The impact of phage treatment on bacterial community structure is minor compared to antibiotics
Gundersen, Madeleine S.; Fiedler, Alexander Willi; Bakke, Ingrid; Vadstein, Olav (Peer reviewed; Journal article, 2023)Phage treatment is suggested as an alternative to antibiotics; however, there is limited knowledge of how phage treatment impacts resident bacterial community structure. When phages induce bacterial lysis, resources become ... -
Influence of Genetic Background and Environmental Factors on the Skin and Gut Microbiota of Atlantic salmon (Salmo salar) Fry

K-selection as microbial community management strategy: A method for improved viability of larvae in aquaculture
Vadstein, Olav; Attramadal, Kari; Bakke, Ingrid; Olsen, Yngvar (Journal article; Peer reviewed, 2018)Aquaculture has the potential to become a major food supplier in a world with an increasing human population, and increased consumption of fish will likely have positive health implications. For marine aquaculture, the ... -
Karakterisering av mikrobiota i vill torsk (Gadus morhua)
Bjørkhaug, Benedicte (Master thesis, 2012)Det har i senere tid vært en økende interesse for GI-mikrobiota i fisk, men det er fremdeles begrenset kunnskap om mikrobiotaens sammensetning og funksjon i tarmen hos vill fisk. Målet med dette prosjektet var å karakterisere ... -
Long-term microbial community structures and dynamics in a commercial RAS during seven production batches of Atlantic salmon fry (Salmo salar)

However, the microbial communities in commercial RAS are highly complex and more knowledge is needed to potentially ... -
Managing the microbial community of marine fish larvae: a holistic perspective for larviculture
Vadstein, Olav; Attramadal, Kari; Bakke, Ingrid; Forberg, Torunn; Olsen, Yngvar; Verdegem, Marc; Giatsis, C.; Skjermo, Jorunn; Aasen, Inga Marie; Gatesoupe, Francois-Joel; Dirckens, Kristof; Sorgeloos, Patrick; Bossier, Peter (Journal article; Peer reviewed, 2018)The availability of high-quality juveniles is a bottleneck in the farming of many marine fish species. Detrimental larvae-microbe interactions are a main reason for poor viability and quality in larval rearing. In this ... -
Mapping bacterial community structures in skin and gill mucus of Atlantic salmon (Salmo salar) smolt from four commercial RAS facilities
