摘  要:
在水温(23±1)℃和pH6.9~7.3下,采用半静态法研究敌百虫、二氧化氯和聚维酮碘三种常用药物对平均体质量(6.1±0.23)g的卡拉白鱼Chalcalburnus chalcoides的急性毒性。结果表明:敌百虫对卡拉白鱼的24h、48h、72h、96h半致死质量浓度分别为0.40mg/L、0.34mg/L、0.31mg/L和0.29mg/L,安全质量浓度为0.07mg/L;二氧化氯对卡拉白鱼24h、48h、72h、96h的半致死质量浓度分别为28.18mg/L、27.16mg/L和24.93mg/L、23.00mg/L,安全质量浓度为7.57mg/L;聚维酮碘对卡拉白鱼24h、48h、72h、96h的半致死质量浓度分别为119.91mg/L、83.87mg/L、72.78mg/L和64.61mg/L,安全质量浓度为14.13mg/L。三种药物对卡拉白鱼的毒性由高至低依次为:敌百虫>二氧化氯>聚维酮碘。敌百虫对卡拉白鱼毒性较强,在生产中需谨慎使用;二氧化氯和聚维酮碘的安全质量浓度高于生产中常用的泼洒浓度,可安全使用。

摘  要:
The acute toxicity of trichlorphon,chlorine dioxide and povidone iodine to shemaia Chalcalburnus chalcoides with body weight of(6.1 ±0.23)g was studied at water temperature of(23 ±1)℃ and pH 6.9~7.3 using a semi-static test method.The results showed that the median-lethal concentration(LC_(50))of trichlorphon was 0.40 mg/L in 24 h,0.34 mg/L in 48 h,0.31 mg/L in 72 h and0.29 mg/L in 96 h,with safe concentration of 0.07 mg/L,the LC_(50) of chlorine dioxide was 28.18 mg/L in 24 h,27.16 mg/L in 48 h,24.93 mg/L in 72 h and 23.00 mg/L in 96 h,with safe concentration of 7.57 mg/L,the LC_(50) of povidone iodine was 119.91 mg/L in 24 h,83.87 mg/L in 48 h,72.78 mg/L in 72 h and 64.61 mg/L in 96 h,with safe concentration of 14.13 mg/L.The order of toxicity of the three drugs was arranged in descending order as trichlorphon > chlorine dioxide > povidone iodine.The findings indicate that trichlorphon has higher toxicity with caution utilization in aquaculture,and that chlorine dioxide and povidone iodine has lower toxicity and safe use in aquaculture.
