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 ... -
Ecological Consequences of Ash Dieback in Western Norway
(Master thesis, 2021-06-30) -
Eelpouts diet in the Barents Sea: variation between species, areas, fish length and sex
(Master thesis, 2019-06-22)he eelpout family is one of the most common fish families in the Barents Sea. Despite the diversity and wide distribution, we have little information about their ecology, feeding preferences and interaction with other fish. ... -
Effect of continuous aerobic exercise on the heart of Atlantic salmon
(Master thesis, 2023-06-02) -
Effect of different arachidonic acid levels in broodstock diet on egg quality of ballan wrasse (Labrus bergylta)
(Master thesis, 2021-07-31)The production of ballan wrasse (Labrus bergylta) is growing and is becoming a focus area for the aquaculture industry. As a result of rising louse numbers and problems with resistance, biological methods such as cleaner ... -
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 ... -
Effect of sex ratio variation on mating behaviour in a parasite, the salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2020-09-01)In sexual organisms, females produce large gametes and their reproductive success is generally more limited by resources compared to males that produce many small gametes and are more limited by the number of mates. Because ... -
Effect-directed toxicity assessment of sediments from Bergen harbour (Norway) using luciferase reporter gene and cell-based bioassays
(Master thesis, 2022-10-01)Bergen harbour has been a historically polluted area in line with the harbours of many other major coastal cities in Norway and other countries around the world. With pollutants accumulating to toxic levels in organisms ... -
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 ... -
Effects of dietary fermented sugar kelp (Saccharina latissima) on Atlantic salmon (Salmo salar) intestinal morphology and redox status
(Master thesis, 2022-06-01)The aquaculture industry is the world’s fastest growing food production sector and there is a demand for new feed ingredients from lower marine trophic levels to replace the marine and vegetable resources now used in ... -
Effects of multiple mating and male harassment on female fecundity and longevity in the seed beetle Callosobruchus maculatus.
(Master thesis, 2019-12)Polyandry is a common mating system in many species, however females may experience considerable costs related to multiple mating including male harassment, energy use and in some cases physical damage. Male harassment of ... -
Effects of photoperiod regimes and salinity on Na+, K+-ATPase α-isoform expression in gills and kidney during smoltification in Atlantic salmon (Salmo salar) in recirculating aquaculture systems
(Master thesis, 2023-06-02)Understanding the molecular mechanisms of smoltification and seawater adaptation in Atlantic salmon (Salmo salar) is crucial for optimizing smolt production in aquaculture. This study investigated the expression patterns ... -
Effects of temperature regimes on proportion of early maturation and the activation of the BPG axis in male Atlantic salmon (salmo salar L.) postsmolts
(Master thesis, 2023-06-02)Early maturation of Atlantic salmon (salmo salar L.) male postsmolts is a growing concern for the Norwegian aquaculture industry due to an increasing occurrence in intensive rearing facilities, negatively impacting growth, ... -
Effects of vgll3 on maturation and its interaction with salinity in Atlantic salmon (Salmo salar, L)
(Master thesis, 2021-06-17)New emerging strategies in the production of Atlantic salmon (Salmo salar), for instance post-smolt and big smolt in land-based facilities experience maturation. High production rates, such as 24 hours photoperiods and ... -
Effekt av miksotrof vekst på biomasse- og lipidproduksjon hos Phaeodactylum tricornutum og Isochrysis galbana - en bioteknologisk tilnærming
(Master thesis, 2020-07-01)Sammendrag Mikroalger utgjør en mangfoldig gruppe av arter med stor metabolsk diversitet. Disse artene kan produsere en rekke kommersielt interessante produkter som kan brukes i human næringsmiddelindustri, helsekost, ... -
Effekt av termisk avlusing på gjellehelse hos laks: Hos patogenfri laks og i kommersiell produksjon på Vestlandet
(Master thesis, 2020-06-12)Målet med dette studiet var å studere effektane av termisk avlusing på gjellehelsa til laks. Lakselus utgjer eit stort problem for norsk lakseoppdrett, og behandlingsmetodane er avgrensa grunna resistens mot fleire medikament. ... -
Effekt av termisk avlusning på gjellehelse hos atlantisk laks (Salmo salar) holdt i nedkjølt ferskvann
(Master thesis, 2023-06-02)Gjelleproblematikk er en stor utfordring i norsk lakseoppdrett, og årsakene er ofte multifaktorielle. En del av problematikken omfatter ivaretakelse av gjellehelsen under ulike mekaniske avlusningsmetoder. Termiske avlusninger ... -
Effekten av digitale identifiseringsverktøy på videregående elevers motivasjon og læring ved artsidentifisering: Et selvbestemmelsesteoretisk perspektiv
(Master thesis, 2022-06-01)Artsidentifisering utgjør et nyttig bidrag til å forfremme artskunnskaper, som videre har positive følger for forståelse av økologiske sammenhenger. Et felt som dekker store deler av kompetansemålene innen naturvitenskap ...
