The Disease Burden in Fish Farm Management: An Integrative View and a Specific Vision in Europe

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT In aquaculture, the interactions and balance—or imbalance—between the fish, the rearing environment, pathogens, and farm management determine the occurrence and impact of clinical diseases. The global assessment of the factors related to disease impact is commonly referred to as disease burden.

Optimization of calcium oxide treatment against salmon louse (Lepeophtheirus salmonis). A controlled laboratory study

Aquaculture Reports
Salmon louse (Lepeophtheirus salmonis) infestations pose a significant challenge to the salmonid farming industry. While most conventional water-treatment protocols primarily target lice at parasitic stages once attached to the fish, preventive measures ...

Revisiting Vitamin and Trace Mineral Nutrition in Atlantic Salmon Farming With Emphasis on Fish Health

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Atlantic salmon farming is faced with numerous environmental and production‐related challenges affecting fish health and welfare, globally and in Norway. An animal's requirement for a nutrient is the sum of the required supply of available nutrients for maintenance, growth, reproduction, health, and disease resistance.

Effects of chitin synthesis inhibitor treatment on Lepeophtheirus salmonis (Copepoda, Caligidae) larvae.

PLoS ONE, 2019
The salmon louse (Lepeophtheirus salmonis) is an ectoparasite infecting Atlantic salmon (Salmo salar), which causes substantial problems to the salmon aquaculture and threatens wild salmon.

Sea Lice (Lepeophtheirus salmonis) Infestation Reduces the Ability of Peripheral Blood Monocytic Cells (PBMCs) to Respond to and Control Replication of Salmonid Alphavirus in Atlantic Salmon (Salmo salar L.)

Viruses, 2020
Here we have studied the impact of lice (Lepeophtheirus salmonis) infestation of donor fish on the ability of isolated peripheral blood monocytes (PBMCs) to control the replication of salmonid alphavirus (SAV) ex vivo.

Local and systemic gene expression responses of Atlantic salmon (Salmo salar L.) to infection with the salmon louse (Lepeophtheirus salmonis) [PDF]

, 2008
Background The salmon louse (SL) is an ectoparasitic caligid crustacean infecting salmonid fishes in the marine environment. SL represents one of the major challenges for farming of salmonids, and veterinary intervention is necessary to combat infection.

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.

Inventory and comparison of abundance of parasitic copepods on fish hosts in the western Wadden Sea (North Sea) between 1968 and 2010 [PDF]

A conspicuous part of the parasite fauna of marine fish are ectoparasites, which attach mainly to the fins or gills. The abundant copepods have received much interest due to their negative effects on hosts.

Sequence variation in four mitochondrial genes of the salmon louse Lepeophtheirus salmonis [PDF]

Diseases of Aquatic Organisms, 2006
A total of 210 Lepeophtheirus salmonis collected from 7 locations (Scotland, Russia, Canada, Japan and 3 locations in Norway), were screened for sequence variation in 4 mitochondrial genes; ATPase subunit 6 (A6), Cytochrome b oxidase subunit I (COI), Cytochrome b (Cyt b) and 16S rRNA.

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
