English title: Sámi Indigenous knowledge and biological knowledge about the Deatnu River and salmon: How to strengthen the salmon stocks?

English abstract: The Deatnu River has been changing very rapidly, and there are no clear reasons for the steep decline of the wild Atlantic salmon stocks. Sámi knowledge holders raise various concerns regarding changes in salmon ecosystems, including increased predation, loss of spawning redds due to erosion, increased sports fishing, salmon aquaculture, and changes in food resources for salmon in the ocean. Fish biologists researching the Deatnu River region frequently investigate these concerns; however, they often lack precise data, making it challenging to definitively confirm or refute them. Their conclusion is that none of the apprehensions expressed by Sámi knowledge holders can singularly account for the observed negative trends in salmon stocks. While the biologists acknowledge the potential adverse effects of other elements, their conclusion attributes the primary cause of the decline to overfishing. Only in the past few years has the focus shifted to the changes in the ocean conditions and smolt survival. Sámi knowledge shows that aside from implementing fishing limitations, numerous other management measures could enhance the well-being of salmon throughout its different life stages. These include restricting the number of predators, restoring spawning redds, slowing down erosion, limiting open-pen salmon aquaculture, and improving the status of salmon food resources in the ocean by means of fishing restrictions.
