Abstract：To address the issues of poor facilities and direct discharge of tail water during the incubation process of cold-water fish in the north，resulting in low survival rates of fry and environmental pollution. This will promote the transformation of the industry towards standardization and greenness. This study specifically designed a？ "pre-treatment + three tanks and'two dams + artificial wetland enhancement" combined process was designed，and key measures such as pool insulation，covering with straw，and ading low一 temperature bacterial agents were adopted to ensure the operation during winter. The results show that through technical integration and standardized management，a significant improvement in fry survival rate was achieved;the polutants in the tail water were effectively reduced after the system treatment，and they met the discharge or reuse standards.The conclusion indicates that this model has unified the improvement of incubation effciency and the resource utilization of tail water，providing a reference for the sustainable development of the cold一water fish industry in the northern region.
