To ensure in future an sufficient oxygen level, even at temperatures of 40 and more °C are measures necessary to enrich the water with oxygen. This can be done by pumping air into the water or by recirculating water (movement) and increasing the active surface to allow and increased oxygen intrusion. Currently is a solar driven water pump system installed on the farm - the panels allowing a capacity of 2 kWpel. The plant operates solely under sunshine. The sun impact during the day is responsible for an increase of the temperature of the water in the fishpond and a lowering of the oxygen saturation.
