A phylogeographic analysis based on 6 polymorphic microsatellites was performed on 15 sea bass samples. five from Western Mediterranean, seven from Eastern Mediterranean and three coming from French aquaculture stocks. Among the eastern samples, three did not cluster according to their geographic origin but rather with the occidental group. Furthermore. a somewhat lower allelic diversity was observed within these particular samples, indicating that they originated from a limited number of progenitors of foreign origin. Among the aquaculture stocks, only one revealed a significant reduction of genetic variability, indicating that these stocks are largely outbred and open to wild fishes. The fact that the use of occidental fingerlings to seed broodstocks in...
