    • Acoustic telemetry predation sensors reveal the tribulations of Atlantic salmon (Salmo salar) smolts migrating through lakes 

      Hanssen, Erlend Mjelde; Vollset, Knut Wiik; Salvanes, Anne Gro Vea; Barlaup, Bjørn; Whoriskey, Kim; Isaksen, Trond Einar; Normann, Eirik Straume; Hulbak, Magnus Andre; Lennox, Robert (Journal article; Peer reviewed, 2021)
      Smolt migration through lakes is hazardous, as the predation pressure can be extreme and the hydrology a great contrast to that of a riverine area. However, the mechanisms yielding these challenges have been scarcely ...

    • Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers 

      Sortland, Lene; Lennox, Robert; Velle, Gaute; Vollset, Knut; Kambestad, Marius (Journal article; Peer reviewed, 2023)
      1. The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human–predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate ...

    • Positioning aquatic animals with acoustic transmitters 

      Lennox, Robert; Aarestrup, Kim; Alós, Josep; Arlinghaus, Robert; Aspillaga, Eneko; Bertram, Michael G.; Birnie-Gauvin, Kim; Brodin, Tomas; Cooke, Steven J.; Dahlmo, Lotte Svengård; Dhellemmes, Félicie; Gjelland, Karl Øystein; Hellström, Gustav; Hershey, Henry; Holbrook, Christopher; Klefoth, Thomas; Lowerre-Barbieri, Susan; Monk, Christopher T.; Nilsen, Cecilie Iden; Pauwels, Ine; Pickholtz, Renanel; Prchalová, Marie; Reubens, Jan; Říha, Milan; Villegas-Ríos, David; Vollset, Knut; Westrelin, Samuel; Baktoft, Henrik (Journal article; Peer reviewed, 2023)
      Geolocating aquatic animals with acoustic tags has been ongoing for decades, relying on the detection of acoustic signals at multiple receivers with known positions to calculate a 2D or 3D position, and ultimately recreate ...

    • Validating timing of salmon smolt runs obtained by telemetry studies 

      Hulbak, Magnus Andre; Hanssen, Erlend Mjelde; Lennox, Robert; Salvanes, Anne Gro Vea; Barlaup, Bjørn Torgeir; Gharbi, Naouel; Nilsen, Tom Ole; Vollset, Knut (Journal article; Peer reviewed, 2021)
      Telemetry tags are increasingly used in management to monitor the migration timing of Atlantic salmon smolts (Salmo salar L.). It has been postulated that (1) effects from tagging and handling may alter migration behaviour, ...
