Abstract: An experiment was conducted to assess the effect of chitosan supplemented diets on survival and growth parameters of Indian bagrid catfish, Mystus seenghala. Five different concentrations (2.0, 4.0, 6.0, 8.0 and 10.0) and control without chitosan incorporated with total fish feed for 60 days. Insignificant variations in physical and chemical parameters of experimental water except pH were found. Studies revealed an ascent in final weight contrasted to initial weight in all treatments. An increasing pattern from D2 to D4 following a decline in D5 and D6 chitosan supplemented diets was calculated in percentage of weight gain, daily weight gain, specific growth rate, feed efficiency ratio and survival rate however food conversion ratio slashed with the increase of chitosan in experimental diets. The distinction of these parameters contrasted with control was found significant (p<0.05). Although the protein content of chitosan was more than the control feed. The investigation inferred that the chitosan incorporated into diets of bagrid catfish increased survival rate and improved the growth performance of fish. The work is one of the benchmark data for directing more exploration on the locally accessible feed fixing like chitosan especially with Mystus seenghala.
