    • Antioxidant Activities and Selenogene Transcription in the European Sea Bass (Dicentrarchus labrax) Liver Depend, in a Non-linear Manner, on the Se/Hg Molar Ratio of the Feeds 

      Espino, Marinelle; Eguiraun, Harkaitz; Diaz de Cerio, Oihane; Carrero, José Antonio; Etxebarria, Nestor; Martinez, Iciar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-31)
      Feeding 3.9 and 6.7 mg Hg/kg (Se/Hg molar ratios of 0.8 and 0.4, respectively) for 14 days negatively afected Dicentrarchus labrax growth and total DNTB- and thioredoxin-reductase (TrxR) activities and the transcription of four redox genes (txn1, gpx1, txnrd3, and txnrd2) in the liver, but a diet with 0.5 mg Hg/kg (Se/Hg molar ratio 6.6) slightly increased both reductase activities and the ...

    • Hurtig metode for å estimere buksprenging i pelagisk fisk ombord 

      Slizyte, Rasa; Mozuraityte, Revilija; Martinez, Iciar (Research report; Forskningsrapport, 2013)
      Buksprenging er en kvalitetsforringende prosess hvor bukområdet hos fisken brytes ned post mortem. Denne rapporten oppsummerer arbeidet med utviklingen av en anvendelig hurtigtest for å estimere enzymlekkasje som forårsaker buksprenging i pelagiske fiskearter. Måleutstyret er kommersielt tilgjengelig og krever lite opplæring før bruk. Metoden er brukervennlig og gir en objektiv vurdering av ...

    • Reducing the number of individuals to monitor shoaling fish systems – Application of the Shannon entropy to construct a biological warning system model 

      Eguiraun, Harkaitz; Casquero, Oskar; Sørensen, Asgeir Johan; Martinez, Iciar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-08)
      The present study aims at identifying the lowest number of fish (European seabass) that could be used for monitoring and/or experimental purposes in small-scale fish facilities by quantifying the effect that the number of individuals has on the Shannon entropy (SE) of the trajectory followed by the shoal’s centroid. Two different experiments were performed: (i) one starting with 50 fish and decreasing ...

    • Safe production of farmed Atlantic salmon (Salmo salar) 

      Dahle, Stine Veronica Wiborg; Westavik, Harry; Sandberg, Merete Gisvold; Garforth, Dave; Winkel, Clare; Andree, Sabine; Martinez, Iciar (Research report; Forskningsrapport, 2010-06-17)
      This work contains a review of the undesirable substances that may be introduced as contaminants of natural and malicious origin, and of emerging hazards, in the production chain of farmed salmon,from ova to packed fillet.<p><p> The work, focused in the supply chain to European countries, contains a brief introduction to general food safety in relation to aquaculture products, followed by an ...
