不同药物对澳洲龙纹斑幼鱼小瓜虫病的治疗效果

小瓜虫病是澳洲龙纹斑鱼人工养殖过程中威胁最大的病害,特别是在幼鱼阶段,致死率高达100%。通过两组药物治疗方案,对比和分析治疗澳洲龙纹斑小瓜虫病的效果。结果表明,试验组药物治疗方案(鱼康乐+氟苯尼考+盐酸土霉素药物制剂+活性腐殖酸钠)防治小瓜虫病鱼的鱼苗成活率高达93.3%,而参照组药物(福尔马林+工业盐)防治小瓜虫病鱼苗存活率仅30.0%。试验药物的优化配方为:鱼康乐2g·t~(-1),氟苯尼考3g·t~(-1),盐酸土霉素药物制剂3g·t~(-1),活性腐殖酸钠0.8g·t~(-1)。

The Treatment Effect Analysis on Different Drugs of Lchthyophthirius Multifiliis in Maccullochella Peelii

Ichthyophthirius disease is one of the biggest disease threat in process of artificial breeding of Maccullochella peelii,especially in the larval stage,mortality rate of up to 100%. In this study,the two drug regimens,comparison and analysis of the treatment of Maccullochella peelii Ichthyophthirius disease effect,to determine the best treatment and determine optimum drug concentration. Experimental results show,In using experimental drugs for treatment scheme (Fish Kangle+Florfenicol+Pharmaceutical preparation of oxytetracycline hydrochloride+Sodiume humate)of Ichthyophthirius disease fish cure rate was 93.3%,in the use of the control drug group (Faure Marin+Industrial salt)in the treatment of Ichthyophthirius disease of fish survival rate only 30.0%.At the same time,to determine the optimum drug concentration for 2 g·t-1 of Fish Kangle,3 g·t-1 of Florfenicol,3 g · t-1 of Pharmaceutical preparation of oxytetracycline hydrochloride and 0.8 g · t-1 of Sodiume humate.
