Salmon Louse Infestation Impairs the Long‐Term Survival of Sea‐Run Brown Trout [PDF]

Ecology and Evolution
Anadromous salmonids, including sea‐run brown trout, are exposed to ectoparasitic salmon lice during their sea migrations. The development of intensive aquaculture in coastal areas has promoted louse epidemics by substantially increasing the number of ...

Evaluation of a national operational salmon lice monitoring system—From physics to fish

PLOS ONE, 2018
The Norwegian government has decided that the aquaculture industry shall grow, provided that the growth is environmentally sustainable. Sustainability is scored based on the mortality of wild salmonids caused by the parasitic salmon lice. Salmon lice infestation pressure has traditionally been monitored through catching wild sea trout and Arctic char ...

Statistical and ecological challenges of monitoring parasitic salmon lice infestations in wild salmonid fish stocks

Aquaculture Environment Interactions, 2015
Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling.

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

Pest Manag Sci
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.

Cleaner Fish Do Not Impact the Pigmentation of Salmon Lice (Lepeophtheirus salmonis) in Commercial Aquaculture Cages

Fishes, 2023
Salmon lice are one of the biggest challenges to sustainable salmonid aquaculture. The species display high evolutionary potential, which is evident by its development of resistance to numerous chemical compounds used for delousing.

Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis)

Parasitology, 2023
Atlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish typically are infected only once.

Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk. [PDF]

J Fish Dis
ABSTRACT Piscirickettsia salmonis, the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.

Farmed salmonids drive the abundance, ecology and evolution of parasitic salmon lice in Norway

Aquaculture Environment Interactions, 2021
Sea cage fish farming is typically open to the environment, with disease transmission possible between farmed and wild hosts. In salmonid aquaculture, salmon louse Lepeophtheirus salmonis infestations cause production losses, reduce welfare for farmed ...

Prevalence of fish lice, Argulus (Crustacea: Branchiura) in freshwater and two ornamental fishes of Iran

Journal of Fisheries, 2022
Farming and trading of aquarium fish has been considered a popular pastime in the world. Most of Iran's aquarium fish are imported from Asian countries including Indonesia, Malaysia, Thailand and Vietnam. Fish lice (Argulus) is known as one of the most important and common ectoparasites in ornamental fish.

Temporal and spatial variations in lice numbers on salmon farms in the Hardanger fjord 2004-06 [PDF]

, 2009
The long and narrow Hardanger fjord in western Norway has a high density of salmon farms and has had severe salmon lice, Lepeophtheirus salmonis, problems.
