Fish farm waste water research. Farmed trout in waste water tanks as part of a pilot project on their use in waste water treatment systems. Fish can feed on the plankton produced in the later stages of waste water treatment systems. This project is part of the PEIMA experimental fish farm (Pisciculture Experimentale INRA des Monts d'Arree) in Sizun, Finistere, Brittany, in north-western France. INRA is the French national agronomy research institute. Photographed in 2011.
