Character of the water
Gransjön lies in the south — a southern nutrient-rich lowland lake.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
A small but surprisingly deep pocket (15 m) with steep drops straight down from shore — the bottom falls away fast.
Permits & rules
Fishing permit required — Gransjön 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 Gransjön
perch predatory fish
typically ~16 cm · can reach 48 cm
Perch grazes the rich water in schools — where there's one, there are more.
bream coarse fish
typically ~38 cm · can reach 65 cm
Down on the bottom bream sifts the soft ground — patience beats speed here.
pike predatory fish
typically ~67 cm · can reach 67 cm
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
typically ~20 cm · can reach 30 cm
Roach grazes the rich water in schools — where there's one, there are more.
regnbåge fish
typically ~35 cm · can reach 70 cm
Regnbåge hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
Fishing Gransjön
Gransjön holds 6 species, with perch, pike and burbot at the top of the chain and bream, roach and regnbåge schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.
Whoever fishes Gransjön regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.
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.
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
