In vivo studies of respiratory physiology in Arctic charr (Salvelinus alpinus) and Atlantic cod (Gadus morhua) exposed to aquaculture relevant levels of hypoxia, hyperoxia and hypercapnia

Karlsson, Anders (PhD Thesis;2010:34, Doctoral thesis, 2010)

Fish in aquaculture will be exposed to water oxygen and carbon dioxide levels that they do not normally encounter in the wild. These unnatural environmental conditions may be challenging to fish as they may lack the proper ...

Introduced European minnow Phoxinus phoxinus in alpine lakes may increase total mercury concentration in brown trout Salmo trutta

Borgstrøm, Reidar; Rognerud, Sigurd; Meland, Sondre; Rosseland, Bjørn Olav (Peer reviewed; Journal article, 2021)

In Norway, the cyprinid European minnow Phoxinus phoxinus has been spread far outside its previous natural distribution area, with lots of establishments in mountain lakes where brown trout Salmo trutta originally was the ...

Påvirkes laksesmolt av aluminium i brakkvann?Telemetriundersøkelser i Storelva i Holt, Aust-Agder,2007

Kroglund, Frode; Høgberget, Rolf; Haraldstad, Tormod; Økland, Finn; Thorstad, Eva Bonsak; Teien, Hans-Christian; Rosseland, Bjørn Olav; Salbu, Brit; Nilsen, Tom Ole; Stefansson, Sigurd Olav; Guttrup, Jim (NIVA-rapport;6245-2011, Research report, 2011)

Storelva har vært fullkalket siden 1996. Kalkingen har ikke gitt den forventede økningen i fangst av laks. Vassdraget avviker således fra erfaringene man har fra andre kalka elver på Sørlandet. Flere hypoteser er ...

Påvirkes laksesmolt av aluminium i brakkvann?Telemtriundersøkelser Storelva i Holt, Aust-Agder,2008
