Introduction: During each summer season, the IFREMER laboratory of Arcachon monitors, within the framework of the agreement with the Arcachon- Aquitaine Shellfish Farming Regional Section (SRC), the reproduction of cup oysters in the Arcachon basin. This monitoring has as its goal to furnish oyster farmers with the information needed to implement spat catches: - dates and size of egg clutches, - larvae development rate, - presence in the environment of more evolved stages (close to fixation). Reproduction was monitored between mid-June and mid-September, plankton was fished four times per week at the various sites representative of the basin. Oyster larvae at various stages are enumerated there. At the end of the reproductive season (September to... |

Introduction: Marine farming in France is currently very widely dominated by oyster farming. French oyster production totals 148,467 tons, for a turnover of close to 280 million euros, making France the leading European producer. The two main species concerned are the cup oyster, Crassostrea gigas (140,000 tons) and the flat oyster, Ostrea edulis (2,000 tons), the production of which has collapsed since 1970 following successive epizootics of Marteilia refringens and Bonamia ostreae. French oyster farming is thus in a situation of quasi single-crop farming, with more than 90% of tonnage pertaining to the cup oyster (FAO data from 1993). This situation of quasi single-crop farming leads to the pessimistic observation that one hypothetical crisis in the... |

Depuis 2010, le programme HLiN s’attache à suivre la colonisation et le recrutement des huîtres naturelles sur les côtes du département de la Manche. Après une période d’adaptation des protocoles à la réalité normande, il s’est posé la question de l’origine du recrutement des huîtres, notamment pour la côte ouest du Cotentin, entre les falaises de Champeaux et Saint Germain / Ay. Suite à ses travaux sur la dérive larvaire des moules de pêche en baie de Seine, le LERN de Port en Bessin avait mis au point un modèle de courantologie en 3 dimensions appelé NORM (issu du code MARS 3D). L’idée était d’appliquer la méthodologie de calage du modèle pour le golfe normand breton afin de simuler différents scénarios de ponte et de les corréler avec les observations... |
