Microbiological aspects of fish handling and processing in the Norwegian pelagic sector
(Doctoral thesis, 2015-03-17)Most global marine fish resources seem to have reached their limit of sustainable exploitation, whereas the demand for high quality fish products is still increasing. The fish sector needs to comply with the growing market ... -
Microbiological assessment along the fish production chain of the Norwegian pelagic fisheries sector - Results from a spot sampling programme
(Peer reviewed; Journal article, 2015-10)Microbes play an important role in the degradation of fish products, thus better knowledge of the microbiological conditions throughout the fish production chain may help to optimise product quality and resource utilisation. ... -
The Microbiome and Occurrence of Methanotrophy in Carnivorous Sponges
(Peer reviewed; Journal article, 2016-11-09)As shown by recent studies, filter-feeding sponges are known to host a wide variety of microorganisms. However, the microbial community of the non-filtering carnivorous sponges (Porifera, Cladorhizidae) has been the subject ... -
Microbiome dataset from a marine recirculating aquaculture system (RAS) for salmon post-smolt production in Norway
(Journal article; Peer reviewed, 2022)A marine aquaculture recycling system (RAS) for the production of post-smolt was monitored for microbial community structures during the first year of operation. Sample material was obtained monthly from the biofilter ... -
Microbiomes of Hadal Fishes across Trench Habitats Contain Similar Taxa and Known Piezophiles
(Journal article; Peer reviewed, 2022)Hadal snailfishes are the deepest-living fishes in the ocean, inhabiting trenches from depths of ∼6,000 to 8,000 m. While the microbial communities in trench environments have begun to be characterized, the microbes ... -
Micromonas versus virus: New experimental insights challenge viral impact
(Peer reviewed; Journal article, 2017-05)Viruses have recurrently been hypothesized as instrumental in driving microbial population diversity. Nonetheless, viral mediated co-existence of r/kstrategists, predicted in the Killing-the-Winner (KtW) hypothesis, remains ... -
Micronekton biomass distribution, improved estimates across four north Atlantic basins
(Peer reviewed; Journal article, 2019)Distribution of micronekton was investigated during early summer of 2013, using data from a cruise covering the central parts of four north Atlantic basins, the Norwegian Sea (NS), Iceland Sea (ICS), Irminger Sea (IRS), ... -
Microplastic variability in subsurface water from the Arctic to Antarctica
(Journal article; Peer reviewed, 2022)Comparative investigations of microplastic (MP) occurrence in the global ocean are often hampered by the application of different methods. In this study, the same sampling and analytical approach was applied during five ... -
Microplastics in arctic invertebrates- Status on occurrence and recommendations for future monitoring
(Journal article; Peer reviewed, 2022)Few studies have been published on occurrence and distribution on microplastics (MPs) in invertebrates from the Arctic. We still need to develop harmonised methods to enable good comparison between studies taking into ... -
Microrefugia and shifts of Hippophae tibetana (Elaeagnaceae) on the north side of Mt. Qomolangma (Mt. Everest) during the last 25000 years
(Peer reviewed; Journal article, 2014-05-19)Microrefugia at high altitudes or high latitudes are thought to play an important role in the post-glacial colonization of species. However, how populations in such microrefugia have responded to climate changes in alternating ... -
Microsomal triglyceride transfer protein in the ectoparasitic crustacean salmon louse (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2017-08)The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish. Salmon lice produce high numbers of offspring, necessitating ... -
Migration of Atlantic salmon post-smolts in a fjord with high infestation pressure of salmon lice
(Peer reviewed; Journal article, 2018)Understanding Atlantic salmon Salmo salar post-smolt coastal migration behaviour is crucial for predicting their exposure to ecological challenges such as the parasite salmon louse Lepeophtheirus salmonis. We compared the ... -
Miljø-DNA påvisning av Pasteurella atlantica gv. salmonicida
(Master thesis, 2022-05-16)Pasteurellose forårsaket av Pasteurella atlantica gv. salmonicida hos atlantisk laks (Salmo salar L.) har de siste årene etablert seg som en bakteriesykdom som truer fiskevelferd og bærekraftig produksjon i den norske ... -
Miljøundersøking av Tveitevatnet og Fjøsangervassdraget i Bergen, med fokus på abbor (Perca fluviatilis) som indikatororganisme
(Master thesis, 2015-01-28)Tveitevatnet (Årstad bydel, Bergen kommune) har lenge vore påverka av forureina sigevatn fra eit gammalt deponi på Slettebakken i tillegg til industri i næromradet, noko som har gjort at miljøgifter som PCB og tungmetall ... -
Mining Lepeophtheirus salmonis RNA-Seq data for qPCR reference genes and their application in Caligus elongatus
(Journal article; Peer reviewed, 2023)Lepeophtheirus salmonis and Caligus elongatus are two parasitic copepod species posing a significant threat to salmonid aquaculture. Consequently, several gene expression studies are executed each year to gain new knowledge ... -
The Miocene: The Future of the Past
(Journal article; Peer reviewed, 2021)The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and fauna evolved into the ... -
Mitigation of oxygen decline in fjords by freshwater injection
(Journal article; Peer reviewed, 2023)The exchange of water masses between deep fjords and the open ocean is commonly constrained by a topographical barrier called the sill. While fjord water above the sill depth communicates relatively freely with the open ... -
Mitochondrial aquaporin-8-mediated hydrogen peroxide transport is essential for teleost spermatozoon motility
(Peer reviewed; Journal article, 2015-01-14)Reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2), cause oxidative cell damage and inhibit sperm function. In most oviparous fishes that spawn in seawater (SW), spermatozoa may be exposed to harmful ROS ... -
