Bacterial impact on growth, health and disease of farmed Atlantic salmon and lumpfish
(PhD Thesis;Thesis number 2021:4, Doctoral thesis, 2021)Despite considerable efforts to improve production with regard to animal welfare, disease control and sustainability in Norwegian aquaculture, both losses and feed conversion rate have not declined during the last 10 years. ... -
Choline is an essential nutrient for post-smolt Atlantic salmon (Salmo salar L)
(PhD Thesis;2020:27, Doctoral thesis, 2020)The aquaculture feed industry continuously works to decrease the share of marine ingredients in the diets by searching for alternative feed ingredients. The increased use of such ingredients, on one hand expose the fish ... -
Detection of antibodies in Atlantic salmon using a bead-based multiplexed immunoassay
(PhD Thesis;2020:01, Doctoral thesis, 2020)Viral diseases are among of the main challenges in aquaculture in Norway today. Heart- and skeletal muscle inflammation, caused by Piscine orthoreovirus (PRV), and pancreas disease (PD), caused by Salmonid alphavirus (SAV), ... -
Gut health and microbiota during the life cycle of Atlantic salmon (Salmo salar) produced under commercial Arctic conditions : modulation by functional feed ingredients investigated in vivo and in vitro
(PhD Thesis;2021:17, Doctoral thesis, 2021)The goal of this thesis was to fill some of the knowledge gaps regarding gut health and microbiota of Atlantic salmon in the life period from late freshwater to seawater in the Arctic region for which two strategies were ... -
Immune responses in Atlantic salmon (Salmo salar) following vaccination and Salmonid alphavirus challenge
(Doctoral thesis, 2021)Norway has perfect conditions for Atlantic salmon (Salmo salar) production and is one of the largest producers of salmon for food consumption worldwide, but rearing fish at high densities also means that infectious disease ... -
Immunological and physiological effects of Piscine orthoreovirus infection in Atlantic salmon (Salmo salar)
(PhD Thesis;2017:33, Doctoral thesis, 2017)Heart and skeletal muscle inflammation (HSMI) is an important viral disease in Norwegian farmed Atlantic salmon (Salmo salar), and was associated with Piscine orthoreovirus (PRV) in 2010. Recently, the causality between ... -
Insect larvae meal as a feed ingredient for Atlantic salmon (Salmo salar) : effects on intestinal function, health, and microbiota
(PhD thesis;2021:75, Doctoral thesis, 2021)Being part of fish’s natural diets, insects have become a realistic, sustainable feed ingredient for aquaculture. While insects’ nutritional values have been extensively studied in numerous fish species, their impact on ... -
Lipid and choline supply affect Atlantic salmon enterocyte steatosis : in vivo and in vitro studies
(PhD thesis;2024:10, Doctoral thesis, 2024)The shift of farmed Atlantic salmon from a marine- to plant-based diet the last decades has revealed challenges concerning the dietary requirements necessary to ensure fish health. Of the nutrients lacking in plant feeds, ... -
Melanised focal changes in Atlantic salmon : interactions between infection and immunity
(PhD Thesis;2021:82, Doctoral thesis, 2022)Atlantic salmon (Salmo salar) farming has increased rapidly in Norway over the last 50 years. However, the large-scale farming of salmon battles serious health problems. There are currently many adverse conditions threatening ... -
Molecular characterization of Piscine orthoreovirus (PRV) and its pathogenesis in salmonids
(PhD Thesis;2019:79, Doctoral thesis, 2019)Piscine orthoreovirus (PRV) is a virus of salmonid fish. PRV has been associated with different diseases in various salmonid fish species, including heart and skeletal muscle inflammation (HSMI) in Atlantic salmon and more ... -
Neuroendocrine regulation of pituitary gonadotropins during puberty in Atlantic salmon parr with focus on melatonin and Gnrh systems
(PhD Thesis;2018:105, Doctoral thesis, 2018)The pituitary gland, gonadotropins, together with neurohormones like gonadotropin-releasing hormone (Gnrh) and melatonin are key players in the control of vertebrate reproduction. In teleosts, despite the numerous studies ... -
