Resumo: | The two common oyster species cultivated in Europe are the flat oyster Ostrea edulis and the cupped oyster Crassostrea gigas. These species have two really different reproduction strategies (oviparity versus larviparity) and histories (natural distribution versus introductions linked to oyster culture). We used microsatellite markers to compare the observed variabilities Europe wide. O. edulis presents a lower rate of alleles per locus than C. gigas. The observed structuration levels (global Fst and by pairs values) are similar for both species, but the spatial organisation of the diversity is different. In O. edulis, appears a differentiation based on the distance (concordance of the results with those obtained with the allozymes) whereas in C. gigas, genetic differentiation is the reflection of the successive importations (the said "Portuguese" and "Japanese" oysters).
