Four lakh into biofloc tanks, 60,000 taka of fish sold

This farmer in Thakurgaon took biofloc training in Narayanganj and set up two tanks at home, spending about 400,000 taka on tanks, tarpaulin, fingerlings and electrical equipment. He stocked koi fingerlings first, but the fry were of poor quality and 18,000 to 19,000 of them died. He restocked, and a sudden flood then carried many of the fish away, because nothing had been built to drain the water. He switched to tilapia, again could not get good fingerlings, and the market price was low. Across the two rounds the fish alone cost 180,000 taka, while the electricity bills for the aeration motors ran high. In the end he sold only 60,000 taka worth of fish, then sold off the equipment and shut down the operation, one of about 30 biofloc farms in Thakurgaon Sadar upazila at the time.
