摘要
在室内和池塘试验的结果表明,防治长吻(鱼危)小瓜虫病的方法概括起来有:在水温22.5～27.5℃之间,用0.6～0.8×10^(-6)硝酸亚汞浸洗病鱼20分钟。4小时后再浸洗一次,能杀灭鱼体和鳃上的小瓜虫。浸洗时应注意药物浓度、水温和处理时间等因素;在感染了小瓜虫病的鱼池,遍洒8.0×10^(-6)强力樟桂杀虫剂和50×10^(-6)生石灰,也有一定的效果。
A comparative study on effects of parasiticide, mercurous nitrate, strongly camphor-cassia parasiticide + caustic lime, formaldehyde and malachitegreen to control Ichthyoph-thirius multifiliis on Leiocasis longirostris. The results showed that the parasitized fish had a pharmaceutical bath in 0.6-0.8ppm mercurous nitrate solution for 20 min under 22.5-
27.5℃ of water tempreture.then bathing once again after 4h,the parasites on integument and gill filaments of fish had been killed. In the treatment, the relationship among water tem-preture, pharmaceutical concentration and treated frequency must be coordinated. By spraying the mixed solution of 8.00ppm of the strong camphor-cassia parasiticide and 50.0ppm of caustic lime over fish pond, there was a certain effect yet.
