The role of crawling predators in the decline and distribution of blue mussels in Norwegian coastal waters
(Master thesis, 2022-08-22)Blue mussels (Mytilus spp.) are declining in coastal areas around the world. In Norway, they thrive on floating structures, while on rocky shores they have widely disappeared. Proposed and elsewhere reliable drivers such ... -
The role of marine nutrients in 2,3,7,8-tetrachlorodibenzo-p-dioxin toxicity in vitro and in vivo
(Master thesis, 2022-06-01)2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is the most potent dioxin congener and is associated with several adverse health effects. As a result of its high lipophilicity and slow degradation the compound easily accumulates ... -
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 ... -
The small-scale fisheries of Timor-Leste and the impacts of the COVID-19 pandemic
(Master thesis, 2021-08-02)Small-scale fisheries (SSFs) of developing countries are an important yet neglected part of the world’s capture fisheries. The general lack of fisheries dependent and independent data makes it difficult to predict the ... -
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 ... -
Tissue tropism and optimization and evaluation of diagnostics test for the detection of Pilchard orthomyxovirus (POMV) in Atlantic salmon (Salmo salar)
(Master thesis, 2020-06-12)Since 2012, pilchard orthomyxovirus (POMV) has been of major concern to the Tasmanian salmonid industry. The virus was first discovered in pilchards, and is, so far, only shown to be highly infectious to Atlantic salmon ... -
Tolerance limits to fluctuating water currents in Atlantic salmon (Salmo salar): A novel method to simulate the impact of ocean waves on salmon welfare in the laboratory
(Master thesis, 2023-06-02)The Norwegian aquaculture industry aims to expand the production of Atlantic salmon (Salmo salar) to offshore locations where the fish will be experiencing more extreme weather conditions compared to traditional sheltered ... -
Towards a challenge model for the tapeworm Eubothrium crassum - incubation of cestode eggs and maintenance of a marine intermediate host, Acartia tonsa
(Master thesis, 2022-06-01)Bendelormen Eubothrium crassum Bloch (Cestoda: Bothriocephalidea) er en parasitt som forekommer hovedsakelig hos laksefisker i både ferskvann og sjøvann. Den er et økende problem i norsk oppdrettslaks (Salmo salar Linnaeus) ... -
Tracking the time course of reproductive events in the Northeast Arctic haddock (Melanogrammus aeglefinus)
(Master thesis, 2021-06-15)An important objective of fisheries management is to ensure harvest rates that allows the population to maintain its reproductive potential over time. Reproductive biology is thus of key importance when managing a fish ... -
Trichlorfon, a salmon lice pesticide, and the effect on metabolism and inflammation in Atlantic salmon (Salmo salar, L.)
(Master thesis, 2020-06-26)Since the beginning of the salmon farming industry in Norway, the substantial fish health and welfare and economic costs caused by the parasitic salmon lice (Lepeophtheirus salmonis) has increased in tandem with the expanding ... -
Trophic structure of mesopelagic species in the Northeast Atlantic Ocean based on stable isotopes of carbon and nitrogen
(Master thesis, 2021-09-03)The mesopelagic zone is one of the largest, yet among the least explored habitats of the planet. Possible estimates of fish living in this zone range from around 1 to 15 billon tones of biomass which is 10 to 15 times that ... -

(Master thesis, 2020-06-18)Denne masteroppgaven har som formål å undersøke og beskrive elevers interesse for å lære biologi ved å benytte klyngeanalyse til å identifisere elevtyper. Oppgaven bruker et kvantitativt forskningsdesign med spørreskjema ... -
USING LIGAND-ACTIVATED RECEPTORS FROM ATLANIC COD (Gadus morhua) AND ZEBRAFISH (Danio rerio) TO ASSESS BIOLOGICAL EFFECTS OF PHARMACEUTICALS IN WASTEWATER IN BERGEN, NORWAY
(Master thesis, 2021-09-01)Pharmaceuticals and personal care products are continuously released into the marine environment through wastewater. Understanding the possible biological implications of pharmaceuticals specifically may be particularly ... -
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 ... -
Valorisation of waste streams from recirculating aquaculture systems by photoautotrophic microalgae
(Master thesis, 2022-09-11)The low water consumption in Recirculating Aquaculture Systems (RAS) can result in relatively high concentrations of polluting nutrients in effluent waste streams (WSs) compared to traditional Flow-through systems (FTS). ... -
