The planktonic stages of the salmon louse (Lepeophtheirus salmonis) are tolerant of end-of-century pCO2 concentrations [PDF]

PeerJ, 2019
The copepod Lepeophtheirus salmonis is an obligate ectoparasite of salmonids. Salmon lice are major pests in salmon aquaculture and due to its economic impact Lepeophtheirus salmonis is one of the most well studied species of marine parasite.

Microbial communities associated with the parasitic copepod Lepeophtheirus salmonis [PDF]

Marine Genomics, 2020
Abstract Lepeophtheirus salmonis is a naturally occurring marine parasite of salmonid fishes in the Northern hemisphere, and a major problem in salmonid aquaculture. In addition to the direct effects on host fish, L. salmonis may act as a vector for diseases. Here, the microbial community of L.

Behaviour and Dispersal of Mobile Salmon Lice When Detached From the Host. [PDF]

J Fish Dis
ABSTRACT Sea lice can flourish when salmon are farmed in open sea‐cages, necessitating treatments to control outbreaks and reduce larval export. However, mobile ectoparasitic stages can be dislodged during crowding or other procedures, and potentially reinfest farmed or wild fish.

Parasitic copepods (Crustacea, Hexanauplia) on fishes from the lagoon flats of Palmyra Atoll, Central Pacific [PDF]

ZooKeys, 2019
We surveyed copepods parasitic on the fishes at Palmyra, a remote atoll in the Central Indo-Pacific faunal region. In total, we collected 849 individual fish, representing 44 species, from the intertidal lagoon flats at Palmyra and recovered 17 parasitic

Light and scanning electron microscopic studies of Lepeophtheirus salmonis (Siphonostomatoida: Caligidae) infecting the rosy goatfish Parupeneus rubescens

Journal of Asia-Pacific Biodiversity, 2020
Parasites, particularly crustaceans, are considered as an important limiting factor in the development of intensified fish culture. The parasitic copepod of the Arabian Gulf fish is poorly known.

The salmon louse genome may be much larger than sequencing suggests

Scientific Reports, 2022
The genome size of organisms impacts their evolution and biology and is often assumed to be characteristic of a species. Here we present the first published estimates of genome size of the ecologically and economically important ectoparasite ...

Predicting the abundance of Lepeophtheirus salmonis in the Bay of Fundy, New Brunswick. [PDF]

J Aquat Anim Health
Abstract Objective The primary objective was to construct a time series model for the abundance of the adult female (AF) sea lice Lepeophtheirus salmonis in Atlantic Salmon Salmo salar farms in the Bay of Fundy, New Brunswick, Canada, for the period 2016–2021 and to illustrate its short-term ...

Losing the ‘arms race’: multiresistant salmon lice are dispersed throughout the North Atlantic Ocean

Royal Society Open Science, 2021
Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in our favour.

Salmon Louse Infestation Impairs the Long-Term Survival of Sea-Run Brown Trout. [PDF]

Ecol Evol
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 ...

Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2 synthases in physiology and host–parasite interactions

Parasites & Vectors, 2021
Background The salmon louse (Lepeophtheirus salmonis) is a parasite of salmonid fish. Atlantic salmon (Salmo salar) exhibit only a limited and ineffective immune response when infested with this parasite.
