Acclimatisation with lice-infested salmon improves cleaner fish lice consumption [PDF]
Aquaculture Environment Interactions, 2021 Securing the welfare and maximising the lice removal efficacy of ~60 million cleaner fish used each year on salmonid farms is essential to develop a productive and ethical industry with low salmon lice Lepeophtheirus salmonis levels.

Salmon lice--impact on wild salmonids and salmon aquaculture. [PDF]
J Fish Dis, 2013 AbstractSalmon lice,Lepeophtheirus salmonis, are naturally occurring parasites of salmon in sea water. Intensive salmon farming provides better conditions for parasite growth and transmission compared with natural conditions, creating problems for both the salmon farming industry and, under certain conditions, wild salmonids.

Evaluation of a national operational salmon lice monitoring system—From physics to fish [PDF]
PLoS ONE, 2018 The Norwegian government has decided that the aquaculture industry shall grow, provided that the growth is environmentally sustainable. Sustainability is scored based on the mortality of wild salmonids caused by the parasitic salmon lice.

Variation in volatile organic compounds in Atlantic salmon mucus is associated with resistance to salmon lice infection [PDF]
Scientific Reports, 2022 Salmon lice are ectoparasites that threaten wild and farmed salmonids. Artificial selection of salmon for resistance to the infectious copepodid lice stage currently relies on in vivo challenge trials on thousands of salmon a year.

Protective Immunization of Atlantic Salmon (Salmo salar L.) against Salmon Lice (Lepeophtheirus salmonis) Infestation [PDF]
Vaccines, 2021 Vaccination against salmon lice (Lepeophtheirus salmonis) is a means of control that averts the negative effects of chemical approaches. Here, we studied the immunogenicity and protective effect of a vaccine formulation (based on a salmon lice-gut ...

Salmon lice in the Pacific Ocean show evidence of evolved resistance to parasiticide treatment [PDF]
Scientific Reports, 2022 Parasitic salmon lice (Lepeophtheirus salmonis) threaten the economic and ecological sustainability of salmon farming, and their evolved resistance to treatment with emamectin benzoate (EMB) has been a major problem for salmon farming in the Atlantic ...

Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis) [PDF]
Parasitology, 2023 Atlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish typically are infected only once.

Space-Time Modelling of the Spread of Salmon Lice between and within Norwegian Marine Salmon Farms [PDF]
PLoS ONE, 2013 Parasitic salmon lice are potentially harmful to salmonid hosts and farm produced lice pose a threat to wild salmonids. To control salmon lice infections in Norwegian salmonid farming, numbers of lice are regularly counted and lice abundance is reported ...

Salmon lice increase the age of returning Atlantic salmon [PDF]
Biol Lett, 2014 The global increase in the production of domestic farmed fish in open net pens has created concerns about the resilience of wild populations owing to shifts in host–parasite systems in coastal ecosystems. However, little is known about the effects of increased parasite abundance on life-history traits in wild fish populations.

Optimal salmon lice treatment threshold and tragedy of the commons in salmon farm networks [PDF]
Aquaculture, 2019 Abstract The ectoparasite Lepeophtheirus salmonis has for decades plagued salmon aquaculture by decreasing profits and impacting wild salmon stocks. To protect migrating wild salmon stocks and avoid excessive cross-farm infections, authorities require treatments when sea lice level reach a given threshold.
