Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

open access: yesJournal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

Sequence variation in four mitochondrial genes of the salmon louse Lepeophtheirus salmonis [PDF]

open access: yesDiseases of Aquatic Organisms, 2006
A total of 210 Lepeophtheirus salmonis collected from 7 locations (Scotland, Russia, Canada, Japan and 3 locations in Norway), were screened for sequence variation in 4 mitochondrial genes; ATPase subunit 6 (A6), Cytochrome b oxidase subunit I (COI), Cytochrome b (Cyt b) and 16S rRNA.

Risk Is Not Equal to Impact: The Challenges of Developing a Traffic Light System to Regulate Farmed Salmon Production on an Ecosystem Scale

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT We review information on salmon farming production, environmental and climatic variables covering all salmon farming areas in the Patagonia marine ecosystems over a 10‐year period in Chile. With this information, we develop a semi‐quantitative Environmental and Productive Risk Assessment (RA) model as a guide for the design of a Traffic Light ...

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

open access: yesPest Management Science, Volume 82, Issue 5, Page 4661-4668, May 2026.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Health of Wild Atlantic Salmon (Salmo salar) Smolts Along Coastal Migratory Routes in Newfoundland, Canada With and Without Salmonid Aquaculture as Assessed Using Sentinel Cages

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Declines in wild Atlantic salmon populations in the North Atlantic with migratory routes adjacent to commercial salmonid aquaculture operations in coastal marine environments have raised concerns about the potential for direct or indirect effects this industry may have on local wild populations.

Salmon louse Lepeophtheirus salmonis predominates over Caligus elongatus on Atlantic salmon post-smolts in central and western Norway

open access: yesAquaculture Environment Interactions
Atlantic salmon Salmo salar are exposed to parasitic sea lice as they enter the marine environment, particularly in areas with high densities of open net-pen salmon farming, where infestations can reach harmful levels.

High level efficacy of lufenuron against sea lice (Lepeophtheirus salmonis) linked to rapid impact on moulting processes

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance, 2018
Drug resistance in the salmon louse Lepeophtheirus salmonis is a global issue for Atlantic salmon aquaculture. Multiple resistance has been described across most available compound classes with the exception of the benzoylureas.

Scientists' Warning on the Rapid Evolution of Parasites in the Anthropocene

open access: yesEvolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Human activities are changing the natural world at an accelerating pace, and as a consequence exerting novel and often strong selection pressures on living organisms. For species with traits conferring huge inherent evolutionary potential, like parasites, the outcome may be rapid adaptive responses spanning multiple phenotypic traits. The rise

Spatiotemporally dependent relationship between salmon lice from salmon farms and infestation on juvenile Pacific salmon in British Columbia, Canada

open access: yesAquaculture 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

Effects of salmon lice on numbers and size distributions of Atlantic salmon returning to spawn in Norwegian rivers

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
This study presents a quantitative relationship between infestations of post‐smolt recruits and size‐structured returns of mature salmon to Norwegian rivers, suggesting that louse infestation from farms may reduce returns of spawners and re‐structure the size distribution of mature river populations of Atlantic salmon.
