The fario morph is often referred to as river trout in Europe. Riverine brown trout average 20 to 80 centimetres (7.9 to 31.5 in) but can reach lengths of 1 metre (3.3 ft).

Invasive Species

Salmo trutta has been introduced around the world for aquaculture and stocked for sport fisheries. It is blamed for reducing native fish populations, especially other salmonids, through predation, displacement and food competition. It is a popular angling fish.
