Sea lice and salmon population dynamics: effects of exposure time for migratory fish [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2009
The ecological impact of parasite transmission from fish farms is probably mediated by the migration of wild fishes, which determines the period of exposure to parasites. For Pacific salmon and the parasitic sea louse, Lepeophtheirus salmonis , analysis of the exposure period may resolve conflicting observations of ...

Sea lice removal by cleaner fish in salmon aquaculture: a review of the evidence base

Aquaculture Environment Interactions, 2020
Stocking cleaner fish to control sea lice infestations in Atlantic salmon farms is widespread and is viewed as a salmon welfare-friendly alternative to current delousing control treatments.

Individual fish tank arrays in studies of Lepeophtheirus salmonis and lice loss variability [PDF]

Diseases of Aquatic Organisms, 2011
In studies of the salmon louse Lepeophtheirus salmonis (Krøyer, 1837), experimental design is complicated by a highly variable and unpredictable lice loss among common experimental tanks and a substantial rate of host transfer within tanks. When fish hosting L. salmonis are maintained in individual tanks, unspecific effects such as host transfer, louse

Generation of quantifiable knowledge about delouse treatments of salmon – The case of Hydrolicer®/Hydroflow treatments

Aquaculture Reports, 2023
Controlling the salmon lice problem is at the very core of the salmon farming industry’s growth challenges. One group of methods to control lice is the mechanical treatment methods.

Crowding causes detachment and loss of mobile sea lice: Fine-meshed crowding nets may mitigate spread

Aquaculture Reports
Detachment of mobile lice from salmon during crowding and handling procedures in sea-cage fish farms may lead to loss and unwanted spread of ectoparasitic sea lice to other cages, farms or wild fish.

Salmon lice dispersion in a northern Norwegian fjord system and the impact of vertical movements

Aquaculture Environment Interactions, 2016
The abundance and distribution of salmon lice Lepeophtheirus salmons originating from fish farms in a northern Norwegian fjord during the summer of 2010 was investigated by means of a numerical model, underpinned by field observations.

Sea lice (Copepoda: Caligidae) parasitic on fishes reported from the Neotropical region [PDF]

Neotropical Biodiversity, 2016
The Caligidae, also known as sea lice, is a family of parasitic copepods of fish that consists of 31 genera and more than 450 species, some of which have been deleterious to cultured fish. The goal of this paper was to structure a list of sea lice species known from the Neotropical region based on information from published records.

Sea Lice (Lepeophtheirus salmonis) Infestation Reduces the Ability of Peripheral Blood Monocytic Cells (PBMCs) to Respond to and Control Replication of Salmonid Alphavirus in Atlantic Salmon (Salmo salar L.)

Viruses, 2020
Here we have studied the impact of lice (Lepeophtheirus salmonis) infestation of donor fish on the ability of isolated peripheral blood monocytes (PBMCs) to control the replication of salmonid alphavirus (SAV) ex vivo.
