Abstract: Activities of superoxide dismutase(SOD)and catalase(CAT)，and total antioxidant capacity(T－AOC)were determined in juvenile rock scallop Crassadoma gigantea with shell length of(36.39±4.45)mm exposed to water temperature of 5，10，15，20，and 25℃，warming－up at 1℃ a day from low temperature，to investigate the influence of temperature changes on antioxidant enzymes activity of juvenile rock scallop.There was significantly lower SOD activity at 5℃ than that at other temperatures(P＜0.05)，without significant difference from 10℃ to 25℃(P＞0.05).The rock scallop had significantly higher CAT activity at 25℃ than the animals did at other temperatures(P＜0.05)，without significant difference from 5℃ to 25℃(P＞0.05).The T－AOC was shown to be significantly higher at 15℃ than at the other temperatures(P＜0.05)and to be significantly lower beyond 15℃，especially over 15℃(P＜0.05).The findings reveal that CAT activity in gills is induced and capacity of T－AOC in gills is inhibited at high temperature and that low temperature led to a significant inhibitory effect on activities of TAOC and SOD in the tissue fluid of rock scallop，indicating that 15℃is of optimal temperature for growth of rock scallop.
