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...

Cartographie et évaluation des principaux mollusques filtreurs du Golfe Normano-Breton
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Noel, Philippe; Blanchard, Michel; Berthou, Patrick.
During 1993 and 1994, quantitative sampling were realized in Norman Gulf (Western Channel) to estimate molluscs suspension-feeders. Four bivalves are regularly sampled : Spisula ovalis, Tapes rhomboides, Glycymeris glycymeris and Venus verrucosa. For each species, individual age and weight were noticed. The spreading gastropod Crepidula fornicata was also sampled. The resultant biomass and distribution are proposed. These results will contribute to the evaluation of trophic exchanges in boundary layer and to the proposed modeling, in the program PNOC (National Program for Coastal Oceanography).
