Character of the water

Mörtträsket lies in the cold north — a northern 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 lies half-remote, a fair way from the nearest road, tucked into woodland.

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

Permits & rules

Fishing permit required — Mörtträsket 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 Mörtträsket

perch predatory fish

In the murky light, pike shadows the baitfish and hits in short rushes.
burbot bottom fish
typically ~45 cm · can reach 90 cm
Burbot works the bottom in the dark — smell and feel come before everything else.
roach coarse fish

Roach grazes the rich water in schools — where there's one, there are more.
vendace whitefish
typically ~16 cm · can reach 28 cm

Fishing Mörtträsket

The species list of Mörtträsket runs to 5. The predators — perch, pike and burbot — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Mörtträsket is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

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.
  • Acidified water yields few, hardy species.
