Modelling benthic invasion by the colonial gastropod Crepidula fornicata and its competition with the bivalve Pecten maximus . 2. Coupling the 0D model of colony-forming species to a connectivity matrix for a realistic distributed simulation of benthic invasion

The anthropogenic introduction in U.K. waters of the north-American marine gastropod Crepidula fornicata (Linné, 1758), commonly called slipper limpet, and its consecutive spreading has led in less than a century to the invasion of a part of benthic grounds along the North-European coasts. Competition for space has hampered the maintenance of the native scallop Pecten maximus, whereas dredge clogging has drastically limited scallop fishing, especially in the Western English Channel. In order to assess the possible future distribution and abundance of both species (Crepidula and Pecten), an original model of slipper limpet chains joined to a simple year-class model of the scallop (Ménesguen and Grégoris, 2017) has been coupled to a connectivity matrix...

Bilan du suivi de l'exploitation industrielle de la crépidule en Bretagne Nord (baies de Saint-Brieuc et du Mont Saint-Michel) 2002-2005
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Blanchard, Michel; Hamon, Dominique.
The slipper-limpet (Crepidula fornicata) is a marine gastropod which causes serious perturbations in shellfish beds, because of spatial spreading and density rising. Along French coasts, in Northern Brittany, two bays are highly colonized : bay of Saint-Brieuc, centre for scallops fishery, and bay of Mont-Saint-Michel, a famous oyster-farming area, with a total limpet stock about 450 000 metric tons. The association AREVAL was founded in 2001 to manage there, an industrial collect of limpets by a succing-dredge, followed ashore by a treatment for calcareous soil improvement. The scientific survey, contracted to IFREMER, included measurements of long andshort-term dredge's effects on grounds and limpet population, and proposals to set up dredging...

Spread of the slipper limpet Crepidula fornicata (L. 1758) in Europe. Current state dans consequences
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Blanchard, Michel.
The present distribution of the slipper limpet Crepidula fornicata in Europe is described in detail for each country, and an overview provided thanks to new information. Main observations of introduction and spread, obtained from the literature, are discussed. For most of them, we observe that both aspects are due to oyster harvesting and farming. ln the most heavily infested areas (France, England, the Netherlands), activities of dredging, harvesting and oyster farming have been disrupted. In France, these activities are so much hampered that treatment methods are now developed.

Cartographie et évaluation du stock de crépidules en baie du Mont Saint-Michel, en 2004
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Blanchard, Michel; Clabaut, Philippe; Abernot-le Gac, Chantal.
In 2003 and 2004, 3 cruises were organized using observations systems and sampling techniques to carry out cartography and stock assessment of the Slipper-limpet population (Crepidula fornicata) in the bay of Mont-Saint-Michel (Western Channel). This was done as part of the National Programme of Coastal Environment (Programme National d'Environnement Côtier - PNEC). The study helped to update previous data collected in 1995-96 with similar techniques : side-scan-sonar and submarine video for observation, and scuba diving and grabs for samples collection. Results show that during an eight years period, the limpet population spread in the southern part of the bay and that its stock rose about 50%, reaching about 150,000 metric tons, south of a...

Répartition et évaluation du stock de la crépidule (Crepidula fornicata), entre le cap Fréhel et le Mont Saint-Michel (Manche Ouest)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Blanchard, Michel.
This report deals with results obtained in 1995 and 1996 through a grant of Council of Brittany. The distribution and stock assessment of the slipper-limpet population (Crepidulafornicata) is analysed, in the near shoreline between Cap Fréhel and Mont-Saint-Michel. Several cruises allowed to use side-scan sonar, underwater video and scuba diving observations. Hamon grab has been used for quantitative sampling. Several direct observations were done ashore for complete informations. On this seaside of Brittany, it is observed that the population is mainly concentrated along the coast and main densities are found in the bay of Cancale, around deep oyster beds. Total fresh biomass is estimated about 149 000 metric tons. Local reasons and consequences of such a...
