Character of the water

Långsjön lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 8 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.

A small but surprisingly deep pocket (12 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

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

  • Pike: keep at most one over 75 cm per day.
  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Långsjön

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.
burbot bottom fish
typically ~45 cm · can reach 90 cm
Down on the bottom burbot sifts the soft ground — patience beats speed here.
roach coarse fish
typically ~18 cm · can reach 32 cm
The nutrient-rich water keeps roach moving constantly between the feeding grounds.
trout salmonids
typically ~35 cm · can reach 70 cm
Trout hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
vendace whitefish
typically ~16 cm · can reach 28 cm
Vendace follows the schools through open water — here today, gone tomorrow.

Fishing Långsjön

perch, pike and burbot sit at the top of the food chain in Långsjön, carried by roach and vendace. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.

Whoever fishes Långsjön 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.
