ABSTRACT:
Water from a fish growth tank is pumped through multiple filter tanks containing a filter media and injected with ammonia fixing bacteria. Metabolic wastes from the fish growth tank are absorbed by hydroponic or sand growth beds. Oxygen content and temperature of the water is constantly monitored by sensors and air blowers and heaters are activated when oxygen level or temperature respectively falls below the prescribed conditins for growth of the fish. All backwash water from a sludge digestion area is recirculated to the fish growth tank to conserve water in the system.
