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.
The Integrated Floating Cage Aquageoponics System (IFCAS) was developed as an aquaculture-horticulture based on the concept of integrated farming system approach firstly in Bangladesh in 2013 to produce fish and vegetables in floating condition where waste materials (fish feces and unused feed) from fish culture dissolved in the pond water and settled on the bottom mud are used for vegetables ...
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.
In an aquaponics system fish effectively fertilize the plants, this creates a closed looped system where very little waste is generated and inputs are minimized. Aquaponics provides the advantage of being able to harvest and sell multiple crops. Contradictory views exist on the suitability and safety of RAS effluents to sustain plant growth ...

Most commercial DWC systems are designed to grow leafy greens such as head lettuce, baby leaf greens, large leaf greens, and herbs. One may also find facilities that utilize DWC to grow hemp and other produce, however, this is less common. Depending on what type of produce is being grown, the system design and horticultural techniques will change.
A run-to-waste hydroponics system, referred to as "The Bengal System" after the region in eastern India where it was invented (circa 1946) This method can be set up in various configurations. In its simplest form, a nutrient-and-water solution is manually applied one or more times per day to a container of inert growing media, such as rockwool ...
Lettuce grown in indoor vertical farming system. Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [1]
