Can fresh water diets influence recovery in Atlantic salmon post-smolts after SAV3 challenge in sea water?
(The University of Bergen, 2020-07-08)Pankreas sykdom (PD) forårsaket av salmonid alfavirus (SAV) er en betydelig utfordring i norsk oppdrettsnæring. Å undersøke om forskjeller i fôrsammensetning før overføring til sjøvann kan påvirke sykdommens progresjon og ...Master thesis -
The effect of keeping Atlantic salmon smolts in low salinity seawater in reducing mouthrot after seawater transfer - and the effect of freshwater as a mitigation measure against mouthrot
(The University of Bergen, 2020-07-02)Master thesis -
Development of Na+, K+ ATPase enzyme activity and expression patterns of sulfate transporters in gills, intestine and kidney during smoltification and SW acclimation in Atlantic salmon (Salmo salar L.)

Modelling fish growth under hormonal regulation as a factor in Pace of Life
(The University of Bergen, 2020-06-29)This thesis is written with the aim to increase the holistic understanding of growth in fish. As stated by Tinbergen (1963), to fully understand a behaviour or trait one needs to understand several perspectives of it. ...Doctoral thesis -
Cod spawning in the Borgundfjord Marine Protected Area
(The University of Bergen, 2020-06-27)The Norwegian coastal cod population north of 62°N declined in the years from 1997 to 2005 and has since remained low. The Borgundfjord has since 2009 served as an extractive Marine Protected Area (MPA) for protecting the ...Master thesis -
Expression of visual opsins in the retina of Atlantic salmon (Salmo salar L.) during smoltification
(The University of Bergen, 2020-06-24)Abstract: The visual system of Atlantic salmon is highly adapted to their migratory and dynamic life-history, where the profound transformational process of smoltification is crucial. The retina contain both rod- and cone ...Master thesis -
Effekt av ferskvassbehandling på gjeller hjå laks (Salmo salar L.) med amøbegjellesjukdom (AGD): gjellepatologi, prevalens og tettleik av Paramoeba perurans
(The University of Bergen, 2020-06-23)Eit av dei største problema ein opplever i sjøfasen hjå oppdrettslaks er dårleg gjellehelse. Det har eit komplekst årsakstilhøve og er ofte assosiert med eit breitt spekter av patogen. Eit av patogena som kan infisere ...Master thesis -
PARP-1: A novel polyphosphoinositide effector protein
(The University of Bergen, 2020-06-19)Polyphosphoinositides (PPIns) are a family of seven signalling lipids that are important for many cellular processes. While their functional roles in the cytoplasm have been extensively studied, their roles in the nucleus ...Master thesis -
A unique insight into repeat spawning in Atlantic salmon, using DNA profiling in the river Etne

Metabolic disorders: role of pregnane X receptor, fibroblast growth factor 19 and persistent organic pollutants
(The University of Bergen, 2020-06-08)The incidence of obesity and correlated metabolic abnormalities has increased dramatically in the last decades and constitutes a huge burden on healthcare systems and economies. It is therefore important to increase our ...Doctoral thesis -
From the fjords to the rivers: Evaluating the spatial distribution of escaped farmed salmon to inform ecologically relevant management strategies
(The University of Bergen, 2020-05-08)Over the last 40 years, the relatively fast expansion of Atlantic salmon aquaculture has created new obstacles for the persistence of wild Atlantic salmon stocks where the two overlap. Now, the greatest threat to existing ...Doctoral thesis -
Host-parasite interactions between freshwater pearl mussels (Margaritifera margaritifera) and their salmonid hosts
(The University of Bergen, 2020-04-29)The freshwater pearl mussel, Margaritifera margaritifera, is an endangered bivalve which has suffered a serious decline across its Holarctic distribution. It has a complex life cycle which involves an obligate parasitic ...Doctoral thesis -
Bivalve mollusks as tools for monitoring antibiotic resistance in the marine environment
(The University of Bergen, 2020-04-29)Antibiotic resistance (AR) is a major global health concern, especially in clinical and veterinary settings. Environmental niches, including the aquatic environment, serve as a source of and/or a dissemination route for ...Doctoral thesis -
Hormone strategies as a key for understanding life history trade-offs in fish
(The University of Bergen, 2020-04-21)Animal behaviour has fascinated humans for millennia. For studying animal behaviour, evolutionary biologists have focused primarily on their ultimate fitness causes mainly using a top-down approach. In contrast, physiologists ...Doctoral thesis -
Planktivorous fish and environmental change: using mechanistic modelling to explore the underpinnings and general validity of expected responses
(The University of Bergen, 2020-03-13)The living conditions of marine and terrestrial organisms are currently changing at a rapid pace due to human activities. To predict how this will affect them, and hence to develop appropriate management and conservation ...Doctoral thesis -
Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust
(American Society for Microbiology, 2020-03-10)Oceanic ridge flank systems represent one of the largest and leastexplored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain ...Journal article -
Innate immune responses of lumpfish (Cyclopterus lumpus) : Transcriptome analysis and characterization of pro-inflammatory cytokines
(The University of Bergen, 2020-03-05)In recent years, lumpfish and different species of wrasse are used as cleaner fishes for removal of sea lice from farmed Atlantic salmon in Europe and Canada. The production is successful, but there are challenges with ...Doctoral thesis -
Specification and differentiation of neural cells in Nematostella vectensis
(The University of Bergen, 2020-02-21)During embryonic development, early neurogenesis can be divided into several components, such as the origin, proliferation and movement of neural stem cells and progenitor cells, which are regulated by conserved genes ...Doctoral thesis -
Adaptation of anemonefish to their host anemones: From Genetics to Physiology
(The University of Bergen, 2020-02-21)The mutualism between anemonefish and anemones can be studied in terms of permanent or temporary adaptation of fish toward their host anemones. This thesis explores this theme, and aims to test (1) Whether a mutual ...Doctoral thesis
