Decoding Springtime Oxidation in Postsmolt Atlantic Salmon: Implications for Redox Signaling and Growth
(Doctoral thesis, 2023-09-22)Fisk er en integrert del av akvatiske økosystemer, og deres evne til å takle miljøendringer er en viktig global bekymring. Oppdrettet atlantisk laks i sjømerder er eksponert for ulike miljøforhold, inkludert endringer i ... -
Cleaner Fish Do Not Impact the Pigmentation of Salmon Lice (Lepeophtheirus salmonis) in Commercial Aquaculture Cages
(Journal article; Peer reviewed, 2023-09-10)Salmon lice are one of the biggest challenges to sustainable salmonid aquaculture. The species display high evolutionary potential, which is evident by its development of resistance to numerous chemical compounds used for ... -
Studie av retinoid X reseptorer (Rxr) og Rxr -signalveier i Atlanterhavstorsk (Gadus morhua) ved bruk av immunokjemiske of ex vivo teknikker
(Master thesis, 2023-09-04)Nuclear receptors (NRs) comprise a large superfamily of ligand-activated transcription factors. Many NRs facilitate gene expression through heterodimeric binding to retinoid X receptor (RXR). RXR is thus part of a vast ... -
The role of spatial dependency in niche shifts of invasive species
(Master thesis, 2023-09-01)Invasive species are an ongoing threat to nature and human interests. Species distribution models are used to predict the current and potential distribution of invasive species, but doing so has proved difficult. One ... -
Morphometric Relationships as Indicators of Sexual Maturation in Atlantic Salmon (Salmo salar)
(Master thesis, 2023-09-01)This study aimed to identify morphometric relationships in fish that could serve as indicators for status on sexual maturation in Atlantic salmon (Salmo salar). To achieve this, 250 salmon were netted out and individually ... -
Smitteforsøk med Lepeophtheirus salmonis på Oncorhynchus gorbuscha og Salmo salar
(Master thesis, 2023-08-28)Hovedmålet med denne studien var å teste om kopepoditter av lakselus (Lepeophtheirus salmonis) som har vært festet på pukkellaks (Oncorhynchus gorbuscha) kan smitte og etablere seg på atlantisk laks (Salmo salar) eller om ... -
Tailoring mRNA towards future vaccine for lumpfish (Cyclopterus lumpus) – Protein expression and immune responses
(Master thesis, 2023-08-01)Lumpfish plays an important role in aquaculture, where it is used to combat sea lice infestations among farmed salmon, acting as a biological alternative to chemical and physical treatment. As a relative newcomer to ... -
Elevated sea temperature combined with dietary methionine levels affect feed intake and appetite-related neuropeptide expression in the brains of juvenile cobia (Rachycentron canadum)
(Journal article; Peer reviewed, 2023-07-04)This study aimed to determine the impact of elevated temperature combined with different levels of dietary methionine concentrations on feed intake (FI) and brain expression of selected neuropeptides and one receptor ... -
Microplastic in subsurface water in the South Pacific Ocean
(Master thesis, 2023-07-01)Microplastic (MP) in the world’s oceans is a global concern. Studies on MP are frequently published, but there is limited information on MP in the South Pacific Ocean. Here, a seawater filtration unit collected MPs down ... -
Structural elements determining NAMPT activity
(Doctoral thesis, 2023-06-20)Nikotinamidadenindinukleotid (NAD) er en hydridbærer involvert i redoksreaksjoner i metabolismen. I tillegg er NAD+ et substrat av enzymer som medierer vitale NAD+-avhengige prosesser, der dinukleotidet spaltes, og frigjør ... -
The role of bioluminescent prey in the diet of two hatchetfish species and four lanternfish species in the North Atlantic Ocean in relation to eye-size
(Master thesis, 2023-06-16)The mesopelagic zone, often referred to as “the twilight zone” can be defined as the area of the ocean at 200-1000 m depth. Here, light levels vary greatly and provides a varying visual scene. At shallow depths, down-welling ... -
Effects of the emerging marine aquafeed mycotoxins beauvericin (BEA) and enniatin B (ENNB) in Atlantic Salmon (Salmo salar) – Implications on cellular pathways and functions, and tissue responses
(Doctoral thesis, 2023-06-14)Plantebaserte fôringredienser er en kilde til mykotoksinene enniatin B (ENNB) og beauvericin (BEA) for oppdrettslaks (Salmo salar). Dette har skapt bekymring for fiskehelse og fôrsikkerhet, siden disse mykotoksinene foreløpig ... -
Functional characterisation of polybasic motifs in the nucleolar PtdIns(3,4,5)P3- interacting proteins proliferation-associated protein 2G4 and poly(ADP-ribose) polymerase 1
(Doctoral thesis, 2023-06-13)Fosfoinositid 3-kinase (PI3K)-signalveien er viktig for flere cellulære prosesser, inklusiv celleoverlevelse, proliferasjon og proteinsyntese. Den er godt beskrevet i cytoplasmaet. I tillegg kan fosfatidylinositol ... -
