Fishing Rogsjön
The species list of Rogsjön runs to 17. The predators — perch, pike and zander — hunt where the baitfish gather, and on a water this size every bay becomes its own fishery.
Every session at Rogsjön 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.
