Fishing license rules
Everyone who fishes is obliged to know the applicable rules before starting fishing.
- In order to have better fishing in the future, we have decided to introduce strict catch & release for all fishing licenses for 2026. This means that no fish may be kept regardless of the species of fish or type of fishing license.
- All fish are released carefully. (Keepnet may be used during fishing)
- Fishing may be conducted between 06:00 - 22:00, January 1-September 14. Fishing license must be carried with all fishing and presented together with valid identification upon request.
- Fishing with ONE ROD, lure, fly or angling with ONE hook (lures with several factory-mounted hooks allowed, e.g. a wobbler with more than one hook).
- Please note! Fishing methods other than those specified as permitted above are completely prohibited, e.g. net fishing, longline fishing, jerk fishing, sinking nets, cast nets (e.g. for bait fish), trolling, pike shears, otter boards, angle fishing, and the use of a hook is completely prohibited throughout the year.
- It is not permitted to use fish as bait, either dead or alive.
- All fishing from 15 September to 31 December is prohibited. Applies to the entire Trosaån FVO (see map below). This protection has been established by Trosaån FVO, the Swedish Board of Fisheries (FIFS 2004:36) and the County Administrative Board of Södermanland County.
- Fishing is prohibited from the dam in Vagnhärad to the footbridge under the railway and in the rapids at Trosa Kvarn. This applies all year round.
- Fishing from boats and bridges over Trosaån is prohibited.
- Make sure that the place you fished is as clean when you leave it as when you started your fishing.
The Trosa River is monitored by a number of trained supervisors, who conduct inspections of the fishing almost every day. These have powers that are part of the supervision work. Violations of the fishing rules are punished through inspection and action. The police and coast guard are called in if necessary. Confiscation of equipment and fishing licenses may occur.
All income from fishing licenses goes to fish conservation work, e.g. releases, training, etc. FVO, Trosa Amateur Fishing Club and Trosa Municipality are actively working to improve conditions for all fish, other animals and plants through the ambition to restore the Trosa River and create protected areas for spawning fish. In order to maintain the existing sea trout population, around 2-3,000 sea trout are released into the river annually.
