Aquaculture has become vital to global food security, offering a sustainable protein source to meet the increasing population's demands. Innovative aquaculture systems like Biofloc Technology (BFT) have been developed to address several challenges of traditional aquaculture practices, including high resource use, environmental pollution, and disease management. BFT enhances water quality, reduces feed costs, and improves overall sustainability. Adequate aeration is responsible for the success of biofloc systems, which plays a crucial role in maintaining optimal conditions for both the cultured organisms and the biofloc itself. This article explores the importance of aeration in biofloc systems and its mechanisms, benefits, and practical considerations.
