Characterization of three salmon louse (Lepeophtheirus salmonis) genes with fibronectin II domains expressed by tegumental type 1 glands
Harasimczuk, Ewa; Øvergård, Aina-Cathrine; Grotmol, Sindre; Nilsen, Frank; Dalvin, Sussie (Peer reviewed; Journal article, 2018-01)The salmon louse, Lepeophtheirus salmonis (Copepoda: Caligidae), is currently the most significant pathogen affecting the salmon farming industry in the Northern Hemisphere. Exocrine glands of blood-feeding parasites are ... -
Cloned and outbred Atlantic salmon display equal parasite dispersion when infected with the salmon louse
Glover, Kevin; Hansen, Tom Johnny; Besnier, Francois; Solberg, Monica Favnebøe; Fjelldal, Per Gunnar; Sørvik, Anne Grete Eide; Dalvin, Sussie; Nilsen, Frank (Peer reviewed; Journal article, 2017-11)The salmon louse is an ectoparasitic copepod that infects salmonids in the marine environment. This parasite causes a major economic and biological challenge to the Atlantic salmon farming industry, and efforts to increase ... -
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 ... -
The ecdysone receptor (EcR) is a major regulator of tissue development and growth in the marine salmonid ectoparasite, Lepeophtheirus salmonis (Copepoda, Caligidae)
Sandlund, Liv; Nilsen, Frank; Male, Rune; Dalvin, Sussie (Peer reviewed; Journal article, 2016-08)The function of the ecdysone receptor (EcR) during development and molting has been thoroughly investigated in some arthropods such as insects but rarely in crustacean copepods such as the salmon louse Lepeophtheirus ... -
The effect of temperature on ability of Lepeophtheirus salmonis to infect and persist on Atlantic salmon
Dalvin, Sussie; Hamre, Lars Are; Skern-Mauritzen, Rasmus; Vågseth, Tone; Stien, Lars Helge; Oppedal, Frode; Bui, Samantha (Journal article; Peer reviewed, 2020)The salmon louse (Lepeophtheirus salmonis) is an ecologically and economically important parasite of salmonid fish. Temperature is a strong influencer of biological processes in salmon lice, with development rate increased ... -
Effects of chitin synthesis inhibitor treatment on Lepeophtheirus salmonis (Copepoda, Caligidae) larvae
Hardardottir, Hulda; Male, Rune; Nilsen, Frank; Dalvin, Sussie (Peer reviewed; Journal article, 2019-09-23)The salmon louse (Lepeophtheirus salmonis) is an ectoparasite infecting Atlantic salmon (Salmo salar), which causes substantial problems to the salmon aquaculture and threatens wild salmon. Chitin synthesis inhibitors ... -
Identification and characterisation of the ecdysone biosynthetic genes neverland, disembodied and shade in the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae)
Sandlund, Liv; Kongshaug, Heidi; Horsberg, Tor Einar; Male, Rune; Nilsen, Frank; Dalvin, Sussie (Peer reviewed; Journal article, 2018-02-05)The salmon louse is a marine ectoparasitic copepod on salmonid fishes. Its lifecycle consists of eight developmental stages, each separated by a molt. In crustaceans and insects, molting and reproduction is controlled by ... -
Microsomal triglyceride transfer protein in the ectoparasitic crustacean salmon louse (Lepeophtheirus salmonis)
Khan, Muhammad Tanveer; Dalvin, Sussie; Nilsen, Frank; Male, Rune (Peer reviewed; Journal article, 2017-08)The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish. Salmon lice produce high numbers of offspring, necessitating ... -
Molecular characterization of the lipophorin receptor in the crustacean ectoparasite Lepeophtheirus salmonis
Khan, Muhammad Tanveer; Dalvin, Sussie; Waheed, Qaiser; Nilsen, Frank; Male, Rune (Peer reviewed; Journal article, 2018-04-12)The Salmon louse (Lepeophtheirus salmonis) is a marine ectoparasite of salmonid fish in the Northern Hemisphere and considered as a major challenge in aquaculture and a threat to wild populations of salmonids. Adult female ... -
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 ... -
Rainbow trout Oncorhynchus mykiss skin responses to salmon louse Lepeophtheirus salmonis: From copepodid to adult stage
Dalvin, Sussie; VG Jørgensen, Louise; Kania, Per W.; Grotmol, Sindre; Buchmann, Kurt; Øvergård, Aina-Cathrine (Journal article; Peer reviewed, 2020)The marine crustacean Lepeophtheirus salmonis (salmon louse) is a common ectoparasite of wild and farmed salmonids. The parasite has a complex ontogeny comprising eight instars. The planktonic copepodid stage settles on ...
