Bio-floc Technology (BFT) is considered as new “blue revolution” since nutrients can be continuously recycled and reused in the culture medium, benefited by the minimum or zero-water exchange. BFT is an environment friendly aquaculture technique based on in-situ microorganism production. The method of Bio-floc Fish Farming cuts all the major costs so that the saving can be really big. Several factors such as huge operational costs, costs of vast lands, high-cost feeding, disposal and discharge of waste sludge will not be problems when you opt for this method.
