🎣 Sea trout

The migratory form of brown trout, essentially the same species that has run out to sea and returned, known among specialists for hard-fighting, often nocturnal sport.

Bright silver when fresh from the sea, with fewer, smaller black spots than a resident brown trout and a more deeply forked tail. Colouring darkens the longer a fish has been back in freshwater.

Found in coastal rivers around the UK, particularly in Wales, the West Country, Scotland and Ireland-facing coasts, running up from estuaries to spawn. Much sea trout fishing is done after dark, when the fish are at their most active in low water.
