Sea Trout (Salmo Trutta Trutta)
Where to Find Sea Trout
This map shows global observations of sea trout, helping you identify the continents, countries, and waters where this species thrives.
Dubbed "the fish of 1,000 casts," sea trout can discourage even seasoned fly fishers. Their unpredictable nature—knowing where and when they’ll appear—separates dedicated anglers from casual enthusiasts. Yet, with the right research, knowledge, and gear, landing a sea trout can transform from a distant dream into a rewarding reality.
The sea trout is the wanderer of the trout family. While brown trout remain in their home waters year after year, sea trout migrate to the ocean to feast on crabs, shrimp, and small fish before returning to freshwater to spawn.
Their vast habitat and abundant food supply result in both large fish and erratic movements. Predicting where an incoming tide will deposit them is a challenge—getting it right every third attempt is an achievement.
If night fishing isn’t your preference, don’t worry. Sea trout are occasionally caught during daylight, but success demands exceptional stealth: stay hidden, and present your flies with precision.
How to Fly Fish for Sea Trout
Since sea trout become harder to catch the longer they stay in freshwater, target fresh-run fish after a flood, once the water clears.
During the day, they rest in slow, deep pools beneath overhanging trees. At dusk, listen for splashing—they’re on the move, heading upstream through shallower sections. They often pause in deep pools before continuing at dawn, though some remain in pools all night.
In shallow waters, fish your fly fast and near the surface. For pools, switch to a sinking line and retrieve a lure slowly along the bottom.

Best Flies for Sea Trout
Like salmon, sea trout stop eating once they enter freshwater, yet they inexplicably strike certain flies. Traditional wet flies in sizes 6–12, such as the Butcher, Dunkeld, Invicta, and Mallard and Claret, are effective. Fish two flies together, with the larger on the dropper, and let the current do the work. Move downstream after each cast to cover more water.
In saltwater, focus on shrimp patterns and small baitfish imitations.
