“…The present work also confirms the previous report of infection by Prosorhynchus spp. metacercariae in YOY sole in the Pertuis Breton (Laffargue et al, 2004) and precises that a majority of the metacercariae appeared to be P. crucibulum. The first intermediate host for…”

“…This result agrees with the timing of infection reported by Coustau et al (1990): sporocysts release well developed cercariae from mussels in June and July. However, Laffargue et al (2004) recorded much lower infection levels in YOY sole in the same nursery. Based on 65% prevalence and mean abundance of around 3 and 8 parasites per fish sampled in August and December respectively, but at a different site in each case, they concluded that there was an autumnal change.…”

“…Parasitic infection of juvenile sole by Prosorhynchus spp. (Digenea, Bucephalidae) metacercariae has recently been reported in the Pertuis Charentais (Laffargue et al, 2004). This area represents an important nursery ground for the common sole stock of the Bay of Biscay, both in terms of density and potential surface area (Le Pape et al, 2003b).…”

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 for sole. Prevalence (P%) and mean abundance (Ab ± SE) increased for Timoniella spp.

“…The anatomy of the adult worm Skrjabiniella aculeatus (Odhner), later renamed P. aculeatus [18] is well known, however, the life cycle of this parasite is yet little understood. It is known that a bivalve is the first intermediate host in the marine environment, and the definitive host of P. crucibulum and P. aculeatus parasites is Conger conger [8,21,22].…”

The cercariae stages of Prosorhynchus crucibulum and Prosorhynchus aculeatus are morphologically indistinguishable. However, the differentiation of these two species is crucial to understand the transmission dynamics between these primary hosts (mussels) and the secondary hosts (fish). In this way, the objective of this study is to develop an accurate molecular identification tool to differentiate the cercariae stage of P. crucibulum and P. aculeatus. We targeted the 18S nuclear ribosomal DNA region by PCR amplification and sequenced this amplicon. By generating these sequences, we developed a RFLP tool with the use of the enzymes HincII and FokI that produced different restriction profiles between P. crucibulum and P. aculeatus. Each enzyme generated different-sized fragments specific to the species examined and no cross-reaction between the species was detected in their restriction pattern. By sequencing, no intraspecific-polymorphism was detected since there is 100% homology among P. aculeatus or P. crucibulum. These results indicate that PCR-linked restriction analysis of the 18S rDNA region provided us with rapid and reliable molecular tools for distinction of the cercariae of these species. The sequences generated were deposited in GenBank accession numbers for P. crucibulum cercariae (FJ463407, FJ463408 and FJ463409) and adult worm (FJ429096, FJ429097), and for P. aculeatus adult (FJ429094 and FJ429095).

“…Common sole Solea solea (Linnaeus, 1758) 0-group juveniles from the Pertuis Breton nursery ground on the French Atlantic coast are known to be infected by digenean metacer-cariae, including Prosorhynchus spp. (Bucephalidae) (Laffargue et al 2004, Durieux et al 2007). Durieux et al (2007) suggested that heavy infections levels as well as low nutritional status of these fish could lower winter survival.…”

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 the Bay of Biscay. For the Bay of Biscay nurseries, mean total parasite abundance was strongly negatively correlated with mean annual river flow. This relationship may be the result of the more upstream location of 0-group sole nurseries in estuaries so that fish were further from local points of parasite transmission than those in embayed nurseries. Digenean metacercariae load may be influenced by 3 major local factors, i.e. abundance and proximity of the first intermediate hosts and cercariae dispersal capacities.
