Effect of environmental salinity on sea lice Lepeophtheirus salmonis settlement success [PDF]

Diseases of Aquatic Organisms, 2006
The sea louse Lepeophtheirus salmonis (Krøyer, 1837) (Copepoda: Caligidae) is an ectoparasite of salmonid fish. It has earlier been proposed that the free-swimming infectious copepodid stage of L. salmonis gather at river mouths to infect wild Atlantic salmon Salmo salar L. and sea trout S. trutta L. smolts during their seaward migration.

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,

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Life history and virulence are linked in the ectoparasitic salmon louse Lepeophtheirus salmonis [PDF]

Journal of Evolutionary Biology, 2012
AbstractModels of virulence evolution for horizontally transmitted parasites often assume that transmission rate (the probability that an infected host infects a susceptible host) and virulence (the increase in host mortality due to infection) are positively correlated, because higher rates of production of propagules may cause more damages to the host.

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.

Behaviour and Dispersal of Mobile Salmon Lice When Detached From the Host

Journal of Fish Diseases, Volume 48, Issue 11, November 2025.
ABSTRACT Sea lice can flourish when salmon are farmed in open sea‐cages, necessitating treatments to control outbreaks and reduce larval export. However, mobile ectoparasitic stages can be dislodged during crowding or other procedures, and potentially reinfest farmed or wild fish.

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 ...

Modelling the Effectiveness of Gene‐Edited Salmon at Sea Lice Control and the Use of Refugia to Mitigate Counter‐Adaptation

Evolutionary Applications, Volume 18, Issue 10, October 2025.
ABSTRACT Advances in gene‐editing technologies offer opportunities to improve disease management in aquaculture. Gene‐editing applications for farmed Atlantic salmon (Salmo salar) include harnessing innate parasite resistance to protect against salmon lice (Lepeophtheirus salmonis).

Modulation of Sodium and Ammonia Transporters in the Context of Viral Gill Diseases in Common Carp (Cyprinus carpio)

Journal of Fish Diseases, Volume 48, Issue 10, October 2025.
ABSTRACT Osmoregulation and ammonia removal are among key physiological processes that take place in gills and affect fish homeostasis and well‐being. These processes can be disrupted by numerous environmental factors, but also by viral infections, especially those leading to severe gill disorders.

Ingestion of Lepeophtheirus salmonis by the blue mussel Mytilus edulis

Aquaculture, 2011
Abstract Integrated multi-trophic aquaculture (IMTA) is an exciting alternative approach to mono-culture aquaculture that reduces environmental impacts of commercial aquaculture systems by combining the cultivation of fed aquaculture species (finfish) with extractive aquaculture species (e.g., shellfish and seaweed). This increases the sustainability
