Character of the water

Mosjön lies in central Sweden — a acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. 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.

A small but surprisingly deep pocket (21 m) with steep drops straight down from shore — the bottom falls away fast.

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

Pike: keep at most one over 75 cm per day.
Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
Handheld tackle only. Respect the protected zones at the inlets and outlets.

In the murky light, pike shadows the baitfish and hits in short rushes.

grayling fish

typically ~30 cm · can reach 50 cm

Grayling grazes the rich water in schools — where there's one, there are more.

Id grazes the rich water in schools — where there's one, there are more.

Fishing Mosjön

Mosjön holds 13 species, with perch, pike and grayling at the top of the chain and bream, elritsa and id schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

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 Mosjön are alike.

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.
In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
Acidified water yields few, hardy species.
