Character of the water

Alsjön lies in central Sweden — a acidified forest lake. 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 (15 m) — shallow bays, the odd reef and a deeper channel through the middle.

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.

Fishing Alsjön

Alsjön holds 15 species, with perch, pike and zander at the top of the chain and ål, björkna and bream schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Whoever fishes Alsjön 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

Acidified water yields few, hardy species.
