    • Production of sterile Atlantic salmon by germ cell ablation with antisense oligonucleotides 

      Tveiten, Helge; Andersen, Øivind; Swain, Jaya Kumari; Johnsen, Hanne; Mommens, Maren; Slanchev, Krasimir (Journal article; Tidsskriftartikkel, 2023)
      Cultivation of sterile-only fish in aquaculture offers multiple benefits of environmental, economical, and social value. A reliable method for efficient sterilization without affecting fish welfare and performance traits would have significant impact on fish production practices. Here, we demonstrate sterilization of Atlantic salmon embryos by targeting the dead end gene with antisense oligonucleotides. ...

    • Ultrasonic imaging as a means of monitoring gonadal development in lumpfish (Cyclopterus lumpus) 

      Mlingi, Frank Thomas; Puvanendran, Velmurugu; Burgerhout, Erik; Tveiten, Helge; Tomkiewicz, Jonna; Kjørsvik, Elin; Mommens, Maren (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-21)
      The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, endoscopy, and gene expression analyses are costly, invasive, and often involve sacrificing the fish. We assessed the efficiency of ultrasound as a non-invasive method for monitoring ...
