摘　　要：在常温静水的条件下，用聚维酮碘、灭虫灵、克暴灵、硫酸铜硫酸亚铁合剂、虫菌双杀、杀虫威、益醛、强氯精共8种常用药物对湘华鲮鱼种（全长7．0．10．0cm，体重10．0．20．0g）进行急性毒性试验，结果表明其安全浓度分别为0．76mg·L-1、0．25mg·L-1、0．26mg·L-1、0．37mg·L-1、0．1lmg·L-1、0．05mg·L-1、0．22mg·L-1、0．72mg·L-1；杀虫威、虫菌双杀、灭虫灵、克暴灵、益醛五种药物对湘华鲮的安全浓度较常用浓度低，特别是杀虫威对其作用特别敏感，为其禁用药物，其余四种药物用时应特别小心；聚维酮碘、硫酸铜硫酸亚铁合剂及强氯精对湘华鲮的安全浓度接近常用浓度，是其疾病防治较为理想的药物。In the condition of 24℃-26℃ temperature and static water, the test of acute toxicity of eight commonly used drugs was carried out for juvenile Hunan Chinese dace （S. decorus tungting）. The test drugs were povidone lodine, deltamethrin, phoxim, compound of bluestone and sulfate （5：2）, betacypermethrin, compound of synergstic cypermethrin and abamectin, glutaral, trichloroisocyanuric acid respectively. Their safe concentrations were 0.76mg-L-1, 0.25mg.L-1, 0.26mg.L-1, 0.37mg.L-1, 0.1mg·L-1, 0.05mg·L-1, 0.22mg·L-1, 0.72mg.L-1 respectively for juvenile Hunan Chinese dace. The results showed that the safety concentrations of five kinds of drugs of deltamethrin, phoxim, betacypermethrin, compound of synergstic cypermethrin and abamectin and glutaral were lower than their commonly used concentrations for juvenile Hunan Chinese dace. Compound of synergstic cypermethrin and abamectin was great acute toxicity for tested fish. They should been very cautious to be used for juvenile Hunan Chinese dace. The safety concentrations of three kinds of drugs of povidone lodine, compound of bluestone and sulfate （5：2） and trichloroisocyanuric acid were near their commonly used concentrations. They were considered as disease prevention and control of ideal drugs for Hunan Chinese dace.
