近年来,广西淡水养殖鱼因病害大量死亡,造成严重的经济损失。因此,对淡水养殖鱼类常见疾病的诊断和治疗方法进行研究就显得十分必要。冬季淡水鱼类大部分处于休眠状态,经过长期饲养,水池中含有大量的鱼类粪便、残饵等污染物,造成了池塘环境污染严重的现象,导致鱼类容易受到各种病害的影响,如果不能够及时处理容易出现大面积的死亡,给鱼类养殖户带来比较大的经济损失。因此应当加强对淡水鱼冬季常见病的研究,做好相关的防治措施,提高鱼类养殖的经济效益。
In recent years, a large number of freshwater fish in Guangxi died due to disease, causing serious economic losses. Therefore, it is necessary to study the methods of diagnosis and treatment of common diseases in freshwater aquaculture. Most freshwater fish in winter are dormant. After long-term feeding, the pond contains a large amount of pollutants such as excrement and remnants of fish, causing serious environmental pollution in the pond. As a result, fish are easily affected by various diseases. If They can not handle large-scale deaths in a timely manner and cause great economic losses to fish farmers. Therefore, it is necessary to strengthen research on common diseases of freshwater fish in winter and make relevant prevention and control measures to improve the economic benefits of fish farming.
