Tianzheng Group has set up modern fishery bases in Dalian and Tangshan, respectively with large circulating aquaculture and breeding workshops. The circulating aquaculture system cited by Tianzheng Group is characterized by modernization, high density, high yield, energy conservation and environmental protection. It is a scientific and technological aquaculture environmental protection project jointly developed by Tianzheng Group and Yellow Sea Fisheries Research Institute.
The recirculating aquaculture system is designed to use a fully enclosed bacteria control workshop, which is particularly advanced in water flow pattern control, light and heat control, wall insulation, bacteria control, etc. It can achieve efficient and high-yield environmental aquaculture. Each cubic meter of water can breed more than 35 kilograms of rare marine fish, which is more than 300% higher than the traditional factory aquaculture efficiency, and achieve a true sense of high density. At the same time, the clean technology based on biological filtration has also greatly reduced the sewage discharge.
Lei Jilin, a researcher of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences and an academician of the CAE Member, spoke highly of the recycling aquaculture of Tianzheng puffer fish: Tianzheng's aquaculture model is fully developed in accordance with the concept of "industrial aquaculture", and will certainly become a model for the national aquaculture industry to promote "industrial aquaculture" and build a modern fishery.
