Character of the water

Stor-Mörttjärnen lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 6 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.

Moderately deep (10 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

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.
burbot bottom fish
typically ~45 cm · can reach 90 cm
Down on the bottom burbot sifts the soft ground — patience beats speed here.

Fishing Stor-Mörttjärnen

Stor-Mörttjärnen holds 6 species, with perch, pike and zander 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.

Whoever fishes Stor-Mörttjärnen regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

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.
