Conclusion The UVI aquaponic system represents an appropriate or intermediate technology that can be applied outdoors under suitable growing conditions or in an environmentally controlled greenhouse. It is ideal for areas that have limited resources such as water or level land. The system is highly productive and intense but operates well within the limits of risk. It conserves and reuses water, recycles nutrients and requires very little land. With its small land requirement it is economically feasible to locate systems close to urban markets, thereby reducing transportation costs. The system can be used on a subsistence level or a commercial scale. The system is simple, reliable and robust. Production is continuous and sustainable as demonstrated by nearly 10 years of continuous operation in its current configuration. The UVI aquaponic system does require a relatively high capital investment, moderate energy inputs and skilled management, though management is easy if production guidelines are followed.
