Biofloc Technology
open-in-new
<p>Biofloc technology (BFT) is a system of <a href="/facts/Aquaculture/MYdIMfbt">aquaculture</a> that uses "microbial biotechnology to increase the efficacy and utilization of fish feeds, where toxic materials such as nitrogen components are treated and converted to a useful product, like a protein for using as supplementary feeds to the fish and crustaceans." </p><p>In high nitrogen environments, the beneficial <a href="/facts/Heterotroph/wtzlgBtz">heterotrophic</a> bacteria are typically limited by carbon levels. Therefore, adding a readily available source of carbon allows the bacteria to simultaneously take up a greater portion of nitrogen (contributing to better water quality) as well as generate biomass that then serves as food for the cultured animals. </p><p>The species of <a href="/facts/Fish/fln4gH9V">fish</a> and <a href="/facts/Crustacean/PBobIVJP">crustaceans</a> must be carefully chosen in order for the BFT system to realize its full potential. </p>
