Aquaculture, as a vital global industry, faces increasingly severe issues of water pollution and restricted fish growth due to traditional farming methods. The recirculating aquaculture system, with its innovative design, employs a synergistic purification mechanism involving physical, chemical, and biological processes to precisely regulate key water quality indicators such as ammonia nitrogen and nitrite, effectively improving the fish's living environment. Practical experience has shown that this system significantly enhances fish growth rates and disease resistance, achieving dual breakthroughs in ecological and economic benefits, providing crucial technological support and new pathways for the sustainable development of aquaculture.
