Interpretive Summary:

Technical Abstract: High yields are obtained from an outdoor biofloc technology (BFT) production system in response to high stocking and feeding rates because the biofloc, which is maintained in suspension by continuous aeration, metabolizes excreted feed nitrogen (N). Penaeid shrimp and tilapia are grown in the BFT system because they can derive some nutrition from consuming the biofloc. For fish like the channel catfish, which derives little or no nutrition from the biofloc, the BFT system is a water quality management tool that permits production intensification and increased water use efficiency. We investigated channel catfish production, water quality and phytoplankton dynamics, and common off-flavors in a series of production experiments conducted in outdoor, 18.6-m2 tanks.
