Character of the water
Derasjö lies in the south — a southern humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Shallow throughout (max 4 m), with reeds and vegetation over large areas — water that warms fast in spring.

Fishing permit required — Derasjö FVOF. Day permit ~60 kr · annual permit ~300 kr.
- Pike: keep at most one over 75 cm per day.
- Handheld tackle only. Respect the protected zones at the inlets and outlets.

sarv fish

Fishing Derasjö
The species list of Derasjö runs to 5. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.
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 Derasjö are alike.
General rules of thumb for this kind of water
- Brown, humic water dampens the light — fishing can be good even in the middle of the day.
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
