Development of a vaccine against salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2018-06-26)Aquaculture is a growing industry whilst facing a major problem, the ectoparasite Lepeophtheirus salmonis. Parasite control in 2015 was estimated to cost 5 billion NOK. The challenges with the parasite are complex, and the ... -
An investigation into the parasitic barnacle, Anelasma squalicola; prevalence, infection behaviour and effects on its host, Etmopterus spinax, in Lusterfjord, Norway.
(Master thesis, 2016-06-27)Anelasma squalicola is a recently evolved parasite. Very little is known of its biology due to its normally low prevalence in deep sea lantern sharks (family: Etmopteridae), in which it is found embedded in the skin. A ... -
A morphological study of the parasitic barnacle, Anelasma squalicola (Lovén, 1844)
(Master thesis, 2016-06-30)Objectives and Summary The pedunculate barnacle, Anelasma squalicola, is found parasitizing various squaloid sharks of the family Etmopteridae. Its peduncle has been modified to bury in the flesh of its host, and has ... -
Mucosal responses in post-smolt Atlantic salmon (S. salar) following salmon lice (L. salmonis) infections
(Master thesis, 2018-05-04)The aquaculture sector is becoming increasingly important both for food production and economic reasons. The main problem today in Norwegian aquaculture is the copepod ectoparasite Leopeophtheirus salmonis which limits the ... -
Optimal response to lousy circumstances: The impact of salmon lice (Lepeophtheirus salmonis) on depth preference of sea trout (Salmo trutta)
(Master thesis, 2018-06-12)Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. Still, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 wild caught sea trout, ... -
Study of Ecdysone receptor and Ultraspiracle in the salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2015-05-31)The salmon louse (Lepeophtheirus salmonis) is a parasite living on mucus, skin and blood of salmonids fishes. L. salmonis causes lesions and infections on fish fins and skins and such physical damages often lead to other ... -
Tissue tropism and non-lethal detection of Nucleospora cyclopteri (Microsporidia) in lumpfish (Cyclopterus lumpus L.)
(Master thesis, 2018-06-13)In the present study, wild-caught mature lumpfish (Cyclopterus lumpus) from a brood fish fishery in Norway were examined for the microsporidian parasite Nucleospora cyclopteri. This was done in order to reveal the tissue ...
