Salmo trutta (Brown trout)


Wikipedia Abstract

Salmo trutta morpha fario is the riverine form or the brown trout Salmo trutta that spends its entire life cycle in running water. While previously considered a distinct subspecies or even species, it is currently not considered to be taxonomically different from other ecological or migratory forms of the brown trout, i.e. the sea trout (Salmo trutta morpha trutta) or the lacustrine brown trout (Salmo trutta morpha lacustris). 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). They usually attain a weight of up to 2 kilograms, but sometimes up to 13 kilograms (29 lb). Their back is olive-dark brown and silvery blue, red spots with light edges occur towards the belly, th
