Abstract
Biofloc technology (BFT) is an eco-friendly aquaculture approach that allows continuous recycling and reuse of nutrients in the system and reduces water exchange while providing added value resulting from microbial metabolism. The BFT system is a cutting-edge method of fish culture that is mostly used for shrimp and tilapia in India. Over time, as more people became aware of the technique, many other fish species were successfully produced in the system. BFT is one of the best system in today scenario as it help in reducing high operational cost, cost of land use, high cost of feed and discharge and disposal of waste sludge, thus minimizing water pollution. It also reduces the spread of pathogens and also improves fish health. In this article, we have given an overview of Biofloc system, fish species cultured in the system and a pilot study is also discussed.
