Koijusaarenjärvi

Character of the water

Koijusaarenjärvi lies in the cold north — a northern mesotrophic stratified lake. In summer a thermocline settles around 6 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 (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Koijusaarenjärvi FVOF. Day permit ~100 kr · annual permit ~500 kr.

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

Fishing Koijusaarenjärvi

perch and pike sit at the top of the food chain in Koijusaarenjärvi, carried by roach and vendace. The clearer water makes the fish wary — and rewards a careful presentation.

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 Koijusaarenjärvi are alike.

General rules of thumb for this kind of water

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