abstract
A 60 days feeding trial was conducted on magur, Clarias batrachus fingerlings (10.85 ± 0.14 g), fed six isonitrogenous (40% crude protein) diets were: diet T1, fish meal (FM), mustard meal (MM) and cooked rice (CR); diet T2, MM and soybean meal (SM); diet T3, FM, MM and CR; diet T4, equal amounts of FM, MM and groundnut meal (GNM); diet T5, MM, SF and GNM:CR (1:1) and diet T6, MM, SF and GNM:CR (1:2). Fish were stocked in triplicate (100 fish/25 m² earthen tanks) and fed thrice daily (09:00, 13:00 and 18:00 hrs) to apparent satiation. At the end, fish fed diet T6 exhibited the significantly (P<0.05) highest values for weight gain, specific growth rate, average daily gain, protein efficiency ratio and improved food conversion ratio. In conclusion, diet T6 was more effective than other diet combination groups could completely replace FM in the practical diet of magur.
