Biotope presentation
The acidification of water comes from the decomposition of plants. This phenomenon changes the color of the water, which tends to turn brown. In some areas particularly rich in organic matter, the water is so dark that it is called "black water".
The brown trout prefers well oxygenated waters in current areas and rapids. It frequents fast flowing waters where the bottom is strewn with pebbles, wood or leaves carried by the current. It can be found not far from waterfalls .
