Character of the water

Halvtron lies in central Sweden — a clear oligotrophic deep 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 (32 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Species in Halvtron

perch predatory fish

typically ~22 cm · can reach 45 cm

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

pike predatory fish

typically ~62 cm · can reach 120 cm

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

roach coarse fish

typically ~18 cm · can reach 32 cm

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

burbot bottom fish

typically ~45 cm · can reach 90 cm

Burbot lives down in the cool — the deep is its home ground all year.

Fishing Halvtron

Halvtron holds 4 species, with perch, pike and burbot at the top of the chain and roach schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Halvtron are alike.

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.
