Pathogens From Salmon Aquaculture in Relation to Conservation of Wild Pacific Salmon in Canada: An Alternative Perspective

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Several articles over the last two decades have provided data, analyses and interpretations that suggest there are significant impacts of pathogens transmitted from farmed salmon on wild Pacific salmon populations in British Columbia (BC), the westernmost province of Canada.

Gene expression in five salmon louse (Lepeophtheirus salmonis, Krøyer 1837) tissues

Marine Genomics, 2014
The Atlantic salmon, Salmo salar L, is an important species both for traditional fishery and fish farming. Many Atlantic salmon stocks have been declining and a suspected main contributor to this decline is the salmon louse (Lepeophtheirus salmonis); a parasitic copepod living off the salmonid hosts epidermal tissues and blood.

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

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Salmon louse (Lepeophtheirus salmonis) infestations significantly impair the survival of sea‐run brown trout (Salmo trutta), with a 73% reduction in survival probability per louse per gram of fish weight in 2020 and a 58% reduction in 2021. Our findings provide clear evidence of the long‐term ecological impacts of parasite burdens and underscore the ...

What are the effects of sea lice on wild and farmed Pacific and Atlantic salmon? A systematic map protocol

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
This protocol sets out the research methodologies for a systematic map to identify, collate and describe the information that exists on the effects of sea lice from net‐pen salmon farms on wild, enhanced or farmed Pacific (i.e. Chinook, coho, chum, sockeye or pink salmon) and Atlantic salmon globally. The results will help guide further exploration and

Use of lumpfish for sea-lice control in salmon farming: challenges and opportunities [PDF]

, 2017
Efficient sea-lice control remains one of the most important challenges for the salmon farming industry. The use of wrasse (Labridae) as cleaner fish offers an alternative to medicines for sea-lice control, but wrasse tend to become inactive in winter ...

How to Reproduce in the Siberian Winter: Proteome Dynamics Reveals the Timing of Reproduction‐Related Processes in an Amphipod Species Endemic to Lake Baikal

Ecology and Evolution, Volume 15, Issue 7, July 2025.
The vast Lake Baikal in Siberia is located in a region with a continental climate, implying pronounced seasonal temperature differences. Remarkably, reproducing during the extremely cold winters when the lake is covered by a thick ice layer is a common trait in Baikal's endemic littoral amphipods.

Impact of thermoclines on the vertical distribution of salmon lice larvae

Aquaculture Environment Interactions, 2020
Salmon louse Lepeophtheirus salmonis, a key parasite of salmonids, is managed by multiple methods at both salmon farm- and ecosystem-scale that are informed by an understanding of the abundance and distribution of the infective, planktonic stage of the ...

Dispersal and Gene Flow Among Potential Spawners: Source–Sink Structure Among Populations of Anadromous Brown Trout Exposed to Multifaceted Anthropogenic Impacts

Evolutionary Applications, Volume 18, Issue 7, July 2025.
ABSTRACT Dispersal impacts individual fitness and influences local dynamics, stability and adaptation in interconnected populations. Anadromous salmonid fishes are renowned for their precise homing and adaptations to local aquatic environments, while navigating between multiple connected habitats.

Phylogenetic Diversity and Geographic Distribution of Atlantic Salmon Calicivirus in Major Salmon Farming Regions

Journal of Fish Diseases, Volume 48, Issue 6, June 2025.
ABSTRACT Salovirus is a genus within the family Caliciviridae, which contains a single member species, Salovirus nordlandense, also known as Atlantic salmon calicivirus (ASCV). While previous work has shown that ASCV can replicate in fish cell lines and establish systemic infection in vivo, its exact role in disease remains unclear and very little is ...
