Brown Trout - Salmo trutta

Alternative names
Sea Trout

Freshwater Brown Trout range in colour from largely silver with relatively few spots and a white belly, to the more well-known brassy brown, fading to creamy white on the fish's belly, with medium-sized spots surrounded by lighter halos.

Identification difficulty

Rivers, streams, lakes and even saltwater (see ‘Life History’ below)

When to see it

All year round.

Life History

Sea Trout and Brown Trout are the same species. A combination of genetics and environmental factors (principally lack of food), will mean that some trout will go to sea to feed before returning to spawn. This is called an ‘anadromous’ lifestyle.

UK Status

Widespread and fairly frequent in Britain. Red Data Book species.

VC55 Status

Fairly frequent in Leicestershire and Rutland.Found in the cleaner rivers and streams, including the upper Soar, Chater and western Sence; mainly introduced/restocked in lakes and rivers, the pure native breeding populations (Salmo trutta fario) probably only surviving in fast flowing streams in Charnwood Forest.
