(Master thesis, 2022)Formal stock assessment is a key step in managing fisheries sustainably and preventing overexploitation (Hilborn, 2011). However, the majority of the world’s exploited stocks are considered data-limited and lack formal ... -
Genomic analysis of anadromous brown trout (Salmo trutta) reveals new insights into connectivity patterns and population divergence
(Master thesis, 2018)A large body of studies on brown trout genetics currently exists. However, fewer of these studies have been conducted on anadromous brown trout (sea trout) and have been limited to only a few genetic markers like allozymes, ... -
Ghost fishing in Raet National Park: estimating the impact on Atlantic cod and three species of wrasse
(Master thesis, 2022)Loss of fishing gear have been a problem for as long as fishing has occurred in the ocean. As modern fishing gear are made up of mostly synthetic materials, it will stay intact and continue to fish for a long time after ... -

(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 ... -
