Body composition, growth performance and enzyme activities of Labeo rohita fed different commercial fish feeds

Abstract We have evaluated the effects of different fish feeds on body composition, growth, and enzyme activities Labeo rohita (Rohu). In total, 240 fishes between average weights 24.77±2.15g were studied. The treatments applied in a completely randomized design, with 4 60 each. Treatments consisted four [Oryza (T1), AMG (T2), Aqua (T3), Supreme (T4)]. Body growth performance, evaluated. There was significant variation performance fed type feed; as having Oryza feed showed highest weight gain, specific rate (SGR), best conversion ratio (FCR) compared to other groups that considered be (P ? 0.05). High net gain obtained T4 when T2 T3. FCR value less than T1 but higher T2, T3 which lowest values. recorded T4, led high SGR Similarly, crude protein level digestive enzymes activity significantly (T1) (T4). Water quality parameters all except pH DO treatment from treatments. It concluded Rohu (Labeo rohita) could show promising protease 25% protein.
