The transcriptomic response of adult salmon lice (Lepeophtheirus salmonis) to reduced salinity

Comparative Biochemistry and Physiology Part D: Genomics and Proteomics, 2021
Salmon lice (Lepeophtheirus salmonis) are marine parasitic copepods living on salmonids and are challenging for salmon aquaculture. One of several treatment methods is the application of freshwater to the fish which can lead to lice loss. However, lab experiments have shown that salmon lice, acclimated to seawater, are capable of surviving for several ...

Genetic composition of facultatively anadromous brown trout Salmo trutta L. in a freshwater‐lake system

Journal of Fish Biology, Volume 109, Issue 3, Page 1747-1759, September 2026.
Abstract Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life‐history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions.

The use of prevalence as a measure of lice burden: a case study of Lepeophtheirus salmonis on Scottish Atlantic salmon, Salmo salar L., farms [PDF]

, 2009
This study investigates the benefits of using prevalence as a summary measure of sea lice infestation on farmed Atlantic salmon, Salmo salar L. Aspects such as sampling effort, the relationship between abundance and prevalence arising from the negative ...

Salmon louse Lepeophtheirus salmonis predominates over Caligus elongatus on Atlantic salmon post-smolts in central and western Norway

Aquaculture Environment Interactions
Atlantic salmon Salmo salar are exposed to parasitic sea lice as they enter the marine environment, particularly in areas with high densities of open net-pen salmon farming, where infestations can reach harmful levels.

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

Effect of environmental salinity on sea lice Lepeophtheirus salmonis settlement success [PDF]

Diseases of Aquatic Organisms, 2006
The sea louse Lepeophtheirus salmonis (Krøyer, 1837) (Copepoda: Caligidae) is an ectoparasite of salmonid fish. It has earlier been proposed that the free-swimming infectious copepodid stage of L. salmonis gather at river mouths to infect wild Atlantic salmon Salmo salar L. and sea trout S. trutta L. smolts during their seaward migration.

Monitoring parasitic abundance in cage-based aquaculture : the effects of clustering [PDF]

, 2006
Most discussions of sampling protocols within the literature on monitoring aquatic parasites are based on the assumptions of simple random sampling. There has been a growing recognition within the fields of human and terrestrial veterinary epidemiology ...

Spatiotemporally dependent relationship between salmon lice from salmon farms and infestation on juvenile Pacific salmon in British Columbia, Canada

Aquaculture Environment Interactions
This study examines the relationship between salmon lice Lepeophtheirus salmonis infestation pressure from Atlantic salmon farms and the prevalence of L. salmonis on wild juvenile Pacific salmon in British Columbia, Canada. We estimated weekly copepodids

High level efficacy of lufenuron against sea lice (Lepeophtheirus salmonis) linked to rapid impact on moulting processes

International Journal for Parasitology: Drugs and Drug Resistance, 2018
Drug resistance in the salmon louse Lepeophtheirus salmonis is a global issue for Atlantic salmon aquaculture. Multiple resistance has been described across most available compound classes with the exception of the benzoylureas.
