Identification of in vivo induced antigens of the malacosporean parasite Tetracapsuloides bryosalmonae (Cnidaria) using in vivo induced antigen technology
(Journal article; Peer reviewed, 2022)Tetracapsuloides bryosalmonae is a malacosporean endoparasite that causes proliferative kidney disease (PKD) in wild and farmed salmonids in Europe and North America. The life cycle of T. bryosalmonae completes between ... -
Identification of key components in the energy metabolism of Archaeoglobus fulgidus by transcriptome analyses
(Peer reviewed; Journal article, 2014-03-11)Energy conservation via the pathway of dissimilatory sulfate reduction is present in a diverse group of prokaryotes, but is most comprehensively studied in Deltaproteobacteria. In this study, whole-genome microarray analyses ... -
Identifying the driving factors behind observed elevational range shifts on European mountains
(Peer reviewed; Journal article, 2014-04-13)Aim In recent decades species ranges have shifted upwards in elevation and northwards in latitude. These shifts are commonly interpreted as a response to recent climate warming. However, several alternative hypotheses have ... -
IgE sensitization to the fish parasite Anisakis simplex in Norway
(Doctoral thesis, 2015-05-11)Anisakis simplex is a fish parasite which infects many commercially important fish species worldwide. When ingested in contaminated raw or poorly prepared seafood, this parasite may lead to infection and/or allergic reaction ... -
Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar
(Peer reviewed; Journal article, 2015-02)There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains , and , respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, ... -
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 ... -
Immunrespons mot Pasteurella spp. hjå rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.)
(Master thesis, 2021-06-01)Dei siste åra har ein sett ei dramatisk auke i tilfelle pasteurellose i norsk oppdrett av rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.). Sjukdommen førar til redusert fiskevelferd og kan innebere høg ... -
The impact of anti-sea lice pesticides, azamethiphos and deltamethrin, on European lobster (Homarus gammarus) larvae in the Norwegian marine environment
(Journal article; Peer reviewed, 2020)Anti-sea lice pesticides, used in the salmonid aquaculture industry, are a growing environmental concern due to their potential to adversely affect non-target crustaceans. Azamethiphos and deltamethrin are two bath treatment ... -
Impact of Antioxidant Feed and Growth Manipulation on the Redox Regulation of Atlantic Salmon Smolts
(Journal article; Peer reviewed, 2022-08-30)Accumulating evidence indicates a close relationship between oxidative stress and growth rate in fish. However, the underlying mechanisms of this relationship remain unclear. This study evaluated the combined effect of ... -
Impact of cysteine 106 oxidation on function and localisation of the Parkinson’s disease-related protein DJ-1

Impact of dietary level and ratio of n-6 and n-3 fatty acids on disease progression and mRNA expression of immune and inflammatory markers in Atlantic salmon (Salmo salar) challenged with Paramoeba perurans
(Journal article; Peer reviewed, 2021)The aim of the study was to investigate the influence of dietary level and ratio of n-6/n-3 fatty acids (FA) on growth, disease progression and expression of immune and inflammatory markers in Atlantic salmon (Salmo salar) ... -
Impact of environmental factors on the growth and maturation of farmed Arctic charr
(Journal article; Peer reviewed, 2020)Farming of Arctic charr mainly takes place in land‐based farms applying intensive rearing methods with relatively high production costs. Depending on local conditions at each site, it is possible to regulate important ... -
Impact of environmental parameters and dispersal on microbial communities in hydrothermal areas of the Nordic Seas
(Doctoral thesis, 2017-09-29)The oceans are an extremely diverse environment due to the numerous physicochemical gradients occurring throughout the water column. Microorganisms have adapted to live in virtually all available niches. Therefore, an ... -
Impact of fish density and specific water flow on skin properties in Atlantic salmon (Salmo salar L.) post-smolts
(Peer reviewed; Journal article, 2016)Prolonged production of Atlantic salmon (Salmo salar) post-smolts in closed-containment systems has prompted research into biological requirements under higher production intensities. This study examined the effect of fish ... -

(Peer reviewed; Journal article, 2016-02)Growth and survival of Maurolicus muelleri larvae in Herdlefjorden, Norway, were investigated by daily otolith increment analysis. While high egg densities were generally observed throughout the spawning season, three ... -
Impact of long-term fasting on the stomach-hypothalamus appetite regulating genes in Atlantic salmon postsmolts
(Journal article; Peer reviewed, 2023)Atlantic salmon will experience periods of fasting during its lifecycle. In nature, prolonged fasting periods occur owing to seasonal fluctuations in available feeds, migration or in relation to reproduction. In a culture ... -
