Character of the water

Tannsjön lies in the cold north — a northern nutrient-rich lowland lake. In summer a thermocline settles around 10 m and splits the lake into two worlds.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Large and deep (21 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Permits & rules

Fishing permit required — Tannsjön FVOF. Day permit ~60 kr · annual permit ~300 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.

Species in Tannsjön

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.
zander predatory fish
typically ~50 cm · can reach 95 cm
Zander hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
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 Tannsjön

Tannsjön holds 5 species, with perch, pike and zander at the top of the chain and roach and bream schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

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 Tannsjön 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.
