    • Determination of pH in pre rigor fish muscle - method matters 

      Skjold, Vetle; Joensen, Joan Karl; Esaiassen, Margrethe; Olsen, Ragnar Ludvig (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-06)
      The determination of post mortem muscle pH are often carried out in studies on how pre-slaughter handling influences the development of rigor mortis and the quality of the fish products. The analysis might be performed by inserting a pH-electrode into the intact flesh or using a suspension containing a minced muscle sample. Although it has been known for a long time that mincing muscle tissue ...

    • Gradually decreasing daylength after smoltification induced by “winter signal“ reduced sexual maturation in male Atlantic salmon 

      Skjold, Vetle; Rørvik, Kjell-Arne; Sveen, Lene; Burgerhout, Erik; Mota, Vasco C.; Weihe, Runi; Ytrestøyl, Trine; Bou, Marta; Jacobsen, Hans Jakup; Allaoui, Giovanni; Fuskevåg, Ole-Martin; Dessen, Jens-Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-16)
      Introduction: Maturation in seawater-adapted (smoltified) male Atlantic salmon is undesirable yet frequently reported in fish weighing up to 1 kg reared under intensive conditions in land-based facilities. Although the photoperiod regulates both smoltification and maturation, the optimal post-smoltification regimen for the prevention of maturation is unclear.<p> <p>Methods: In this study, ...

    • Måling av pH i pre-rigor fiskemuskel. En analytisk utfordring 

      Skjold, Vetle (Master thesis; Mastergradsoppgave, 2017-11-14)
      I post mortem fiskemuskel kan måling av muskel-pH benyttes som en enkel metode for å vurdere både slakteprosedyre og kvaliteten på muskelkjøttet. Dette ettersom pH kan påvirke egenskaper som filetspalting, tekstur, fasthet, drypptap og farge. I de fleste studier er muskel-pH enten bestemt ved å måle direkte i intakt muskel med stikkelektrode, alternativet er å homogenisere muskel i en vannbasert ...
