Space-time modelling of the spread of salmon lice between and within Norwegian marine salmon farms. [PDF]

PLoS ONE, 2013
Parasitic salmon lice are potentially harmful to salmonid hosts and farm produced lice pose a threat to wild salmonids. To control salmon lice infections in Norwegian salmonid farming, numbers of lice are regularly counted and lice abundance is reported ...

Salmon louse labial gland enzymes: implications for host settlement and immune modulation

Frontiers in Genetics
Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin.

Phenylalanine Hydroxylase RNAi Knockdown Negatively Affects Larval Development, Molting and Swimming Performance of Salmon Lice

Frontiers in Marine Science, 2020
Phenylalanine hydroxylase (PAH) is a crucial enzyme involved in tyrosine biosynthesis, having roles in neurological and physiological processes. The purpose of PAH has received little attention in crustaceans despite extensive investigations in other ...

Evidence that head and body lice on homeless persons have the same genotype. [PDF]

PLoS ONE, 2012
Human head lice and body lice are morphologically and biologically similar but have distinct ecologies. They were shown to have almost the same basic genetic content (one gene is absent in head lice), but differentially express certain genes, presumably ...

Salmon lice loads on Atlantic salmon smolts associated with reduced welfare and increased population mortalities

Aquaculture Environment Interactions, 2023
Modelling potential impacts of salmon lice Lepeophtheirus salmonis on Atlantic salmon Salmo salar requires estimation of the levels that cause serious sub-lethal physiological impacts and direct mortality.

Molecular identification of head lice collected in Franceville (Gabon) and their associated bacteria

Parasites & Vectors, 2020
Background Pediculus humanus , which includes two ecotypes (body and head lice), is an obligate bloodsucking parasite that co-evolved with their human hosts over thousands of years, thus providing a valuable source of information to reconstruct the human

Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics

Journal of Marine Science and Engineering, 2022
Acoustic lice treatment (AcuLice) is a newly developed system, which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar).
