Investigating traditional and novel genetic markers for smoltification status in wild Atlantic salmon (Salmo salar)
(Master thesis, 2025)Atlantic salmon are anadromous fish, meaning they hatch and live their young lives in freshwater (FW), before migrating to seawater (SW) to feed and grow. The salmon must undergo physiological change to prepare for the new environment. This adaptation is called smoltification or parr-smolt-transformation (PST). One of the most obvious changes is the increasing salinity in SW. As the salmon migrates ... -

CRYOPRESERVATION OF SPOTTED WOLFFISH (Anarhichas minor) SPERM EFFECTS OF EXTENDER SUPPLEMENTED WITH ASCORBIC ACID AND SUPEROXIDE DISMUTASE ON SPERM QUALITY
(Master thesis, 2025)The spotted wolffish (Anarhichas minor) holds considerable promise for cold-water aquaculture due to its high fillet yield, docile behaviour, and resistance to disease. However, reproductive constraints—including limited sperm motility, low ejaculate volume, and narrow spawning windows—impede large-scale hatchery production. Cryopreservation offers a strategic solution for overcoming these limitations ... -
The multiple roles of whale blubber, with particular consideration of thermal conductivity and chemical composition of blubber in a high-Arctic species, the narwhal, Monodon monoceros.
(Master thesis, 2025)Blubber in marine mammals is a multifunctional tissue, serving critical roles in thermoregulation, energy storage, endocrine regulation, and hydrodynamics. By providing insulation against cold, acting as a dense energy reserve, secreting hormones such as leptin to regulate metabolism, and streamlining the body for efficient swimming, blubber supports survival in diverse and often extreme environments. ... -

Factors predicting migration patterns in the world’s northernmost moose population in Finnmark
(Master thesis, 2025)Abstract Purpose. The purpose of the study was to investigate factors predicting migration pattern in moose in Finnmark. Moose has earlier been most numerous in the central and southern part of Norway, but the moose population in Finnmark increased in the 1990’s, and has now reached a more stable state. This makes a study on how the moose behaves in a relatively new habitat of particular ... -
Seasonal dynamics in RNA:DNA ratios of marine microbial communities in a high latitude estuary
(Master thesis, 2025)Microorganisms are key players in marine ecosystems, as they form the basis of food webs and drive biogeochemical cycling. Global warming increases sea surface temperatures and the frequency of marine heatwaves, but the effect on marine microbes is still not well understood. To predict future changes of marine ecosystems, it is therefore important to understand the direct impact of increased ... -
