Character of the water

Kojtjärnen lies in the cold north — a northern mesotrophic stratified lake. In summer a thermocline settles around 6 m and splits the lake into two worlds.

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.

A small but surprisingly deep pocket (14 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Kojtjärnen FVOF. Day permit ~100 kr · annual permit ~500 kr.

  • Zander: minimum size 45 cm · protected during the spawn (Apr–May).
  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Kojtjärnen

perch, pike and zander sit at the top of the food chain in Kojtjärnen, carried by roach and ruffe. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Kojtjärnen is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.
