Description
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 Pointe-de-Grouin to Pointe-de-Champeaux line.
