近年来,随着大鲵养殖规模的迅速扩大,大鲵各种病害也接踵而来。由于大鲵养殖属高投入、高风险行业,大鲵病害的发生与传播,不仅会给养殖户造成巨大的经济损失,也是制约大鲵养殖业健康发展的重要因素。因此,加强大鲵病害的防治,对提高大鲵养殖成活率意义重大。大鲵发病,除自身免疫力降低引发疾病,水体不良是发病的主要因素,加上投饵不科学、管理不当,往往造成病害的严重暴发,所以大鲵病害防治应以防为主,防治结合。因而使用具有高效、快速、安全的 In recent years, with the rapid expansion of aquaculture size, various diseases have also followed. Due to the high inputs and the high-risk pollution in the aquaculture industry, the occurrence and spread of the diseases in the aquaculture industry will not only cause huge economic losses to farmers, but also be an important factor restricting the healthy development of aquaculture. Therefore, to strengthen the prevention and control of the disease of Rana macrophylla is of great significance to improve the survival rate of Rameo mackerel. In addition to the reduced incidence of self-immunity caused disease, poor water body is the main factor in the pathogenesis, coupled with unscientific feeding, improper management, often resulting in serious outbreaks of disease, so the disease prevention and treatment of large rachis should be based on prevention and control combined. Therefore, the use of efficient, fast and safe
