Character of the water

Kalven 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.

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

Permits & rules

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

  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Kalven

perch predatory fish
typically ~24 cm · can reach 26 cm
Perch moves carefully in the clear water — small mouthfuls, many of them.
ruffe perch family
typically ~11 cm · can reach 11 cm
Ruffe lives down in the cool — the deep is its home ground all year.
burbot bottom fish
typically ~35 cm · can reach 35 cm
Burbot holds the bottom even in clear water — shade and depth are its cover.
roach coarse fish
typically ~11 cm · can reach 17 cm
Roach moves carefully in the clear water — small mouthfuls, many of them.
nors fish
typically ~11 cm · can reach 11 cm
Nors cruises the open water — the depth it picks follows the light through the day.

Fishing Kalven

perch and burbot sit at the top of the food chain in Kalven, carried by ruffe, roach and nors. 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 Kalven are alike.

General rules of thumb for this kind of water

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