夏秋之际,高温炎热,有时气温高达37～38℃,一般按照常规的方法防治鱼病,其效果不明显,甚至引起大批鱼死亡。现将高温防治鱼病注意事项介绍如下:1、鱼塘平均水深不到80厘米,水温在30℃以上,防治鱼病不可全池泼洒,否则容易引起死鱼。因为在化学反应中,温度每上升1℃,药物反应速度加快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,因酸碱中和,疗效减弱。敌百虫与碱发生反应变成敌敌畏,毒性会增加10 Summer and autumn, hot and hot, and sometimes temperatures as high as 37 ~ 38 ℃, generally 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. The high temperature prevention and treatment of fish disease precautions are described below: 1, the average depth of fish ponds less than 80 cm, the water temperature above 30 ℃, prevention and treatment of fish disease can not be completely pond spilled, otherwise easily lead to dead fish. Because in the chemical reaction, the temperature increased by 1 ℃, the drug reaction speed up 1 times. Each increase of 10 ℃, the toxicity will increase 2 to 3 times. 2, bleaching powder, copper sulfate, trichlorfon and lime can not be applied at the same time, due to acid and alkali, curative effect weakened. Trichlorfon reacts with alkaloids to become dichlorvos and increases toxicity by 10%
