摘　　要：采用改良的Karber法,求出拜净、硫酸铜、甲醛和食盐对于白斑红点鲑幼鱼,全长(8.7±0.3)cm,24、48、72和96 h的LC50值和安全浓度(SC)。结果表明,4种药物对白斑红点鲑幼鱼的敏感性为:拜净>硫酸铜>甲醛>食盐,安全浓度依次为0.32、0.54、18.86和2 423.65 mg.L-1;24 h的半致死浓度依次为1.39、3.59、146.31和13 412.14 mg.L-1;48 h的半致死浓度依次为1.21、2.67、108.35和10 087.46 mg.L-1;72 h的半致死浓度依次为1.01、2.45、89.52和9 939.32 mg.L-1。试验结果表明,甲醛和食盐对于白斑红点鲑幼鱼是比较理想的日常病害防治药物,且食盐具有净化水质、辅助治疗、刺激食欲等作用。The median lethal concentration（LC50） and safe concentrationresults（SC） of four drugs to Salvelinus leucomaenis for 24,48,72,96 h were computed by the improved Karber＇s method.The result showed that the sensitivity of four drugs to Salvelinus leucomaenis was BayogentCuSO4formaldehyde salt,and the safe concentration of the four drugs were 0.32,0.54,18.86 and 2 423.65 mg·L-1,respectively.The median lethal concertration of the four drugs for 24 h were 1.39,3.59,146.31 and 13 412.14 mg·L-1,which for 48 h were 1.21,2.67,108.35 and 10 087.46 mg·L-1,and for 72 h,were 1.01,2.45,89.52 and 9 939.32 mg·L-1,respectively.The test indicated that formaldehyde and salt were comparative ideal drugs used for diseases prevention and treatment of Salvelinus leucomaenis in daily,and salt was also effective to purificate water quality,assist therapy and excite appetite.
