This study was conducted to find out accumulated concentration of nickel, survival rate and falling rate, structural changes of abalone, Haliotis discus hannai exposed to nickel chloride. Experimental groups were composed of one control condition and five nickel chloride exposure conditions (5.9, 8.8, 13.3, 20.0, 30.0 mg/L). The accumulation of nickel in abalone was significantly increased all exposure group. Though the exposure groups had lower survival rate than the control group, higher falling rate than the control group. Histopathological changes in the foot, gill and hepatopancreas of abalone revealed obvious with exposure group than control group
