Aquaponic systems are recirculating aquaculture system that incorporate the production of plants without soil. Recirculating system are designed to raise large quantities of fish in relatively small volumes of water by treating the water to remove toxic waste products and then reusing it. Plants grow rapidly in response to dissolved nutrients that are excreted directly by fish or generated from microbial breakdown of fish wastes.
