      Havforskningsinstituttet begynte med en systematisk registrering av innrapporterte funn av strandet krill i 2014. Antall tilfeller var få fra 2014 til 2017, men økte kraftig i 2018 og har siden holdt seg på dette nivået. ...
    • The impact of anti-sea lice pesticides, azamethiphos and deltamethrin, on European lobster (Homarus gammarus) larvae in the Norwegian marine environment 

      Parsons, Aoife Elizabeth; Escobar, Rosa; Sævik, Pål Næverlid; Samuelsen, Ole Bent; Agnalt, Ann-Lisbeth (Peer reviewed; Journal article, 2020)
      Anti-sea lice pesticides, used in the salmonid aquaculture industry, are a growing environmental concern due to their potential to adversely affect non-target crustaceans. Azamethiphos and deltamethrin are two bath treatment ...
    • The lunar compass of European glass eels (Anguilla anguilla) increases the probability that they recruit to North Sea coasts 

      Cresci, Alessandro; Sandvik, Anne Dagrun; Sævik, Pål Næverlid; Ådlandsvik, Bjørn; Olascoaga, Maria Josefina; Miron, Philippe; Durif, Caroline; Skiftesvik, Anne Berit; Browman, Howard; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2020)
      The European eel hatches in the Sargasso Sea and migrates across the Atlantic Ocean toward Europe. At the continental shelf, larvae metamorphose into glass eels and then recruit to coastal habitats and estuaries. Among ...
    • Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids 

      Skern-Mauritzen, Rasmus; Sissener, Nini; Sandvik, Anne Dagrun; Meier, Sonnich; Sævik, Pål Næverlid; Skogen, Morten D.; Vågseth, Tone; Dalvin, Sussie; Skern-Mauritzen, Mette; Bui, Samantha (Peer reviewed; Journal article, 2020)
      The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ...
    • Prediction of salmon lice infestation pressure in a Norwegian fjord 

      Sandvik, Anne Dagrun; Johnsen, Ingrid Askeland; Myksvoll, Mari Skuggedal; Sævik, Pål Næverlid; Skogen, Morten D. (Peer reviewed; Journal article, 2020)
      A further growth in the Norwegian aquaculture industry might potentially be hampered by the conclusion that it is not environmentally sustainable. As direct measurements of the lice induced mortality on wild salmonids are ...
    • Salmon lice-induced mortality of Atlantic salmon during post-smolt migration in Norway 

      Johnsen, Ingrid Askeland; Harvey, Alison C.; Sævik, Pål Næverlid; Sandvik, Anne Dagrun; Ugedal, Ola; Ådlandsvik, Bjørn; Wennevik, Vidar; Glover, Kevin; Karlsen, Ørjan (Peer reviewed; Journal article, 2020)
    • Simulating particle organic matter dispersal beneath Atlantic salmon fish farms using different resuspension approaches 

      Carvajalino-Fernandez, Marcos Antonio; Sævik, Pål Næverlid; Johnsen, Ingrid Askeland; Albretsen, Jon; Keeley, Nigel B. (Peer reviewed; Journal article, 2020)
      An accurate representation of the particle organic matter (POM) footprint is necessary in order to effectively predict impacts upon benthic communities and the risk of excessive organic enrichment beneath aquaculture ...
    • Utvandring av virtuell postsmolt 2018/2019 

      Johnsen, Ingrid Askeland; Sævik, Pål Næverlid; Ådlandsvik, Bjørn (Rapport fra havforskningen;2019 - 55, Research report, 2019)
      For å estimere belastninga vill atlantisk laks (Salmo salar) opplever grunna påslag av lakselus (Lepeophtheirus salmonis) frå oppdrettsanlegg i løpet av utvandringa som postsmolt, er det køyrt ein modell som fører virtuelle ...
