In order to determine the immunomodulatory effect of the dietary intake of levamisole in the Chinese mitten crab, the crab were fed diets containing 0, 100, 200 and 300 mg levamisole kg1 dry diet for 7 days. The total haemocyte count, differential haemocyte count, phagocytic activity, respiratory burst, phenoloxidase activity and lysozyme activity were examined at 0, 2, 4, 6, and 8 weeks after administration of levamisole.
