The surroundings

Shallow throughout (max 3 m), with reeds and vegetation over large areas — water that warms fast in spring.

Species in Grinnsjön
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.
Fishing Grinnsjön
perch and pike sit at the top of the food chain in Grinnsjön, carried by ål. 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 Grinnsjön are alike.
