Decline of Atlantic Salmon in Norway

This chapter explores the alarming decline of Atlantic salmon populations in Norway, driven by factors such as the ban on river angling due to low fish numbers and the detrimental impact of the fish farming industry. Researchers at the Etna River Research Station gather data highlighting critical issues like fish mortality, reproductive challenges, and genetic risks from farmed fish. The chapter also discusses environmental shifts, including climate change, pollution, and invasive species, that further complicate the survival of both wild and farmed salmon.
