An update of the salmon louse (Lepeophtheirus salmonis) reference genome assembly

G3: Genes, Genomes, Genetics, 2022
Salmon lice have plagued the salmon farming industry and have negatively impacted salmon populations in the wild. In response, researchers have generated high density genetic maps, genome assemblies, transcriptomes, and whole-genome resequencing data to ...

The control of sea lice in Atlantic salmon by selective breeding [PDF]

Journal of The Royal Society Interface, 2015
Sea lice threaten the welfare of farmed Atlantic salmon and the sustainability of fish farming across the world. Chemical treatments are the major method of control but drug resistance means that alternatives are urgently needed. Selective breeding can be a cheap and effective alternative.

The Cost of Lice: Quantifying the Impacts of Parasitic Sea Lice on Farmed Salmon

Marine Resource Economics, 2017
AbstractDiseases are an important challenge in aquaculture. However, most of what is known about the effect of diseases comes from laboratory experiments. Using a farm-level data set containing sea lice infestation counts for all Norwegian salmon farms over an 84-month period, we empirically investigate the biological and economic impacts of observed ...

Sea lice on wild juvenile Pacific salmon and farmed Atlantic salmon in the northernmost salmon farming region of British Columbia [PDF]

, 2011
The Kitasoo/Xai'xais First Nation established a program to monitor sea lice levels on seaward migrating wild juvenile salmon in their traditional territory which contains the most northerly salmon farming region of British Columbia.

Understanding sources of sea lice for salmon farms in Chile [PDF]

Preventive Veterinary Medicine, 2013
The decline of fisheries over recent decades and a growing human population has coincided with an increase in aquaculture production. As farmed fish densities increase, so have their rates of infectious diseases, as predicted by the theory of density-dependent disease transmission.

DEVELOPMENT AND DISPERSAL OF SALMON LICE (LEPEOPHTHEIRUS SALMONIS KRØYER 1837) IN COMMERCIAL SALMON FARMING LOCALITIES [PDF]

, 2020
The development and dispersal of salmon lice (Lepeophtheirus salmonis) were studied in an intensive aquaculture production site in central Norway, practicing coordinated production cycles.

A Salmon Lice Prediction Model

Preventive Veterinary Medicine
Salmon lice (Lepeophtheirus salmonis) are parasites on salmonid fish and a density-dependent constraint to the sustainable farming of salmonids in open net pens. To control the parasites, fish farmers in Norway are required to count the number of salmon lice in different developmental stages on a subset of the fish each week.

Temporal and spatial variations in lice numbers on salmon farms in the Hardanger fjord 2004-06

, 2009
The long and narrow Hardanger fjord in western Norway has a high density of salmon farms and has had severe salmon lice, Lepeophtheirus salmonis, problems.

Effects of salmon lice Lepeophtheirus salmonis on wild sea trout Salmo trutta—a literature review

Aquaculture Environment Interactions, 2015
Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, skin and muscle, and infestation

Fluorescence for non-contact detection of living salmon lice on salmon skin

Journal of the European Optical Society-Rapid Publications, 2023
This work presents a promising method for automatic, non-contact, detection and counting of salmon lice infested on salmon in an aquacultural farm setting. The method uses fluorescence from chitin in the visual part of spectrum to enhance the contrast between fish skin and salmon lice, and show that the fluorescence is even strong enough to give a real-
