Characterization of mitochondrial respiration in Atlantic salmon (Salmo salar) fed with glutamate and succinate enhanced diet
(Master thesis, 2018)The smolt stage of salmon has challenges in reaching adequate growth rates due to the changing environmental conditions at sea. Therefore, it is necessary to provide adequate diets to achieve sufficient growth. The present ... -
Characterization of new putative adhesion factors in Shiga toxin-producing Escherichia coli
(Master thesis, 2018)Worldwide nearly 2.8 million people are infected by STEC with acute illness, among them approximately 0.14% lead to HUS and 0.008% lead to death. Shiga toxins are essential virulence factors of STEC, but also other factors ... -
Characterization of Nitrogen Dynamics in Different Recirculation Systems
(Master thesis, 2016)The need to reduce freshwater consumption in global food production has long been recognized. Food production in single- and multi-species recirculation systems offers advantages in terms of reduced water and energy ... -
Characterization of planktonic sea lice distribution and association to fish farm installations
(Master thesis, 2017)Lepeoptheirus salmonis (Krøyer 1837) and Caligus elongatus (Normann 1832) are the sea lice species posing the biggest threat to both farmed and wild salmonid stock in the Northern hemisphere today. The three first stages ... -
Characterization of the Cytochrome p450 Family in the unique Diatom Seminavis robusta
(Master thesis, 2012)This thesis describes the cytochrome p450 superfamily in the pennate diatom Seminavis robusta. This diatom has a benthic way of life and can adhere to surfaces, and is a new candidate model organism representing the pennate ... -
Characterization of the initial ammonium uptake in Saccharina latissima - Possible implications for cultivation in an IMTA system with intensive salmon farming
(Master thesis, 2018)Production of Atlantic salmon (Salmo salar) results in a release of ca. 39% of the total nitrogen content from the feed, which is mainly released as dissolved inorganic nitrogen (DIN), and mainly as the metabolic by product ... -
Characterization of three novel genes encoding postulated peptides of the IDA family, and their possible function in plant defense in Arabidopsis thaliana
(Master thesis, 2011)IDL6 and IDL7 are postulated peptides of the INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) peptide family in the model organism Arabidopsis thaliana. The genes encoding the postulated peptides, IDL6 and IDL7, were investigated ... -
Characterizing Hydrolicer treatment of Lepeophtheirus salmonis on farmed salmon
(Master thesis, 2021)Lakselusen, Lepeophteirus salmonis, har siden starten av lakseoppdrett vært en utfordring for fiskevelferd og vekst. For å beskytte villaksbestandene og oppdrettslaksen er lakseoppdrettsnæringen i henhold til loven forpliktet ... -
Characterizing morphological (co)variation using structural equation models: Body size, allometric relationships and evolvability in a house sparrow metapopulation
(Peer reviewed; Journal article, 2019)Body size plays a key role in the ecology and evolution of all organisms. Therefore, quantifying the sources of morphological (co)variation, dependent and independent of body size, is of key importance when trying to ... -
Chemical composition and release rate of waste discharge from an Atlantic salmon farm with an evaluation of IMTA feasibility
(Journal article; Peer reviewed, 2013)The carbon (C), nitrogen (N) and phosphorus (P) compositions of salmon feed, fish and faeces were studied at a salmon farm in Badstuvika (63°31’N, 9°9’E) in central Norway. These data were used to estimate the release rates ... -
Chemical composition of selected marine microalgae, with emphasis on lipid and carbohydrate production for potential use as feed resources
(Peer reviewed; Journal article, 2021)Marine microalgae are a promising sustainable source of lipids, omega-3 fatty acids, and carbohydrates. Selected microalgae species belonging to the Bacillariophyceae, Haptophyceae, Eustigmatophyceae, and Prasinophyceae ... -
Chemical Effects of Common Plastic Products: Baseline Toxicity Screening and Chronic Toxicity to Polychaetes
(Master thesis, 2021)Plast lages av polymerer som kombineres med en rekke tilsetningsstoffer for å oppnå ønskede funksjoner og egenskaper. Disse tilsetningsstoffene, samt utilsiktet tilsatte stoffer og andre absorberte stoffer, kan fungere som ... -
Chemical Emissions from Indoor Materials in Residential Buildings; A Systematic Mapping Study
(Master thesis, 2017)Exposure to residential emissions have previously been associated with adverse effects on wellness and productivity of the building occupants. This systematic mapping study was conducted with an aim to visually map together ... -
Chicken hydrolysate as an alternative feed ingredient for Atlantic salmon (Salmo salar) - effects on growth, feed intake, digestibility and intestinal health
(Master thesis, 2023)Dette forsøket undersøkte effekten av å gi formulert fôr til postsmolt av atlantisk laks (Salmo salar) der 22% og 64% av fiskemelet ble byttet ut med henholdsvis 5% og 15% kyllinghydrolysat. Kyllinghydrolysatet inneholdt ... -
Chp8, a diguanylate cyclase from pseudomonas syringae pv. Tomato DC3000, suppresses the pathogen-associated molecular pattern flagellin, increases extracellular polysaccharides, and promotes plant immune evasion
(Journal article; Peer reviewed, 2014)The bacterial plant pathogen Pseudomonas syringae causes disease in a wide range of plants. The associated decrease in crop yields results in economic losses and threatens global food security. Competition exists between ... -
Chronic unpredictable stress induces anxiety-like behaviors in young zebrafish
(Peer reviewed; Journal article, 2020)Exposure to stress during early life affects subsequent behaviors and increases the vulnerability to adult pathologies, a phenomenon that has been well documented in humans and rodents. In this study, we introduce a chronic ... -
