Enhance fish farming efficiency with sustainable water systems, reducing resource wastage and ensuring robust fish growth.
The recirculatory aquaculture system (RAS) technology is an innovative method used in fish farming that optimizes water usage by continuously recycling and purifying water within a closed-loop system. In RAS, water from the fish tanks is filtered to remove waste products and then recirculated back into the tanks, reducing the need for large volumes of fresh water. This technology enables higher fish stocking densities, leading to increased productivity and efficiency compared to traditional aquaculture methods. RAS also allows for better control of water quality parameters such as oxygen levels, temperature, and pH, resulting in healthier fish and reduced environmental impact. Overall, RAS represents a sustainable and environmentally friendly approach to fish farming that maximizes resource utilization and minimizes waste.
This technology is TAAT1 validated.
