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) -
Salmon louse infestation levels on sea trout can be predicted from a hydrodynamic lice dispersal model
Bøhn, Thomas; Nilsen, Rune; Gjelland, Karl Øystein; Biuw, Martin; Sandvik, Anne Dagrun; Primicerio, Raul; Karlsen, Ørjan; Serra Llinares, Rosa Maria (Peer reviewed; Journal article, 2021)The abundance of the parasitic salmon louse has increased with the growth in aquaculture of salmonids in open net pens. This represents a threat to wild salmonid populations as well as a key limiting factor for salmon ... -
Sampling planktonic salmon lice in Norwegian fjords
Skardhamar, Jofrid; Fagerli, Margrethe Nilsen; Reigstad, Marit; Sandvik, Anne Dagrun; Bjørn, Pål Arne (Journal article; Peer reviewed, 2019)Risk of mortality of wild salmon caused by salmon lice is used as an index for managing aquaculture production in Norway and is based on monitoring of lice attached to wild salmonids and modelled concentrations of lice ... -
Smittepress fra lakselus på vill laksefisk – estimert fra luselarvefelt med stor variabilitet
Sandvik, Anne Dagrun; Asplin, Lars; Bjørn, Pål Arne; Johnsen, Ingrid Askeland; Skardhamar, Jofrid; Myksvoll, Mari Skuggedal; Ådlandsvik, Bjørn; Skogen, Morten D. (Rapport fra havforskningen;Nr. 13 - 2017, Research report, 2017) -
A step towards high resolution modeling of the central Faroe shelf circulation by FarCoast800
Erenbjerg, Sissal V.; Albretsen, Jon; Simonsen, Knud; Sandvik, Anne Dagrun; Kaas, Eigil (Peer reviewed; Journal article, 2020)This paper describes the FarCoast800 model setup for the Faroe shelf and the validation towards observations. We found that the circulation was in accordance with observations on the shelf and the upper 500m of the water ... -
Strøm i fjorder - strømkatalog og smittespredning
Asplin, Lars; Sandvik, Anne Dagrun; Albretsen, Jon (Havforskningsnytt;Nr. 9 - 2011, Working paper, 2011)Strøm, saltholdighet og temperatur er grunnleggende parametre som har en direkte innvirkning på økosystemene i fjordene. Ved hjelp av et nytt modellsystem som er under utvikling, vil vi både kunne beskrive hvordan strømmen ... -
Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities
Bøhn, Thomas; Gjelland, Karl Øystein; Serra Llinares, Rosa Maria; Finstad, Bengt; Primicerio, Raul; Nilsen, Rune; Karlsen, Ørjan; Sandvik, Anne Dagrun; Skilbrei, Ove Tommy; Elvik, Kristine Marit Schrøder; Skaala, Øystein; Bjørn, Pål Arne (Peer reviewed; Journal article, 2020)Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations. In this study, n = 29,817 tagged Atlantic salmon were studied ... -
Toward a model-based prediction system for salmon lice infestation pressure
Sandvik, Anne Dagrun; Bjørn, Pål Arne; Ådlandsvik, Bjørn; Asplin, Lars; Skardhamar, Jofrid; Johnsen, Ingrid Askeland; Myksvoll, Mari Skuggedal; Skogen, Morten D. (Journal article; Peer reviewed, 2016-09-08)High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary. The national Norwegian salmon ... -
Vertical salmon lice behaviour as a response to environmental conditions and its influence on regional dispersion in a fjord system
Johnsen, Ingrid A.; Fiksen, Øyvind; Sandvik, Anne Dagrun; Asplin, Lars (Journal article; Peer reviewed, 2014-06-04)The salmon louse Lepeophtheirus salmonis is a major parasite of salmon, and is able to travel between farms during its pelagic phases. We investigated the spatial dispersion of L. salmonis planktonic stages in the ...
