Character of the water

Bockatjärnen lies in the south — a southern acidified forest lake. In summer a thermocline settles around 6 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 (10 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

perch predatory fish
typically ~22 cm · can reach 45 cm
Perch moves carefully in the clear water — small mouthfuls, many of them.
ål fish
typically ~55 cm · can reach 110 cm
Ål holds the bottom even in clear water — shade and depth are its cover.
pike predatory fish
typically ~62 cm · can reach 120 cm
In the clear water pike picks its moments — wary, but relentless once committed.
roach coarse fish
typically ~18 cm · can reach 32 cm
Roach moves carefully in the clear water — small mouthfuls, many of them.
sutare fish
typically ~35 cm · can reach 60 cm
Sutare lives down in the cool — the deep is its home ground all year.

Fishing Bockatjärnen

Bockatjärnen holds 5 species, with perch and pike at the top of the chain and ål, roach and sutare schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Every session at Bockatjärnen is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

General rules of thumb for this kind of water

  • Acidified water yields few, hardy species.
