• Can Energy Depletion of Wild Atlantic Salmon Kelts Negotiating Hydropower Facilities Lead to Reduced Survival? 

      Baktoft, Henrik; Gjelland, Karl Øystein; Szabo-Meszaros, Marcell; Silva, Ana T.; Riha, Milan; Økland, Finn; Alfredsen, Knut; Forseth, Torbjørn (Peer reviewed; Journal article, 2020)
      Repeat spawners constitute an important component of Atlantic salmon populations, but survival of post-spawning individuals (kelts) are often compromised by anthropogenic structures such as hydropower plants (HPPs). Potential ...
    • Modelling mitigation measures for smolt migration at dammed river sections 

      Szabo-Meszaros, Marcell; Forseth, Torbjørn; Baktoft, Henrik; Fjeldstad, Hans-Petter; Silva, Ana T.; Gjelland, Karl Øystein; Økland, Finn; Uglem, Ingebrigt; Alfredsen, Knut (Journal article; Peer reviewed, 2019)
      There is no generic solution to establish safe passage of downstream migrating fish passed hydropower facilities and mitigation measures are species‐ and site‐specific. Development of solutions is thus often based on “trial ...
    • Redefining the oceanic distribution of Atlantic salmon 

      Rikardsen, Audun H.; Righton, David; Strøm, John Fredrik; Thorstad, Eva Bonsak; Gargan, Patrick G.; Sheehan, Timothy F.; Økland, Finn; Chittenden, Cedar; Hedger, Richard David; Næsje, Tor; Renkawitz, Mark; Sturlaugsson, Johannes; Caballero, Pablo; Baktoft, Henrik; Davidsen, Jan Grimsrud; Halttunen, Elina; Wright, Serena; Finstad, Bengt; Aarestrup, Kim (Peer reviewed; Journal article, 2021)
      Determining the mechanisms driving range-wide reductions in Atlantic salmon marine survival is hindered by an insufcient understanding of their oceanic ecology and distribution. We attached 204 pop-up satellite archival ...
    • Three-dimensional migratory behaviour of European silver eels (Anguilla anguilla) approaching a hydropower plant 

      Kjærås, Halvor; Baktoft, Henrik; Silva, Ana T.; Gjelland, Karl Øystein; Økland, Finn; Forseth, Torbjørn; Szabo-Meszaros, Marcell; Calles, Olle (Peer reviewed; Journal article, 2022)
      Three-dimensional migratory behaviour of European silver eels (Anguilla anguilla) approaching a hydropower plant facilities to accomodate downstream eel migration. The results of this recommendation are poorly studied, and ...
    • Validation of a Swimming Direction Model for the Downstream Migration of Atlantic Salmon Smolts 

      Szabo-Meszaros, Marcell; Silva, Ana T.; Bærum, Kim Magnus; Baktoft, Henrik; Alfredsen, Knut; Hedger, Richard David; Økland, Finn; Gjelland, Karl Øystein; Fjeldstad, Hans-Petter; Calles, Olle; Forseth, Torbjørn (Peer reviewed; Journal article, 2021)
      Fish swimming performance is strongly influenced by flow hydrodynamics, but little is known about the relation between fine-scale fish movements and hydrodynamics based on in-situ investigations. In the presented study, ...
