Character of the water

Mörttjärnen lies in the cold north — a northern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 7 m and splits the lake into two worlds. Acidification has thinned life down to the hardiest few.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

A small but surprisingly deep pocket (17 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Mörttjärnen FVOF. Day permit ~60 kr · annual permit ~300 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

perch predatory fish
typically ~22 cm · can reach 45 cm

Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.

Fishing Mörttjärnen

The species list of Mörttjärnen runs to 2. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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 Mörttjärnen 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.
