Besides Fish Farms, we also build Aquaponics facilities.
The Aquaponics food production system combines Aquaculture (raising fish or crustaceans in tanks) with Hydroponics (growing plants in water) in symbiotic environments. In plain aquaculture fish excretions accumulate in the water, increasing its toxicity, meaning the water must be treated before it is released back into the environment.
In aquaponics, the aquaculture waste-water is used by a hydroponic system, where by-products are broken down by bacteria into nitrites and then into nitrates, which plants can absorb as nutrients, thus reducing the cost of fertilizers. The water is naturally cleaned in the process, so it can be either re-used by the aquaculture system or released into the environment through a purifying process that is much simpler and cheaper than in regular aquaculture. The result: we produce not only fish but vegetables as well.
