Abstract
The configuration of aquatic animals can help to achieve the purification and repair of eutrophic water bodies, and the effect is more significant than that of single aquatic animals. The author elaborated on the development process of aquatic animals’ purification function of water bodies, the environmental purification mechanism of various aquatic animals, and the purification effects of different types of aquatic animal configurations on eutrophic polluted water bodies, and proposed that aquatic animals are urgently needed in the application of eutrophic water purification. Relevant issues that we pay attention to, look forward to the development prospects of the material and energy input and output structure of the aquatic animal allocation system, the restoration of different degrees of pollution, and the annual restoration.
