Journal ArticleDOI
mRNA expression of antioxidant enzymes (SOD, CAT and GSH-Px) and lipid peroxidative stress in liver of Atlantic salmon (Salmo salar) exposed to hyperoxic water during smoltification
Pål A. Olsvik,Torstein Kristensen,Rune Waagbø,Bjørn Olav Rosseland,Knut Erik Tollefsen,Grete Baeverfjord,Marc H.G. Berntssen +6 more
TL;DR: Overall, the mRNA expression of SOD, CAT and GSH-Px in liver related poorly with the hyperoxic exposure regimes, and more knowledge are needed before the expressed levels of these antioxidant genes can be applied as biomarkers of hyperoxia in Atlantic salmon.
Journal ArticleDOI
Bioaccumulation of persistent organic pollutants (POPs) in fish species from Lake Koka, Ethiopia: The influence of lipid content and trophic position.
Ermias Deribe,Bjørn Olav Rosseland,Reidar Borgstrøm,Brit Salbu,Zinabu Gebre-Mariam,Elias Dadebo,Hans Ragnar Norli,Ole Martin Eklo +7 more
TL;DR: The significant (P<0.05) relationship between concentrations of DDTs and δ(15)N indicates that DDTs biomagnified in the food web of the lake, and ongoing use ofDDTs in the study area and recent exposure of these fish species are indicated.
Journal ArticleDOI
Bioaccumulation of organochlorine pollutants in the fish community in Lake Årungen, Norway
TL;DR: DDTs were the dominant among all analyzed OCs, and Sigma PCB and HCB, detected in fish from two clearly distinct trophic levels (prey and predators), give an indication of biomagnification.
Journal ArticleDOI
Multiple stressors--a challenge for the future.
Journal ArticleDOI
Effects of hypo- and hyperoxia on transcription levels of five stress genes and the glutathione system in liver of Atlantic cod Gadus morhua.
Pål A. Olsvik,Torstein Kristensen,Rune Waagbø,Knut Erik Tollefsen,Bjørn Olav Rosseland,H. Toften +5 more
TL;DR: Prolonged exposure to unfavourable oxygen saturation levels did not alter the OSI, indicating that the antioxidant glutathione system is maintained at an unchanged level in liver of the examined cod.
