Aquaponics is a system defined as the combination of aquaculture and hydroponics in which both are done at the same time. In this process, aquatic wastes are taken out from the pool water to refuse the contamination of the aquatic live environment and used for plants. Then, the water refined by the plants is used again in the cycle.

Despite the desire of this idea, applicability of aquaponic systems in this manner is not commercial. Unbalanced soluble nutrients and not proper pH of the solution for plants, likely microbial contamination of aquatic wastes in one hand and the chemical contamination of drained water from the plants root and its bad effect on aquatic feed on the other hand, make the uncontrolled aquaponic system of production not commercially practical.

In order to implement an aquaponic system, the pools might be built in the bed of greenhouse and the cultivation bed structures can be installed vertically between the pools. Guaranteed enough light with the least waste of energy of heating can be provided by transparent polycarbonate sheets while auxiliary light may be obtained by full spectrum LEDs. The last but not the least important note about the aquaponic systems is that permanent, accurate, and precise control of environment parameters (temperature, humidity, light, oxygen, carbon dioxide, and other gases) and water (temperature, acidity (pH), electrical conductivity (EC), nutrient concentration, microbial contamination, oxygen, and carbon dioxide) is essential for the system manager; however, it is assumed that all the employees working there are skilled.
