Characterization of a novel RXR receptor in the salmon louse (Lepeophtheirus salmonis, Copepoda) regulating growth and female reproduction
Eichner, Christiane; Dalvin, Sussie Trine; Skern-Mauritzen, Rasmus; Malde, Ketil; Kongshaug, Heidi; Nilsen, Frank (Peer reviewed; Journal article, 2015-02-14)Background: Nuclear receptors have crucial roles in all metazoan animals as regulators of gene transcription. A wide range of studies have elucidated molecular and biological significance of nuclear receptors but there are ... -
Coincident mass occurrence of gelatinous zooplankton in Northern Norway
Knutsen, Tor; Hosia, Aino; Falkenhaug, Tone; Skern-Mauritzen, Rasmus; Wiebe, Peter H.; Larsen, Roger B.; Aglen, Asgeir; Berg, Erik (Peer reviewed; Journal article, 2018-05-23)In autumn 2015, several sources reported observations of large amounts of gelatinous material in a large north Norwegian fjord system, either caught when trawling for other organisms or fouling fishing gear. The responsible ... -
Development of the salmon louse Lepeophtheirus salmonis parasitic stages in temperatures ranging from 3 to 24°C
Hamre, Lars Are; Bui, Samantha; Oppedal, Frode; Skern-Mauritzen, Rasmus; Dalvin, Sussie (Peer reviewed; Journal article, 2019-09-05)The development rate of the salmon louse Lepeophtheirus salmonis is greatly influenced by seawater temperature. This study describes how the growth rate of L. salmonis changes with temperature and identifies the extreme ... -
Human-induced evolution caught in action: SNP-array reveals rapid amphi-atlantic spread of pesticide resistance in the salmon ecotoparasite Lepeophtheirus salmonis
Besnier, Francois; Kent, Matthew; Skern-Mauritzen, Rasmus; Lien, Sigbjørn; Malde, Ketil; Edvardsen, Rolf; Taylor, Simon; Ljungfeldt, Lina; Nilsen, Frank; Glover, Kevin (Peer reviewed; Journal article, 2014-10-26)Background: The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ... -
Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo
Skern-Mauritzen, Rasmus; Torrissen, Ole; Glover, Kevin (Peer reviewed; Journal article, 2014-03-14)Background: The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have ... -

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 (Journal article; Peer reviewed, 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 ... -
The salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae) life cycle has only two chalimus stages
Hamre, Lars Are; Eichner, Christiane; Caipang, Christopher; Dalvin, Sussie Trine; Bron, James E.; Nilsen, Frank; Boxshall, Geoffrey; Skern-Mauritzen, Rasmus (Peer reviewed; Journal article, 2013-09-12)Each year the salmon louse (Lepeophtheirus salmonis Krøyer, 1838) causes multi-million dollar commercial losses to the salmon farming industry world-wide, and strict lice control regimes have been put in place to reduce ... -
