近年来,随着水产养殖业的迅速发展,水域污染问题也日趋突出,加上大量的富含氮、磷的工业废水、生活污水及农业废水排入江、河、湖,致使水体中的藻类和其他浮游生物迅速繁殖,水体溶解氧下降,造成水域生态环境恶化。养殖生态环境的恶化,引起暴发性水产病害的发生,给水产养殖业造成不同程度的经济损失,已经成为制约水产养殖业健康持续发展的关键因素之一。
In recent years, with the rapid development of aquaculture, the problem of water pollution has become increasingly prominent. With a large amount of industrial wastewater containing nitrogen and phosphorus, domestic sewage and agricultural wastewater are discharged into rivers, rivers and lakes, resulting in the formation of algae and Other plankton multiply rapidly and the dissolved oxygen in water decreases, causing the ecological environment in the water to deteriorate. Aquaculture industry has become one of the key factors restricting the healthy and sustainable development of aquaculture due to the deterioration of aquaculture ecological environment and the occurrence of outbreaks of aquatic diseases, which will cause varying degrees of economic losses to aquaculture.
