Effekten av turbiditet i RAS-anlegg på gjellehelse målt i antall slimceller i gjellene hos atlantisk laks i settefiskproduksjon
Figenschou, Alexander J. Hat.; Hillestad, Linn-Anett (Student paper, others, 2019)I dette studiet ble det studert sammenhengen mellom turbiditet og antall slimceller i gjellene til atlantisk laks. Hypotesen var at høy turbiditet (og dermed lav siktdybde i vannkarene) i RAS-anlegg kan føre til økt mekanisk ... -
Erythroid Progenitor Cells in Atlantic Salmon (Salmo salar) May Be Persistently and Productively Infected with Piscine Orthoreovirus (PRV)
Malik, Muhammad Salman; Bjørgen, Håvard; Kannimuthu, Dhamotharan; Wessel, Øystein; Koppang, Erling Olaf; Di Cicco, Emiliano; Hansen, Elisabeth Furuseth; Dahle, Maria K; Rimstad, Espen (Journal article; Peer reviewed, 2019)Piscine orthoreovirus (PRV-1) can cause heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). The virus targets erythrocytes in the acute peak phase, followed by cardiomyocytes, before the ... -

A teleost structural analogue to the avian bursa of Fabricius
Løken, Oskar Mongstad; Bjørgen, Håvard; Hordvik, Ivar; Koppang, Erling Olaf (Peer reviewed; Journal article, 2019)The bursa of Fabricius is a primary and secondary lymphoid organ considered exclusively present in birds, and studies of this structure have been vital to our current understanding of the adaptive immune system of vertebrates. ... -
Variations in mucous cell numbers in gills of Atlantic salmon (Salmo salar) presmolt in commercial freshwater farms in Norway
Persson, David Erik Ludvig; Bjørgen, Håvard; Figenschou, Alexander Joachim Hatchek; Hillestad, Linn-Anett; Koppang, Erling Olaf; Nødtvedt, Ane C. W.; Stormoen, Marit (Peer reviewed; Journal article, 2020)Fish gills are heavily exposed to the external milieu and may react against irritants with different cellular responses. We describe variations in mucous cell counts in gills from healthy Atlantic salmon (Salmo salar) ... -
