    Pinar-Méndez, Anna; Wangensteen, Owen S.; Præbel, Kim; Galofré, Belén; Méndez, Javier; Blanch, Anicet R.; García-Aljaro, Cristina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-30)
    Monitoring bacterial communities in a drinking water treatment plant (DWTP) may help to understand their regular operations. Bacterial community dynamics in an advanced full-scale DWTP were analyzed by 16S rRNA metabarcoding, and microbial water quality indicators were determined at nine different stages of potabilization: river water and groundwater intake, decantation, sand filtration, ozonization, ...
  • Population cycles in small rodents seen through the lens of a wildlife camera 

    Kleiven, Eivind Flittie (Doctoral thesis; Doktorgradsavhandling, 2022-06-08)
    Population cycles in small rodents have attracted attention from ecologists for more than a century. This spectacular phenomenon is crucial for the functioning of many northern food-webs and has intrigued ecologist because of its lessons for general ecology. Knowledge about the rodent cycle has, however, been hampered by the lack of reliable monitoring methods both for rodents and some of their ...
  • For all audiences: Incorporating immature stages into standardised spider inventories has a major impact on the assessment of biodiversity patterns 

    Domènech, Marc; Wangensteen, Owen S.; Enguídanos, Alba; Malumbres-Olarte, Jagoba; Arnedo, Miquel A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-25)
    Although arthropods are the largest component of animal diversity, they are traditionally underrepresented in biological inventories and monitoring programmes. However, no biodiversity assessment can be considered informative without including them. Arthropod immature stages are often discarded during sorting, despite frequently representing more than half of the collected individuals. To date, ...
  • Kiselalger som fôrkomponent i laksefôr. Biokjemisk sammensetning og fettsyreprofil hos atlantisk laks (Salmo salar L.) fôret med ulike lipid- og proteinkilder 

    Heimland, Maria (Master thesis; Mastergradsoppgave, 2020-05-15)
    Det økende behovet for marine ressurser som ingrediens i fôr har ført til et søk etter nye ressurser, da dagens ressurser ikke lengre er bærekraftig. For å øke utbytte er det foreslått å rette søket lengre ned i næringskjeden. Marine kiselalger er et eksempel på slike organismer. Disse er ikke godt utnyttet i dag, hovedsakelig på grunn av manglende kunnskap rundt teknologi, samt forskning på hvilke ...

    Isaksen, Anja (Master thesis; Mastergradsoppgave, 2022-03-01)
    Formålet med denne studien var å avdekke kundeopplevelser gjennom en bankbytteprosess, som en studie av kundereisen fra gammel til ny bank. I henhold til det teoretiske rammeverket for kundereiser, ble bankbytteprosessen delt opp i tre faser, før, under og etter bankbytte. Videre ble bankkunders opplevelser knyttet til hver fase undersøkt. Opplevelse er i denne sammenheng definert som en helhetlig ...
  • Ufordøyelig binder i fôr til laks - evaluering av velferd og tilvekst 

    Tronsen, Kristina Finden (Master thesis; Mastergradsoppgave, 2021-05-18)
    Med stadig økning i produksjon av oppdrettslaks og et relativt lavt antall tilgjengelig vannkilder til smoltproduksjon, ser man økt bygging av RAS-anlegg. Ved rensing av produksjonsvannet er første vannbehandlingstrinn mekanisk filtrering etterfulgt av biofiltrering, rensesystemets flaskehals. Biofilteret renser vannet for nitrogenholdige molekyler (TAN), som er giftig for laks, og er sensitivt for ...
  • The distribution of Eubothrium crassum (Cestoda: Pseudophyllidea) in brown trout, Salmo trutta, in allopatric and sympatric populations 

    Hofstad Lian, Anne (Master thesis; Mastergradsoppgave, 2021-05-17)
    Sticklebacks in particular have been suspected to have a role in transmission of E. crassum to its final host, the brown trout. In this study, prevalence and mean abundance of E. crassum in trout have been examined in allopatric and sympatric populations to address the suspected role of sticklebacks in the life cycle of E. crassum. 1106 trout from 22 lakes in the northern parts of Norway were ...
  • Ordningen med utviklingstillatelser Et bidrag til innovasjon i norsk oppdrettsnæring 

    Bekkeli, Karl Erik (Master thesis; Mastergradsoppgave, 2017-05-15)
    Norsk oppdrettsnæring har opplevd eventyrlig vekst. I løpet av en et halvt århundre har næringen utviklet seg fra omtrent ingenting til å bli blant våre viktigste og største eksportnæringer. Veksten har i stor grad skyltes oppdretternes kontinuerlige produktivitetsforbedringer, basert på forbedring av utstyr, avl og utvikling av vaksiner og fôr. Skal eventyret få fortsette er næringen avhengig av å ...

    Bertheussen, Bernt Arne; Bendiksen, Bjørn Inge (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-09)
    Norge er verdens nest største eksportør av sjømat. Inntektene skaper arbeid og aktivitet i lokalsamfunn langs hele kysten. Denne studien undersøker hvor sårbare inntektene til sjømatnæringen har vært under Covid-19 pandemien som har preget mesteparten av 2020 og hele 2021. I tillegg til å analysere inntektsutviklingen på aggregert nivå for fiskeri og havbruk, presenterer studien sektorvise analyser ...
  • Vi trenger flere sjømat-influensere! 

    Alm, Siril (Chronicle; Kronikk, 2022-04-29)
    Til tross for at folk er blitt mer opptatt av å ha et sunt kosthold, har sjømatkonsumet vært dalende i flere år – spesielt blant den unge befolkningen. Kan sosiale medier og influensere være løsningen på problemet?
  • The future of Arctic sea-ice biogeochemistry and ice-associated ecosystems 

    Lannuzel, Delphine; Tedesco, Letizia; Leeuwe, Maria van; Campbell, Karley; Flores, Hauke; Delille, Bruno; Miller, Lisa; Stefels, Jacqueline; Assmy, Philipp; Bowman, Jeff; Brown, Kristina; Castellani, Giulia; Chierici, Melissa; Crabeck, Odile; Damm, Ellen; Else, Brent; Fransson, Agneta; Fripiat, Francois; Geilfus, Nicolas-Xavier; Jacques, Caroline; Jones, Elizabeth; Kaartokallio, Hermanni; kotovitch, marie; Meiners, Klaus M.; Moreau, Sebastien; Nomura, Daiki; Peeken, Ilka; Rintala, Janne-Markus; Steiner, Nadja; Tison, Jean-Louis; Vancoppenolle, Martin; Linden, Fanny Van der; Vichi, Marcello; Wongpan, Pat (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-27)
    The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate earlier seasonal primary production. This earlier growing season may be accompanied by an increase in ice algae and phytoplankton biomass, augmenting the emission of dimethylsulfide and capture of carbon dioxide. Secondary production may also increase on the shelves, although the loss of sea ice exacerbates ...
  • Antimikrobielle forbindelser i kongsnegl (Buccinum undatum) og neptunsnegl (Neptunea despecta) 

    Martinsen, Lindsey Leigh Beecher (Master thesis; Mastergradsoppgave, 2017-05-15)
    Det økende antall patogene bakteriestammer som utvikler resistens mot dagens kommersielle antibiotika er en av de største truslene mot den globale helsen i vår tid. Infeksjonssykdommer som tidligere kunne behandles med antibiotika har nå nesten blitt umulige å behandle, det er derfor et umiddelbart behov for nye typer antibiotika med nye virkningsmekanismer enn det som allerede eksisterer på markedet. ...

    Benjaminsen, Stine Charlotte; Bourgeon, Sophie; Herzke, Dorte; Ask, Amalie; Collard, France; Gabrielsen, Geir Wing (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-20)
    Arctic wildlife is facing multiple stressors, including increasing plastic pollution. Seabirds are intrinsic to marine ecosystems, but most seabird populations are declining. We lack knowledge on plastic ingestion in many arctic seabird species, and there is an urgent need for more information to enable risk assessment and monitoring. Our study aimed to investigate the occurrence of plastics in ...
  • Oceanic plastic pollution caused by Danish seine fishing in Norway 

    Syversen, Tore; Lilleng, Grethe; Vollstad, Jørgen; Bård, Hanssen; Sønvisen, Signe Annie (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-06)
    Wear and tear on fishing gear is a sparsely investigated source of microplastic pollution in the sea. In Norway, Danish seine ropes and trawls are the fishing gears that contribute most to this pollution. The main reason for this pollution is that the seine ropes are dragged along the seabed over a considerable distance, creating a friction force that results in high ropes wear. This note reports ...
  • Arctic marine fishes and their fisheries in light of global change 

    Christiansen, Jørgen Schou; Mecklenburg, Catherine W.; Karamushko, Oleg V. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-09-17)
    In light of ocean warming and loss of Arctic sea ice, harvested marine fishes of boreal origin (and their fisheries) move poleward into yet unexploited parts of the Arctic seas. Industrial fisheries, already in place on many Arctic shelves, will radically affect the local fish species as they turn up as unprecedented bycatch. Arctic marine fishes are indispensable to ecosystem structuring and ...
  • Ultrastructural evidence for the participation of muscle cells in the formation of extracellular matrices in aporocotylid blood flukes (Digenea) 

    Poddubnaya, Larisa G.; Zhokhov, Alexander E.; Hemmingsen, Willy; Gibson, David I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-05)
    The muscle cells and extracellular matrices (ECMs) of two teleost-infecting blood flukes belonging to distinct evolutionary lineages of the Aporocotylidae (Digenea) were examined using Transmission Electron Microscopy. Four morphotypes of muscle cells were found in the freshwater species Sanguinicola sp., but were considered to be various developmental stages of a single cisternic type. In the marine ...
