Biofloc Technology

Biofloc technology (BFT) is a technique used in aquaculture to balance carbon and nitrogen in a system using microbial aggregates called biofloc. The biofloc provides protein, lipids, amino acids, and fatty acids to fish. BFT aims to produce more aquaculture with minimum land and water usage through sustainable, environmentally-friendly systems. It involves limiting water exchange so organic residues accumulate and bacteria thrive, controlling water quality. Fish consume the bacteria while feed is recycled. The process requires high stocking density, aeration, lined ponds, and suitable feeding to develop biofloc over 7-15 days until it reaches the desired density above 10ml/l, at which point fish are introduced
