夏季有时气温高达37—38C,按照常规方法防治鱼病,其效果不明显,甚至引起大批鱼死亡。高温防治鱼病应注意:1、鱼塘平均水深不到80厘米,水温在30℃以上。鱼药不可全池泼洒,否则会引起死鱼。因为温度每上升1℃,药物反应速效加快1倍;每上升10℃,其毒性会增加2—3倍。2、漂白粉、硫酸铜、敌百虫均不能与生石灰同时施用,以免疗效减弱。敌百虫与碱发生反应会变成敌敌畏,毒性增加10倍。3、鱼塘水
Sometimes summer temperatures as high as 37-38C, in accordance with the conventional method of prevention and treatment of fish disease, the effect is not obvious, and even caused a large number of fish died. Fish disease prevention and treatment should pay attention to: 1, the average depth of fish ponds less than 80 cm, the water temperature above 30 ℃. Fish drugs can not be spilled, otherwise it will cause dead fish. As the temperature rises 1 ℃, the drug response speed up 1 times; each increase of 10 ℃, the toxicity will increase 2-3 times. 2, bleaching powder, copper sulfate, trichlorfon and lime can not be applied at the same time, so as to avoid curative effect. Trichlorfon and alkali reaction will become dichlorvos, increased toxicity 10 times. 3, fish pond water
