Microbial endocrinology and fish pathogenic bacteria
(Master thesis, 2024-06-03)Yersiniosis caused by Yersinia ruckeri and pasteurellosis caused by “Pasteurella atlantica gv. salmonicida” are bacterial diseases presenting substantial welfare challenges for Atlantic salmon in Norway. In recent years, ... -
Microparasites in selected populations of wild Atlantic salmon (Salmo salar) in Norway – Prevalence, density and diversity
(Master thesis, 2019-06-26)The aim of this study was to investigate the prevalence, density and diversity of microparasites in Atlantic salmon from selected populations in Norway including and to provide an assessment of the possible spreading of ... -
Microplastic in subsurface water in the South Pacific Ocean
(Master thesis, 2023-07-01)Microplastic (MP) in the world’s oceans is a global concern. Studies on MP are frequently published, but there is limited information on MP in the South Pacific Ocean. Here, a seawater filtration unit collected MPs down ... -

Molekylær karakterisering og analyse av uttrykkingsmønsteret til T-cellemarkørene CD4-1 og CD8-alfa i berggylt (Labrus bergylta)
(Master thesis, 2021-06-01)Proteinene CD4-1 og CD8-alfa er essensielle ko-reseptorer på T-celler, og nyttige markører for å identifisere bestemte sub-populasjoner av celler i immunforsvaret. Målet med denne oppgaven var å karakterisere disse molekylene ... -
Morphometric Relationships as Indicators of Sexual Maturation in Atlantic Salmon (Salmo salar)
(Master thesis, 2023-09-01)This study aimed to identify morphometric relationships in fish that could serve as indicators for status on sexual maturation in Atlantic salmon (Salmo salar). To achieve this, 250 salmon were netted out and individually ... -
Nest predation, reproductive investment, and environmental variability in Atlantic puffin (Fratercula arctica)
(Master thesis, 2021-06-30)For many species of birds, nest predation is one of the leading causes of reproductive failure. This has been especially apparent in island nesting seabirds, which have experienced rapid declines due to the introduction ... -
Optimising cell wall disruption of microalgae biomass for release of nutrients and bioactive compounds for aquafeed and food applications
(Master thesis, 2019)Microalgae are photosynthetic organisms and primary producers of essential nutrients in the aquatic food chain. Although currently less exploited, microalgae culture can provide nutrients to cover the increasing demand for ... -
Otolith growth of herring (Clupea harengus) and sprat (Sprattus sprattus) in the Norwegian fjords
(Master thesis, 2022-06-01)Small pelagic fish play an important role in the ecosystem and are an important economical resource. The two most abundant pelagic fish in the Norwegian fjords are herring and sprat. It is documented that offshore sprat ... -
Palaeovegetation and environment during Weichselian stadials and interstadials at Mamontovaya Kurja and Sokolova in the Pechora basin, northern Russia
(Master thesis, 2000)The vegetation and climate history of the Pechora area of northwestern Russia during the Early- and Mid Weichselian have been studied. Sediments from two sites have been analysed in this study; from Sokolova and Mamontovaya ... -
Paramoeba perurans and AGD in Norwegian aquaculture: effect of freshwater treatment against AGD on gill health in commercial production of Atlantic salmon (Salmo salar L.) and experimental testing of virulence of Paramoeba perurans
(Master thesis, 2021-06-11)Gill diseases are a major and increasing challenge with respect to fish health and welfare during the marine stage in Atlantic salmon farming. The causative agents for gill diseases are complex, and several pathogens are ...
