Blue mussel (Mytilus edulis) silage, a possible low trophic marine protein source for Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2024)Blue mussel (Mytilus edulis) could be a promising marine protein source in fish feeds and is of great interest since it can be cultivated along the Norwegian coastline. However, the use of blue mussels in feeds is dependent ... -
Exploring the use of blue mussel silage and fermented sugar kelp as low trophic marine resources in the Atlantic salmon (Salmo salar L.) diet
(Doctoral thesis, 2024-09-25)Havbrukssektoren er i rask vekst og er forventa å bidra med meir mat frå havet til den globale matforsyninga. Berekraftig vekst i fiskeoppdrett er avhengig av å finne nye fôringrediensar som har potensiale for oppskalering ... -
Heterologous production, purification and substrate usage of a variant of the marine globupain protease

Effects of different photoperiods regimes on growth and osmoregulation in Atlantic salmon
(Master thesis, 2024-03-20) -
Composition of Gelatinous Zooplankton Communities in Korsfjord and Fanafjord: seasonal dynamics and change over 20 years
(Master thesis, 2024-02-22)Marine zooplankton are vital components of pelagic ecosystems. Gelatinous zooplankton refers to a polyphyletic group of soft-bodied gelatinous organisms including the pelagic cnidarians and ctenophores. Despite being an ... -
Selenoprotein determination in tissues of Atlantic salmon (Salmo salar)
(Master thesis, 2024-06-03)Selen er et viktig mikronæringsstoff for både mennesker og dyr, inkludert fisk som Atlantisk laks (Salmo salar), og har en viktig rolle innen antioksidantforsvar og proteinsyntese. Hos fisk så er kostholdet hovedkilden for ... -
Annelid functional genomics reveal the origins of bilaterian life cycles
(Journal article; Peer reviewed, 2023)Indirect development with an intermediate larva exists in all major animal lineages1, which makes larvae central to most scenarios of animal evolution2,3,4,5,6,7,8,9,10,11. Yet how larvae evolved remains disputed. Here we ... -
Light and temperature controls of aquatic plant photosynthesis downstream of a hydropower plant and the effect of plant removal
(Journal article; Peer reviewed, 2023)Many rivers worldwide are regulated, and the altered hydrology can lead to mass development of aquatic plants. Plant invasions are often seen as a nuisance for human activities leading to costly remedial actions with ... -
Holocene changes in the position of the Southern Hemisphere Westerlies recorded by long-distance transport of pollen to the Kerguelen Islands
(Journal article; Peer reviewed, 2024)The Southern Hemisphere Westerlies (SHW) are a vital part of the Southern Hemisphere's coupled ocean-atmosphere system and play an important role in the global climate system. The SHW affect the upwelling of carbon-rich ... -
Winds of change : A multi-proxy approach to constrain Holocene climate and wind dynamics in the sub-Antarctic
(Doctoral thesis, 2024-09-05)Kunnskap om tidligere tiders naturlige klimavariasjoner er hovednøkkelen for å forstå vår nåværende klimatilstand. Det er også viktig for å kunne vurdere omfanget og retningen til fremtidige klimaendringer som forventes ... -
Metabolic pathways and physiological functions of organic and inorganic trace minerals in Atlantic Salmon
(Doctoral thesis, 2024-09-05)Mineralernæring spiller en nøkkelrolle for helse, velferd og prestasjonen til oppdrettet Atlantisk laks (Salmo salar), da den påvirker ulike fysiologiske prosesser, avgjørende for vekst, metabolisme og immunfunksjon. Blant ... -
Intermittent fasting in ongrowing Atlantic salmon (Salmo salar) reared in sea cages: Effects on feed intake, appetite control and growth
(Master thesis, 2023-11-20)Farmed Atlantic salmon are normally fed at a daily basis and fasted before operational procedures and harvest. While the biological mechanisms and effects of short and long-term fasting are largely known, there is sparse ... -
How formal initiatives to improve teaching can lead to more significant informal conversations and increased sharing practice
(Journal article; Peer reviewed, 2023)University teachers grow professionally from conversations about learning and teaching with colleagues. Significant informal conversations can be facilitated through formal activities initiated from the institutional side. ... -
Seasonality of the bacterial and archaeal community composition of the Northern Barents Sea
(Journal article; Peer reviewed, 2023)The Barents Sea is a transition zone between the Atlantic and the Arctic Ocean. The ecosystem in this region is highly variable, and a seasonal baseline of biological factors is needed to monitor the effects of global ... -
In vitro responses of fin whale (Balaenoptera physalus) fibroblasts to plasticizers and their metabolites
(Master thesis, 2024)Phthalates, plasticizers that maintain plastic’s durability and flexibility, are chemicals that leach from plastics into the environment. As endocrine disruptors, they can bind to nuclear receptors regulating metabolism ... -
Bergmann patterns in planktivorous fishes: A light-size or zooplankton community-size rule is just as valid explanation as the temperature-size rule
(Journal article; Peer reviewed, 2024)Aim Bergman patterns, the tendency of organisms to be larger at higher latitudes and lower temperatures, are a well-studied biogeographic pattern. Yet, there is no consensus on the driver or underlying mechanisms. We ... -
Short- and long-term plant and microbial uptake of 15N-labelled urea in a mesic tundra heath, West Greenland
(Journal article; Peer reviewed, 2024)Terrestrial animals are key elements in the cycling of elements in the Arctic where nutrient availability is low. Waste production by herbivores, in particular urine deposition, has a crucial role for nitrogen (N) recycling, ... -
Long-term trajectories of non-native vegetation on islands globally
(Journal article; Peer reviewed, 2023)Human-mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non-native species. However, data on past changes in non-native plant species abundance that predate ... -
Hidden in the fog: Morphological and molecular characterisation of Derogenes varicus sensu stricto (Trematoda, Derogenidae) from Sweden and Norway, and redescription of two poorly known Derogenes species
(Journal article; Peer reviewed, 2023)Derogenes varicus (Müller, 1784) is widely reported as a trematode with exceptionally low host specificity and a wide, bipolar distribution. However, several recent studies have suggested that D. varicus represents a species ... -
