    • Experimental hydraulics on fish-friendly trash-racks: an ecological approach 

      Szabo-Meszaros, Marcell; Navaratnam, Christy Ushanth; Aberle, Jochen; Silva, Ana T.; Forseth, Torbjørn; Calles, Olle; Fjeldstad, Hans-Petter; Alfredsen, Knut (Journal article; Peer reviewed, 2018)
      The obstruction of fish migratory routes by hydroelectric facilities is worldwide one of the major threats to freshwater fishes. During downstream migration, fish may be injured or killed on the trash-racks or in the ...

    • 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, ...
