A Modeling Study of Behavior and Sampling Bias Introduced by Artificial Light on Marine Organisms During the Polar Night
(Master thesis, 2023-06-02) -
A pilot study of lumpfish (Cyclopterus lumpus) skin health, reared with three different treatments in land-based facilities and commercial net-pens
(Master thesis, 2021-06-01)Biological delousing by the means of deploying cleanerfish is one of the methods applied in Atlantic salmon aquaculture to combat the sea lice (lepeophtheirus salmonis) infestation problem. The method is based on the natural ... -
A study of autophagy gene expression in autoimmune Addison's disease

A study of two morphotypes of the brown algae Fucus serratus (Linnaeus) at Tjongspollen, Bømlo, Norway
(Master thesis, 2019-07-04)Abstract The genus Fucus contains several key forming species occupying rocky shores in the Northern Hemisphere. Fucus is known to have a great capacity for phenotypic plasticity and ability to expand in to marginal habitats. ... -
Activation of Atlantic cod (Gadus morhua) retinoid X receptors by organic tin compounds
(Master thesis, 2023-06-02) -
Adferd som stressmål: Atlantisk laks under fluktuerende temperaturregime.
(Master thesis, 2013-07-09)SAMMENDRAG Stressresponser hos fisk blir tradisjonelt målt med parametre som kortisolkonsentrasjon og fôrkonsum som gir mål på stress og velferd. Det man mangler er gode mål på subtile stressreaksjoner og kunnskap om hvordan ... -
Advanced CRISPR-Cas9 techniques for modulation of non-coding disease-associated genetic variants
(Master thesis, 2023-06-02)The search for genetic explanations of individual susceptibility to complex polygenic diseases has greatly intensified in recent years, with GWAS studies having successfully linked several hundred thousand genomic loci to ... -
Applying fisheries data from the Norwegian reference fleet to study the demersal biodiversity and fisheries dynamics in two coastal areas
(Master thesis, 2019-06-05)It is well established that biodiversity varies throughout the year, over many years and between areas, and that biodiversity plays an important role in the overall health and resilience of an ecosystem. As fisheries ... -
Are migration timing estimates based on tagged Atlantic salmon smolts (Salmo salar) biased?
(Master thesis, 2020-06-20)Telemetry tags (e.g. PIT- or acoustic tags) are increasingly used in management to monitor the migration timing of Atlantic salmon smolts (Salmo salar). Recent findings, however, suggest that tagged fish consistently migrate ... -
Ascaridoid nematodes in mesopelagic fish (Cape Verde - Bay of Biscay areas): ecological and food safety perspectives
(Master thesis, 2021-04-05)The total amount of mesopelagic fish biomass is estimated to be between 1 and 20 billion tons globally. However, there is currently no industrial fishery for them. As the sustainability of harvesting pelagic fishes and the ... -
Avfallsvann som et alternativt dyrkingsmedium for mikroalger med et høyt innhold av EPA og DHA
(Master thesis, 2020-07-02)Mikroalger har mulighet til å danne flere ulike komponenter av kommersiell verdi. Av spesielt stor interesse er deres innhold av de flerumettede fettsyrene eikosapentaensyre (EPA) og dokosaheksaensyre (DHA). Disse fettsyrene ... -
Behavioral and depth preference for wrasse (Labridae) used as cleaner fish in salmon aquaculture
(Master thesis, 2023-06-02)Wild and farmed wrasse are used as cleaner fish in Norwegian salmon aquaculture as a biological remedy against the ectoparasite salmon lice. For wrasse to be a well-functioning cleaner fish, it is essential that the species ... -
Biologilærarar sine kunnskapar om arbeidsminnet
(Master thesis, 2022-06-01)Arbeidsminnet er ein funksjon i hjernen for å mentalt manipulere informasjon. Arbeidsminnet har avgrensa kapasitet og varigheit, noko som er sentralt i undervisningssamanheng fordi det påverkar elevar sine evner til å ... -
Brakkvannstoleranse hos ulike stammer av lakselus (Lepeophtheirus salmonis)
(Master thesis, 2024-06-03)Lakselus (Lepeophtheirus salmonis) er en marin ektoparasitt som lever på laksefisk. Den skaper sykdoms- og velferdsproblemer hos både vill og oppdrettet laksefisk i Norge, og påfører oppdrettsnæringen store økonomiske ... -
