Character of the water

Koiransuolijärvi lies in the cold north — a northern acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. 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 — Koiransuolijärvi 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 Koiransuolijärvi

perch predatory fish
typically ~22 cm · can reach 45 cm
Perch moves carefully in the clear water — small mouthfuls, many of them.
pike predatory fish
typically ~62 cm · can reach 120 cm
In the clear water pike picks its moments — wary, but relentless once committed.
vendace whitefish
typically ~16 cm · can reach 28 cm
Vendace cruises the open water — the depth it picks follows the light through the day.

Fishing Koiransuolijärvi

Koiransuolijärvi holds 3 species, with perch and pike at the top of the chain and vendace schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

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 Koiransuolijärvi are alike.

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.
