Mechanism behind Resistance against the Organophosphate Azamethiphos in Salmon Lice (Lepeophtheirus salmonis). [PDF]

PLoS ONE, 2015
Acetylcholinesterase (AChE) is the primary target for organophosphates (OP). Several mutations have been reported in AChE to be associated with the reduced sensitivity against OP in various arthropods.

Principles and Methods of Counteracting Harmful Salmon–Arthropod Interactions in Salmon Farming: Addressing Possibilities, Limitations, and Future Options

Frontiers in Marine Science, 2021
The arthropod salmon louse (Lepeophtheirus salmonis) is a major threat to Atlantic salmon aquaculture and wild salmonids. Essentially like in monoculture, very high concentrations of susceptible hosts may result in high reproduction and severe production

Surveillance of the Sensitivity towards Antiparasitic Bath-Treatments in the Salmon Louse (Lepeophtheirus salmonis). [PDF]

PLoS ONE, 2016
The evolution of drug resistant parasitic sea lice is of major concern to the salmon farming industry worldwide and challenges sustainable growth of this enterprise. To assess current status and development of L.

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.

Sea Lice (Lepeophtheirus salmonis) Harbour Putative Fish Pathogens: Insights From Illumina and Nanopore Sequencing

Journal of Fish Diseases, EarlyView.
ABSTRACT Ectoparasites that penetrate host skin can act as biological or mechanical vectors for pathogens and, in some cases, serve as reservoirs. Crustacean ectoparasites of fish are potential vectors of pathogens, which is especially relevant for obligate pathogens (e.g., Aeromonas salmonicida) with limited seawater survival. Sea lice (Lepeophtheirus

Gene Expression Response to Sea Lice in Atlantic Salmon Skin: RNA Sequencing Comparison Between Resistant and Susceptible Animals [PDF]

, 2018
Sea lice are parasitic copepods that cause large economic losses to salmon aquaculture worldwide. Frequent chemotherapeutic treatments are typically required to control this parasite, and alternative measures such as breeding for improved host resistance

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

Journal of Fish Diseases, EarlyView.
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 ...

Parasitic sea louse infestations on wild sea trout: separating the roles of fish farms and temperature

Parasites & Vectors, 2018
Background The causal relation between parasitic sea lice on fish farms and sea lice on wild fish is a controversial subject. A specific scientific debate has been whether the statistical association between infestation pressure (IP) from fish farms and ...

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 ...
