Fingerlings (initial average weight: 6.35 g) were fed seven graded levels of alpha-tocopherol viz., 0, 100, 200, 300, 400, 500 and 600 mg kg(-1). Triplicate tanks were used and each tank housed 15 fingerlings. Fish were fed at the rate of 5% of live wet weight. Collected data was subjected to one-way analysis of variance (ANOVA). Results showed that fingerlings fed with 200 mg kg(-1) of alpha-tocopherol showed significantly (p<0.05) higher weight gain (32.73 g), weight gain% (261%) and suitable feed conversion ratio (2.49). Among other experimental and control diets, optimum apparent digestibility coefficient (ADC%) of crude protein (CP) (73%), ether extract (EE) (74%) and gross energy (GE) (63%) was noted in the fish fed 200 mg kg(-1) diet. Minimum oxidation (%) (7.66%) was observed at 600 mg kg(-1) predicting that the antioxidant activity increased in a dose-dependent manner.eninfo:eu-repo/semantics/openAccesstocopherolAntioxidant activityAquacultureCorn gluten mealGrowthArticle682869410.21077/ijf.2021.68.2.104861-112-s2.0-85110418927Q4WOS:000703127100011Q4
