Character of the water

Mörtsjön lies in central Sweden — a 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.

Moderately deep (4 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

  • 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.

Species in Mörtsjön

typically ~22 cm · can reach 45 cm

typically ~55 cm · can reach 110 cm
Ål holds the bottom even in clear water — shade and depth are its cover.

Roach moves carefully in the clear water — small mouthfuls, many of them.
trout salmonids

In the clear water trout picks its moments — wary, but relentless once committed.
regnbåge fish
typically ~35 cm · can reach 70 cm
Regnbåge is a sight-hunter here — the clear water means long follows before the take.
ruda fish
typically ~18 cm · can reach 42 cm
Ruda lives down in the cool — the deep is its home ground all year.

Fishing Mörtsjön

The species list of Mörtsjön runs to 6. The predators — perch and trout — 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.
