Fish can be farmed in small spaces and indoors using the modern technology biofloc method.
Now there is no need for ponds, canals and beels for fish farming. Fish can be farmed in small space and indoors using modern technology ‘biofloc method’. Currently, fish farming has started in the backyard using this technology.
Tushar Ahmed of Sarkar Para in the Sirajganj municipal area and Ripon Sarkar of Char-Raipur village have succeeded in fish farming in this new method. They have become known as ‘the fishmonger’ in the whole district by using this low-cost biofloc method.
Seeing the success of Tushar and Ripon in fish farming using the method, educated unemployed youths of the district are showing interest in fish farming. They hope if they get government patronage, they will become “self-reliant and create employment without running after jobs”. A new horizon of possibilities for fish farming has already started in the district.
On the one hand, the demand for domestic fish is being met, on the other hand, it is becoming possible to provide non-vegetarian foods. The amount of agricultural land is decreasing every year while digging ponds. With this system, there will be no need to dig new ponds to farm this way. It is possible for fish farming in this way in a small space in the backyard and with little capital.
While talking with Tushar Ahmed, he said he inspired on fish farming after watching a video on YouTube. He later received training from Rajshahi on research on the ‘biofloc method’. At the end of the training, about a year ago, he built a room with a capacity of 90,000 liters of water at his house.
It cost me Tk 2.50 lakh. Then I started fish farming with 25 kg fry of native species of Heteropneustes, Anabas, Monosex Tilapia, Pangas fishes. It costs Tk 70,000 to buy fish fry and food and sold them in the local market for Tk 2.40 lakh, he said.
Currently, those fishes are being refarming, Tushar Ahmed said, hoping to sell “more than Tk 3 lakh of fishes” in the local market next month.
He added that the water is disinfected within 7 days of the release of fry fishes and the water is made through probiotics. The quality of the feed and water is then regularly tested. Molasses is used to control water ammonia. Fish farming should be started from the experts and with the advice of the Fisheries Office.
Sirajganj District Fisheries Officer Shahed Ali said it is possible to fish farming in a small area by biofloc method. Many people are being inspired by this method. Seeing the benefits of fish farming, many people have become more and more interested in biofloc fish farming. All kinds of overall cooperation is being provided to the interested parties.
