(Master thesis, 2021-05-15) -
Immunrespons hos atlantisk laks (Salmo salar) ved infestasjon av lakselus (Lepeophtheirus salmonis): Endringer i genuttrykk og histologiske forandringer i hud
(Master thesis, 2021-06-01)Sammendrag Lakselus blir ansett som den største utfordringen knyttet til oppdrett i dag. Disse utfordningene kommer i form av redusert fiskehelse, økte produksjonskostnader samt tiltak og lovverk som begrenser vekst for ... -
Welfare and efficiency of warm and cold waterfall (low pressure flushing) as delousing treatment of Atlantic salmon (Salmo salar)
(Master thesis, 2021-06-01)Salmonid aquaculture plays an important role in increasing global fish production and the biggest factor constraining its further growth and development in Norway is salmon lice (Lepeophtheirus salmonis). Previous projects ... -
Refilling behaviour of Atlantic salmon (Salmo salar) with different air-dome heights
(Master thesis, 2021-06-01)The increased salmon lice (Lepeophtheirus salmonis), issue causes welfare concerns in salmon aquaculture industry. The resistance of lice to different medicinal treatments has led research to increasingly focus on preventive ... -
Spatiotemporal dynamics in the acoustic backscatter of plankton and lesser sandeel (Ammodytes marinus) in the North Sea measured using a Saildrone
(Master thesis, 2021-06-01)With accelerating global warming and human activities, the North Sea is one of the marine ecosystems undergoing rapid change. The need for spatially-temporally extendable survey platforms for assisting well-established ... -
The effects of geodiversity on temporal shifts in alpine plant communities.
(Master thesis, 2021-05-31)Climate warming is inducing compositional shifts in alpine species communities across Europe. However, there are variations in the magnitude and direction of these shifts related to variations in the abiotic environment. ... -
Metagenomics-based discovery of novel carbohydrate degrading enzymes from deep-sea hydrothermal in situ enrichments; expression, purification and characterization
(Master thesis, 2021-06-01)Deep sea hydrothermal vents located along ocean ridges harbor microorganisms with unique adaptations. These extremophiles have adapted to high temperature and extreme conditions. Carbohydrate acting enzymes with thermostable ... -
Validation of Atlantic salmon (Salmo salar) weight estimation by stereo camera, and morphometric analysis for assessment of growth performance and maturation status
(Master thesis, 2021-04-26)Stereo image analysis of free-swimming farmed Atlantic salmon is today used for purposes such as individual size estimation and sea lice counting. This technology may in the future be used to score welfare and life history ... -
A descriptive analysis of data from the Norwegian Coastal Reference Fleet and comparison with catch-per-unit-effort data from research surveys
(Master thesis, 2021-03-22)Catch quotas are used for the sustainable management of fish stocks and are based on official catch statistics and research surveys. However, these methods provide only partial information, as the official catch data does, ... -
Differences in gill responses in ballan wrasse (Labrus bergylta)
(Master thesis, 2020-08-04) -
Development and application of novel measures of foregut lamina propria in Atlantic salmon given 5 different diets
(Master thesis, 2021-03-01)The trial was composed of five diets: a fishmeal/fish oil diet, a 20% soybean meal/30% fishmeal & fish oil diet, a fishmeal/rapeseed oil diet, plant protein concentrates/fish oil diet, plant protein ingredients/mix of ... -
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 ... -
Influence of temperature and feeding on early sexual maturation commitment in male Atlantic salmon (Salmo salar, L.) during the freshwater stage
(Master thesis, 2021-01-20)The intensification of Atlantic salmon (Salmo salar) post-smolt production to enhance growth performance has promoted a rise in precocious male maturation rates. Unlike traditional parr maturation, which seems to be highly ... -
Effects of chlorpyrifos, an organophosphate pesticide on the intestinal barrier of Atlantic salmon (Salmo salar)
(Master thesis, 2021-03-20)Aquaculture is the fastest growing food producing sector worldwide. The decline in capture fisheries has led to a decrease in fish oil and fish meal production. Due to this decline, there is a need for alternative lipid ... -
Microplastic in the Urban Environment - Concentrations and Sources in Streets and Sand Traps

Early studies on a novel phosphoinositide 3-kinase p110β isoform, and its localisation
(Master thesis, 2020-12-23)Phosphoionositide 3-kinase (PI3K) is a family of enzymes that are part of the PI3K signalling pathway, which is one of the most often altered pathways in human cancer. The PI3K family is divided into three classes, where ... -
Refilling behaviour of Atlantic salmon (Salmo salar) in submerged sea cages with air-dome
(Master thesis, 2020-12-19)Production of Atlantic salmon in submerged sea cages may solve surface related challenges like sea lice and toxic algae blooms but previous trials have faced problems linked to buoyancy. Korsøen et al. (2012) showed that ...
