The Chorus- Parc des Expositions de Vannes is organising the leading national professional meeting just prior to the shellfish growing season, in close collaboration with numerous partners: the South Brittany Regional Shellfish Growers" Committee, the Regional Council of Brittany, the Departmental Council of the Morbihan, France Agrimer, the Coopérative Maritime and the regional branch of the Crédit Maritime Atlantique.

Every year, this show hosts nearly 90 exhibitors presenting their materials, equipment and services. The last edition of the National Shellfish and Marine Culture Show in Vannes was widely acclaimed: by visitors, exhibitors and partners.
