In recent years, with the continuous increase of stocking density, aquaculture overuse, feeding, fertilization caused its own pollution and industrial pollution caused serious disease, so that production suffered losses. In order to further develop aquaculture urgently, I reviewed the Leetow Freshwater Fish Research Center in the eastern United States, the Fish Diseases Institute at the Stirling Institute in the United Kingdom, and participated in the academic exchange activities held in Western European countries such as France, Italy and Austria, Some countries and regions related to the management and application of aquatic drugs.
