Abstract:- The study was conducted to assess the impact of different feeding rates and feeding frequencies on the growth and survival of fingerlings of Walking Cat Fish, Clarias batrachus. Test fish were fed with supplementary diet composed of rice bran, mustard meal, meat cum bone meal & soyabean meal (in equal proportions) @10% (FR1), 20% (FR2), 30% (FR3), 40% (FR4), 50% (FR5) & 60% (FR6) body weight. The experiment was conducted for 90 days where 20% feeding rate (FR2) resulted in maximum body weight gain of fish, when reared indoor. Likewise, specific growth rate as well as protein efficiency ratio was also significantly (P<0.05) highest in (FR2). In another experiment, the fishes were fed at three feeding frequencies viz. Once a day (FF1), twice a day (FF2) and thrice a week (FF3) for 60 days. The maximum increase in body weight was observed in (FF1). No significant differences were observed for water quality parameters with respect to different feeding rates and feeding frequencies. It was concluded that feeding rate @ 20% body weight once a day is appropriate for indoor rearing of fingerlings of Clarias batrachus (LINN).
