The Norwegian Veterinary Institute begins building a trap at Seida to sort out invasive pink salmon migrating up the Tana River.

After a slow start, 66 000 invasive pink salmon have been caught in Troms and Finnmark rivers so far, but volunteers and authorities warn a larger run may still be on its way.

Fisherman Edgar Olsen hauled in over 2,000 invasive pink salmon in one seine cast during trial fishing at the Vesterelva estuary in Nesseby, distributing about half to locals and sending the rest to Lerøy.

Large numbers of post‑spawning pink salmon are rotting along the Alta River in Finnmark, causing strong odors and anger among anglers. Critics say the river lacked an effective trap in 2025, while managers and authorities cite technical challenges and are using netting and clean‑ups as interim measures.

In Kvænangen river traps caught a 30:1 ratio of invasive pink salmon to wild Atlantic salmon, requiring up to three emptyings per day.
