Effect of Enzyme Supplementation in Diet on Growth of Common Carp (Cyprinus carpio L.) juveniles in RAS

Abstract

Abstract The purpose of this study was to determine the effect of supplementing the diet with Thepax Aqua (Aqualase) on the development and survival of juvenile common carp (Cyprinus carpio L.). Therefore, an eight-week nutrition experiment was carried out using the Thepax Aqura enzyme in the Department of Vertebrates, Marine Science Center, University of Basrah. This enzyme was supplemented at 1, 2, and 3% in the control diet. The maximum weight growth (3.9870 gm 0.1230) and Specific Growth Rate (0.4238 gm 0.0049) were seen in the fish fed with T1 diet, and these results were found to be statistically different (P<0.05) from those observed in the fish fed with T2 (2 %), T3 (3 %), and T0 (control) diets. This study also concluded that there was no significant effect (P≤0.05) for enzyme levels on the survival of juveniles carp fed with different dietary enzymes. Finally, the outcome of the current experiment showed that the 1% supplementation of Thepax Aqua to the food gave good growth and feed utilization of Juveniles of carp C.carpio.
