Scientific Name: Salmo trutta
 UK Status: Native

Quick Facts

Identification

Brown Trout vary in colour depending on their environment but are generally golden-brown to olive with dark spots and distinctive red or orange spots surrounded by pale halos.

They have a streamlined body and slightly forked tail. River fish are often slimmer, while stillwater trout can appear deeper-bodied.

Sea-run forms (sea trout) are silver when fresh from the sea.

Habitat & Behaviour

Brown Trout thrive in clean, well-oxygenated water. In rivers and streams they favour deeper pools, undercut banks, and areas with cover. In lakes and reservoirs they may patrol margins or deeper water depending on temperature and food availability.

They are opportunistic predators, feeding on aquatic insects, crustaceans, and small fish. Larger specimens become increasingly predatory.
