This study was performed in order to investigate the effects of taurine on cadmium poisoning in muscle, gill, and bone tissues of wild goldfish. For this experiment, 80 wild goldfish were divided into four experimental groups: 0.3 mg/L of cadmium and 0 mg/L of taurine (Group Ⅰ), 0.3 mg/L of cadmium and 20 mg/kg of taurine (Group Ⅱ), 0.3 mg/L of cadmium and 40 mg/L of taurine (Group Ⅲ), and 0.3 mg/L of cadmium and 80 mg/L of taurine (Group Ⅳ). The results were as follows: The cadmium concentration in muscle tissue of wild goldfish was 0.65-3.21 mg/kg wet wt in GroupⅠ, whereas it decreased in Group Ⅳ. Levels of cadmium in gill tissue of wild goldfish were 16.57-42.39 mg/kg wet wt in Group Ⅰ, 15.23-43.01 mg/kg wet wt in Group Ⅱ, 15.11-39.56 mg/kg wet wt in Group Ⅲ, and 13.15-38.55 mg/kg wet wt in Group Ⅳ (P 0.05), suggesting that the cadmium concentration decreased in the experimental groups compared to control. The cadmium concentration in bone tissue of wild goldfish after 28 days was 0.52-9.75 mg/kg in Group Ⅱ, whereas it increased in Group Ⅲ (P 0.05). In conclusion, taurine may have a preventive effect against cadmium accumulation in biological tissues.
