This study was conducted to find out concentration of trace metal, survival rate, falling rate and structural changes of the abalone Haliotis discus hannai exposed to nickel chloride. Experimental groups were composed of one control condition and four nickel chloride exposure conditions (7.0, 12.0, 17.0 and 22.0 NiCl2 mg/L). The concentration of nickel in abalone was significantly increased all exposure groups. Though the exposure groups had lower survival rate than the control group, falling rate higher than the control group. Histopathological changes in the foot, gill and hepatopancreas of abalone was revealed prominently with exposure group than control group.
