Description

The brown trout is a salmonid of the family Salmonidae that can reach about 140 cm as a sea trout but is usually much smaller. The streamlined body bears an adipose fin and is scattered with black and often red, halo-ringed spots; the colour ranges from brown-gold to silvery in sea-run fish. The species is native to cool rivers, lakes and coastal waters of Europe, North Africa and western Asia and has been stocked worldwide for angling. It is a predator hunting insects, crustaceans and small fish. In autumn it moves to gravelly headwaters to spawn, where the female digs a pit and lays the eggs in the gravel.
