Fishing Grässjön
perch, pike and burbot sit at the top of the food chain in Grässjön, carried by bream, ruffe and roach. 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 Grässjön 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.
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
