    • Arctic charr brain transcriptome strongly affected by summer seasonal growth but only subtly by feed deprivation 

      Striberny, Anja; Jørgensen, Even Hjalmar; Klopp, Christophe; Magnanou, Elodie (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-27)
      <i>Background</i>: The Arctic charr (<i>Salvelinus alpinus</i>) has a highly seasonal feeding cycle that comprises long periods of voluntary fasting and a short but intense feeding period during summer. Therefore, the charr represents an interesting species for studying appetite-regulating mechanisms in fish. <p> <p><i>Results</i>: In this study, we compared the brain transcriptomes of fed and ...

    • Environmental impacts of aquaculture and coexcisting industries 

      Evenset, Anita; Refseth, Gro Harlaug; Dale, Trine; Arnberg, Maj; Harendza, Astrid; Mikkelsen, Eirik Inge; Iversen, Audun; Sagerup, Kjetil; Striberny, Anja; Izquierdo-Gomez, David; Borgersen, Gunhild; Bjorbækmo, Marit Frederikke Markussen; Pedersen, Kristine Bondo; Eriksen, Katrine; Emaus, Per-Arne; Sparboe, Lars Olav; Robertsen, Roy; Steinsbø, Silje (Research report; Forskningsrapport, 2023)
      This is the final report for the project "Environmental impact of aquaculture and coexisting industries - scope for comprehensive regulation" - "MILJØREG". The project is funded by the Norwegian Fisheries and Aquaculture Industry's research funding. The main goal of the project has been to prepare a broad overview of the knowledge base related to the environmental impact of aquaculture, as well ...

    • Feeding and fasting in Arctic charr (Salvelinus alpinus (Linnaeus, 1758)): Central regulation of food intake in a highly seasonal fish species 

      Striberny, Anja (Doctoral thesis; Doktorgradsavhandling, 2018-05-22)
      Central control mechanisms of food intake vary between different fish species. Few studies have investigated the role of central appetite regulators in fish species that show natural seasonal variations in food intake. Yet, seasonal fishes are particularly interesting because their potential seasonally sliding set-points in appetite and energy homeostasis may reveal new information about the ...

    • Kunnskapskartlegging-produksjon av stor laksesmolt 

      Ytrestøyl, Trine; Jenssen, Iris; Wetterwald, Vibeke Emilsen; Striberny, Anja; Alvestad, René; Dam, Rùni; Mortensen, Heidi S.; Johansen, Ellie; Espmark, Åsa Maria Olofsdotter; Johansen, Lill-Heidi; Kolarevic, Jelena; Larsen, Jørund S; Sandberg, Merete Gisvold; Nilsen, Tom Ole (Research report; Forskningsrapport, 2023-05-26)
      Basert på forskning og erfaringer kan det gis noen anbefalinger for produksjon av storsmolt med tanke på sentrale produksjonsparametere i den landbaserte fasen av produksjonen. En temperatur på 10-12 °C anbefales for å sikre god vekst i sjøfase og redusere tidlig kjønnsmodning hos hannfisk. Det anbefales ikke å gå bort fra lysstyring for å indusere smoltifisering før det foreligger mer dokumentasjon ...

    • Modulation of intestinal growth and differentiation by photoperiod and dietary treatment during smoltification in Atlantic salmon (Salmo salar, L.) 

      Duarte, Vilma; Gaetano, Pasqualina; Striberny, Anja; Hazlerigg, David; Jørgensen, Even Hjalmar; Fuentes, Juan; Campinho, Marco A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)
      Atlantic salmon undergo smoltification, a process that prepares the fish to enter and thrive in seawater (SW). Several physiological changes occur during smolting, especially in osmoregulatory tissues, the gill, the kidney, and the intestine. Here we characterized the effects on intestinal morphogenesis of two different, commonly used smoltification regimes during the end of the freshwater phase, ...

    • Photoperiod and dietary treatment in freshwater modulate the short-term intestinal response to seawater in Atlantic salmon (Salmo salar) 

      Gaetano, Pasqualina; Duarte, Vilma; Striberny, Anja; Hazlerigg, David; Jørgensen, Even Hjalmar; Campinho, Marco A.; Fuentes, Juan (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-02)
      Stimulation and timing of smoltification are essential for successful Atlantic salmon (Salmo salar) aquaculture. This study investigated intestinal responses during dietary and photoperiod manipulation in freshwater (FW) and after a subsequent seven days residence in seawater (SW). “Small” and “large” Atlantic salmon parr (~40 g and ~ 130 g respectively) were treated in FW for 12 weeks and ...

    • Seasonal Differences in Relative Gene Expression of Putative Central Appetite Regulators in Arctic Charr (Salvelinus alpinus) Do Not Reflect Its Annual Feeding Cycle 

      Striberny, Anja; Ravuri, Chandra Sekhar; Jobling, Malcolm; Jørgensen, Even Hjalmar (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-30)
      The highly seasonal anadromous Arctic charr (Salvelinus alpinus) was used to investigate the possible involvement of altered gene expression of brain neuropeptides in seasonal appetite regulation. Pro-opiomelanocortin (POMCA1, POMCA2), Cocaine and amphetamine regulated transcript (CART), Agouti related Peptide (AgRP), Neuropeptide Y (NPY) and Melanocortin Receptor 4 (MC4-R) genes were examined. The ...
