Contrasting coping styles meet the wall: A dopamine driven dichotomy in behavior and cognition
Höglund, Erik; Silva, Patricia IM; Vindas, Marco Antonio; Øverli, Øyvind (Journal article; Peer reviewed, 2017) -
Contrasting neurochemical and behavioral profiles reflects stress coping styles but not stress responsiveness in farmed gilthead seabream (Sparus aurata)
Höglund, Erik; Moltesen, Maria; Castanheira, Maria Filipa; Thörnqvist, Per-Ove; Silva, Patricia IM; Øverli, Øyvind; Martins, Catarina; Winberg, Svante (Peer reviewed; Journal article, 2020)In fish, as well as in other vertebrates, contrasting suites of physiological and behavioral traits, or coping styles, are often shown in response to stressors. However, the magnitude of the response (i.e. stress responsiveness) ... -
Coping styles in farmed fish: consequences for aquaculture
Castanheira, Maria Filipa; Conceição, Luis E.C.; Millot, Sandie; Rey, Sonia; Bégout, Marie-Laure; Damsgård, Børge; Kristiansen, Tore S; Höglund, Erik; Øverli, Øyvind; Martins, Catarina I.M. (Journal article; Peer reviewed, 2017)Individual differences in physiological and behavioural responses to stressors are increasingly recognised as adaptive variation and thus raw material for evolution and fish farming improvements including selective breeding. ... -
Dietary l-tryptophan leaves a lasting impression on the brain and the stress response
Höglund, Erik; Øverli, Øyvind; Andersson, Madelene Åberg; Silva, Patricia; Laursen, Danielle Caroline; Moltesen, Maria M; Krogdahl, Åshild; Schjolden, Joachim; Winberg, Svante; Vindas, Marco Antonio; Mayer, Ian; Hillestad, Marie (Journal article; Peer reviewed, 2017) -
Effects of repeated short episodes of environmental acidification on Atlantic salmon (Salmo salar) from a landlocked population
Höglund, Erik; Høgberget, Rolf; Åtland, Åse; Haraldstad, Tormod; Øverli, Øyvind; Vindas, Marco A (Peer reviewed; Journal article, 2021)Chronic or repeated exposure to environmental contaminants may result in allostatic overload, a physiological situation in which the costs of coping affect long-term survival and reproductive output. Continuous measurements ... -
Proactive avoidance behaviour and pace-of-life syndrome in Atlantic salmon
Damsgård, Børge; Evensen, Tor Hatten; Øverli, Øyvind; Gorissen, Marnix; Ebbesson, Lars O.E.; Rey, Sonia; Höglund, Erik (Journal article; Peer reviewed, 2019) -
Welfare effects of environmental hypercapnia quantified by indicators based on morphology and allostatic load in Atlantic salmon (Salmo salar)
Höglund, Erik; Folkedal, Ole; Aerts, Johan; Hvas, Malthe; Øverli, Øyvind; Mangor-Jensen, Anders; Vindas, Marco A.; Nilsson, Jonatan; Kristiansen, Tore (Peer reviewed; Journal article, 2023)Water supply is a limited resource in most salmon hatcheries, which is compensated by reduced water flow and oxygenation. However, reduced water exchange can lead to accumulation of CO2, resulting in environmental hypercapnia, ...
