Salmon lice increase the age of returning Atlantic salmon [PDF]
Biology Letters, 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.

Sampling planktonic salmon lice in Norwegian fjords [PDF]
Aquaculture Environment Interactions, 2019 Risk of mortality of wild salmon caused by salmon lice is used as an index for managing aquaculture production in Norway and is based on monitoring of lice attached to wild salmonids and modelled concentrations of lice larvae in fjords.

Identifying salmon lice transmission characteristics between Faroese salmon farms [PDF]
Aquaculture Environment Interactions, 2018 Sea lice infestations are an increasing challenge in the ever-growing salmon aquaculture sector and cause large economic losses. The high salmon production in a small area creates a perfect habitat for parasites.

Farmed salmonids drive the abundance, ecology and evolution of parasitic salmon lice in Norway
Aquaculture Environment Interactions, 2021 Sea cage fish farming is typically open to the environment, with disease transmission possible between farmed and wild hosts. In salmonid aquaculture, salmon louse Lepeophtheirus salmonis infestations cause production losses, reduce welfare for farmed ...

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.

Frontiers in Marine Science, 2020 Phenylalanine hydroxylase (PAH) is a crucial enzyme involved in tyrosine biosynthesis, having roles in neurological and physiological processes. The purpose of PAH has received little attention in crustaceans despite extensive investigations in other ...

Applied Microbiology, 2023 Salmon lice (Lepeophtheirus salmonis) constitute a major challenge during the production of farmed Atlantic salmon in Norway. Preventive measures are considered to have a higher impact on sustainable control than lice treatment.

Dispersion of salmon lice in the Hardangerfjord [PDF]
Marine Biology Research, 2013 AbstractThe abundance of salmon lice in the Hardangerfjord is potentially large enough to be a threat to the wild fish stocks of the fjord. The salmon louse spends a period of 2–4 weeks in its planktonic stages drifting in the current of the upper water masses of the fjord looking for suitable hosts on which to settle.

Fishes, 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 delousing.

Relationship of farm salmon, sea lice, and wild salmon populations [PDF]
Proceedings of the National Academy of Sciences, 2010 Increased farm salmon production has heightened concerns about the association between disease on farm and wild fish. The controversy is particularly evident in the Broughton Archipelago of Western Canada, where a high prevalence of sea lice (ectoparasitic copepods) was first reported on juvenile wild pink salmon (
