Abstract: The management and conservation of salmonids populations in Norway have become increasingly critical in the face of growing anthropogenic pressures and climate change impacts. Norway, as a major hydropower producer, often has its rivers fragmented by hydropower plants (HPP), which significantly affect aquatic biodiversity. Migratory species such as Atlantic salmon are highly impacted by the presence of HPP. Due to their ecological, economical, and social importance this species is often served as lead species for conservation efforts. In Norway several studies have investigated the behaviour of Atlantic salmon in the presence of HPP. This knowledge is crucial for developing solutions that prioritize the safe and efficient migration of this species ultimately increasing survival rates and safeguarding the ecological health of its populations. While solutions for upstream migration have been well-researched, little information exist on downstream migration of Atlantic salmon. The Safepass, FishFence, FishPath, and Kelt2Sea, herein presented, are among the international initiatives in Norway addressing this issue. These projects were affiliated with or received funding from the HydroCen center, a Norwegian centre dedicated to innovative research on environmentally friendly energy. These efforts are integral to the sustainable management of salmonids in Norway, aligning with the ongoing development of sustainable hydropower sources.
