© 2023 Talha Zulfiqar et al.The current experiment is designed to evaluate the effect of different aquafeeds (farm-made versus commercial) on growth, body composition, oxidative capacity, and fatty acid profile in the semi-intensive composite culture system. For this, 1,100 fingerlings/acre having initial body weight and length, Labeo rohita (61.34 g, 171 mm), Catla catla (71.45 g, 181 mm), and Cyprinus carpio (30.80 g, 91 mm) were randomly distributed to 16 ponds and randomly fed on eight different diets (n = 2 pond/diet) in a completely randomized research design. Aquafeed were farm-based diets (D1-D2) and commercial aquafeed (D3-D8). The farm-made diets contained various crude protein levels of maize gluten (24.9%) and rice polish (7.3%), whereas commercial diets were procured from commercial feed plants (AMG, Supreme, Aqua, Star Floating, Hi-Pro, and Punjab feed). The growth performance of carps (L. rohita and C. catla) was significantly improved (p<0.05) by feeding D3 as compared to other diets. Similarly, white blood cell concentration was greater (p<0.05) in all species fed by D3 than in those fed on D7, D8, D5, D6, D1, and D2 fed groups, respectively. Alanine transaminase, aspartate transaminase, and alanine phosphatase activities were significantly lower (p<0.05) in the D3-fed L. rohita, C. catla, and C. carpio compared with those fed on the rest of the treatments. The activities of glutathione peroxidase and superoxide dismutase were also higher (p<0.05) for the D3 fed L. rohita, C. catla, and C. carpio than those fed on the rest diets. The groups fed on D3 and D4 had greater (p<0.05) concentrations of myristic (14), palmitic acid (16), and stearic (18) acids than those fed on the rest of the commercial diets. However, meat chemical composition was similar (p>0.05) across the treatments. These results also prove that the increase in the dietary protein level and lipid content can improve the fish's body's crude protein and fat levels. Feeding D3 improved the production performance, oxidative status, and fatty acid profile in composite major carps culture systems. Thus, based on growth, survival, and body composition, it is concluded that D3 and D4 may be recommended for a commercial culture of major carps. Dietary treatments had no significant impact (p>0.05) on water's physical-chemical properties. Calcium content and alkalinity varied (p<0.05), with D5 showing the lowest calcium and the highest alkalinity.
