%X The toxic effects of water soluble fraction (WSF) of crude oil on scallop Chlamys farreri were examined through exposure tests at different concentrations. The activities of antioxidases in gill and digestive glands were examined. The results showed that the activities of both SOD (Superoxide Dismutase) and CAT (Catalase) in gills and digestive glands showed a decrease-increase-decrease trend with increased exposure time. Time for the enzymes to reach their highest activities varied with the concentration of WSF. The activity of SOD in digestive gland was induced by 0.08 mg/L of WSF on the 1st day of exposure, followed by inhibitory effect. The digestive gland enzyme activities were inhibited first and then increased with time at 0.21 mg/L and 0.88 mg/L of WSF. At the 4th day of the test, the activities of SOD in gills gland were inhibited by both 0.08 and 0.88mg/L of WSF but induced by 0.21 mg/L of WSF. Our study indicated that the SOD activity could be used as a stress indicator of Chlamys farreri when exposed to petroleum polluted environments.
