鱼种消毒就是在鱼种放养前根据鱼的体质瘦弱、水温等情况,用各种药物配制成不同浓度的药液,通过采取浸洗鱼体、全池泼洒等措施,杀灭鱼体上附着的寄生虫、细菌等病原体,达到预防鱼病发生提高鱼种成活率的目的。鱼种消毒不但能提高放养鱼种的成活率而且是成鱼养殖成功与否的关键。否则,将会把病原体带入鱼池引起鱼病,严重时可导致鱼种大批死亡,乃至全池覆灭,所以鱼种放养的消毒工作尤为重要。 一、鱼种消毒大致可分为两种方法:浸洗法和泼洒法。 1.浸洗法,即放养前将鱼种浸在一定浓度的药液中,通过适当时间的药液浸洗,鱼体上的病原体被杀死,达到消毒目的。浸洗时间的长短,根据鱼的大
Fish species disinfection is in accordance with the species of fish before the fish stocking thin, water temperature and other conditions, with a variety of drugs formulated into different concentrations of liquid, by taking immersion fish, Quanchiposa and other measures to kill fish attached Of parasites, bacteria and other pathogens, to prevent the occurrence of fish diseases to improve the survival rate of species purposes. Fish species disinfection will not only increase the survival rate of stocking fish species but also the key to the success of adult fish farming. Otherwise, the pathogens will be brought into fish ponds to cause fish diseases. In severe cases, fish species may die in large numbers, and even the whole pond will be destroyed. Therefore, the disinfection work of species stocking is especially important. First, species disinfection can be broadly divided into two methods: dip method and sprinkle method. 1. Dipping method, that is, before stocking the fish immersed in a certain concentration of liquid medicine, through the appropriate time immersion liquid, the fish pathogens are killed, to disinfection purposes. Dipping time, according to the fish
