  • Quantification of bell-shaped size selectivity in shrimp trawl fisheries using square mesh panels and a sorting cone after a Nordmøre grid 

    Sistiaga, Manu Berrondo; Herrmann, Bent; Larsen, Roger B.; Brinkhof, Jesse (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-12)
    Shrimp trawlers in the Barents Sea use a Nordmøre sorting grid ahead of a small-mesh codend to avoid bycatch while catching shrimps efficiently. However, small fish can still pass through the grid to enter the codend, which increases their risk of being retained. In this study, we quantified the selectivity of a standard Nordmøre grid used together with one of two different codend designs, namely a ...
  • Trained Innate Immunity of Fish Is a Viable Approach in Larval Aquaculture 

    Zhang, Zuobing; Chi, Heng; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-25)
    The general understanding has been that only adaptive immunity is capable of immunological memory, but this concept has been challenged in recent years by studies showing that innate immune systems can mount resistance to reinfection—as the innate immune system can adapt its function following an insult. Innate immune training offers an attractive approach in intensive fish larval rearing, especially ...
  • A first fecundity study of the female snow crab Chionoecetes opilio Fabricius, 1788 (Decapoda: Brachyura: Oregoniidae) of the newly established population in the Barents Sea 

    Danielsen, Hanna Ellerine Helle; Hjelset, Ann Merete; Bluhm, Bodil; Hvingel, Carsten; Agnalt, Ann-Lisbeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-11)
    The snow crab <i>Chionoecetes opilio</i> Fabricius, 1788 is a newly established species in the Barents Sea. Since the first individuals were recorded in 1996, the population has increased and a fishery was initiated in 2012. Mature female snow crab caught in the central Barents Sea were investigated with regards to fecundity. Ovigerous females (<i>N</i> = 185) ranged from 48 to 100 mm carapace width ...

  • Genetic changes caused by restocking and hydroelectric dams in demographically bottlenecked brown trout in a transnational subarctic riverine system 

    Klutsch, Cornelya; Maduna, Simo; Polikarpova, Natalia; Forfang, Kristin; Aspholm, Paul Eric; Nyman, Tommi; Eiken, Hans Geir; Amundsen, Per-Arne; Hagen, Snorre (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
    Habitat discontinuity, anthropogenic disturbance, and overharvesting have led to population fragmentation and decline worldwide. Preservation of remaining natural genetic diversity is crucial to avoid continued genetic erosion. Brown trout (<i>Salmo trutta</i> L.) is an ideal model species for studying anthropogenic influences on genetic integrity, as it has experienced significant genetic alterations ...
  • A rapid preparation procedure for laser microdissection‑mediated harvest of plant tissues for gene expression analysis 

    Olsen, Stian; Krause, Kirsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-02)
    <p><i>Background - </i>Gene expression changes that govern essential biological processes can occur at the cell-specific level. To gain insight into such events, laser microdissection is applied to cut out specific cells or tissues from which RNA for gene expression analysis is isolated. However, the preparation of plant tissue sections for laser microdissection and subsequent RNA isolation usually ...

    Previous studies of Eurasian tundra reindeer (<i>Rangifer tarandus tarandus</i>) in Norway indicate that their rumen microbiota play a key role in degrading lichen secondary metabolites. We investigated the presence of usnic acid and atranorin in faecal samples from Svalbard reindeer (<i>R. tarandus platyrhynchus</i>). Samples were collected in Bolterdalen valley together with vegetation samples ...
  • Persistence of environmental DNA in marine systems 

    Collins, Rupert A.; Wangensteen Fuentes, Owen Simon; O'Gorman, Eoin J.; Mariani, Stefano; Sims, David W.; Genner, Martin J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-05)
    As environmental DNA (eDNA) becomes an increasingly valuable resource for marine ecosystem monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a spatio-temporal axis of locally extreme conditions, varying from ocean-influenced offshore to urban-inshore, and between winter and summer. We report that ...

Its distributed character harnesses complementary knowledge, ...
  • Consuming food in pre-industrial Korean travel: approaching from Veblen´s conspicuous consumption 

    Lee, Young-Sook (Peer reviewed; Chapter; Bokkapittel, 2019-02-02)
    The chapter considered Thorstein Veblen’s description of conspicuous consumption in the context of consuming food while travelling. Travelogues from pre-industrial Korean society were used for the data in the chapter, employing critical discourse analysis. The identified meanings were subsequently reflected on Veblen’s conspicuous consumption. Two embedded notions of instrumental and intrinsic values ...
  • Seasonal and ontogenetic variation in the infection of intestinal parasites in Arctic charr (Salvelinus alpinus) and brown trout (Salmo trutta) in a subarctic lake. 

    Prati, Sebastian (Master thesis; Mastergradsoppgave, 2019-05-14)
    The vast majority of studies in northern lake systems have been carried out on a short-term scale, principally during spring and summer and mostly focusing on a single parasite species. There are few winter studies of fish parasites in the subarctic area, and even less regarding seasonal variations in the sub-communities of intestinal parasites in Arctic charr (Salvelinus alpinus) and brown trout ...

    Edwards, Jena E.; Hiltz, Elizabeth; Broell, Franziska; Bushnell, Peter G.; Campana, Steven E.; Christiansen, Jørgen Schou; Devine, Brynn M.; Gallant, Jeffrey J.; Hedges, Kevin J.; MacNeil, M. Aaron; McMeans, Bailey C.; Nielsen, Julius; Præbel, Kim; Skomal, Gregory B.; Steffensen, John Fleng; Walter, Ryan P.; Watanabe, Yuuki Y.; VanderZwaag, David L.; Hussey, Nigel E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-02)
    Long-lived species share life history traits such as slow growth, late maturity, and low fecundity, which lead to slow recovery rates and increase a population’s vulnerability to disturbance. The Greenland shark (Somniosus microcephalus) has recently been recognized as the world’s longest-lived vertebrate, but many questions regarding its biology, physiology, and ecology remain unanswered. Here we ...

    Increased visitation to protected areas could have adverse impacts on the conservation values in the protected areas, and therefore effective visitor monitoring methods are needed to meet the complex management challenges that arise. Collecting data on human impacts is highly time consuming, thus requiring more effective tools that allow for high-quality and long-term measurements. In this study, ...
  • Effect of three different codend designs on the size selectivity of juvenile cod in the Barents Sea shrimp trawl fishery 

    Herrmann, Bent; Sistiaga, Manu Berrondo; Larsen, Roger B.; Brinkhof, Jesse (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-31)
    Shrimp trawlers often use a Nordmøre sorting grid ahead of a small mesh codend to avoid bycatch of juvenile fish while allowing shrimps to be efficiently caught. However, small fish can pass through the grid to enter the codend and risk being retained. The risk of retention for fish of different sizes depends the size selection in the Nordmøre grid and the size selection in the subsequent codend, ...
