En kartlegging av status for tarmslyng i oppdrettstorsk (Gadus morhua)
Fredriksen, Bendik (Master thesis, 2024)Et tiår etter at forrige «bølge» med torskeoppdrett kollapset, har det igjen oppstått en økende interesse knyttet til oppdrett av torsk i Norge. Dødeligheten hos oppdrettstorsk har generelt vært noe lavere sammenlignet med ... -
Fate of Lepeophtheirus salmonis and Caligus elongatus During Farmed Salmon Crowding
Nersten, Marit (Master thesis, 2021)Økt reproduksjon og spredning av Lepeophtheirus salmonis og Caligus elongatus hindrer videre vekst i oppdrettsnæringen og truer den naturlige bestanden av villaks. Trenging vil si å øke tettheten av fisken og er en viktig ... -
