Skin development in Atlantic salmon (Salmo salar) post-smolts reared in freshwater or low strength seawater and effect on susceptibility to Tenacibaculum finnmarkense
(Master thesis, 2020-06-24)Ulcer development caused by bacterial infections in the sea is a large problem in the Norwegian salmon farming industry, leading to increased mortalities, reduced fish welfare, down-classification at harvest, and increased ... -
Smitteforsøk med Lepeophtheirus salmonis på Oncorhynchus gorbuscha og Salmo salar
(Master thesis, 2023-08-28)Hovedmålet med denne studien var å teste om kopepoditter av lakselus (Lepeophtheirus salmonis) som har vært festet på pukkellaks (Oncorhynchus gorbuscha) kan smitte og etablere seg på atlantisk laks (Salmo salar) eller om ... -
Soft-Bottom Ecological Status and Distribution of Leptosynapta sp. in Kviturspollen
(Master thesis, 2022-06-01)This thesis aims to give an overview of the current ecological status of Kviturspollen by using CTD data and soft-bottom samples to evaluate the conditions, and results from past surveys to evaluate any improvement or ... -
Spatial variability in life history traits of sprat (Sprattus sprattus) in Norwegian fjords suggests low mixing of adults between the fjords
(Master thesis, 2022-06-01)Recent studies have shown almost no genetic variability of sprat (Sprattus sprattus) among Norwegian fjords. However, each fjord creates its own unique habitat, and local adaptations can thereby be expected. An annual ... -
Spatiotemporal dynamics in the acoustic backscatter of plankton and lesser sandeel (Ammodytes marinus) in the North Sea measured using a Saildrone
(Master thesis, 2021-06-01)With accelerating global warming and human activities, the North Sea is one of the marine ecosystems undergoing rapid change. The need for spatially-temporally extendable survey platforms for assisting well-established ... -
Spatiotemporal variation in the density distribution of sprat (Sprattus sprattus) in Hardangerfjorden and Sognefjorden
(Master thesis, 2022-06-01)Sprat (Sprattus sprattus) is a pelagic fish species of considerable importance for the Norwegian fjord ecosystems, especially in Sognefjorden and Hardangerfjorden. Coastal habitats like fjords are heavily impacted by human ... -
Spawning during an oil spill: how exposure to the water-accommodated fraction of crude oil may disrupt polar cod (Boreogadus saida) reproduction
(Master thesis, 2020-07-01)Declining ice cover in the Arctic has made it possible to extract oil reserves in areas that were once unreachable. However, all oil exploration comes with an inherent risk of spills. Conditions in the Arctic may increase ... -
Spawning season fidelity in spring and autumn spawning Atlantic herring, Clupea harengus. - A comparative study of genomic and phenotypic separation methods
(Master thesis, 2019-06-14)Atlantic herring have a complex population structure and show a wide range of life history strategies, including spawning times and locations. Time of spawning is a key characteristic for population separation. Spawning ... -
Species composition, distribution and ecology of the demersal fish community along the Norwegian coast north of Stad under varying environmental conditions
(Master thesis, 2019-06-14)In the last decades, temperatures of the Atlantic current that enters the Norwegian Coastal Current (NCC) has been above the yearly average, with 2007 as the warmest registration on record (Skagseth 2012). The climatic ... -
Spredning av lakselus (Lepeophtheirus salmonis) fra oppdrettsanlegg og beregnet dødelighet på utvandrende smolt fra Stadt til Hustadvika (PO5)
(Master thesis, 2022-06-01)Lakselusen (Lepeophtheirus salmonis) er en naturlig parasitt i norske fjorden, som har blitt et økende problem for både oppdretts- og villaks. Spesielt i løpet av utvandringsperioden fører økt lusepåslag til utfordringer. ... -
Studenters oppfatning av hva det vil si å være en dyktig biologilærer: En studie av lærerkvaliteter, undervisningstiltak – og metoder som gjør at biologilærere kan betegnes som dyktige undervisere
(Master thesis, 2019-06-25)Studien handler om studenters oppfatning om temaet lærerdyktighet: Hvorfor er det viktig å ha innsyn i hva elever tenker om læreres undervisningspraksis, og hvordan kan denne kunnskapen tas i bruk? Lærerdyktighet i ulike ... -
Studies of granulocyte colony stimulating factor signaling to develop tools for clinical assessments of severe congenital neutropenia
(Master thesis, 2023-06-02)Neutropenia is condition characterized by low number of neutrophils in circulation. This leads to an increased risk of infections and is often diagnosed early in life. Extreme cases are known as severe neutropenia and are ... -
Studies of retinoid X receptors (Rxr) and the Rxr-signaling pathway in Atlantic cod (Gadus morhua) using immunochemical and ex vivo approaches
(Master thesis, 2023-09-04)Nuclear receptors (NRs) comprise a large superfamily of ligand-activated transcription factors. Many NRs facilitate gene expression through heterodimeric binding to retinoid X receptor (RXR). RXR is thus part of a vast ... -
