Brain serotonergic activation in growth-stunted farmed salmon: Adaption versus pathology
Vindas, Marco Antonio; Johansen, Ida Beitnes; Folkedal, Ole; Höglund, Erik; Gorissen, Marnix; Flik, Gert; Kristiansen, Tore S; Øverli, Øyvind (Journal article; Peer reviewed, 2016-05-25)Signalling systems activated under stress are highly conserved, suggesting adaptive effects of their function. Pathologies arising from continued activation of such systems may represent a mismatch between evolutionary ... -
Comparison of Norwegian health and welfare regulatory frameworks in salmon and chicken production
Gismervik, Kristine; Tørud, Brit; Kristiansen, Tore S; Osmundsen, Tonje Cecilie; Størkersen, Kristine Vedal; Medaas, Christian; Lien, Marianne Elisabeth; Stien, Lars Helge (Peer reviewed; Journal article, 2020)The health and welfare of farmed fish are often regarded with less concern than for other production animals. This review compares the Norwegian legal health and welfare frameworks for broiler chickens and farmed salmon, ... -
Computational animal welfare: Towards cognitive architecture models of animal sentience, emotion and wellbeing
Budaev, Sergei; Kristiansen, Tore S; Giske, Jarl; Eliassen, Sigrunn (Peer reviewed; Journal article, 2020)To understand animal wellbeing, we need to consider subjective phenomena and sentience. This is challenging, since these properties are private and cannot be observed directly. Certain motivations, emotions and related ... -

Does the thermal component of warm water treatment inflict acute lesions on Atlantic salmon (Salmo salar)?
Moltumyr, Lene; Gismervik, Kristine; Gu, Jinni; Gåsnes, Siri Kristine; Kristiansen, Tore S; Rønnestad, Ivar; Nilsson, Jonatan; Stien, Lars Helge (Peer reviewed; Journal article, 2020)Warm water treatment, i.e. exposure to sea water at a temperature of 28–34 °C for 20–30 s, has in recent years been widely used for delousing of Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) in ... -
Fish protection during fish production. Organizational conditions for fish welfare
Størkersen, Kristine Vedal; Osmundsen, Tonje Cecilie; Stien, Lars Helge; Medaas, Christian; Lien, Marianne Elisabeth; Tørud, Brit; Kristiansen, Tore S; Gismervik, Kristine (Peer reviewed; Journal article, 2021)Too many salmon die during production at Norwegian fish farms. Earlier research shows that most farmed salmon die in operations partly related to protection of the wild salmon (from salmon lice), but it is not known how ... -
Governing the welfare of Norwegian farmed salmon: three conflict cases
Stien, Lars Helge; Tørud, Brit; Gismervik, Kristine; Lien, Marianne Elisabeth; Medaas, Christian; Osmundsen, Tonje Cecilie; Kristiansen, Tore S; Størkersen, Kristine Vedal (Peer reviewed; Journal article, 2020)To obtain insight into perceptions of how fish welfare and health is governed in Norwegian aquaculture, this study investigates three conflict cases: salmon lice, pancreas disease and farm siting. Using surveys and in-depth ... -
