Risk assessment of the environmental impact of Norwegian Atlantic salmon farming
Taranger, Geir Lasse; Karlsen, Ørjan; Bannister, Raymond; Glover, Kevin; Husa, Vivian; Karlsbakk, Egil; Kvamme, Bjørn Olav; Boxaspen, Karin Kroon; Bjørn, Pål Arne; Finstad, Bengt; Madhun, Abdullah Sami; Morton, Hugh Craig; Svåsand, Terje (Journal article; Peer reviewed, 2014-09-02)Norwegian aquaculture has grown from its pioneering days in the 1970s to be a major industry. It is primarily based on culturing Atlantic salmon and rainbow trout and has the potential to influence the surrounding environment ... -
Seatrout (Salmo trutta) is a natural host for Parvicapsula pseudobranchicola (Myxozoa, Myxosporea), an important pathogen of farmed Atlantic salmon (Salmo salar)
Hansen, Haakon; Poppe, Trygve T; Markussen, Turhan; Karlsbakk, Egil (Journal article; Peer reviewed, 2015-04-10)Background: Parvicapsula pseudobranchicola (Myxozoa) causes widespread infections in farmed Atlantic salmon in northern Norway. Heavily infected salmon become runts, probably due to vision impairment or blindness. The salmon ... -
Snorkel sea-cage technology decreases salmon louse infestation by 75% in a full-cycle commercial test
Geitung, Lena; Oppedal, Frode; Stien, Lars Helge; Dempster, Timothy David; Karlsbakk, Egil; Nola, Velimir; Wright, Daniel William (Journal article; Peer reviewed, 2019)Methods to prevent parasite infestations in farmed fish are becoming widespread, yet tests of their effectiveness often lack commercial relevance and statistical power, which may lead to technology misuse. Here, we examined ... -
Surface environment modification in Atlantic salmon sea-cages: Effects on amoebic gill disease, salmon lice, growth and welfare
Wright, Daniel William; Geitung, Lena; Karlsbakk, Egil; Stien, Lars Helge; Dempster, Timothy David; Oldham, Tina; Nola, Velimir; Oppedal, Frode (Journal article; Peer reviewed, 2018)Surface environment modification is a potential parasite control strategy in Atlantic salmon sea-cage farming.

The gill parasite Paramoeba perurans compromises aerobic scope, swimming capacity and ion balance in Atlantic salmon.
Hvas, Malthe; Karlsbakk, Egil; Mæhle, Stig; Wright, Daniel William; Oppedal, Frode (Journal article; Peer reviewed, 2017)The parasitic amoeba Paramoeba perurans is an aetiological agent of amoebic gill disease (AGD), a serious problem in seawater salmonid aquaculture globally. Other finfish species are also infected and infection events may ...
