A partly stage-structured model for the abundance of salmon lice in salmonid farms

Epidemics, 2019
The parasitic salmon louse constrains growth in the Norwegian salmon farming industry through density dependent host-parasite interaction. Hence, there is a need for insight into how increases in salmon production, varying spatial organisation of the ...

Assessment of Salinity Tolerance in Lepeophtheirus salmonis Following Five Generations of Freshwater Treatment Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...

The use of a general linear model to identify epidemiological factors affecting the abundance of chalimus stages of the sea louse (Lepeophtheirus salmonis) on Scottish salmon farms [PDF]

, 2003
In this communication chalimus lice numbers in the second, third and fourth quarters of the production cycle are examined in relation to a range of prevailing risk factors using an approach based on that already taken for mobile stages (Revie et al.

Effect of ectoparasite infestation density and life‑history stages on the swimming performance of Atlantic salmon Salmo salar

Aquaculture Environment Interactions, 2016
To overcome sustainability obstacles and improve operations, the Atlantic salmon farming industry is testing novel approaches to production. Redistributing farm sites to offshore locations is one such solution; however, tolerance to high-current velocity

Divergent Healing Trajectories Among Common Mechanical Skin Wound Types in Post‐Smolt Atlantic Salmon (Salmo salar Linnaeus, 1758)

Journal of Fish Diseases, EarlyView.
ABSTRACT Mechanical wounds are a common form of skin damage in Atlantic salmon (Salmo salar Linnaeus, 1758) aquaculture and can predispose fish to secondary infections. Such wounds often arise from routine farming practices, including delousing operations.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Towards a better understanding of the evacuation time of salmon lice (Lepeophtheirus salmonis) in lumpfish (Cyclopterus lumpus)

Aquaculture Reports
Cleaner fish are utilised as a preventive control measure against sea lice infestations in salmon farms. In recent years, lumpfish (Cyclopterus lumpus) has been the most commonly deployed cleaner fish species in Norway.

Impact of variable physical conditions and future increased aquaculture production on lice infestation pressure and its sustainability in Norway

Aquaculture Environment Interactions, 2020
Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway.

Predation Risk and Depth Use During Migration of Atlantic Salmon Smolts Through a Fjord Impacted by Hydropower Discharge

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Atlantic salmon (Salmo must survive the transition from river to fjord in order to migrate to northern latitudes where they feed and grow at sea. In the River Suldalslågen in southern Norway, hydropower regulated water discharge determines the timing and extent of river flows and fjord currents.

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...
