A feeding trial was carried out to investigate the dietary vitamin E requirement of the oriental river prawn Macrobrachium nipponense （weight of 0.3-0.4 g） and its effect role on antioxidant activity. Prawns were fed with seven levels of vitamin E （0, 25, 50, 75, 100, 200, and 400 mg/kg diet） for 60 days. The results show that dietary vitamin E supplementation could significantly increased the prawn weight （P〈0.05）. The activity of superoxide dismutase （SOD） in the hepatopancreas was significantly higher in prawns fed with diets supplemented with ≤75 mg/kg vitamin E than in those fed with diets supplemented with 100-400 mg/kg vitamin E （P〈0.05）. The activity of catalase （CAT） in the hepatopancreas decreased significantly as dietary vitamin E supplementation increased （P〈0.05）, and no significant difference was detected in glutathione peroxidase （GSH-Px） activity between different dietary groups （P〉0.05）. The contents of vitamin E in the hepatopancreas and in the muscle increased with increasing dietary vitamin E. There was a linear correlation between the vitamin E level in diet and that in muscle, and between the vitamin E level in diet and that in the hepatopancreas. All the above results indicated that dietary vitamin E can be stored in the hepatopancreas and muscle and lower both the activities of SOD and CAT in the hepatopancreas, suggesting that it is a potential antioxidant in M. nipponense. Broken line analysis conducted on the weight gains of prawns in each diet group showed that the dietary vitamin E requirement for maximum growth is 94.10 mg/kg.
