Character of the water

Ösbyträsk lies in central Sweden — a clear oligotrophic forest 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 (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Ösbyträsk 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.

Fishing Ösbyträsk

The species list of Ösbyträsk runs to 6. The predators — perch, pike and zander — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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 Ösbyträsk are alike.

General rules of thumb for this kind of water

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
