Ammonia-eliminating potential of Gracilaria sp. And zeolite: a preliminary study of the efficient ammonia eliminator in aquatic environment
(Peer reviewed; Journal article, 2019-02-01)High density and high feeding volume are regarded as factors causing huge accumulations of Total Ammonia Nitrogen (TAN) in an aquaculture system. An uncontrolled TAN concentration in an aquaculture system can pose a threat ... -
An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae
(Journal article; Peer reviewed, 2022)The nuclear pore complex (NPC) is the central portal for macromolecular exchange between the nucleus and cytoplasm. In all eukaryotes, NPCs assemble into an intact nuclear envelope (NE) during interphase, but the process ... -

Anaesthesia of farmed fish with special empasis on atlantic cod (Gadus morhua) and atlantic habibut (Hippoglossus hippoglossus)
(Doctoral thesis, 2011-03-23)During the life cycle as farmed animals there are numerous situations where fish are subjected to handling and confinement. Netting, weighing, sorting, vaccination, transport and, at the end, slaughter are common events ... -
Analyse av biomarkører i leverprøver fra atlanterhavstorsk (Gadus morhua) benyttet i et burforsøk i Kollevåg, Askøy kommune
(Master thesis, 2017-09-05)Kollevåg er et etablert friluftsområde på vestsiden av Askøy i Hordaland. Området har også i tidsperioden 1930-1975 fungert som et avfallsdeponi for usortert avfall for innbyggere i Bergen kommune. Avfallet ble dumpet på ... -
Analyse av flervalgstest som eksamensform på bachelorutdanning i biologi ved UiB
(Master thesis, 2016-06-02)Eksamen i høyere utdanning har tradisjonelt fokusert på kontrollaspektet ved vurdering. I dag er det et økende fokus på læringsaspektet ved vurdering noe som vises i interessen for autentiske og varierte vurderingsformer. ... -
Analyses of bacteriophages to Yersinia ruckeri and the salmon (Salmo salar L.) antibody response to the bacteriophages.
(Master thesis, 2017-06-30)New technologies for producing Atlantic salmon like the recirculation aquaculture systems (RAS) have gained popularity, and has overthrown the traditional flow through systems used in the freshwater stages of the Atlantic ... -
Analyses of Thermotogales secretomes
(Master thesis, 2014-08-04)The aim of this study was to analyse the secretomes of the deeply branching order Thermotogales, using the species of Thermosipho africanus, Petrotoga mobilis, and Kosmotoga olearia, which have all been isolated from hot ... -
Analysing estimators in the alternative echo integrator method
(Peer reviewed; Journal article, 2010)Abstract: New and existing estimators of the “Echo Value Constant” based on split-beam detected and integrated single target echoes in the “alternative echo integration method” have been compared by using acoustic data. ... -
Analysis of coastal cod (Gadus morhua L.) sampled on spawning sites reveals a genetic gradient throughout Norway's coastline
(Peer reviewed; Journal article, 2018-07-09)Background. Atlantic cod (Gadus morhua L.) has formed the basis of many economically significant fisheries in the North Atlantic, and is one of the best studied marine fishes, but a legacy of overexploitation has depleted ... -
Analysis of IgM sub-variants related to ancestral tetraploidy in salmonid fish
(Doctoral thesis, 2013-03-21)Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) possess two paralogous IgM heavy chain (μ) genes related to ancestral tetraploidy. Accordingly, IgM subpopulations of Atlantic salmon and brown trout can be ... -
Analysis of immunoglobulin and T cell receptor gene expression in ballan wrasse (Labrus bergylta) revealed an extraordinarily high IgM expression in the gut
(Peer reviewed; Journal article, 2019)The serum IgM concentration of ballan wrasse is relatively high, estimated to approximately 13 mg/ml in adult wild fish of 800 g. The present study revealed an unusual high abundance of IgM mRNA in the gut of ballan wrasse. ... -
Analysis of reproductive traits reveals complex population dynamics on a small geographical scale in Atlantic herring
(Journal article; Peer reviewed, 2023-02-01)Atlantic herring (Clupea harengus) has a complex population structure and displays a variety of reproductive strategies. Differences in reproductive strategies among herring populations are linked to their time of spawning, ... -
Analysis of sequencing data in environmental genomics. Exploring the diversity of the microbial biosphere
(Doctoral thesis, 2013-04-12)Most life on this planet is microbial and for the last two decades, environmental genomics has contributed to reveal an impressive biodiversity of this microbial life. This approach applies DNA sequencing to environmental ... -
Analysis of transcription factor complexes and their associated chromatin interactions during erythropoiesis
(Doctoral thesis, 2014-01-17)Cis-regulatory elements can control gene transcription over large distances. Studying the association between cis-regulatory elements and the mechanism of gene regulation is important since the disruption in the transcriptional ... -
Annelid functional genomics reveal the origins of bilaterian life cycles
(Journal article; Peer reviewed, 2023)Indirect development with an intermediate larva exists in all major animal lineages1, which makes larvae central to most scenarios of animal evolution2,3,4,5,6,7,8,9,10,11. Yet how larvae evolved remains disputed. Here we ... -
Anorectic role of high dietary leucine in farmed Atlantic salmon (Salmo salar L.): Effects on feed intake, growth, amino acid transporters and appetite-control neuropeptides
(Journal article; Peer reviewed, 2023)Leucine has been identified to modulate feed intake and energy homeostasis in fish as in other vertebrates. Under allostatic conditions, energy expenditure may change, and adjustments to the processes that govern the energy ... -
