Aquaponie

The aquaponie is the culture of plants in “Symbiose” with fish. According to its partisans, this mode of culture was used since mists of time then forgotten until our days. They are the dejections of the fish which are used as Engrais for the cultivated plant. The word aquaponie, translation of English aquaponics, is the contraction of the words Aquaculture (intensive breeding of fish) and Hydroponique.

It is acted in fact of a ecosystem in which three types of living organisms intervene:

the fish whose dejections rich in ammonias are the source of nutrient for the plants
Of the aerobic Bactéries and anaerobes which transform ammonia into nitrate nitrites then, the latter being assimilable by the plants
the crop plants which clean the water of the aquarium by the assimilation of the roots. In practice, the water of the aquarium is pumped to be taken along in the hydroponic system, preferably a vertical NFT or a table with tide, for then turning over towards fish.

The principal stake is to find right balance between the fish population, food brought and the cultivated vegetation: A deficiency nitrogenizes some (yellowing of the sheets developing on the basis of the bottom of the plants) will be the sign of a fish subpopulation and or a lack of food. Contrary to the rate to nitrites and too high nitrates indicate that the filter on plant is ineffective and that the metabolism of these last is insufficient to cleanse the water of the dejections.

This technique is ancestral since it was used by the Mayas and the Chinese .

not to confuse with Hydroponie.
