Character of the water

Stor-Kastjärnen lies in the cold north — a northern nutrient-rich lowland lake.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing permit required — Stor-Kastjärnen FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Zander: minimum size 45 cm · protected during the spawn (Apr–May).

Fishing Stor-Kastjärnen

perch, pike and zander sit at the top of the food chain in Stor-Kastjärnen, carried by roach and bream. 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 Stor-Kastjärnen are alike.

General rules of thumb for this kind of water

  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
