Aquaponics works best with plants that grow horizontally and whose roots grow outwards in a downward direction towards the entrance of the pump room. One benefit of aquaponics is that the plants are placed right next to the pumps, which allows for the efficient transfer of waste material from the fish tank to the beds of biofilters. Also, this arrangement facilitates for the efficient filtration and circulation of oxygenated water, and carbon dioxide from the aquaculture plants. This process also draws in other microorganisms such as nitrates from the fish waste, providing additional food source for the plants. These benefits are expected to aid in growth of the aquaponics market.
Some of the advantages of Aquaponics over conventional farming are the reduction of weeds and extra space for storing fish or livestock. However, hydroponic systems also have their limitations; especially when it comes to large scale production. For instance, in large-scale hydroponic production facilities like a duck farm, many thousands of ducks are kept in confined spaces in order to control the population of larger numbers of wild waterfowl.
