Character of the water

Kotjärnen lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 5 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.

Moderately deep (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Kotjärnen FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Kotjärnen

perch predatory fish
typically ~22 cm · can reach 45 cm
The nutrient-rich water keeps perch moving constantly between the feeding grounds.
pike predatory fish
typically ~62 cm · can reach 120 cm
Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
roach coarse fish
typically ~18 cm · can reach 32 cm
The nutrient-rich water keeps roach moving constantly between the feeding grounds.
bream coarse fish
typically ~38 cm · can reach 65 cm
Bream works the bottom in the dark — smell and feel come before everything else.

Fishing Kotjärnen

Kotjärnen holds 4 species, with perch and pike at the top of the chain and roach and bream schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

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 Kotjärnen are alike.

General rules of thumb for this kind of water

  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
