Microcontrollers in Recirculating Aquaculture Systems

Closed-system aquaculture presents a new and expanding commercial opportunity; however, presently there are few profitable commercial operations. Intensive aquaculture systems require a sufficient supply of oxygen and nutrients in temperaturecontrolled water with a means of removing wastes from the system. In properly controlled recirculating aquaculture systems, stocking rates of up to one-half pound of fish per gallon of water can be obtained. However, since failure of any component can cause catastrophic losses within a short period of time, the system must be reliable and constantly monitored. Thus, precise measurements and controls are necessary for the success of an intensive recirculating aquaculture system.
