136622 Brown Trout Salmo trutta Length 30-50cm
This familiar sport fish is known in two forms: the Brown Trout, which spends its entire life in freshwater; and the so-called Sea Trout, which only ventures up rivers to breed. Both forms spawn in gravel beds in shallow water. An adult Brown Trout has an orange-brown body adorned with red and black spots; a Sea Trout is pale and silvery with a few dark spots. Brown Trout are widespread and often common in fast-flowing unpolluted rivers and streams. Sea Trout are scarce and declining, found mainly in the W and NW of Britain.
