Fishing Grossbosjön
perch, pike and zander sit at the top of the food chain in Grossbosjön, 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 Grossbosjön are alike.
