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

It works! Lumpfish can significantly lower sea lice infestation in large-scale salmon farming

Biology Open, 2018
To assess the efficacy of lumpfish grazing on attached sea lice on Atlantic salmon, six large-scale sea cages, (130 m circumference, 37,688 m3 volume) each stocked with approximately 200,000 salmon 0+ smolts, were stocked with a 4, 6 and 8% density (8000,

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 ...

The Disease Burden in Fish Farm Management: An Integrative View and a Specific Vision in Europe

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT In aquaculture, the interactions and balance—or imbalance—between the fish, the rearing environment, pathogens, and farm management determine the occurrence and impact of clinical diseases. The global assessment of the factors related to disease impact is commonly referred to as disease burden.

Using sentinel cages to estimate infestation pressure on salmonids from sea lice in Loch Shieldaig, Scotland

Aquaculture Environment Interactions, 2014
Sentinel Atlantic salmon, held in cages, were used to estimate the monthly infestation pressure of sea lice at 3 locations along a salmonid migration route in Loch Shieldaig, a Scottish west coast sea loch.

Infection threshold to estimate Lepeophtheirus salmonis-associated mortality among juvenile pink salmon [PDF]

Diseases of Aquatic Organisms, 2009
A threshold of lethal infection was estimated from previous controlled laboratory exposures to be 7.5 Lepeophtheirus salmonis g(-1) for pink salmon Oncorhynchus gorbuscha averaging < 0.7 g. This threshold was used to assess the risk of mortality caused by L.

Revisiting Vitamin and Trace Mineral Nutrition in Atlantic Salmon Farming With Emphasis on Fish Health

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Atlantic salmon farming is faced with numerous environmental and production‐related challenges affecting fish health and welfare, globally and in Norway. An animal's requirement for a nutrient is the sum of the required supply of available nutrients for maintenance, growth, reproduction, health, and disease resistance.

Effect of temperature on development rate and egg production in Caligus elongatus and other sea louse species

Aquaculture Environment Interactions
The sea louse Caligus elongatus (Siphonostomatoida, Caligidae) is a generalist ectoparasite commonly found on farmed salmonids in the Atlantic Ocean. Together with the salmon louse Lepeophtheirus salmonis and the Chilean sea louse Caligus rogercresseyi ...

Local and systemic gene expression responses of Atlantic salmon (Salmo salar L.) to infection with the salmon louse (Lepeophtheirus salmonis) [PDF]

, 2008
Background The salmon louse (SL) is an ectoparasitic caligid crustacean infecting salmonid fishes in the marine environment. SL represents one of the major challenges for farming of salmonids, and veterinary intervention is necessary to combat infection.
