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".
Oncorhynchus mykiss is most often found at a depth between 0m and 200m. However, it is not impossible to find this species at other depths.
