The salmon louse larval black box: evaluating fecundity and enumerating planktonic stages with an aquaculture management perspective
(Doctoral thesis, 2022-06-17)Modern salmon aquaculture began in 1970 with the innovation of at-sea fish pens which precipitated a rapid growth in production. The expansion of the industry and increased number of farmed fish concentrated within the ... -
Dietary fatty acids and their ratio: impact on Atlantic salmon health, mineral status and intestinal lipid transport
(Doctoral thesis, 2022-06-30)The rapid growth of the aquaculture industry and the sharp decline of capture fisheries necessitates finding alternative sources for fish oil and fish meal in aquafeeds. However, the inclusion of VOs in aquafeed alters the ... -
Optimisation of dietary n-3 and n-6 fatty acids for a robust Atlantic salmon (Salmo salar)
(Doctoral thesis, 2022-06-28)An optimal diet for Atlantic salmon (Salmo salar) should promote a healthy fish that is robust to changes in its environmental conditions and can withstand the handling it will encounter under farming conditions, all while ... -
Estimating unreported catches in Norwegian fisheries
(Doctoral thesis, 2022-06-27)A discard ban for fish was introduced in Norway in 1987, which requires that all commercial catches must be landed and reported. In theory, this regulation creates a full record of total removals from all fisheries. However, ... -

Proof of Principle Efficacy and Safety Optimisation of Tenacibaculum Vaccine Prototypes Against Tenacibaculosis in Atlantic Salmon
(Master thesis, 2022-06-01)Mouthrot, caused by the bacterium Tenacibaculum maritimum, is a major health and welfare problem in newly sea-transferred Atlantic salmon smolts (Salmo salar) in BC, Canada, and have caused large economical losses over the ... -
Adaptive immune responses in Atlantic salmon after vaccination with bacterins of Pasteurella atlantica
(Master thesis, 2022-06-01)Utbrot av pasteurellose hjå atlanterhavslaks (Salmo salar L.) har sidan 2018 vore eit stort problem i oppdrettsnæringa, og framleis har inga kommersielt tilgjengeleg vaksine blitt utvikla. Vi veit lite om bakteriens ... -
Discards of cod (Gadus morhua) in the Norwegian coastal fisheries: improving past and future estimates
(Journal article; Peer reviewed, 2022)Discarding can be an unknown source of biases and uncertainties in stock assessments. Discarding patterns and quantities vary so a routine methodology for estimating discards is important to give a better picture of total ... -
The infection cycle of Marteilia pararefringens in blue mussels, Mytilus edulis, in a heliothermic marine oyster lagoon in Norway.
(Journal article; Peer reviewed, 2022)Agapollen is a traditional heliothermic marine oyster lagoon in western Norway, representing the northernmost site of any Marteilia sp. protists detected in Europe. The semi-closed lagoon is a unique site to study the life ... -
Mitogenomics of the suborder Cottoidei (Teleostei: Perciformes): Improved assemblies, mitogenome features, phylogeny, and ecological implications
(Journal article; Peer reviewed, 2022)We determined the mitogenome of Cyclopterus lumpus using a hybrid sequencing approach, and another four closely related species in the Liparidae based on available next-generation sequence data. We found that the mitogenome ... -
The teleost polymeric Ig receptor counterpart in ballan wrasse (Labrus bergylta) differs from pIgR in higher vertebrates
(Journal article; Peer reviewed, 2022)As mucosal barriers in fish are the main sites where pathogens are encountered, mucosal immunity is crucial to avoid infection in the aquatic environment. In teleost fish, immunoglobulins are present in gut, gill and skin ... -
Miljø-DNA påvisning av Pasteurella atlantica gv. salmonicida
(Master thesis, 2022-05-16)Pasteurellose forårsaket av Pasteurella atlantica gv. salmonicida hos atlantisk laks (Salmo salar L.) har de siste årene etablert seg som en bakteriesykdom som truer fiskevelferd og bærekraftig produksjon i den norske ... -
