Aquaponika - the cultivation of fish and vegetables in symbiosis.

This article is a continuation and addition of the previous article " Breeding fish and crayfish in the suburban area "

Aquaponics (Aquaponics) - the cultivation of fish and plants in one single system and relies on natural relationships between aquatic animals and plants, which is very favorable for the preservation of the environment.

You can download video , and see this system in action (comments in English).

The system consists of two tanks located one above the other. In the lower capacity fish will live and in the upper capacity grow plants. Water to plants will be supplied with a submersible pump (pump).

And now we will examine the aquaponic system in more detail.

The products of the vital activity of fish contain nutrients for plants, but are toxic to the fish themselves. Plants absorb these substances, which provides them with the necessary nutrition, and thereby, purify water for fish (while plants and fish grow more actively). Purified water returns back to the fish, then the cycle repeats. The ground for plants in this case is the most common expanded clay or gravel.

Since plants and claydite act as a biological filter. In this regard, you can increase the amount of fish in the tank without the risk of their disease or poisoning products of life. Water is added only as far as absorption by plants, evaporation in air or removal of biomass from the system.

Waste fish are an excellent natural fertilizer for vegetables or flowers. Significantly increases yield and accelerates the ripening of fruits . In tomatoes grown on aquaponics, the content of nitrates is usually less than five to ten times higher than in the best groundwater, and the taste and aroma is in no way inferior.

Abroad, Aquaponica is already being used on an industrial scale. And we have this system is new.

The disadvantage of this system is that it is necessary to use containers for plants (fish can use an artificial pond) and electricity for submersible pumps.
