Character of the water

Rocksjön lies in the south — a southern acidified forest lake. 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 (8 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Rocksjön

perch predatory fish
typically ~22 cm · can reach 45 cm
Here perch lives on the small stuff — and rewards those who fish small and fine.
ål fish
typically ~55 cm · can reach 110 cm
Ål lives down in the cool — the deep is its home ground all year.
pike predatory fish
typically ~62 cm · can reach 120 cm
Pike is a sight-hunter here — the clear water means long follows before the take.
roach coarse fish
typically ~18 cm · can reach 32 cm
Here roach lives on the small stuff — and rewards those who fish small and fine.

Fishing Rocksjön

Rocksjön holds 4 species, with perch and pike at the top of the chain and ål and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Rocksjön 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

  • Acidified water yields few, hardy species.
