Modeling salmon lice effects on sea trout population dynamics using an individual-based approach

Aquaculture Environment Interactions, 2021
Salmon lice Lepeophtheirus salmonis infestation of sea trout Salmo trutta results in both additional marine mortality and behavioral changes which may contribute to sea trout population decline.

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.

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Salmon‐lice as a potential threat to anadromous Arctic charr populations

Journal of Fish Diseases, 2023
AbstractSalmon‐lice have the potential to change the behaviour and growth of their salmonid host species. Here, the baseline infection levels of salmon‐lice of post‐smolts (n = 815) and veteran migrants (n = 875) of sea‐run Arctic charr (Salvelinus alpinus Linnaeus, 1758) were monitored over two successive years in a sub‐Arctic Norwegian fjord without ...

Follow-Up Study on Acoustic De-Licing of Atlantic Salmon (Salmo salar): Lepeophtheirus salmonis and Caligus elongatus Dynamics over Four Consecutive Production Cycles

Journal of Marine Science and Engineering
Acoustic lice treatment (AcuLice) is a newly developed system which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar).

Effects of salmon lice infection on the behaviour of sea trout in the marine phase

Aquaculture Environment Interactions, 2014
Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Toward a model-based prediction system for salmon lice infestation pressure

Aquaculture Environment Interactions, 2016
High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary.

Interacting Effects of Sea Louse (Lepeophtheirus salmonis) Infection and Formalin-Killed Aeromonas salmonicida on Atlantic Salmon Skin Transcriptome

Frontiers in Immunology, 2022
Lepeophtheirus salmonis (sea lice) and bacterial co-infection threatens wild and farmed Atlantic salmon performance and welfare. In the present study, pre-adult L.

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...
