Exploring the Condition of Fish Welfare and Microbial Dynamics in Egget® – a Novel Closed Aquaculture System at Sea
(Master thesis, 2023-10-02)The Norwegian Atlantic salmon (Salmo salar) aquaculture industry faces significant challenges, prompting the need for innovative approaches to enhance sustainability. One such innovation is the prototype Egget®, a novel ... -
Vgll3 knockout as a means to delay male maturity during large smolt production of Atlantic salmon (Salmo salar L.)
(Master thesis, 2023-12-01)With a 100 billion NOK export value, Atlantic salmon (Salmo salar L.) has become one of the most important export products for Norway. A highly intensified production in recirculating aquaculture systems (RAS) has pushed ... -
The effects of stream channelization on salmonid habitats in western Norway
(Master thesis, 2023-11-20)Amidst the Anthropocene era’s heightened human influence on the environment and escalating habitat degradation, this study delves into the impacts of channelization on salmon and sea trout habitats in small streams in ... -
Tilrettelegging for elever med lese- og skrivevansker under praktisk arbeid i biologi. En kvalitativ studie av læreres kunnskaper om og tilrettelegging for elever med lese- og skrivevansker under praktisk arbeid i biologi i videregående skole
(Master thesis, 2023-11-20)Biologifaget inneholder abstrakte og komplekse prosesser og teorier som kan føre til vanskeligheter med å tilegne seg kunnskapen særlig for dem som har lese- og skrivevansker. Praktisk arbeid kan være spesielt viktig fordi ... -
The effect of high and low particle load on smoltification of Atlantic Salmon (Salmo salar) in RAS
(Master thesis, 2023)This study explores the effect of high and low Total Suspended Solids (TSS) on smoltification, and ion regulation of Atlantic salmon (Salmo salar) reared in a Recirculating Aquaculture System (RAS). As the salmon aquaculture ... -
Adferd som stressmål: Atlantisk laks under fluktuerende temperaturregime.
(Master thesis, 2013-07-09)SAMMENDRAG Stressresponser hos fisk blir tradisjonelt målt med parametre som kortisolkonsentrasjon og fôrkonsum som gir mål på stress og velferd. Det man mangler er gode mål på subtile stressreaksjoner og kunnskap om hvordan ... -

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 ... -
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 ... -
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 ... -
Studies of retinoid X receptors (Rxr) and the Rxr-signaling pathway in Atlantic cod (Gadus morhua) using immunochemical and ex vivo approaches
(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 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 ... -
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 ... -
