Due to the depleting phosphorous and freshwater reserves and increasing requirement of sustainable food production methods, the popularity of aquaponics is surging rapidly across the world. Furthermore, the rising environmental concerns raised over the large-scale usage of pesticides, insecticides and artificial nutrients in the conventional farming methods are boosting the demand for aquaponics in several countries all around the world. Moreover, aquaponics has numerous advantages over the traditional farming techniques such as lesser requirement of water and negligible usage of artificial fertilizers and chemicals, owing to which, it is being highly sought after across the globe.
Due to the above-mentioned factors, the global aquaponics market is expected to register considerable growth during the forecast period (2020—2030). Aquaponics is defined as a system that integrates aquaculture (farming of aquatic animals such as fish, prawns, and snails in tanks) with hydroponics (the cultivation of plants in water) in a symbiotic environment where the water from the aquaculture system is supplied to the hydroponic system, wherein, the by-products are broken down into nitrates and laterconsumed as nutrients by the plants.
There are multiple types of aquaponic systems used throughout the world— nutrient film technique (NFT), media-filled beds, and deep-water culture. Out of these, the media-filled beds recorded the highest utilization in 2019. This is mainly attributed to the fact that the media-filled beds have a very simple form and are thus, highly sought after all over the world over the other systems. In addition to this, in the media-filled beds, the plant roots are periodically exposed to air, which plays a major role in preventing waterlogging.
