The lake trout - Salmo trutta lacustris caught in a small lake in the Rogen nature reserve.
The lake trout spawns and grows up in running water, after which it spends its entire adult life in lakes. A rare color form with a dark head, a beautiful golden back and ten red "blood spots" on each side, which lives in Rogen's many ponds and small lake waters formed during the Ice Age. A fully grown specimen here at two kilos, adapted to a life in dark ponds - hence the dark colors.
