    Influence of body condition on the population dynamics of Atlantic salmon with consideration of the potential impact of sea lice.
    J Fish Dis 2017 Nov 21. Epub 2017 Nov 21.
    Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, UK.
    Atlantic salmon Salmo salar is an iconic species of high conservation and economic importance. At sea, individuals typically are subject to sea lice infestation, which can have detrimental effects on their host. Over recent decades, the body condition and marine survival in NE Atlantic stocks have generally decreased, reflected in fewer adults returning to rivers, which is partly attributable to sea lice.

    Sea trout adapt their migratory behaviour in response to high salmon lice concentrations.
    J Fish Dis 2017 Nov 21. Epub 2017 Nov 21.
    Norwegian Institute for Nature Research (NINA), Trondheim, Norway.
    Sea trout face growth-mortality trade-offs when entering the sea to feed. Salmon lice epizootics resulting from aquaculture have shifted these trade-offs, as salmon lice might both increase mortality and reduce growth of sea trout. We studied mortality and behavioural adaptations of wild sea trout in a large-scale experiment with acoustic telemetry in an aquaculture intensive area that was fallowed (emptied of fish) synchronically biannually, creating large variations in salmon lice concentrations.

    Horizontal and vertical distribution of sea lice larvae (Lepeophtheirus salmonis) in and around salmon farms in the Bay of Fundy, Canada.
    J Fish Dis 2017 Nov 21. Epub 2017 Nov 21.
    Cooke Aquaculture Inc., Back Bay, NB, Canada.
    The sea louse, Lepeophtheirus salmonis, is parasitic to salmonid species in the Northern Hemisphere and has become a widespread biological and economic problem for the salmon farming industry. A better understanding is needed of their spatial distribution and early life history to disrupt the life cycle of the sea louse. In this study, sea lice larval densities within salmon farms, between salmon farms and reference sites, and at various depths were quantified using both plankton pumps and plankton nets. Read More

    An overview of cleaner fish use in Ireland.
    J Fish Dis 2017 Nov 21. Epub 2017 Nov 21.
    Carna Research Station, Ryan Institute, National University of Ireland, Galway, Carna, Co. Galway, Ireland.
    Sea lice infestations represent one of the most significant challenges facing the salmon farming industry, giving rise to lost production, additional costs of treatment and potential negative interactions with wild stocks. At present, cleaner fish, which actively remove lice from salmon, are an effective, biological, long-term option which has been adopted by many countries. In Ireland, several key studies were conducted in the 1990s on the use of wild-caught wrasse (corkwing, goldsinny and rock cook) as cleaner fish in experimental and commercial scale trials.

    Invest more and die faster: The life history of a parasite on intensive farms.
    Evol Appl 2017 Oct 21;10(9):890-896. Epub 2017 Jun 21.
    Department of BiologyUniversity of BergenBergenNorway.
    Organisms are expected to respond to alterations in their survival by evolutionary changes in their life history traits. As agriculture and aquaculture have become increasingly intensive in the past decades, there has been growing interest in their evolutionary effects on the life histories of agri- and aquacultural pests, parasites, and pathogens. In this study, we used salmon lice (Lepeophtheirus salmonis) to explore how modern farming might have affected life history evolution in parasites. Read More

    A pedigree-based experiment reveals variation in salinity and thermal tolerance in the salmon louse, Lepeophtheirus salmonis.
    Evol Appl 2017 Dec 16;10(10):1007-1019. Epub 2017 Aug 16.
    Institute of Marine ResearchBergenNorway.
    The salmon louse is a highly abundant ectoparasitic copepod of salmonids in the North Pacific and Atlantic. Widespread and rapid development of resistance to chemical agents used to delouse salmonids on marine farms is now threatening the continued development of the aquaculture industry and have served as a potent catalyst for the development of alternative pest management strategies. These include freshwater and warm-water treatments to which the louse is sensitive. Read More

    Statistical modelling of sea lice count data from salmon farms in the Faroe Islands.
    J Fish Dis 2017 Nov 17. Epub 2017 Nov 17.
    Faculty of Science and Technology, University of the Faroe Islands, Nóatún 3, FO-100 Tórshavn, Faroe Islands & Fiskaaling - Aquaculture Research Station of the Faroes, Við Áir 11, FO-430, Hvalvík, Faroe Islands.
    Fiskaaling regularly counts the number of sea lice in the attached development stages (chalimus, mobiles and adult) for the salmon farms in the Faroe Islands. A statistical model of the data is developed. In the model, the sea-lice infection is represented by the chalimus (or mobile) lice developing into adult lice and is used to simulate past and current levels of adult lice-including treatments-as well as to predict the adult sea lice level 1-2 months into the future.

    The parasitic salmon louse, and its resistance to chemical delousing agents, represents one of the largest challenges to the salmon aquaculture industry. We genotyped lice sampled from wild salmon and sea trout throughout Norway with the recently identified Phe362Tyr mutation that conveys resistance to organophosphates. These results were compared to data from lice sampled on farmed salmon in the same regions. Read More

    Mitochondrial phylogenomics and genome rearrangements in the barklice (Insecta: Psocodea).
    Mol Phylogenet Evol 2017 Oct 24;119:118-127. Epub 2017 Oct 24.
    Department of Entomology, Purdue University, West Lafayette, IN 47907, USA.
    The mitochondrial genome arrangement in the insect order Psocodea (booklice, barklice, and parasitic lice) is extremely variable. Genome organization ranges from the rearrangement of a few tRNAs and protein coding genes, through extensive tRNA and protein coding gene rearrangements, to subdivision into multiple mini-chromosomes. Evolution of the extremely modified mitochondrial genome in parasitic lice (Phthiraptera) has been the subject of several studies, but limited information is available regarding the mitochondrial genome organization of the more plesiomorphic, free-living Psocodea (formerly known as the "Psocoptera").

    RNAi-mediated treatment of two vertically transmitted rhabdovirus infecting the salmon louse (Lepeophtheirus salmonis).
    Sci Rep 2017 Oct 25;7(1):14030. Epub 2017 Oct 25.
    SLCR-Sea Lice Research Centre, Department of Biology, University of Bergen, Thormøhlensgt. 55, Pb. 7803, NO-5020, Bergen, Norway.
    Rhabdoviruses are a family of enveloped negative-sense single-stranded RNA viruses infecting a variety of hosts. Recently, two vertically transmitted salmon louse (Lepeophtheirus salmonis) rhabdoviruses (LsRV) have been identified. The prevalence of these viruses was measured along the Norwegian coast and found to be close to 100%, and with the present lack of suitable cell lines to propagate these viruses, it is challenging to obtain material to study their host impact and infection routes.

    Short-Term Effects of the Anti-sea Lice Therapeutant Emamectin Benzoate on Clam Worms (Nereis virens).
    Arch Environ Contam Toxicol 2017 Oct 20. Epub 2017 Oct 20.
    Burridge Consulting Inc., 61 Emmalee Drive, Stratford, PE, C1B 0B5, Canada.
    The polychaete Nereis virens occurs commonly in marine sediments, is widely distributed, and is a popular bait species, as well as a potential replacement for wild-caught fish in commercial fish feed preparations. It is being considered as a potential co-extractive species for culture in integrated multi-trophic aquaculture operations. However, it is not known whether pesticides or drugs used to treat sea lice on farmed salmon, such as emamectin benzoate (EB), would adversely affect cultured or wild worms, because these compounds may persist in the environment.

    aNeurophysiology Laboratory, Physiology Unit, Department of Biomedicine, Medical School, Universitat de Barcelona, Barcelona, Spain bInstitute of Neurosciences, University of Barcelona, Barcelona, Spain cInstitut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), Barcelona, Spain dDpto. Biología de Sistemas, Edificio de Medicina Universidad de Alcalá, Alcalá de Henares, Madrid, Spain.
    Pyrethroid insecticides are widely used for pest control in agriculture or in human public health commonly as a topical treatment for scabies and head lice. Exposure to pyrethroids such as permethrin or tetramethrin (TM) causes sensory alterations such as transient pain, burning, stinging sensations, and paraesthesias. Despite the well-known effects of pyrethroids on sodium channels, actions on other channels that control sensory neuron excitability are less studied. Read More

    Detection of bacterial pathogens including potential new species in human head lice from Mali.
    PLoS One 2017 20;12(9):e0184621. Epub 2017 Sep 20.
    Aix Marseille Univ, CNRS, IRD, INSERM, AP-HM, URMITE, IHU - Méditerranée Infection, Marseille, France.
    In poor African countries, where no medical and biological facilities are available, the identification of potential emerging pathogens of concern at an early stage is challenging. Head lice, Pediculus humanus capitis, have a short life, feed only on human blood and do not transmit pathogens to their progeny. They are, therefore, a perfect tool for the xenodiagnosis of current or recent human infection. Read More

    Susceptibility, behaviour, and retention of the parasitic salmon louse (Lepeophtheirus salmonis) differ with Atlantic salmon population origin.
    J Fish Dis 2017 Sep 17. Epub 2017 Sep 17.
    Institute of Marine Research, Bergen, Norway.
    Atlantic salmon populations across the world have diverse ecological and evolutionary histories, from wild anadromous or landlocked, to domestication and genetic modification. The natural host behaviours confer protection from infestation by ectoparasitic salmon lice Lepeophtheirus salmonis, yet whether genetic origin results in different behaviours and thus susceptibility to infestation is unknown. In common garden experiments, we tested antiparasite behaviours, susceptibility and retention of salmon lice in wild anadromous, wild landlocked, domesticated and genetically modified domesticated strains.

    Behavioural responses of infective-stage copepodids of the salmon louse (Lepeophtheirus salmonis, Copepoda:Caligidae) to host-related sensory cues.
    J Fish Dis 2017 Sep 17. Epub 2017 Sep 17.
    Institute of Marine Research, Austevoll Research Station, Storebø, Norway.
    The salmon louse (Lepeophtheirus salmonis [Krøyer]) is an ectoparasitic copepod that causes disease in farmed Atlantic salmon (Salmo salar) and may play a role in the decline of some wild salmonid populations. Controlling lice infestations is a major cost for the salmon industry; this has stimulated the pursuit of alternative approaches to controlling them. One such approach involves determining, and then disrupting, the sensory cues used by the parasite to find its host. Read More

    Departamento de Microbiologia e Parasitologia, Programa de Pós-graduação em Parasitologia, Instituto de Biologia, Universidade Federal de Pelotas, Capão do Leão, Rio Grande do Sul, Brazil.
    Parasites may influence host fitness and consequently exert a selective pressure on distinct phenotypes of the host population. This pressure can result in an evolutionary response, maintaining only individuals with certain traits in the population. The present study was aimed at identifying the morphological characteristics of juveniles and adults of Columba livia that may influence the distribution patterns of lice, Pseudolynchia canariensis and Haemoproteus columbae and how the populations of these parasites vary throughout the seasons of the year.

    The present study was aimed to evaluate the factors associated with prevalence of various ectoparasites among goats during winter season in two different agro-climatic regions of India. A total of 320 goats (Uttarakhand-208; Uttar Pradesh-112) were screened and evaluated for ectoparasitism and associated factors. The occurrence of ectoparasitism in goats was studied in relation with age, sex, breed, housing, agro-climatic region and system of rearing. Read More

    Background: Microsporidia are highly specialized, parasitic fungi that infect a wide range of eukaryotic hosts from all major taxa. Infections cause a variety of damaging effects on host physiology from increased stress to death. The microsporidian Facilispora margolisi infects the Pacific salmon louse (Lepeophtheirus salmonis oncorhynchi), an economically and ecologically important ectoparasitic copepod that can impact wild and cultured salmonids.
