      Overvåknings- og kartleggingsprogrammet for fiskefôr utføres på vegne av Mattilsynet. I 2022 fikk Havforskningsinstituttet tilsendt 80 fiskefôr, 13 fiskemel, 2 fiskeproteinkonsentrat, 15 vegetabilske mel, 3 insektmel, 10 ...
    • Recommendations for dietary level of micro-minerals and vitamin D3 to Atlantic salmon (Salmo salar) parr and post-smolt when fed low fish meal diets 

      Antony Jesu Prabhu, Antony Jesu Prabhu; Lock, Erik-Jan; Hemre, Gro Ingunn; Hamre, Kristin; Espe, Marit; Olsvik, Pål Asgeir; Silva, Joana; Hansen, Ann-Cecilie; Johansen, Johan; Sissener, Nini; Waagbø, Rune (Journal article; Peer reviewed, 2019)
      Atlantic salmon (Salmo salar) feeds have changed drastically in their composition from being predominantly marine-based to plant-based. This has altered the dietary supply and availability of micro-nutrients to Atlantic ...
    • Rib abnormalities and their association with focal dark spots in Atlantic salmon fillets 

      Jiménez-Guerrero, Raúl; Bæverfjord, Grete; Evensen, Øystein; Hamre, Kristin; Larsson, Thomas; Dessen, Jens-Erik; Gannestad, Kjellrun Hoås; Mørkøre, Turid (Peer reviewed; Journal article, 2022)
      Focal dark spots (DS) represent the most common quality problem in farmed Atlantic salmon (Salmo salar L.). DS are predominantly located in the cranio-ventral region of the fillet, that is characterized by the presence of ...
    • Safe limits of selenomethionine and selenite supplementation to plant-based Atlantic salmon feeds 

      Berntssen, Marc; Betancor, Mónica B.; Caballero, María José; Hillestad, Marie; Rasinger, Josef Daniel; Hamre, Kristin; Sele, Veronika; Amlund, Heidi; Ørnsrud, Robin (Journal article; Peer reviewed, 2018)
      The use of plant-based feeds warrants the supplementation with selenium (Se) to cover the requirement for Atlantic salmon. Depending on its chemical form, Se is a trace element with a narrow range between requirement and ...
    • A Screening Study on Effects Varying Dietary Macronutrient Composition on Gut Functions in Lumpfish (Cyclopterus lumpus) 

      Zhou, Weiwen; Hamre, Kristin; Chikwati, Elvis Mashingaidze; Kousoulaki, Katerina; Lein, Ingrid; Berge, Gerd Marit; Sæle, Øystein; Kortner, Trond M.; Krogdahl, Åshild (Peer reviewed; Journal article, 2022)
      Cultivation of lumpfish (Cyclopterus lumpus) as lice cleaner fish for salmon is now expanding. For successful cultivation of a new species, understanding the basic biology of digestive functions is vital to facilitate and ...
    • Seasonal Changes in Photoperiod: Effects on Growth and Redox Signaling Patterns in Atlantic Salmon Postsmolts
