Production of aerobic, anaerobic and anoxic bioflocs from tilapia sludge

Abstract: Bioflocs produced in suspended growth bioreactors under aerobic, anaerobic and anoxic conditions could offer the fish feed industry a novel alternative feed. In this study, an experiment involving incubation of sludge in aerobic, anaerobic and anoxic systems for 22 days was conducted. The experiment was carried out in 9 glass aquaria tanks that were used as reactors for daily sludge incubation. These reactors were fed tilapia manure. Aerobic, anaerobic and anoxic conditions were confirmed by measurement of redox potential, pH, temperature, NO3 and O2 concentration. We succeeded in creating the right environmental conditions for biofloc development.
