The freshwater pond aquaculture model is a large-scale aquaculture method that centralizes the layout and unified planning and management of multiple ponds. Our company provides standardized transformation and tailwater treatment engineering general contracting for contiguous aquaculture ponds. Through scientific planning and design, we optimize the pond structure, improve the breeding environment, and perfect supporting facilities to achieve standardized, intensive, and ecological aquaculture production, improve aquaculture efficiency, ensure the quality and safety of aquatic products, promote ecological sustainable development, and achieve dual improvement of ecological and economic benefits. The "Three Pools and Two Dams" model is currently the mainstream technical solution for the treatment of freshwater pond aquaculture effluent, which achieves efficient purification and resource utilization of effluent through ecological engineering methods.
