Fishing Östra Marssjön
perch, pike and grayling sit at the top of the food chain in Östra Marssjön, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Östra Marssjön are alike.
General rules of thumb for this kind of water
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
