| Within the framework of the mission of creation of a “Parc Naturel Marin" in the Bay of Arcachon, estimations of the oysters stocks in the Bay were realized in 2011 by the engineering consulting firm Océanide, in association with the “Agence des Aires Marines Protégées”, the French Research Institute for the Exploitation of the Sea ( IFREMER) - Station of Arcachon and the Departmental Direction of Territories and the Sea of Gironde – “Délégation à la Mer et au Littoral (DLM)”. The evaluation of the stock of cultivated oysters was made from production statements of the shellfish farmers, collected in 2010 by the DML. The estimation of the stocks of wild oysters was made using a stratified two degrees field sampling. Finally, 82 500 t of oysters are present... |

| Each summer, the IFREMER laboratory of Arcachon monitors, in the scope of an agreement with the Regional Conchological Comity of Arcachon, the reproduction of Pacific oysters in the Arcachon Bay. This monitoring aims to provide oyster farmers with information necessary to the spat collecting: - dates and amount of spawn, - larval development speed, - presence of the most evolved stages in the habitat (close to fixation). Reproduction is monitored from June to September, with plankton being sampled four times a week on different representative sites. Oyster larvae at different stages are counted. At the end of the reproduction period (September-October), larval recruitment on collectors is estimated via the counting of the spats collected, at various... |
