With the ever-growing human population, a significant expansion has been observed in worldwide aquaculture throughout the last ten years. The successful administration of prime conditions for fish production depends entirely on the physicochemical and biological quality of the water. Consequently, emphasizing research dedicated to elucidating both water quality aspects and the long-term viability of aquaculture operations holds considerable significance. Biofloc Technology (BFT) employs microbial methods to enhance the performance of aquaculture operations. This strategy centers on the prolific cultivation of microalgae, that this in turn fuels the fish, leveraging these tiny organisms. The process effectively transforms hazardous components like nitrogen into beneficial resources, like protein, subsequently available for consumption. However, Biofloc presents a promising approach for aquaculture, enabling the establishment of systems with minimal or no water replacement. This method facilitates the cultivation of fish at elevated densities, and relies on robust aeration combined with the presence of living biomass within the environment. The primary focus of this research centers on the significant contributions of biofloc technology. We delve into its operational processes, specifically how it provides a beneficial food source, aids in the improvement of water quality, and addresses the problematic buildup of nitrogen and ammonium compounds. In conclusion, the most current scientific investigations concerning the effectiveness of biofloc systems within the context of aquaculture will be examined.
