Two experimental diets, containing 35% crude protein (P35) and 1628.4 kJ digestible energy and 45% crude protein (P45) and 2088.8 kJ digestible energy with protein to energy (P/E) ratio of 21.5 mg protein kJ-1 in both diets, were fed at incremental rates (1.0, 1.5, 2.0, 2.5, 3.0, 4.0 and 5.0% of body weight day-1 (Bw.d-1) to murrel (Channa striata) fingerlings for 8 weeks. A linear increase in growth rate of fingerlings was observed up to 10.5 g protein (kg Bw.d) -1 and 488.51 kJ energy (kg Bw.d) -1 in P35 diet (r2=0.83) and 11.25 g protein (kg Bw.d) -1 and 522.2 kJ energy (kg Bw.d-1) in P 45 diet (r2=0.89). Regressing growth rate obtained for both the diets to zero weight gain, resulted in a maintenance requirement of 0.3 g protein (kg Bw.d) -1 and 16.6 kJ energy (kg Bw.d-1). The net gain in body protein also increased linearly with increasing feeding rates up to 10.5 g prot.. View More»
