Ecology

Grayling in a sunny pool

The Allier is one of the rare places in southern Europe where the freshwater grayling (Thymallus thymallus), known in French as ombre des rivières, occurs in a natural habitat.^[5]

Grayling like to live in shoals and are sensitive to pollution. In the Allier these fish are more abundant in the stretch between Langogne and Brioude. They are economically important, being appreciated for food and fished for sport.
