Investigating shifts in epifaunal communities in Zostera marina meadows and Fucus serratus beds in the Norwegian Skagerrak
(Master thesis, 2024-06-03)Coastal ecosystems are under increasing pressure from climate change and other anthropogenic stressors, including along the coast of Norway. Seagrass meadows and macroalgal beds are two highly productive coastal ecosystems ... -
Miljøoverlevelse hos Spironucleus salmonicida - parasitten som forårsaker systemisk spironukleose hos oppdrettslaks
(Master thesis, 2024-06-03)Spironucleus salmonicida er en alvorlig trussel mot oppdrettsnæringen, spesielt for atlantisk laks i Nord-Norge. Utbrudd av systemisk spironukleose forårsaket av denne encellede flagellaten har ført til betydelige økonomiske ... -
Histological analysis of intestine in Atlantic Halibut (Hippoglossus hippoglossus) larvae – looking for clues to explain larval mortality
(Master thesis, 2024-06-03)The value of the Atlantic halibut (Hippoglossus hippoglossus) has increased a lot over the last years, as well as the Atlantic halibut aquaculture industry. The aquaculture industry has always dealt with problems, and one ... -
Piscine orthoreovirus-1 (PRV-1) infection dynamics: Investigation through temporal profiling of factors affecting viral susceptibility, infectiousness, and persistence in Atlantic salmon
(Master thesis, 2024-02-15)In recent years, Norway has accounted for >50% of the global commercial production of Atlantic salmon. This growth in production has also resulted in an increased emergence of several viral diseases. Heart and skeletal ... -
Pacific white shrimp (Litopenaeus vannamei) cultured in recirculating aquaculture systems (RAS). Effects of density on growth, mortality, and welfare
(Master thesis, 2024-06-03)Aquaculture is a rapidly growing industry and one of the most vital pillars in addressing the increasing global demand for food. Different farming systems and strategies have been developed to achieve more modern and ... -
The effect of dissolved oxygen on feed intake, growth and nutrient utilization in Atlantic salmon (Salmo salar)
(Master thesis, 2024-06-03)Atlantic salmon (Salmo salar) is a species of significant economic importance in aquaculture. Optimal growth and nutrient utilization are critical for the efficient production of Atlantic salmon. However, especially during ... -
Varying back-calculated growth in Atlantic herring (Clupea harengus) along the Norwegian coast based on scales and otoliths
(Master thesis, 2024-06-03)Atlantic herring display a wide spatial distribution where its numerous populations encounter various environmental factors and selective forces, thus having different prerequisites for growth. This report aims to provide ... -
Using a greenhouse experiment to test the consistency in the chemical response of Pinus sylvestris and Pinus uncinata pollen to UV-B radiation
(Master thesis, 2024-06-17)Previous studies have suggested that the amount of UV-B absorbing compounds (UAC) found in pollen grains increases when the plants are exposed to UV-B radiation. If this response is consistent across and within populations, ... -
A rational approach for estimating antioxidant capacity: from dietary fish formulations to bioreactor water samples
(Master thesis, 2024-06-03)Concern about the harmful properties of synthetic antioxidants, such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), or ethoxyquin, in fish feed has led to the banning of ethoxyquin by the European Union ... -
A study of bee flight activity in relation to flowering in a fruit-growing region in western Norway

Spatial and Temporal Variation in length-at-Age in Northeast Arctic haddock (Melanogrammus aeglefinus)
(Master thesis, 2024-06-03)Summary: The growth of fish is one of the most important factors in fisheries management. As fish grow, their lifestyles often change considerably including their food sources and the species that prey on them. Growth is ... -
The effects of gas supersaturation on the density of brown trout in two Norwegian rivers
(Master thesis, 2024-06-03)Rivers are under pressure from different stressors, one of which is gas supersaturation. Gas supersaturation occurs when the total dissolved gases (TDG) in the water exceed 100%. Unregulated rivers normally hover around ... -
A qualitative study of students’ motivations for a biology field course in Svalbard
(Master thesis, 2024-06-03)In this thesis I investigate graduate students’ motivations for choosing a biology field course at The University Centre in Svalbard (UNIS). Both students and teachers value field courses and they are considered important ... -
Hvilke effekter har konkurranse, temperatur og transplantasjon på frøproduksjon og spiringsevne hos lavlandsplanter når de er transplantert utenfor sitt nåværende utbredelsesområde?
(Master thesis, 2024-06-03)Økning av temperatur som følge av klimaendringer har ført til endringer i strukturen og sammensetningen av økosystemer, som gjør at flere plantearter har utvidet og endret utbredelsesområdet for å følge sin klimatiske ... -
Toxicological studies of marine mammals: In vitro experiments with fin whale (Balaenoptera physalus) fibroblasts and in silico studies of cytochrome P450 proteins
(Master thesis, 2024-08-19)Whales and marine mammals are an important part of the marine ecosystems, but also vulnerable for exposure to chemical pollution in the water. Studies of these animals are important for guiding our understanding of the ... -
Towards a More Robust Salmon: Using CRISPR/Cas9 editing to increase protein levels in Zebrafish and Atlantic salmon
(Master thesis, 2024-08-15)With an increasing world population, the demand for high quality food grows every year. The aquaculture industry shows promising potential as it provides nutritionally rich, affordable provisions, but is still facing ...
