of M. cavasius was not increased significantly (p˃0.05) at different doses of vitamin E supplementation. The food conversion ratio in treatment 0, 1, 2, 3 and 4 were 2.72±0.12, 2.41±0.14, 1.53±0.12, 2.68±0.09, and 3.11±0.10, respectively. Protein efficiency ratio (PER) were found highest (1.96±0.08) at T2 compared to T1 (1.25±0.09), T3 (1.12±0.11) T0 (1.11±0.10), and T4 (0.96±0.10), respectively. The specific growth rate (SGR%/day) in treatment 0, 1, 2, 3 and 4 were 0.79±0.05, 0.91±0.07, 1.37±0.10, 0.87±0.08 and 0.79±0.06, respectively. The best performance found for 100 mg vitamin E/kg containing feed could be the best for growth performance of Gangetic Mystus (Mystus cavasius).
