Aquaponics is a sustainable farming systemthatcombines aquaculture and hydroponics in an environment thatissymbiotic. In aquaculture normal excretion from animals rearedinthe water will accumulate and increase the toxicity of the waterifnot disposed.

Aquaponics mimic the workings of recycling organic materialsthatoccur in nature.

- Water in aquaculture systems is that water is contaminated byfishfeces and feed residue flowed into the hydroponicsystem.
- In a hydroponic system, occurred three processes, namelysolidimpurities filtration, biofiltration and absorption ofnutrients byplants.
- The water then flows back into the aquaculture system in acleanstate.
