About

The brown trout is a remarkably adaptable salmonid native to Europe and western Asia, now established on every continent except Antarctica. Sea-run individuals (called sea trout) transform from golden-spotted river fish into bright silver oceanic predators and back again — the same species, completely different appearance.
