Using BioFloc Technology to Improve Aquaculture Efficiency

Year: 2025

Type: article

Abstract: In the present study, literature information on the functioning of the biofloc technology (BFT) system, its components, the state of the organism of hydrobionts, and water quality is analyzed. It is shown that this technology allows reducing financial costs for water treatment by 30%, increasing the efficiency of protein assimilation in the feed composition by two times, and creating a high-protein substrate, which can be further used as a component of feed for aquaculture. The BFT contains a large number of microorganisms, including photoautotrophic microorganisms (algae), chemoautotrophic microorganisms (nitrifying bacteria), and heterotrophic microorganisms (fungi, infusoria, protozoa, and zooplankton). This technology contributes to the improvement in water quality, aquaculture productivity, and hydrobionts. Despite the higher initial costs, BFT can yield higher economic profits. In this paper, the authors summarize data from many recent studies devoted to BFT. Based on the analysis of a number of studies, it can be concluded that this technology has a high potential for scaling up in industrial aquaculture.
