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 ... -
Breakdown of keratin-laden biomass waste by the thermophilic bacterium Fervidobacterium pennivorans strain T
(Master thesis, 2020-06-30)Developing a more sustainable agro-industry has become a necessity in light of the current environmental crisis. Biocatalysts are already adopted in many industrial applications and have quickly optimized, and in some cases ... -
Bumblebee communities in open and overgrown heathlands in Nordhordland UNESCO Biosphere, Vestland, Norway
(Master thesis, 2023-06-01)Insect pollinators such as bumblebees (Bombus spp.) play a vital role in the pollination of wild and cultivated plants and is therefore critical for ecosystem services and food security worldwide, especially in northern ... -

Can catch data from small meshed gears in shallow waters be used to estimate recruitment indices of Norwegian coastal cod, Northeast Arctic saithe and pollack along the Norwegian coast?
(Master thesis, 2019-06-21)Shallow waters (<30 meters) are important nursery areas for coastal cod, saithe and pollack, before they recruit to their respective fisheries at an age around 3 years old. Still, no study provides information on fish ... -
Can environmental toxins increase parasite fitness? Ecotoxicological studies on the effects of microcystin on the host-parasite dynamics of Schistocephalus solidus
(Master thesis, 2020-08-21)Background: Eutrophication of aquatic biomes and exacerbated climate change effects are expected to result in a global increase in harmful cyanobacterial blooms. Cyanotoxins are detrimental to animal health, but how they ... -

Characterization of the pregnane X receptor (PXR) from European hake (Merluccius merluccius): cloning, ligand activation, and bioinformatical analyses
(Master thesis, 2022-09-08)As a response to adverse environmental conditions, organisms have throughout evolution generated a collection of gene families and pathways providing protection and repair of damage caused by physical, chemical, and ... -
Characterizing the Infectious Pattern of Viruses Infecting the Haptophyte Emiliania huxleyi
(Master thesis, 2019-06-21)Marine viruses play an important role in biodiversity, population abundance and biogeochemical cycling of elements in the environment. They exhibit a broad range of infectious patterns and it is of ecological interest to ... -

"A cleaner break" - Genetic analysis identifies two major groups of ballan wrasse (Labrus bergylta) within Scandinavia and evidence of phenotype derived divergence
(Master thesis, 2019-06-21)For a long time, sea lice have represented the major financial and fish welfare challenge of the salmonid farming industry. In the late 1980s, the use of parasite-eating cleaner fish, first and foremost wrasses (family ... -
Co-infection of Atlantic salmon (Salmo salar) by Lepeophtheirus salmonis and Moritella viscosa
(Master thesis, 2019-06-20)A co-infection is defined as an infection with two or more different pathogens, where the pathogens can either have a synergistic or antagonistic effect or alternatively not affect each other at all. Lepeophtheirus salmonis ... -
Community composition, population structure and phylogeny of coastal sympagic meiofauna in eastern Svalbard
(Master thesis, 2019-06-19)Coastal sea ice communities constitute a highly vulnerable yet little investigated part of the Arctic ecosystem. A better understanding of the Arctic sea ice ecosystem will aid in more accurate predictions of the ecological ... -
Comparing density of lumpfish (Cyclopterus lumpus) used in aquaculture to different welfare indicators
(Master thesis, 2021-05-31)Farmed lumpfish are commonly used as cleaner fish in the salmonid aquaculture industry, but a knowledge gap exists with regards to their density. Filling this knowledge gap is of importance, as the lumpfish have no swim ... -
