Salmon lice infection on wild salmonids in marine protected areas: an evaluation of the Norwegian ‘National Salmon Fjords
Serra-Llinares, Rosa Maria; Bjørn, Pål Arne; Finstad, Bengt; Nilsen, Rune; Harbitz, Alf; Berg, Marius; Asplin, Lars (Journal article; Peer reviewed, 2014-02-05)In Norway, 29 fjords and 52 rivers have been designated for protection in order to prevent the infection of important populations of wild salmonids with salmon lice of farm origin. We evaluated the effect of this protection ... -
Sea trout adapt their migratory behaviour in response to high salmon lice concentrations
Halttunen, Elina; Gjelland, Karl Øystein; Hamel, Sandra; Serra-Llinares, Rosa Maria; Nilsen, Rune; Arechavala-Lopez, Pablo; Skardhamar, Jofrid; Johnsen, Ingrid Askeland; Asplin, Lars; Karlsen, Ørjan; Bjørn, Pål Arne; Finstad, Bengt (Peer reviewed; Journal article, 2017)Sea trout face growth – mortality trade-offs when entering the sea to feed. Salmon lice epizootics resulting from aquaculture have shifted these trade-offs, as salmon lice might both increase mortality and reduce growth ... -
Small-scale genetic structure in a marine population in relation to water circulation and egg characteristics
Ciannelli, Lorenzo; Knutsen, Halvor; Olsen, Esben Moland; Espeland, Sigurd Heiberg; Asplin, Lars; Jelmert, Anders; Knutsen, Jan Atle; Stenseth, Nils Christian (Journal article; Peer reviewed, 2010-10)Until the last decade it was assumed that most marine species have pronounced gene flow over vast areas, largely because of their potential for dispersal during early life stages. However, recent genetic, modeling, and ... -
Summertime M2 Internal Tides in the Northern Yellow Sea
Lin, Fan; Asplin, Lars; Wei, Hao (Peer reviewed; Journal article, 2021)The summertime M2 internal tide in the northern Yellow Sea is investigated with moored current meter observations and numerical current model results. The hydrodynamic model, which is implemented from the Regional Ocean ... -
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 ...
