Parasite spill-back from domestic hosts may induce an Allee effect in wildlife hosts [PDF]

, 2012
The exchange of native pathogens between wild and domesticated animals can lead to novel disease dynamics. A simple model reveals that the spill-back of native parasites\ud from domestic to wild hosts may cause a demographic Allee effect.

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

Pest 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.

Candidate genes for monitoring hydrogen peroxide resistance in the salmon louse, Lepeophtheirus salmonis

Parasites & Vectors, 2020
Background Hydrogen peroxide (H2O2) is one of the delousing agents used to control sea lice infestations in salmonid aquaculture. However, some Lepeophtheirus salmonis populations have developed resistance towards H2O2.

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

Aquaculture, 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.

Original observations of Desmozoon lepeophtherii, a microsporidian hyperparasite infecting the salmon louse Lepeophtheirus salmonis, and its subsequent detection by other researchers

Parasites & Vectors, 2011
A microsporidian hyperparasite, Desmozoon lepeophtherii, of the parasitic copepod Lepeophtheirus salmonis (salmon louse), infecting farmed Atlantic salmon (Salmo salar), was first discovered in the west of Scotland in 2000.

Phenylalanine Hydroxylase RNAi Knockdown Negatively Affects Larval Development, Molting and Swimming Performance of Salmon Lice

Frontiers in Marine Science, 2020
Phenylalanine hydroxylase (PAH) is a crucial enzyme involved in tyrosine biosynthesis, having roles in neurological and physiological processes. The purpose of PAH has received little attention in crustaceans despite extensive investigations in other ...

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 ...
