Genetic structure of gilthead sea bream (Sparus aurata) in the Adriatic Sea inferred with microsatellite markers

The two new standardised panel of microsatellite multiplex (SMsa1 and SMsa2, Lee- Montero et al. 2013) have been applied to detect genetic structure of the gilthead sea bream in the Adriatic Sea. Together with the European sea bass, gilthead sea bream is the leading mariculture species in the Mediterranean as well as in Adriatic, with important economic value. The aim of the study was to assess genetic differentiation among wild and farmed, sea bream assemblages in the eastern Adriatic Sea as well as to detect potential impact of aquaculture on the wild sea bream populations. Within wild fish populations, special attention was devoted to the aggregated seabream populations around tuna fish farms and juveniles of F0 wild generation, aiming to identify potential introgressive hybridization.
