AbstractThe carpet-shell clam Ruditapes decussatus (familyVeneridae) is a bivalve mollusk of great interest in fisheries and aquaculture. It lives buried in sandy bottoms of the intertidal zone in the Mediterranean Sea and adjacent Atlantic regions. The life cycle is characterized by a planktonic larval phase of 2-3 weeks and a sessile adult stage that can last for several years. Some of the carpet-shell clam stocks are experiencing over fishing. The introduction of exotic species such as the manila clam R. philippinarum is also a pressure on R. decussatus populations since they compete for space and resources. Due to aquaculture, an extensive mixing of stocks at some localities could be taking place, with unpredictable consequences to the integrity of the species’ genetic diversity. For all these reasons the study of the genetic structure of carpet-shell clamis of great interest.
