Aerators help suspend the bioflocs in the pond water – a main requirement for maximizing the potential of microbial processes in shrimp culture ponds. Dissolved-oxygen concentrations need to be monitored frequently to keep levels higher than 4 mg/L. Especially in biofloc systems, aerators need to be constantly monitored for malfunctions and repaired or replaced without delay, as the aerators need to operate at least 22 hours a day. The suspended biofloc must be readily
available as feed for shrimp.
