Fish from natural Swiss waters cannot meet consumption needs by far. 94% of the fish consumed in Switzerland are imported. The annual approximately 3000 t domestic fish production corresponds to approx. 6% of the total fish consumption resp. about 25% of the freshwater fish consumed. Only about 1200 t of fish come from domestic farming, the greater part is supplied by professional fishermen. So there is a big demand here, which is not (yet) met.
