Fishing Flatasjön
perch, pike and zander sit at the top of the food chain in Flatasjön, carried by roach, bream and ruffe. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.
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 Flatasjön are alike.
General rules of thumb for this kind of water
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
