A recirculating aquaponic system on DWC type floatable support was carried out during the research activities carried out at ICDIMPH-Horting Bucharest in the period 2017-2021. It works on the principle of communicating vessels and satisfies the technological needs of fish and plant breeding. The system was placed in a micro-greenhouse made of polyethylene foil, according to a plan for the location of technological equipment, by reconditioning and arranging tunnels for growing of grafted plants. The construction included tunnels with a length of 7.40 m and a width of 1.81 m (fish growth tunnel, 70 cm high, made of 20 mm thick OSB boards, mesh and durable foil, 8 rectangular basins, with holes for aeration, water supply and drainage and inside two layers of ultra-additive foil, 0.2 mm thick and and tunnels for growing plant material), reconditioned by mounting a protective foil, attached in PVC clips to the skeleton of the tunnel and the base of the pools with an inclined slope of 5-10% for draining water and residues), installations, pumps, filters. It has been tested for growing carp (Cyprinus carpio) and lettuce (Lactuca sativa). Fish waste have been food for plants, and plants have naturally filtered water for fish, phytosanitary treatments with synthetic substances have been eliminated, lettuce obtained has had from quality categories I and II, the fish has had hematological parameters in the reference ranges indicated in the speciality literature for carp.
