| 摘 要： | 2014年10-11月,辽宁某地温室大棚观赏鱼场养殖的孔雀鱼(Poecilia reticulate)普遍暴发了体表变形虫病,其病原初步鉴定为池沼多核变形虫Pelomyxa palustris Greeff。病鱼的主要症状是游动缓慢,食欲减退,以至不摄食;体表两侧局部溃烂,镜检病灶处可见大量虫体。防治试验结果表明:乙酸和过氧化氢混合使用(1∶3),浓度为0.5%~1.0%,浸泡4~5min,有一定杀虫效果。盐酸奎宁浓度为500~1 500mg/L,浸泡15min,有一定杀虫效果。青蒿素+TMP+高甲醚(300mg/L∶60mg/L∶10mg/L)浸泡20~30min,杀虫效果较好。

| Abstract: | From October to November in 2014 ,Guppy cultivated in greenhouse of ornamental fish farm in Liaoyang area commonly broke out amoebiasis .The pathogen was preliminarily identified as Pelo‐myxa palustris .Principal apparent symptoms of diseased fish were swimming slowly ,decreased ap‐petitie ,up to no feeding and fester on partial surface of both sides .A large number of P .p alustris were found in microscopic examination .Experiment results showed that both soaking the diseased fish in 0.5% ~1 .0% mixed liquid of acetic acid and hydrogen peroxide (1:3) for 4~5 min and in 500~1 500 mg/L of Quinine hydrochloride for 15 min had some effect .It had better control effect by soaking the diseased fish in mixed liquid of artemisinin ,TMP and artemether(300 mg/L∶60 mg/L∶10 mg/L)for 20~30 min . |
