(Master thesis, 2023)Gytetid hos Atlanterhavslaks i norske vassdrag ble i 1988 studert av Tor G. Heggberget. Han fant at tiden laksen gyter på varierer fra midten av oktober til midten av januar, og at laksen gyter på gjennomsnittstemperaturer ... -
Haul-out Behavior of Harbor Seals (Phoca vitulina) along the Norwegian Coast
(Master thesis, 2021)How do selected environmental factors affect haul-out behavior of harbor seals in Skagerrak and in northern Norway? Does the probability of hauling out differ between the geographical areas? -
Haulout patterns of harbour seal (Phoca vitulina) colonies in the Norwegian Skagerrak, as monitored through time-lapse camera surveys
(Master thesis, 2023)Harbour seals (Phoca vitulina) are a part of the Norwegian coastal ecosystem and are distributed along the coastline, amongst the humans inhabiting and/or visiting these areas. We need to gain a better understanding of how ... -
Homing ability of goldsinny wrasse (Ctenolabrus rupestris) and corkwing wrasse (Symphodus melops)
(Master thesis, 2022)Wrasse family (Labridae) are widely used as a cleaner fish in salmonid aquaculture to remove the sea lice infestation. Goldsinny wrasse and corkwing wrasse are the most used wrasse fishes in the aquaculture industry in ... -
Homing Ability of Goldsinny Wrasse (Ctenolabrus rupestris)
(Master thesis, 2021)After the discovery of delousing abilities of temperate wrasses, several wrasse species are increasingly harvested in Norway and supplied to salmonid aquafarms to combat sea lice infestations. An increased ... -
Identifying protists along the Agder coastline using Illumina sequencing
(Master thesis, 2022)Environmental quality, sustainability and functioning of marine ecosystems are closely linked to species richness and diversity. Microalgae play key roles in coastal ecosystems contributing significantly to carbon flux ... -
Impacts of ghost fishing on European lobster (Homarus gammarus) and brown crab (Cancer pagurus) in Raet national park, Norway
(Master thesis, 2022)Lost fishing gear pose a threat to marine life in large parts of the world. Fishing gear have the potential to continue to fish for a long time after it has been lost, referred to as “ghost fishing”, an issue which has ... -
In deep water: Long-term trends in demersal fish diversity in Skagerrak and the Norwegian trench
(Master thesis, 2023)Throughout history, human activities have had profound impacts on marine ecosystems, with clear evidence of these consequences observable in the Skagerrak region. Oceans have historically been a critical resource for ... -
