      Chang, Chia Jung; Sun, Baojian; Robertsen, Børre (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-09)
      There is a need for more efficient vaccines to combat viral diseases of Atlantic salmon and other farmed fish. DNA vaccines are highly effective against salmonid rhabdoviruses, but have shown less effect against other viruses. In the present work we have studied if type I IFNs might be used as adjuvants in fish DNA vaccines. For this purpose we chose a DNA vaccine model based on the hemagglutin ...
    • Adjuvants and immunostimulants in fish vaccines: Current knowledge and future perspectives. 

      Tafalla, C; Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Vaccination is the most adequate method to control infectious diseases that threaten the aquaculture industry worldwide. Unfortunately, vaccines are usually not able to confer protection on their own; especially those vaccines based on recombinant antigens or inactivated pathogens. Therefore, the use of adjuvants or immunostimulants is often necessary to increase the vaccine efficacy. Traditional ...

    • Aldri mer 18. april! 

      Finstad, Bjørn-Petter; Holm, Petter (Chronicle; Kronikk, 2013-04-18)
      Den 18. april 1989 er et viktig vendepunkt i norsk fiskerihistorie. Det var den dagen Fiskeridepartementet stoppet kystflåtens fiske etter torsk nord for 62. breddegrad - midt i den tradisjonelle sesongen. Reaksjonene lot ikke vente på seg. Historiens første totalforbud mot å fiske torsk var “et sjokk til dyp ettertanke”, het det i Fiskeribladet.
    • Allelic losses and gains during translocations of a high conservation value fish, Coregonus lavaretus 

      Præbel, Kim; Bean, Colin; Dodd, Jennifer A.; Etheridge, Elizabeth C.; Gowans, Andrew R. D.; Knudsen, Rune; Lyle, Alexander A.; Maitland, Peter S.; Winfield, Ian J.; Adams, Colin E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-09)
      <ol type="1"> <li>The use of translocations to establish new or ‘refuge’ populations for species with high conservation value is controversial but widely used in conservation management. One of the risks of this approach is that an establishing population does not adequately capture the genetic diversity of the donor gene pool. This effect, rarely examined, is tested here.</li> <li>In this study ...
    • Allochrony as a potential driver for reproductive isolation in adaptive radiations of European whitefish ecomorphs 

      Bitz-Thorsen, Julie; Häkli, Katja; Bhat, Shripathi; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
      In northern Fennoscandian lakes, monophylogenetic lineages of postglacial fishes are radiating into several adaptive forms, but the speciation process is still at an incipient stage. The speciation process has received increased attention over the years, but the underlying mechanisms and drivers are still debated and poorly understood. European whitefish (<i>Coregonus lavaretus</i> [L.]) is the most ...
