Character of the water

Grösjön lies in the south — a southern humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.

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.

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

Permits & rules

Fishing permit required — Grösjön 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 Grösjön

perch predatory fish
typically ~8 cm · can reach 41 cm
The nutrient-rich water keeps perch moving constantly between the feeding grounds.
bream coarse fish
typically ~32 cm · can reach 43 cm
Bream works the bottom in the dark — smell and feel come before everything else.
pike predatory fish
typically ~53 cm · can reach 64 cm
Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
roach coarse fish
typically ~14 cm · can reach 27 cm
The nutrient-rich water keeps roach moving constantly between the feeding grounds.
sarv fish
typically ~13 cm · can reach 28 cm
Sarv grazes the rich water in schools — where there's one, there are more.

Fishing Grösjön

perch and pike sit at the top of the food chain in Grösjön, carried by bream, roach and sarv. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Whoever fishes Grösjön 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
