Diffusers built into the basins oxygenate the water from the floor (foreground), while a mechanical aerator (background) performs the same job at the surface.
Hodowla Ryb K-2 combines a recirculation system with the generous use of water
Farming and processing trout for the Polish market At Hodowla Ryb K-2, trout are farmed intensively using a sophisticated recirculation system. Currently 400 tonnes of trout a year are produced on the farm, a ďŹ gure that is soon due to rise to 600 tonnes.

the farm. Production is intended to reach 700 to 800 tonnes a year, but this target will not be reached in 2016, he says, as temperature fluctuations in the water that supplies the farm have affected the volumes produced. The water is drawn from a river running by the farm and although it is recirculated through the system this has little impact on the temperature which tends to be the same as in the river. The farm also has access to some groundwater, which has a constant temperature, but it is only a secondary source and cannot supply all the sections of the farm. The advantages of using groundwater are so marked that the company will be looking
