Abstract：In this study ,growth and alkaline phosphatase (AKP) ,and superoxide dismutase (SOD) activi‐ties were studied in juvenile turbot Scophthalmus maximus exposed to 0 .04 mg/L ,0 .08 mg/L ,0 .16 mg/L ,0 .32 mg/L ,0 .64 mg/L ,1 .28 mg/L ,2 .56 mg/L ,5 .12 mg/L ,and 10 .24 mg/L waterborne Mn(Ⅱ) . The results showed that better growth was observed in the turbot exposed to the waterborne Mn (Ⅱ) con‐centration of less than 2 .56 mg/L ,the best growth at 0 .64 mg/L waterborne Mn(Ⅱ) .The AKP and SOD activities in the liver were shown to be increased with increasing Mn (Ⅱ) concentration ,within less than 0 .64 mg/L .At higher than 0 .64 mg/L in Mn(Ⅱ) concentration ,however ,AKP and SOD activities were decreased dramatically .During various treatment periods ,the maximal AKP and SOD activities were ob‐served in the turbot juveniles exposed to M n (Ⅱ) concentration of 0 .64 mg/L ,indicating that 0 .64 mg/L was inferred as the critical concentration to exhibit toxic effects according to dose‐effect relation .The find‐ings help to assess the toxicity of the water Mn(Ⅱ) to juvenile turbot ,and provide the basis for aquacul‐ture water management for Mn(Ⅱ) including determination of safe concentration .
