Present study was conducted to study the effect of varying level of dietary lipid on the growth, Feed conversion ratio (FCR) and body composition of the juveniles of Labeo rohita. Group of 25 juveniles in triplicate (average weight 0.022 gm ± 0.002 gm) were fed on three iso-nitrogenous experimental diets containing (40% protein) and varying levels of lipid i.e., 6%, 9% and 12% for a period of 60 days. Results revealed that the best increment in growth was obtained with 9% supplementary lipid (%WG 26.08 ± 0.681) followed by the diet containing 12% lipid (%WG 23.41 ± 1.646) and least with 6% lipid (%WG 22.71 ± 1.540). FCR and FCE shows inverse relation as highest value of FCE (9.35) and least value of FCR (10.70) was obtained in juveniles fed on 9% lipid diet with significant differences (p ≤ 0.001). Further biochemical analysis revealed that highest value of muscle lipid has been found in juveniles fed on 9% lipid diet i.e., 1.11 gm and least with diet containing 6% lipid i.e., 0.78 gm. Thus, based on the present results, it could be concluded that an artificial feed with 9% supplemented fish oil is sufficient without any adverse effects on growth performance and muscle quality.
