Character of the water

Ljustjärnarna lies in central Sweden — a acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 4 m and splits the lake into two worlds. Acidification has thinned life down to the hardiest few.

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

Permits & rules

Fishing permit required — Ljustjärnarna 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.
  • 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.

Fishing Ljustjärnarna

perch, pike and zander sit at the top of the food chain in Ljustjärnarna, carried by bream, ruffe and id. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Whoever fishes Ljustjärnarna 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
  • Acidified water yields few, hardy species.
