Aquaponics:
Aquaponics is a system of a combination of conventional aquaculture with hydroponics in a symbiotic environment, in which plants are fed with the aquatic animals’ excreta or wastes.

• These wastes are broken down by nitrifying bacteria initially into nitrites and later into nitrates that are utilized by the plants as their nutrients.
• Thus the wastes are utilized and water is recirculated back to the aquaculture system.
