| Shellfish areas usually receive a large number of introduced species. During the present project, we specially focused on 4 marine benthic molluscs introduced in shellfish areas along the Channel and Atlantic coasts of France: the gastropods Crepidula fornicata, Ocinebrellus inornatus and Cyclope neritea, and the bivalve Ruditapes philippinarum. Our study was conducted according to three main axes: (i) the characterization of introduction and expansion patterns of species within their newly colonized area. In the three invasive gastropods C. fornnicata, C. neritea and 0. inornatus, a high level of genetic diversity was detected in the French populations which indicated a complex process of introduction (with multiple population sources or secondary... |

| The direct amplification of length polymorphism technique (DALP) has been used to distinguish species-specific banding patterns in two marine gastropod oyster drills Ocenebra erinacea (Linnaeus, 1758) and Ocinebrellus inornatus (Recluz, 1851). Ocenebra erinacea is the European oyster drill, common along all European coasts. Ocinebrellus inornatus, the Japanese oyster drill, was recorded in oyster growing areas of the Marennes-Oleron Bay (SW France) for the first time in 1995. This new biological invasion could lead to an increase, which must be evaluated, in the predation risk for cultivated species i.e. oysters and blue mussels, and for littoral fishing resources along the French Atlantic coasts. As a result, since specific identification of early life... |
