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 design and management of these systems is based on their production goals and the economics of the farming operation. [3] Aquaculture technology is varied with design and development requiring knowledge of mechanical, biological and environmental systems along with material engineering and instrumentation. [4]
STORC aquaponic's project focuses on the Urban Agriculture Method [8] studying how to reduce water use and space needed to grow food in an urban setting. The goal of the aquaponic system at the facility is to gather detailed quantitative and operational parameters creating an example for other aquaponic systems to reference.
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 ...
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 ...
Depending on what type of produce is being grown, the system design and horticultural techniques will change. For head lettuce and other large-leaf greens, seedlings are typically germinated in soilless media cells (such as rockwool or coconut coir ) and then transplanted into the floating rafts, which are usually made from low-density plastics ...
Raceway systems are among the earliest methods used for inland aquaculture. A raceway usually consists of rectangular basins or canals constructed of concrete and equipped with an inlet and outlet. A continuous water flow-through is maintained to provide the required level of water quality, which allows animals to be cultured at higher ...
