Biofloc technology in aquaculture and its potentiality: A review


Author(s): MA Halim, S Nahar and MM Nabi

Abstract: The ever increasing population of Bangladesh demands for more intensive production from aquaculture without sacrificing the quality. However, managing the wastes from aquaculture has become an emerging issue for environmental safe guard. So the expansion and intensification of aquaculture will need to take place in a sustainable way. Biofloc technology (BFT), the new “blue revolution” in aquaculture, could be promising in attaining this sustainability. It is mainly based on the principle of waste nutrients recycling, in particular nitrogen, into microbial biomass that can be used in situ by the cultured animals or be harvested and processed into feed ingredients. Such technique is based on in situ microorganism production which plays three major roles: (i) maintenance of water quality, by the uptake of nitrogen compounds generating in situ microbial protein; (ii) nutrition, increasing culture feasibility by reducing feed conversion ratio (FCR) and a decrease of feed costs; and (iii) competition with pathogens. The potentiality of biofloc in aquaculture will be discussed in this review.
