(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-14)Piscine red blood cells (RBC) are nucleated and have been characterized as mediators of immune responses in addition to their role in gas exchange. Salmonid RBC are major target cells of Piscine orthoreovirus-1 (PRV-1), the etiological agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). PRV-1 replicates in RBC ex vivo, but no viral amplification has been ... -
Evaluering av fangstskader ved bruk av hyperspektral avbildning
(Research report; Forskningsrapport, 2024-04-04)Metoden «Fangstskadeindeks» for sensorisk kvalitetsvurdering og registrering av ulike skader som kan oppstå på torsk under fangst og håndtering av torsk er tidkrevende. Det vil være en fordel om slik kvalitetsvurdering kan gjøres instrumentelt. De fleste av fangstskadene medfører bloduttredelser i muskelen, og en aktuell instrumentell metode kan derfor være hyperspektral avbildning som kan ... -

Instigating transformation within longstanding governance arrangements is very challenging and is often hampered by institutional barriers such as path dependency, ... -
Effect of Calanus finmarchicus Hydrolysate Inclusion on Diet Attractiveness for Whiteleg Shrimp (Litopenaeus vannamei)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-13)Shrimp feed formulations have moved towards less fish meal and more of the readily available and cheaper plant proteins. To counteract the lower attractiveness and palatability of plant proteins, feeds are supplemented with ingredients known to have chemoattractive properties that will increase feed intake. This study investigated the putative chemoattractive effect of Calanus finmarchicus hydrolysate, ... -
