for plant use (Table 7). The data was not completed consistently enough to determine the effects of the addition of the fish and just how much nutrients they added to the system. The simplest approach to design an aquaponic system is to duplicate a standard system or scale a standard system down or up. The UVI system has been well documented and is being studied or used commercially in several locations, design for available space (Rakocy, 2006). Several different plants can be grown in this type of agriculture method. Some plants require more nutrients and require a larger density of fish to supply those nutrients. Lettuce, herbs, and specialty greens (spinach, chives, basil, and watercress) have low to medium nutritional requirements and are well adapted to aquaponic systems. Plants yielding fruit (tomatoes, bell peppers, and cucumbers) have a higher nutritional demand and perform better in a heavily stocked, well established aquaponic system (Diver, 2006). There are some advantages to growing crops in an aquaponic system over growing in the ground. Large reductions in chemical and water consumption have been achieved through the use of an aquaponic system (Rakocy, 1989). The plants act as a bio-filter, so there is no need for an separate bio-filtration system. Plus, this bio-filter produces income for the institute. There is no need for addition chemicals and fertilizers because the fish provided the nutrients for the plants. The fish waste would normally be discharged and would contribute to pollution. The removal of nutrients by the plants prolongs the water use and minimizes total water consumption. As an integrated system, it increases profit due to free nutrients, lower water requirements, elimination of a separate bio-filter, less water quality monitoring, and crops and fish can be produced in the same space and time (Rakocy et al., 2004).
