Recirculating
aquaculture systems (RAS) can produce high-value species with limited water exchange rate, thus reducing waste discharge and enhancing biosecurity. Biofloc (BF) systems are a form of RAS with algae, protozoans, bacteria, uneaten feed, feces and other organic
matter in the water column. Some limiting factors to biofloc systems include abrupt changes in water quality, potential Vibrio sp. outbreaks, buildup of solids, and high energy costs attributable to robust aeration. Consumption of
biofloc particles may enhance growth performance of the cultured species and reduce feed costs over time.
