Atlantic salmon in a rapidly changing environment - facing the challenges of reduced marine survival and climate change

The global scale of climate change, altered ocean ecosystems and reduced sea survival make these threats to Atlantic salmon difficult - but not impossible - to address. We review impacts and suggest management options in a new article.
