Salmon lice infection in wild salmonids in marine protected areas: Comment on Serra-Llinares et al. (2014)

Aquaculture Environment Interactions, 2016
Serra-Llinares et al. (2014; Aquacult Environ Interact 5:1-16) analysed the association between the estimated production of salmon louse copepodites in salmon farms and lice infection levels in wild salmonids.

Sea louse infection of juvenile sockeye salmon in relation to marine salmon farms on Canada's west coast.

PLoS ONE, 2011
BackgroundPathogens are growing threats to wildlife. The rapid growth of marine salmon farms over the past two decades has increased host abundance for pathogenic sea lice in coastal waters, and wild juvenile salmon swimming past farms are frequently ...

Effects of temporal, geographical and environmental factors on salmon lice (Lepeophtheirus salmonis) levels of Atlantic salmon (Salmo salar) in Ireland

Scientific Reports
The salmon louse (Lepeophtheirus salmonis) poses a major challenge for Atlantic salmon (Salmo salar) aquaculture in the northern hemisphere. These ectoparasites feed on the blood, tissue, and mucus of their fish host, causing skin damage, increasing ...

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

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 ...

The impact of functional feed on Atlantic salmon (Salmo salar) systemic immune response to high and low levels of sea lice infection (Lepeophtheirus salmonis) and co-infection with infectious salmon anemia virus

Comparative Immunology Reports
Due to the nature of open-pen farming, salmon are exposed to numerous pathogens shared by other farms and their wild counterparts. Industry must manage these outbreaks through vaccination, oral or bath treatments, and more recently through functional ...

Modeling dynamics of adult female lice at salmon farming sites in Eastern Canada: a stochastic, state-based approach

Frontiers in Aquaculture
IntroductionSea lice are parasitic copepods that harm salmon health, reduce farm productivity, and create ecological and economic challenges for aquaculture.MethodsA stochastic, state-based, time-dependent epidemiological model was developed to ...

A gap analysis on modelling of sea lice infection pressure from salmonid farms. II. Identifying and ranking knowledge gaps: output of an international workshop

Aquaculture Environment Interactions
Sea lice are a major health hazard for farmed Atlantic salmon in Europe, and their impact is felt globally. Given the breadth of ongoing research in sea lice dispersal and population modelling, and focus on research-led adaptive management, we brought ...
