Aquaponics – the combined method of growing fish and plants.
Aquaponics – the combined method of growing fish and plants together in a recirculating ecosystem using natural bacterial cycles to convert fish waste into nutrients for plants.
Aquaponics – the combined method of growing fish and plants together in a recirculating ecosystem using natural bacterial cycles to convert fish waste into nutrients for plants. It is an environmentally friendly method that uses the best attributes of aquaculture and hydroponics without the need to add chemical fertilizerto throw water or filtrate.
Aquaponics can be called the combination of the other two cultivation methods: hydroponics and aquaculture. Aquaculture needs to be provided with permanent waste disposal, not permitting achievements toxic to fish level. Hydroponics requires constant replenishment and manual balancing of chemicals.
Aquaponics is an eco system created by artificial means, but on the basis of natural processes. Its key elements are:
– the aquatic fauna (fish, shellfish, etc.);
– aquatic flora (algae);
natural microorganisms (bacteria).
Such natural processes necessary for the quality of growing fish, as the last in the cycles of their life synthesize various compounds of nitrogen, calcium, phosphorus, and carbon dioxide. An excessive amount of such substances in a small enclosed space (regardless of whether the pool is for the production of a culture or an indoor aquarium) makes the environment dangerous, contaminates all living organisms that is the main problem of the fishing industry. However, all of these substances are essential for plant growth, which provides the technique in aquaponics all waste products of the fish are utilized by microorganisms and flora in the end, underwater animals receive a quality plant food and pure filtered water.
– a more intensive aeration of water as the basis for the development of plants,
– easy flow of all minerals and the microcells necessary for growth and reproduction of plants, freshwater creatures and bacteria
double result of management activities: harvest crops and product from the fisheries,
– avoiding harmful herbicides, pesticides and other chemicals, which means the ecological purity of the crop
– save money on food fish by feeding them parts of plants,
– savings on plant nutrition due to symbiosis with fish and recovery of wastes of life last
– maximum water recycling allows to economize on this resource, reduces or neutralizes the wastewater,
– high quality and reinforced ventilation water, enriching it with oxygen several times more than the application of other methods of oxygen enrichment,
– a simple method of supplying essential micro-and macroelements, without which no proper and full life of underwater flora and fauna,
– exclusion from the production process of synthetic fertilizers, based on a combination of chemical elements, i.e. the cultivation of environmentally friendly products,
– reduction of production costs due to the partial cessation of purchases of fish feed (they are the grown plants),
– continuous and high quality water filtration saves her permanent replacement and reduces the risk of contamination of the natural pools due to draining the dirty liquid into drains.
Aquaponic systems are usually grouped into several components or subsystems responsible for the effective removal of waste, addition of bases to neutralize acids, or for the enrichment of water with oxygen. Typical components include:
– the tank for breeding: tanks for breeding and forage fish;
– sump: a unit for catching uneaten feed, separated biofilm and to separate fine particles;
– biofilter: a place where the nitrification bacteria can grow and convert ammonia into nitrates needed for plants;
– hydroponics subsystem: the portion of the system where plants are grown by absorbing excess nutrients from the water;
– sump: the lowest point in the system where water enters and from which it rises back into the tanks.
Depending on the complexity and cost aquaponic system capacity waste, biofilters and/or hydroponic subsystems can be combined into a single section or subsystem which prevents the flow of water from the aquaculture part of the system to the hydroponics part.
Additionally, aquaponic system can present the elements necessary for better elimination of waste water or those where the additionally introduced mixture, promoting more rapid neutralization of nitrogen compounds, filters, faster cleansing water and so on. However, the main such components are intended to improve, modernize natural processes, aimed at obtaining faster results from production.
