The off-host survival and viability of a native and non-native fish louse (Argulus, Crustacea: Branchiura) [PDF]

Current Zoology, 2011
Abstract Fish ectoparasites are introduced to water bodies or aquaculture systems along with their hosts. Argulid fish lice can survive off-host for a given time, and in spite of quarantine measures might also be introduced via the transfer of water. However, they must cope with varying abiotic conditions without access to food.

Two apolipoproteins in salmon louse (Lepeophtheirus salmonis), apolipoprotein 1 knock down reduces reproductive capacity

Biochemistry and Biophysics Reports, 2021
The salmon louse, Lepeophtheirus salmonis is an ectoparasite of salmonid fish in the Northern Hemisphere, causing large economical losses in the aquaculture industry and represent a threat to wild populations of salmonids.

A novel approach to co-expression network analysis identifies modules and genes relevant for moulting and development in the Atlantic salmon louse (Lepeophtheirus salmonis)

BMC Genomics, 2021
Background The salmon louse (Lepeophtheirus salmonis) is an obligate ectoparasitic copepod living on Atlantic salmon and other salmonids in the marine environment.

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 ...

Population and Transcriptomic Changes of the Tropical Fish Parasite Caligus confusus (Copepoda: Caligidae) with Seasonal Variations in Sea Temperature

Fishes, 2023
Fish–parasite systems could be subject to two scenarios under climate change: (i) increased water temperature might enhance parasite metabolism, allowing the parasite to spread rapidly; (ii) parasitism could decrease if the optimal temperature for growth

Modeling parasite dynamics on farmed salmon for precautionary conservation management of wild salmon.

PLoS ONE, 2013
Conservation management of wild fish may include fish health management in sympatric populations of domesticated fish in aquaculture. We developed a mathematical model for the population dynamics of parasitic sea lice (Lepeophtheirus salmonis) on ...

Sea lice infestation level alters salmon swimming depth in sea-cages

Aquaculture Environment Interactions, 2016
Host-parasite systems are often characterised by a co-evolutionary arms race, with avoidance behaviour being the first line of defence for hosts. In aquatic ecosystems, the rapid rise of fish farming has elevated host abundance, altering the context of ...

Distribution of Fish Parasites Argulus japonicus and Argulus coregoni (Crustacea: Branchiura: Argulidae) in the Lake Biwa Basin, Central Japan

Species Diversity, 2023
Argulus japonicus Thiele, 1900 and Argulus coregoni Thorell, 1864 are ectoparasites of freshwater fishes and are known to occur in Lake Biwa and its adjacent inland waters in Shiga Prefecture, central Japan.

Quantitative risk assessment of salmon louse-induced mortality of seaward-migrating post-smolt Atlantic salmon

Epidemics, 2018
The Norwegian government recently implemented a new management system to regulate salmon farming in Norway, aiming to promote environmentally sustainable growth in the aquaculture industry.

Correlation between body size and fecundity in fish louse Argulus bengalensis Ramakrishna, 1951 (Crustacea: Branchiura) [PDF]

Journal of Parasitic Diseases, 2012
The life history traits like fecundity and body size are useful predictors of life history strategies of organisms. The information on these aspects provided necessary input for control measures for ectoparasites. In view of this, the variations in the life history traits of the fish louse Argulus bengalensis Ramakrishna (1951) were assessed using age ...
