Characterisation of proteins in excretory/secretory products collected from salmon lice, Lepeophtheirus salmonis [PDF]

Parasites & Vectors, 2018
Background The salmon louse, Lepeophtheirus salmonis, is an ectoparasitic copepod which feeds on the mucus, skin and blood of salmonid fish species. The parasite can persist on the surface of the fish without any effective control being exerted by the ...

Evidence for the Evolution of Resistance to Non‐Chemical Parasite Controls: Salmon Lice From Submerged Cages Produce Larvae That Swim Deeper

Evolutionary Applications
Salmon lice (Lepeophtheirus salmonis) pose a major challenge to the sustainability of salmon aquaculture due to their capacity to rapidly evolve resistance to parasite control methods.

Microbial communities associated with the parasitic copepod Lepeophtheirus salmonis [PDF]

Marine Genomics, 2020
Abstract Lepeophtheirus salmonis is a naturally occurring marine parasite of salmonid fishes in the Northern hemisphere, and a major problem in salmonid aquaculture. In addition to the direct effects on host fish, L. salmonis may act as a vector for diseases. Here, the microbial community of L.

The salmon louse genome may be much larger than sequencing suggests

Scientific Reports, 2022
The genome size of organisms impacts their evolution and biology and is often assumed to be characteristic of a species. Here we present the first published estimates of genome size of the ecologically and economically important ectoparasite ...

In lumpfish We Trust? The Efficacy of Lumpfish Cyclopterus lumpus to Control Lepeophtheirus salmonis Infestations on Farmed Atlantic Salmon: A Review

Fishes, 2022
In this review, we have systematized current knowledge about the effect of stocking lumpfish (Cyclopterus lumpus) as cleaner fish to control Lepeophtheirus salmonis infestations on farmed Atlantic salmon (Salmo salar L.).

Sea Lice Are Sensitive to Low Frequency Sounds

Journal of Marine Science and Engineering, 2021
The salmon louse Lepeophtheirus salmonis is a major disease problem in salmonids farming and there are indications that it also plays a role in the decline of wild salmon stocks.

Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo [PDF]

BMC Genetics, 2014
The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have been reported between lice from the two oceans.

Identification and Molecular Characterization of Two Acetylcholinesterases from the Salmon Louse, Lepeophtheirus salmonis. [PDF]

PLoS ONE, 2015
Acetylcholinesterase (AChE) is an important enzyme in cholinergic synapses. Most arthropods have two genes (ace1 and ace2), but only one encodes the predominant synaptic AChE, the main target for organophosphates.

Frontal Filament Morphogenesis in the Salmon Louse Lepeophtheirus salmonis [PDF]

The Journal of Parasitology, 2001
The objective of the present study was to understand how and when the frontal filament (FF) in the salmon louse Lepeophtheirus salmonis is produced by examining the sequence of morphological changes leading to FF production in the copepodid and early chalimus stages. Atlantic salmon (Salmo salar) were heavily infested with newly molted copepodids.
