Cleaner Fish Do Not Impact the Pigmentation of Salmon Lice (Lepeophtheirus salmonis) in Commercial Aquaculture Cages
Imsland, Albert; Berg, Jon Petter; Nola, Velimir; Geitung, Lena; Oldham, Tina Marie Wier (Peer reviewed; Journal article, 2023)Salmon lice are one of the biggest challenges to sustainable salmonid aquaculture. The species display high evolutionary potential, which is evident by its development of resistance to numerous chemical compounds used for ... -
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 (Peer reviewed; Journal article, 2020)Cleaner fish used as a biological control agent against salmon lice is rapidly increasing in Atlantic salmon aquaculture.

Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
Bui, Samantha; Geitung, Lena; Oppedal, Frode; Barrett, Luke T. (Peer reviewed; Journal article, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
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. For instance, a temporary low salinity surface layer in commercial-scale snorkel sea-cages has coincided with ... -
Tapeworm (Eubothrium sp.) infestation in sea caged Atlantic salmon decreased by lice barrier snorkels during a commercial-scale study
Geitung, Lena; Wright, Daniel William; Stien, Lars Helge; Oppedal, Frode; Karlsbakk, Egil Erlingsson (Peer reviewed; Journal article, 2021)Reports of infestation by marine parasitic tapeworms (Eubothrium sp.) and an associated growth reduction in Norwegian farmed salmon are on the rise. With few acceptable treatment options available, due to drug resistance ...
