The surroundings

Shallow throughout (max 2 m), with reeds and vegetation over large areas — water that warms fast in spring.

- Pike: keep at most one over 75 cm per day.
- Handheld tackle only. Respect the protected zones at the inlets and outlets.

Bream holds the bottom even in clear water — shade and depth are its cover.
pike predatory fish

Fishing Rostockasjön
Rostockasjön holds 6 species, with perch and pike at the top of the chain and björkna, bream and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.
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 Rostockasjön are alike.
