Cleaner fish growth, welfare and survival in Atlantic salmon sea cages during an autumn-winter production
Geitung, Lena; Wright, Daniel William; Oppedal, Frode; Stien, Lars Helge; Vågseth, Tone; Madaro, Angelico (Journal article; Peer reviewed, 2020)Cleaner fish used as a biological control agent against salmon lice is rapidly increasing in Atlantic salmon aquaculture. However, concerns have been raised about the welfare and mortality of cleaner fish in salmon cage ... -
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 (Peer reviewed; Journal article, 2017-01)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 ... -
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 (Peer reviewed; Journal article, 2019-09-13)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 (Peer reviewed; Journal article, 2018)Surface environment modification is a potential parasite control strategy in Atlantic salmon sea-cage farming. For instance, a temporary low salinity surface layer in commercial-scale snorkel sea-cages has coincided with ...
