RAS system
Recirculating Aquaculture System (RAS) circulating water technology is a technology that can change aquaculture in open water bodies into controlled environment farming. This technology can continuously renew the water body and has unique technical advantages. When using RAS technology to breed aquatic products, it is necessary to start from the hydrological conditions of the breeding site and make different adaptive designs in each link of the system.
First of all, circulating water technology can turn the uncontrollable breeding environment into controllable, basically eliminating the influence of external factors (such as harmful bacteria, viruses, pesticide residues in the soil, excessive heavy metals, etc.) on organisms. In the process of recirculating aquaculture, not only do not need to add any antibiotics, but also add various beneficial bacteria to help the fish intestines restore health, so that the produced aquatic products are truly healthier and pollution-free.
Secondly, the circulating water plant is different from the traditional soil pond culture, it can be built on any land for agricultural facilities or industrial land. Circulating water plants can be built around super cities, such as Chongming Island in Shanghai, Shenshan Cooperation Zone in Shenzhen, and Development Zone in Chengdu. Therefore, circulating water technology can to a certain extent solve the problems of loss, cold chain, and water truck logistics costs caused by the logistics and transportation of production and sales during aquaculture. However, considering the actual cost of water for aquaculture, the factory needs to be located in an area close enough to the water source to optimize the cost structure.
Finally, recirculating aquaculture technology can meet the needs of agricultural orders, and can plan production in advance according to species and quantity. In the production process, it is possible to use AI image recognition (to assist in the inventory of biological assets), automatic feeding machines (to save labor costs), and automatic fish screening/separation devices (to reduce external disturbance of biological growth and reduce mortality), which has the advantages of Many advantages. For fresh food e-commerce companies such as Hema and Dingdong, the quality control of aquatic products has always been their biggest pain point, and the circulating water technology is exactly what makes the production process fully transparent, real-time inventory, and predictive breeding The cycle can help downstream fresh food e-commerce companies to provide consumers with a stable and healthy supply of goods.
