Character of the water

Björntjärnen lies in central Sweden — a acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. Acidification has thinned life down to the hardiest few.

The surroundings

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

Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

Fishing Björntjärnen

Björntjärnen holds 9 species, with perch, pike and grayling at the top of the chain and roach, regnbåge and vendace schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Björntjärnen 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • Acidified water yields few, hardy species.
