Deep-diving of Atlantic salmon ($\textit{Salmo salar}$) during their marine feeding migrations
Data from seven data storage tags recovered from Atlantic salmon marked as smolts were analyzed for depth movements and patterns of deep diving during the marine migration. The salmon mostly stayed at the surface and showed diurnal activity especially from autumn until spring. During the first month...

Data from seven data storage tags recovered from Atlantic salmon marked as smolts were analyzed for depth movements and patterns of deep diving during the marine migration.

The salmon took short deep dives (> 100 m), that were rare or absent during the first summer at sea but increased in frequency and duration especially in late winter.

The initiation of the dives was more common in evenings and at night, suggesting nocturnal diving. We hypothesized that deep diving is related to feeding of salmon as mesopelagic fish can be important food for salmon during winter. : 12 pages, 4 figures |
