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.

Maximize fish production, minimize expenses, and ensure top-tier product quality through RAS technology. Enhance operational efficiency, mitigate environmental impact, and stimulate economic progress within your locality. Position yourself as a pioneer in sustainable aquaculture methods and innovation.
Regarding expenses, take into account the estimated costs for recirculation pumping and piping, approximately USD 22,000, and mechanical, physical, biological, and chemical treatment, around USD 44,000 for a 130 m3 tank. Additionally, factor in water supply and treatment expenses, influenced by drainage specifics. Contractor fees for constructing a settling pond typically range from USD 1.5 to 5 per square meter, depending on soil type and lining materials.
Given the widespread availability of this technology, consider delivery expenses to the project site and account for any import-related fees.
Collaboration with agricultural development institutions and agro-dealers can facilitate effective implementation.
Furthermore, explore the incorporation of complementary technologies like All Male Tilapia Fingerlings with Greater Yield and Uniformity and Fast Growing and Hybrid African Catfish to maximize overall efficiency.
