Abstract:
The present study was conducted to investigate the effect of food restriction and realimentation on compensatory growth and body composition of common carp (Cyprinus carpio var. communis). The fish were subjected to four different feeding regimes: Control or T₀ (fed regularly two times a day, 0S1F), T₁ (one day food restriction followed by one day refeeding, 1S1F), T₂ (two day food restriction followed by one day refeeding, 2S1F) and T₃ (three day food restriction followed by one day refeeding, 3S1F). It was observed that the fish subjected to T₂ (2S1F) and T₃ (3S1F) feeding regimes showed significantly (p˂0.05) lower body weight gain, and specific growth rate (SGR) as compared to the control (T₀) group. However, no significant difference was observed between T₀ (0S1F) and T₁ (1S1F) groups, thus indicating complete compensatory growth in one day food restriction followed by one day refeeding group. The FCR was significantly lower in all the food restriction regimes. With increase in food restriction, the body moisture content increased but crude protein and total lipid content decreased significantly (p˂0.05). No significant difference was observed in the ash content of the fish. The results indicated that one day food restriction followed by one day refeeding could be an efficient strategy for rearing of common carp fingerlings.
