Applying fisheries data from the Norwegian reference fleet to study the demersal biodiversity and fisheries dynamics in two coastal areas
(Master thesis, 2019-06-05)It is well established that biodiversity varies throughout the year, over many years and between areas, and that biodiversity plays an important role in the overall health and resilience of an ecosystem. As fisheries ... -
Aquaculture-driven evolution of the salmon louse (Lepeophtheirus salmonis) mtDNA genome
(Master thesis, 2022-06-01)Widespread resistance towards pyrethroids, a pesticide that has been extensively used in salmonid aquaculture to control sea lice, is reported in the salmon louse (Lepeophtheirus salmonis). The resistance mechanism has ... -
Are migration timing estimates based on tagged Atlantic salmon smolts (Salmo salar) biased?
(Master thesis, 2020-06-20)Telemetry tags (e.g. PIT- or acoustic tags) are increasingly used in management to monitor the migration timing of Atlantic salmon smolts (Salmo salar). Recent findings, however, suggest that tagged fish consistently migrate ... -

(Master thesis, 2011-10-03)Denne studien av artssuksesjon og reguleringsmekanismer er satt sammen av to deler. Den ene delen består av et tokt til Svinøysnittet, mens den andre er en serie av prøvetakinger og målinger i Raunefjorden i Hordaland. ... -
Assessing mackerel behaviour following crowding-induced stress in purse seine fisheries
(Master thesis, 2016-06-01)The practice of slipping in purse seine fisheries has been shown to cause high levels of delayed mortality in released fish. This unaccounted mortality could lead to bias in stock assessments, and brings the sustainability ... -
Assessment of the biodegradability of xanthan in offshore injection water
(Master thesis, 2015-04-29)The application of biopolymers in EOR operations is considered environmental friendly compared to synthetic polymers. However, microbial degradation of the biopolymers may lead to a deterioration of effect in EOR applications. ... -
Avfallsvann som et alternativt dyrkingsmedium for mikroalger med et høyt innhold av EPA og DHA
(Master thesis, 2020-07-02)Mikroalger har mulighet til å danne flere ulike komponenter av kommersiell verdi. Av spesielt stor interesse er deres innhold av de flerumettede fettsyrene eikosapentaensyre (EPA) og dokosaheksaensyre (DHA). Disse fettsyrene ... -
Barents Sea capelin and us; Do they really mature and migrate at 14cm? Or have we become prisoners in our own Platonic allegory? How shall we respond?
(Master thesis, 2018-06-15)Capelin (Mallotus Villosus) are an important component of the Barents Sea ecosystem. As zooplankton consumers they play a role in channelling energy up the food web, and they have the potential to represent a biomass of ... -
