Delrieu-trottin, Erwan; Williams, Jeffrey T.; Pitassy, Diane; Driskell, Amy; Hubert, Nicolas; Viviani, Jeremie; Cribb, Thomas H.; Espiau, Benoit; Galzin, Rene; Kulbicki, Michel; De Loma, Thierry Lison; Meyer, Christopher; Mourier, Johann; Mou-tham, Gerard; Parravicini, Valeriano; Plantard, Patrick; Sasal, Pierre; Siu, Gilles; Tolou, Nathalie; Veuille, Michel; Weigt, Lee; Planes, Serge.
The emergence of DNA barcoding and metabarcoding opened new ways to study biological diversity, however, the completion of DNA barcode libraries is fundamental for such approaches to succeed. This dataset is a DNA barcode reference library (fragment of Cytochrome Oxydase I gene) for 2,190 specimens representing at least 540 species of shore fishes collected over 10 years at 154 sites across the four volcanic archipelagos of French Polynesia; the Austral, Gambier, Marquesas and Society Islands, a 5,000,000 km(2) area. At present, 65% of the known shore fish species of these archipelagoes possess a DNA barcode associated with preserved, photographed, tissue sampled and cataloged specimens, and extensive collection locality data. This dataset represents one...

Digenean metacercariae parasites as natural tags of habitat use by 0-group common sole Solea solea in nearshore coastal areas: A case study in the embayed system of the Pertuis Charentais (Bay of Biscay, France) ArchiMer
Durieux, Eric; Begout, Marie-laure; Pinet, Patrick; Sasal, Pierre.
This study focused on the spatio-temporal variation in the host-parasite system, 0-group sole-digenean metacercariae, in nearshore coastal areas at relatively small spatial scale. 0-group soles were sampled using a standard beam trawl in April, May, June, August and October 2005 at nine different sites in the Pertuis Charentais area (Bay of Biscay, France). Sole density, size, Fulton's condition factor K and digenean metacercariae communities were analysed. 0-group sole concentrated in shallow and muddy areas where they accumulated digenean metacercariae. Parasite communities displayed strong spatial patterns tightly linked to the distribution of the first intermediate mollusc hosts. These parasitological data suggest that 0-group sole during their first...

Effects of local Polynesian plants and algae on growth and expression of two immune-related genes in orbicular batfish (Platax orbicularis) ArchiMer
Reverter, Miriam; Saulnier, Denis; David, Rarahu; Bardon-albaret, Agnes; Belliard, Corinne; Tapissier-bontemps, Nathalie; Lecchini, David; Sasal, Pierre.
The emerging orbicular batfish (Platax orbicularis) aquaculture is the most important fish aquaculture industry in French Polynesia. However, bacterial infections are causing severe mortality episodes. Therefore, there is an urgent need to find an effective management solution. Besides the supplying difficulty and high costs of veterinary drugs in French Polynesia, batfish aquaculture takes place close to the coral reef, where use of synthetic persistent drugs should be restricted. Medicinal plants and bioactive algae are emerging as a cheaper and more sustainable alternative to chemical drugs. We have studied the effect of local Polynesian plants and the local opportunistic algae Asparagopsis taxiformis on batfish when orally administered. Weight gain and...

Sedentary behaviour establishment in 0-group common sole Solea solea: a laboratory video-tracking study ArchiMer
Durieux, Eric; Le Duigou, Mathieu; Millot, Sandie; Sasal, Pierre; Begout, Marie-laure.
Spontaneous swimming activity of 0-group common sole (Solea solea) was evaluated using a video-tracking system under laboratory conditions. An experiment was conducted during two consecutive days on individuals sampled in June, July, September and November (2004) in a coastal nursery ground (Pertuis Charentais, Bay of Biscay, France). The measured behavioural variables were: distance travelled and frequency of occurrence of burying, swimming and immobility. 0-group sole showed a relatively clear circadian activity in line with the artificial light conditions (day, twilight and night). Swimming activity of 0-group sole decreased drastically from June to July, thereafter remaining at a very low level in September and November. Such important changes reflect...

Silver European eels health in Mediterranean habitats ArchiMer
Amilhat, Elsa; Fazio, Geraldine; Simon, Gael; Manetti, Marc; Paris, Severine; Delahaut, Laurence; Farrugio, Henri; Lecomte-finiger, Raymonde; Sasal, Pierre; Faliex, Elisabeth.
The degradation in the quality of silver eel and their health could have been a major factor in the collapse of the European eel (Anguilla anguilla) population. However, the health status of the spawners has been poorly studied until now. This study evaluated the quality of migrant male silver eels from four Mediterranean habitats in France presenting different degrees of contamination: Canet-Saint-Nazaire, Salses-Leucate and Bages-Sigean lagoons and La Berre River. We considered pathogens including Anguillicoloides crassus and EVEX virus and the concentration of chemical contaminants including PCBs, OCs and heavy metals. Our study results revealed different patterns of pollution and infection in the four habitats, with high individual variability. No...

Spatial variability in digenean metacercariae infection of 0-group common sole Solea solea among nurseries along the French Atlantic coast ArchiMer
Durieux, Eric; Begout, Marie-laure; Sasal, Pierre.
We sampled 0-group sole juveniles (N = 174) in September and October 2003 in 9 major nurseries located along the French Atlantic coast (English Channel and Bay of Biscay). 0-group sole were infected with 3 genera of digenean metacercariae, Timoniella spp. (Acanthostomidae), Prosorhynchus crucibulum and Prosorhynchus sp. A (Bucephalidae), Podocotyle sp. (Opecoelidae), and an unidentified species of Digenea. Parasite infection levels in the English Channel nurseries were lower, and the community composition was different from Bay of Biscay nurseries. We hypothesize that the difference between geographic areas was due to differences in first intermediate host communities and, to a lesser extent, because of lower temperatures in the English Channel compared to...

Temporal changes in lipid condition and parasitic infection by digenean metacercariae of young-of-year common sole Solea solea (L.) in an Atlantic nursery ground (Bay of Biscay, France) ArchiMer
Durieux, Eric; Galois, Robert; Begout, Marie-laure; Sasal, Pierre; Lagardere, Francoise.
Little attention has been paid to flatfish parasitism as a potential factor of variation in year-class strength. The aim of this study was to evaluate the relationship between parasitic infection and nutritional condition of young-of-year (YOY) common sole. Sole were collected monthly from May (early settlement) to November 2004 in a mussel pole culture area, using a push-net or a trawl, and dissected for parasite identification and counts. Total lipids were extracted from the whole body and lipid classes quantified. Triacylglycerols to sterols (free form) ratio (TAG/ST) was used as an index of nutritional status. Digenean metacercariae infection, characterized by two dominant genera, displayed clear seasonal dynamics and the highest records yet reported...
