Sea Trout
Salmo trutta trutta
The sea-run form of brown trout — a nocturnal predator that enters rivers silver-bright and fights with extraordinary power.
Enters rivers at night from June onwards, resting in pools during the day. Requires clean coastal rivers with good sea access.
40–90 cm, typically 0.5–4 kg; specimens exceeding 10 kg are caught in Scandinavia and Ireland.
Salmo trutta trutta
Coastal rivers on both sides of the North Atlantic and around Scandinavia. Strongholds include Wales, Southwest England, Ireland's west coast, and Norway.
Sea trout offer one of fly fishing's most atmospheric experiences: wading a pool at midnight, the river glinting under a pale summer sky, presenting a fly to a fish you cannot see but know is there.
Genetically identical to brown trout, sea trout are the migratory form that leave fresh water as juveniles, spend years fattening in the sea, then return to their home river to spawn.
Fly fishing tactics
Night Fishing with Wet Flies
The traditional method on western Atlantic rivers. Fish a team of two or three soft-hackle wet flies after dark on a floating or intermediate line across and downstream.
Surface Wake Fly by Night
On still, warm summer nights over flat pools, a large muddler-style fly or small surface tube creates a wake that triggers violent reactions.
