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. [1]
Recirculating aquaculture system. Recirculating aquaculture systems ( RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [ 1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a ...
In earlier aquaponic systems, the media often became clogged or resulted in uneven fertigation, which hindered their efficiency and effectiveness. [ citation needed ] The development of the reciprocating biofilter, where filter beds are alternately flooded and drained, has significantly mitigated issues such as clogging, channelization, and low ...
A biofilter is a bed of media on which microorganisms attach and grow to form a biological layer called biofilm. Biofiltration is thus usually referred to as a fixed–film process. Generally, the biofilm is formed by a community of different microorganisms ( bacteria, fungi, yeast, etc.), macro-organisms ( protozoa, worms, insect's larvae, etc ...
Trickling filter. A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime ( biofilm) to grow, covering the bed of media.
Intended to save species in the event of a disaster on Earth, the plan makes use of craters that are permanently in shadow and therefore cold enough to allow cryogenic preservation of biological ...
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 ...
Integrated multi-trophic aquaculture. Blue mussels ( Mytilus edulis) cultivated in proximity to Atlantic salmon ( Salmo salar) in the Bay of Fundy, Canada. Note the salmon cage (polar circle) in the background. Integrated multi-trophic aquaculture ( IMTA) is a type of aquaculture where the byproducts, including waste, from one aquatic species ...
