| 摘要: |
| 探讨3种水产药物对大泷六线鱼（Hexagrammos otakii）幼鱼的急性毒性影响，确认各药物半致死浓度（LC50）和用药安全浓度（SC）。在水温14.5~16.5℃，盐度22‰~24‰，pH值7.8~8.1，溶解氧 > 6 mg/L条件下，采用静态试验法进行高锰酸钾、聚维酮碘、甲醛等3种药物对大泷六线鱼幼鱼的急性毒性试验。结果显示：高锰酸钾、聚维酮碘、甲醛对大泷六线鱼幼鱼半致死浓度（24 h、48 h、72 h、96 h）分别为（4.10 mg/L、3.89 mg/L、3.46 mg/L、3.17 mg/L）、（19.43 mg/L、18.70 mg/L、17.59 mg/L、16.24 mg/L）和（180.71 mg/L、136.06 mg/L、119.69 mg/L、110.73 mg/L），安全浓度分别为1.05 mg/L、5.20 mg/L和23.14 mg/L。3种药物对大泷六线鱼幼鱼的毒性大小依次为高锰酸钾>聚维酮碘>甲醛。试验结果表明，甲醛、聚维酮碘在实际生产使用量下可放心使用，高锰酸钾需慎用。 |

| Abstract: |
| The effects of three aquatic drugs on the acute toxicity of juvenile fish of Hexagrammos otakii were investigated, and the semi-lethal concentration (LC50) and safe concentration (SC) of each drug were confirmed. Under the condition of water temperature 14.5~16.5℃, salinity 22‰~24‰, pH value 7.8~8.1, dissolved oxygen > 6 mg/L, a static test method was used to test the acute toxicity of three drugs, potassium permanganate,povidone iodine,formaldehyde on juvenile fish of Hexagrammos otakii.The results showed that the semi-lethal concentrations(LC50)of potassium permanganate to Hexagrammos otakii for 24 h,48 h,72 h and 96 h were 4.10 mg/L,3.89 mg/L,3.46 mg/L and 3.17 mg/L,respectively;the 24 h,48 h,72 h and 96 h LC50 of povidone iodine were 19.43 mg/L,18.70 mg/L,17.59 mg/L and 16.24 mg/L;the 24 h,48 h,72 h and 96 h LC50 of formaldehyde were 180.71 mg/L,136.06 mg/L,119.69 mg/L and 110.73 mg/L。The safe concentration was found to be 1.05 mg/L in potassium permanganate,5.20 mg/L in povidone iodine and 23.14 mg/L in formaldehyde. The toxicity of three drugs to juvenile fish of Hexagrammos otakii was potassium permanganate > povidone iodine > formaldehyde. The results showed that formaldehyde and povidone iodine can be safely used in actual production, and potassium permanganate should be used cautiously. |
