AB  - This study was designed to determine the dietary zinc requirement of <I>Misgurnus anguillicaudatus</I> by decision the effect of the graded levels of dietary zinc on growth, immune response and antioxidative. A total of 540 <I>Misgurnus anguillicaudatus</I> (initial weight 3.3&plusmn;0.1 g) were randomly distributed into 6 groups of each three replicates, feeding diets containing graded levels of zinc (0, 15, 30, 60, 90 and 120 mg kg<SUP>-1</SUP> diet) for 80 days each group were sampled to measure weight gain, Specific Growth Rate (SGR), relative fatness and feed efficiency; protease, lipase and amylase activities in intestine and hepatopancreas the hago-rate erythrocyte, survival rate after vaccination, the Alkaline Phosphatase (AKP) and lysozyme activity in plasma; the Total Antioxidant enzymes (T-AOC), Catalase (CAT), Superoxide Dismutase (SOD), CuZn superoxide dismutase (CuZn-SOD) activities and Malondialdehyde (MDA) in plasma and hepatosomatic. Results indicate that the weight gain rate and SGR of dietary treatments were significantly the highest than group A. The group C was great significantly increased trypsin, lipase and amylase activities in intestine and hepatopancre. Zinc great significantly increased the hago-rate erythrocyte. AKP and lysozyme activity of group C in plasma were the highest than group A. The activities of T-AOC, CAT, SOD and CuZn-SOD of group C in plasma and hepatosomatic were great significantly increased than group A. The MDA of group C in plasma and hepatosomatic was great significantly decreased than group A. In summary, the optimal dietary zinc content for optimum growth performan, digestive ability and immune function in <I>Misgurnus anguillicaudatus</I> was about 30 mg kg<SUP>-1</SUP> of dietary zinc.
