H2O2 effects on the potential macroalgal culture species Palmaria palmata (Linnaeus) Weber & Mohr and Ulva lactuca (Linnaeus)
(Master thesis, 2019-06-26)Hydrogen peroxide (H2O2) has been the most used remedy against salmon sea lice (Lepeophtheirus salmonis) in Norway since 2013. This remedy has been considered environmentally friendly, because it breaks down to water and ... -
Happy hatchday! How does timing of hatching affect the survival of larval Gadus morhua in a changing environment?
(Master thesis, 2019-06-22)The classical match-mismatch hypothesis proposes that the timing between larval first feeding and food availability is an important driver of year-class strength. With climate change and the warming of the oceans, it is ... -
How will thawing permafrost affect the microbial abundance and diversity in the Arctic?
(Master thesis, 2020-07-09)Permafrost, permanently frozen soil, constitutes a major portion of the Earth’s terrestrial cryosphere and represents a unique niche for cold-adapted microorganisms. As the global temperature increases, it is still unknown ... -
Immunologiske responsar i huda hos sjøaure (Salmo trutta) ved infeksjon av lakselus (Lepeophtheirus salmonis) i preadulte stadiet
(Master thesis, 2022-06-01)Sjøaure er den anadrome delen av bestanden til brunaure (Salmo trutta). Arten gyter i elvar og bekkar før den smoltifiserer og vandrar ut i kystvatn for å finne større tilgang til føde og dermed vokse seg større. I kystvatn ... -
Immunrespons hos atlantisk laks (Salmo salar) ved infestasjon av lakselus (Lepeophtheirus salmonis): Endringer i genuttrykk og histologiske forandringer i hud
(Master thesis, 2021-06-01)Sammendrag Lakselus blir ansett som den største utfordringen knyttet til oppdrett i dag. Disse utfordningene kommer i form av redusert fiskehelse, økte produksjonskostnader samt tiltak og lovverk som begrenser vekst for ... -

Infection dynamics of marine Eubothrium sp. (Cestoda) in farmed Atlantic salmon
(Master thesis, 2019-06-21)Infections with marine tapeworms have been reported as an increasing problem in aquaculture of Atlantic salmon (Salmo salar L.) in Norway over the last few years. These are caused by the cestode Eubothrium sp. Little is ... -
Influence of temperature and feeding on early sexual maturation commitment in male Atlantic salmon (Salmo salar, L.) during the freshwater stage
(Master thesis, 2021-01-20)The intensification of Atlantic salmon (Salmo salar) post-smolt production to enhance growth performance has promoted a rise in precocious male maturation rates. Unlike traditional parr maturation, which seems to be highly ... -
Integrated taxonomic revision of Afrotropical Xyleborinus reveals an extraordinary recent radiation on Madagascar
(Master thesis, 2020-06-26)Collection efforts on Madagascar have previously revealed a high species diversity in the Scolytinae genus Xyleborinus Reitter, 1913 compared with the African mainland. This study has produced a well supported phylogeny ... -
Interaksjoner mellom marine næringsstoffer og dioksiner hos mus med human AhR
(Master thesis, 2021-11-22)Dioksiner og dioksinlignende PCB er en gruppe kjemiske forbindelser dannet via industrielle prosesser, som grunnet høy persistens vil akkumulere i fettvev hos mennesker og dyr. Fet fisk regnes som den største kilden til ... -
Interpreting the polychromatic variation of the European nudibranch Polycera quadrilineata (O. F. Müller, 1776), with the description of a new species
(Master thesis, 2019-11)The polychromatic variability exhibited by the dorid nudibranch species Polycera quadrilineata (O. F. Müller, 1776) (Family Polyceridae) has long fascinated marine scientists. The species was originally described from the ... -
