Fishing Öster-Terrsjön
Öster-Terrsjön holds 10 species, with perch, pike and grayling at the top of the chain and ål, elritsa 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 Öster-Terrsjön are alike.
General rules of thumb for this kind of water
