Exploited bivalves are economically important resources for coastal areas. Among these resources, Manila clams (Ruditapes philippinarum) and European clams (Ruditapes decussatus) are found in a variety of ecosystems (lagoons, bays, coasts, etc.) and support relatively substantial professional and recreational fishing activities.

This international conference aims to bring together scientists from several nations whose common point is to work on R. philippinarum and/or R. decussatus. It will be also a privileged place to gather scientists and stakeholders to strengthen links between them.

Five thematic sessions are planned (definitive sessions fixed later):

1. Life-history traits (reproduction, spawning, growth, mortality, health status, demography, etc.);
2. Evolutionary and functional processes (genetic diversity and structure, functional traits, selection, speciation, micro & macro evolution, etc.);
3. Biotic interactions (trophic and spatial competition, pathogenecity, predation, co-evolution etc.);
4. Habitat and environmental factors (spatial distribution, ecosystem ecology, global change, etc.);
5. Fisheries and management: from species to ecosystem (stock management, reseeding, restoration, aquaculture, governance, ecosystem service, sustainability, co & adaptative management, mitigation solution, etc.).

The presentations will be oral communications and posters. A special issue of Aquatic Living Resources ("Diamond" open access journal) is planned.

This conference will be held in Arcachon (SW France) from September 8 to 10, 2025. The event will take place at the Palais des Congrès in front of the Arcachon Bay (September 8-9) and will include a field trip (September 10).
