iAVs schematic diagram Tomato transplants in a biofilter (composed of sand, bacteria and plants) shown being irrigated with aquacultural water for the first time.. The Integrated Aqua-Vegeculture System (iAVs), also informally known as Sandponics, [1] is a food production method that combines aquaculture and horticulture (olericulture). [2]
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.

Aeroponics has made significant advancements in tissue culture technology, enabling faster plant cloning and reducing the labor-intensive steps associated with traditional tissue culture techniques. One of the notable benefits of aeroponics is its ability to eliminate the need for stage I and stage II plantings into soil, which has been a ...
[6] [7] However, there are issues with the reliability of the reported figures. [8] Further, in current aquaculture practice, products from several kilograms of wild fish are used to produce one kilogram of a piscivorous fish like salmon. [9] Plant and insect-based feeds are also being developed to help reduce wild fish been used for ...
