Character of the water

Mörtsjön lies in the south — a southern acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. 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.

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

Permits & rules

Fishing permit required — Mörtsjön 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.

Fishing Mörtsjön

The species list of Mörtsjön runs to 6. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Mörtsjön 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • Acidified water yields few, hardy species.
