After RAS, the most modern method of home-based fish farming, various trials of "biofloc" have begun in the country, Shykh Seraj reports. Two young engineers in Uttara, Dhaka, have turned to farming fish with this technology after finishing their studies and are very optimistic about its commercial potential.

Aminul Islam of the Khantek area of Uttara took up farming after retiring from his job. As part of his research into various farming strategies and technologies, he began fish farming with a recirculating aquaculture system (RAS). He then learned of a novel technology in which feed is made from the fish's own waste and fed back to the fish.

He involved his engineer son and his son's friend in training and research on the new method called biofloc. Now Tahsin and Aminul, two computer engineers of this generation, are fully engaged in fish farming.

By their reckoning, the new method is much more promising and profitable. With relatively small investment, this science-based method could attract new entrepreneurs.
