Keyword:  兴凯湖翘嘴鲌敏感性试验安全浓度;
Abstract: 在p H7.1~7.9、溶解氧5mg/L以上、水温20~24℃的静水条件下,采用急性毒性试验方法进行车轮净、复合H高聚碘、特效杀虫灵、二氧化氯等四种特定水产药物对兴凯湖翘嘴鲌幼鱼的急性毒性试验。试验结果显示,各药物的TLm24、TLm48、SC分别为:车轮净0.0096mg/L、0.0057mg/L、0.0006mg/L;复合H高聚碘46.66mg/L、39.99mg/L、8.818mg/L;特效杀虫灵0.566mg/L、0.528mg/L、0.138mg/L;二氧化氯4.843mg/L、4.196mg/L、0.945mg/L。依据以上各水产药物对兴凯湖翘嘴鲌幼鱼48h TLm的大小排列可知,其毒性大小依次为:车轮净>特效杀虫灵>二氧化氯>复合H高聚碘;各药物对兴凯湖翘嘴鲌幼鱼SC大小依次为:车轮净<特效杀虫灵<二氧化氯<复合H高聚碘,并对以上各水产药物使用的相关问题进行了分析讨论。
