Character of the water

Marsjön lies in central Sweden — a clear oligotrophic forest lake.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Large and deep (20 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Pike: keep at most one over 75 cm per day.

Species in Marsjön

perch predatory fish

typically ~22 cm · can reach 45 cm

Perch moves carefully in the clear water — small mouthfuls, many of them.

ål fish

typically ~55 cm · can reach 110 cm

Ål holds the bottom even in clear water — shade and depth are its cover.

elritsa fish

typically ~7 cm · can reach 12 cm

Here elritsa lives on the small stuff — and rewards those who fish small and fine.

pike predatory fish

typically ~62 cm · can reach 120 cm

In the clear water pike picks its moments — wary, but relentless once committed.

burbot bottom fish

typically ~45 cm · can reach 90 cm

Burbot holds the bottom even in clear water — shade and depth are its cover.

salmon fish

typically ~65 cm · can reach 130 cm

Salmon is a sight-hunter here — the clear water means long follows before the take.

roach coarse fish

typically ~18 cm · can reach 32 cm

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

Arctic char salmonids

typically ~35 cm · can reach 70 cm

In the clear water Arctic char picks its moments — wary, but relentless once committed.

whitefish whitefish

typically ~30 cm · can reach 55 cm

Whitefish holds in the open water column where light and temperature set the day.

vendace whitefish

typically ~16 cm · can reach 28 cm

Vendace cruises the open water — the depth it picks follows the light through the day.

Fishing Marsjön

Marsjön holds 10 species, with perch, pike and burbot at the top of the chain and ål, elritsa and roach schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Every session at Marsjön 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

In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
