Since biochemical and physiological indices of goldfish(Carassius auratus) change with mercury concentration to cope with water environmental mercury stress,understanding of the changes in antioxidation system in the juveniles subjected to mercury stress will be important to assess the potential risk of mercury pollution in aquaculture.In this study,the goldfish juveniles were exposed to the different concentrations of Hg2+(0,0.2,1,5 and 10 μg/L) during the exposure period(1 d,7 d and 15 d) when superoxide dismutase(SOD) and catalase(CAT) activities as well as malondialdehyde(MDA) content were sampled and analyzed.The results showed that the activities of SOD and CAT were induced to increase significantly under higher concentration of Hg2+ and with longer exposure time,and the MDA content was also found remarkably increasing in response to mercury exposure.In conclusion,SOD and CAT activities were enhanced to attenuate the damage resulting from the mercury stress,and MDA content was gradually accumulated to be resulted from membrane lipid peroxidation due to mercury stress.
