(Peer reviewed; Journal article, 2018-05)Heart and skeletal muscle inflammation (HSMI) caused by piscine orthoreovirus (PRV) and pancreas disease (PD) caused by salmonid alphavirus (SAV) are among the most prevalent viral diseases of Atlantic salmon farmed in ... -
Probing of mortality rate by staying alive: The growth-reproduction trade-off in a spatially heterogeneous environment
(Peer reviewed; Journal article, 2019)1. In many annual plants, mollusks, crustaceans and ectothermic vertebrates, growth accompanies reproduction. The growth curves of these organisms often exhibit a complex shape, with episodic cessations or accelerations ... -
Production and verification of the first Atlantic salmon (Salmo salar L.) clonal lines
(Journal article; Peer reviewed, 2020)Background In several fish species homozygous and heterozygous clonal lines have been produced using gynogenetic and androgenetic techniques. These lines are standardized and can be reproduced over generations. In rainbow ... -
Production performance of Atlantic salmon post-smolts in cyclic hypoxia, and following compensatory growth
(Peer reviewed; Journal article, 2014-07)This study investigated the production performance of the Atlantic salmon postsmolt (Salmo salar L.) subjected to cyclic oxygen reductions (hypoxia) of varying severity. Triplicate groups (N = 955) were kept at constant ... -
Production, characterization, and application of an alginate lyase, AMOR_PL7A, from hot vents in the Arctic mid-ocean ridge
(Journal article; Peer reviewed, 2019)Enzymatic depolymerization of seaweed polysaccharides is gaining interest for the production of functional oligosaccharides and fermentable sugars. We describe a thermostable alginate lyase belonging to Polysaccharide Lyase ... -
Produksjon av antiserum mot Norwegian salmonid alphavirus
(Master thesis, 2012-10-26)Pankreassykdom (PD) er en infeksiøs virussykdom som rammer Atlantisk laks (Salmo salar L.) og regnbueørret (Oncorhynchus mykiss, Walbaum) i både saltvann og ferskvann i flere viktige lakseproduserende land. I studiet vårt ... -
Profundibacter amoris gen. nov., sp. nov., a new member of the Roseobacter clade isolated from Loki's Castle Vent Field on the Arctic Mid-Ocean Ridge
(Peer reviewed; Journal article, 2019)A bacterial strain, designated BAR1T, was isolated from a microbial mat growing on the surface of a barite chimney at the Loki’s Castle Vent Field, at a depth of 2216 m. Cells of strain BAR1T were rod-shaped, Gram-reacti ... -
Progressive Motor and Non-Motor Symptoms in Park7 Knockout Zebrafish
(Journal article; Peer reviewed, 2023)DJ-1 is a redox sensitive protein with a wide range of functions related to oxidative stress protection. Mutations in the park7 gene, which codes for DJ-1 are associated with early onset familial Parkinson’s disease and ... -
The proinflammatory cytokines TNF-α and IL-6 in lumpfish (Cyclopterus lumpus L.) -identification, molecular characterization, phylogeny and gene expression analyses
(Journal article; Peer reviewed, 2020)The proinflammatory cytokines TNF-α and IL-6 are important mediators of inflammatory reactions and orchestrators of the immune system in vertebrate. In this study, we have identified TNF-α and IL-6 in lumpfish, molecular ... -
Proof of Principle Efficacy and Safety Optimisation of Tenacibaculum Vaccine Prototypes Against Tenacibaculosis in Atlantic Salmon
(Master thesis, 2022-06-01)Mouthrot, caused by the bacterium Tenacibaculum maritimum, is a major health and welfare problem in newly sea-transferred Atlantic salmon smolts (Salmo salar) in BC, Canada, and have caused large economical losses over the ... -
Propensity for risk in reproductive strategy affects susceptibility to anthropogenic disturbance
(Journal article; Peer reviewed, 2020)Animals initiate, interrupt, or invest resources in reproduction in light of their physiology and the environment. The energetic risks entailed in an individual’s reproductive strategy can influence the ability to cope ... -
