Evaluation of Three Atlantic Salmon Strains for Resistance to Copepodid Sea Lice Attachment

Fishes
Sea lice have been a persistent pest of the salmon farming industry for more than 50 years. In this study, we aimed to identify if different strains of Atlantic salmon with discrete long-term lice exposure histories had variable resistance to copepodid ...

Sea lice prevention strategies affect cleaner fish delousing efficacy in commercial Atlantic salmon sea cages

Aquaculture Environment Interactions, 2020
Over the last 2 decades, cleaner fishes have been employed to remove external sea lice parasites from Atlantic salmon Salmo salar in sea cages. Norway, Scotland, Ireland, and the Faroe Islands combined now use ~60 million cleaner fish per year.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, Volume 109, Issue 2, Page 650-692, August 2026.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

The digestion time for salmon louse (Lepeoptheirus salmonis) in lumpfish (Cyclopterus lumpus) in relation to freshness, developmental stage, and temperature.

PLoS ONE
Sea lice infestations cause significant economic losses in the Atlantic salmon aquaculture industry. To biologically control sea lice at farming sites, cleaner fish such as lumpfish are employed. However, the efficacy of lumpfish is under constant debate,

Host–parasite transcriptomics during immunostimulant-enhanced rejection of salmon lice (Lepeophtheirus salmonis) by Atlantic salmon (Salmo salar)

FACETS, 2017
Salmon lice (Lepeophtheirus salmonis) are important ectoparasites of wild and farmed salmonids and cause major losses to the salmon farming industry throughout the Northern Hemisphere.

Sea trout adapt their migratory behaviour in response to high salmon lice concentrations [PDF]

, 2017
Sea trout face growth–mortality trade-offs when entering the sea to feed. Salmon lice epizootics resulting from aquaculture have shifted these trade-offs, as salmon lice might both increase mortality and reduce growth of sea trout.

Salmon lice infection on wild salmonids in marine protected areas: an evaluation of the Norwegian ‘National Salmon Fjords’

Aquaculture Environment Interactions, 2014
In Norway, 29 fjords and 52 rivers have been designated for protection in order to prevent the infection of important populations of wild salmonids with salmon lice of farm origin. We evaluated the effect of this protection on the lice infection pressure

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.

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

Aquaculture 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.
