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 ...

Sea Lice (Lepeophtheirus salmonis) Harbour Putative Fish Pathogens: Insights From Illumina and Nanopore Sequencing

Journal of Fish Diseases, EarlyView.
ABSTRACT Ectoparasites that penetrate host skin can act as biological or mechanical vectors for pathogens and, in some cases, serve as reservoirs. Crustacean ectoparasites of fish are potential vectors of pathogens, which is especially relevant for obligate pathogens (e.g., Aeromonas salmonicida) with limited seawater survival. Sea lice (Lepeophtheirus

The effect of temperature on ability of Lepeophtheirus salmonis to infect and persist on Atlantic salmon [PDF]

Journal of Fish Diseases, 2020
AbstractThe salmon louse (Lepeophtheirus salmonis) is an ecologically and economically important parasite of salmonid fish. Temperature is a strong influencer of biological processes in salmon lice, with development rate increased at higher temperatures.

Maternal inheritance of deltamethrin resistance in the salmon louse Lepeophtheirus salmonis (Krøyer) is associated with unique mtDNA haplotypes.

PLoS ONE, 2017
Parasitic infections by the salmon louse, Lepeophtheirus salmonis (Krøyer), cause huge economic damage in salmon farming in the northern hemisphere, with combined treatment costs and production losses in 2014 having been estimated at US$ 350 million for ...

Identification and characterisation of the ecdysone biosynthetic genes neverland, disembodied and shade in the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae). [PDF]

PLoS ONE, 2018
The salmon louse is a marine ectoparasitic copepod on salmonid fishes. Its lifecycle consists of eight developmental stages, each separated by a molt. In crustaceans and insects, molting and reproduction is controlled by circulating steroid hormones such

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, EarlyView.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

Vertical salmon lice behaviour as a response to environmental conditions and its influence on regional dispersion in a fjord system

Aquaculture Environment Interactions, 2014
The salmon louse Lepeophtheirus salmonis is a major parasite of salmon, and is able to travel between farms during its pelagic phases. We investigated the spatial dispersion of L.

Sex-biased gene expression and evolution of candidate reproductive transcripts in adult stages of salmon lice (Lepeophtheirus salmonis)

FACETS, 2019
The salmon louse Lepeophtheirus salmonis (Krøyer 1837) displays numerous sexually dimorphic characteristics. Insights into their underlying molecular components have only recently been explored, which serve to better understand both the basic biology of ...
