Mini RAS for Bangladesh Catfish Farm - Case Study
AquaLifeNet partnered with JAK International to bring the latest biological filtration technology to a Catfish farm in Mymensingh, Bangladesh.
The team installed a Biofishency Mini Re-circulation Aquaculture System (Mini RAS) to treat and re-circulate the water. Biofishency’s project partner, Upgrade Solutions, provided eight corrugated metal fish tanks with PVC liners suitable for high density fish farming. 0.5 g Catfish fingerlings were put into the tanks and after just 7 weeks they had reached a weight of 18 g.
This system is expected to increase the farm’s production capacity way beyond that of a conventional fish pond aquaculture system, with a smaller land requirement. Inside a space of just 3,200 square feet they now expect to produce 10+ tonnes of Catfish per year. It is already producing healthy and uniform size fish in high volume and with less mortality. By reducing the water requirement and adopting a low feed conversion ratio, the farm is also able to reduce its ongoing costs.
This RAS project was designed specifically for Shing and Deshi Magur Catfish, with Pabda and Gulsha Tengra strains also being tested in this project. This Biofishency filtration technology can be modified for all types of fin fish and shrimp. It is already in use in India and the Middle East, where it is even suitable for use in arid and desert conditions with indoor fish ponds.
Additional fish farms can be set up using the AquaLifeNet Community Fish Farming Network model.
