Seven experimental diets&nbsp;<em>viz</em>. T1, T2, T3, T4, T5, T6 and T7 were formulated with graded lycopene levels i.e., 0 (control), 10, 20, 30, 40, 50 and 60 mgkg^-1, respectively and fed to fingerlings using completely randomized design (CRD). During experimental period, fish were fed at 5% of their total biomass. After performing one way Analysis of Variance, it was observed that maximum weight gain % (193%) and best FCR (1.95) was observed in fish group fed diet having 40 mgkg^-1&nbsp;of lycopene. Optimum gross energy (68%), ether extract (77%) and crude protein (75%) values were found in fish at the same level and these values showed significant (<em>p</em>&lt;0.05) difference than the control diet. Lowest percentage of oxidation (3.57%) was observed at test diet having 40 mgkg^-1&nbsp;with the highest antioxidant activity recorded in fish fed T-V diet. It was concluded that lycopene supplemented canola meal-based diet optimally improved growth parameters, nutrient utilization and antioxidant status of&nbsp;<em>C. catla&nbsp;</em>fingerling at 40 mgkg^-1.</p> Lycopene, aquaculture, antioxidant status, canola meal, fish meal Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=Fish-20-0022
