The implementation area of this project is 7282.29 acres, and standardized pond renovation and tailwater treatment will be carried out. The construction of this project further consolidates and enhances ecological environment governance, constructs a spatial pattern, industrial structure, and production mode for green development of the breeding industry, and makes reasonable plans for the breeding and purification areas on the existing basis. It adopts comprehensive management measures of "source emission reduction, process reduction, tail end treatment, and recycling", and adopts an ex situ treatment mode to ensure the recycling or zero discharge of tail water
