Escape- and diet-history among farmed Atlantic Salmon caught in Norwegian rivers and coast in the period 2011-2021
(Master thesis, 2022-06-01)Every year thousands of farmed Atlantic salmon (Salmo salar) escape from net pens in Norway, and introgression has been documented in two-thirds of the more than 200 wild populations investigated thus far. Farmed salmon ... -
Habitat variability and faunal zonation at the Ægir Ridge, a canyon-like structure in the deep Norwegian Sea
(Journal article; Peer reviewed, 2022)The Ægir Ridge System (ARS) is an ancient extinct spreading axis in the Nordic seas extending from the upper slope east of Iceland (∼550 m depth), as part of its Exclusive Economic Zone (EEZ), to a depth of ∼3,800 m in the ... -
Biodiversity and spatial ecology of arctic sponge grounds in the Nordic Seas
(Doctoral thesis, 2022-06-17)Sponge grounds are biogenic habitats formed by large structure-forming sponges in the deep-sea. They are biodiversity hotspots because they provide associated fauna a place of refuge, additional substratum, foraging areas, ... -
Smittemodellutvikling for Pasteurella atlantica gv. salmonicida og Pasteurella skyensis hos Atlantisk laks (Salmo salar)
(Master thesis, 2022-06-01)De siste årene har pasteurellose blitt et tiltakende problem i lakseoppdrett langs vestlandskysten av Norge. Sykdommen er i de fleste tilfellene forårsaket av bakterien med arbeidsnomenklaturen Pasteurella atlantica gv. ... -
Challenge model for Pasteurella atlantica genomovar salmonicida in Atlantic salmon (Salmo salar L.)
(Master thesis, 2022-06-01)Pasteurellose i Atlantisk laks (Salmo salar L.) har blitt et problem i Norge de siste årene. I fiskehelserapporten fra 2021 karakteriserte Veterinærinstituttet (VI) for første gang pasteurellose i Atlantisk laks som en ... -
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, ... -

(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 ... -
