漂白粉、硫酸铜、敌百虫等都是预防鱼病的常用药物,它们能不能发挥其药效,和周围环境有很大关系。这些药物在浸洗鱼体时,都不宜在阳光下使用,其疗效和水温、PH值的高低和有机物含量的多少有关系。比如用硫酸铜治疗波豆虫病,夏季用药量一般为0.5ppm,冬季用药量一般为1.4ppm。使用漂白粉,当PH值为8.5时,一次使用4ppm,但是当PH值下降到6.5时,使用1ppm就能达到消毒杀菌目的。使用硫酸铜、敌百虫、敌敌畏等药物时,不要与石灰及碱性物质混合使用,也不要在金属容器
Bleaching powder, copper sulfate, trichlorfon are all commonly used drugs to prevent fish disease, they can play its efficacy, and the surrounding environment has a lot to do with. These drugs in the dipping fish, should not be used in the sun, its efficacy and water temperature, the level of PH value and the amount of organic matter has a relationship. For example, the use of copper sulfate treatment of wave bean worms, the amount of the general dose of 0.5ppm in the summer, winter dosage is generally 1.4ppm. Use bleach, when the PH value of 8.5, 4ppm at a time, but when the PH value dropped to 6.5, the use of 1ppm can achieve the purpose of disinfection and sterilization. Use of copper sulfate, trichlorfon, dichlorvos and other drugs, do not mix with lime and alkaline substances, nor in metal containers
