What is RAS?
Industry Outlook
The recirculating aquaculture system is a new type of aquaculture model that uses water treatment equipment to purify and recycle aquaculture water. Compared with traditional agriculture, it has the advantages of low water consumption, less land occupation, less environmental pollution, safer and healthier products, and is gradually replacing traditional agriculture.
From the perspective of the industrial development environment, various types of pollution caused by traditional aquaculture have seriously damaged the ecological environment
With the improvement of consumption levels, people's demand for green, healthy and nutritious aquatic products is increasing, and traditional earth pond aquaculture can no longer meet the consumption needs of social development.
The incubation stage of RAS
The integrated circulating water hatchery system is a highly integrated fish egg incubation equipment that combines the circulating water technology (RAS) to achieve stable water quality, energy conservation and efficiency improvement, and enhanced hatchery rate. It is suitable for large-scale production of tilapia, catfish, etc.
This is an incubation system that simulates the ecological environment of rivers. It uses mechanical arms to push the water to flow slowly, and combines recirculation water technology (RAS) to achieve stable water quality, energy conservation and efficiency improvement, as well as an increase in hatching rate. This system can incubate trout, sturgeon and cold-water fish, etc.
Tilapia hatching system
Tilapia, as a globally significant economic fish species, its efficient hatching is the key to successful farming. The modern tilapia hatching system, through precise environmental control and automated management, can achieve a hatching rate of over 90% and high uniformity of fry.
nursery stage
The integrated incubation and seedling cultivation system is a highly integrated device for fish egg incubation and early fish seedling cultivation. It seamlessly connects the incubation and seedling cultivation processes, reducing the stress caused by the transfer of seedlings.
The Recirculating Water Culture System (RAS-based Fry Rearing System) is a core technical equipment in modern aquaculture. Through closed water circulation and multi-level water treatment, it provides the most suitable growth environment for aquatic seedlings such as fish fry and shrimp fry. This system can significantly increase the survival rate of seedlings (up to 30-50% higher than traditional methods) and achieve controllable production throughout the year.
Industrialized Recirculating Aquaculture System
The Industrialized Recirculating Aquaculture System (IRAS) represents the highest technological form of aquaculture. Through the use of closed-loop water circulation, intelligent control, and industrialized management, it can achieve a yield of over 100 kg/m³ per unit volume of water (10-20 times that of traditional ponds), making it a core solution for addressing land resource shortages and achieving carbon-neutral aquaculture.
