Major vault protein is part of an extracellular cement material in the Atlantic salmon louse (Lepeophtheirus salmonis)

Scientific Reports
Major vault protein (MVP) is the main component of the vault complex, which is a highly conserved ribonucleoprotein complex found in most eukaryotic organisms.

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.

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.

Relationship of farm salmon, sea lice, and wild salmon populations [PDF]

Proceedings of the National Academy of Sciences, 2010
Increased farm salmon production has heightened concerns about the association between disease on farm and wild fish. The controversy is particularly evident in the Broughton Archipelago of Western Canada, where a high prevalence of sea lice (ectoparasitic copepods) was first reported on juvenile wild pink salmon (Oncorhynchus gorbuscha) in 2001 ...

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 ...

Making the best of lousy circumstances: the impact of salmon louse Lepeophtheirus salmonis on depth preference of sea trout Salmo trutta

Aquaculture Environment Interactions, 2020
Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. However, the effect of natural haloclines in fjords on parasite dynamics is not well understood.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Bath Treatments With Emamectin Benzoate Control Dactylogyrideans Infecting Colossoma macropomum Gills Without Altering Physiology of This Host Fish

Journal of Fish Diseases, EarlyView.
ABSTRACT Intensification of fish aquaculture worldwide has led to severe problems of diseases caused by parasitic dactylogyrideans. In this study, the anti‐dactylogyridean efficacy of treating Colossoma macropomum with baths of emamectin benzoate (EMB) was investigated for the first time, along with the effects of this treatment on the haematology and ...

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

Journal of Fish Diseases, EarlyView.
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.

The use of epidemiology for evaluating the performance and administration strategies of topical drugs for controlling sea lice in Chile

, 2015
Sea lice is considered the most important ectoparasite that affects salt water farmed salmonids around the world. Its high economic impact has motivated efforts for its control.
