🐟Brown trout

Salmo trutta Linnaeus, 1758

The brown trout is a species of carnivorous ray-finned fish and the most widely distributed species of the salmonid genus Salmo, endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range.
