Abstract

Stock structure analysis of anchovy from the Rovinj, Maslenica and Island of Korčulain in the Adriatic Sea was carried out by using 13 microsatellite loci. Overall, 259 alleles were detected in 13 loci, the number of alleles per locus and population ranged from 4 to 28. The allelic richness of overall loci was found to be highest in the Rovinj population and lowest in the Island of Korčula population. The highest and lowest value of population specific alleles was found in the Rovinj population and Island of Korčula population, respectively. Observed heterozygosity per population was ranged from 0.714 (Rovinj) to 0.678 (Maslenica). Pairwise FST values revealed that there is no significant genetic differences between populations (P>0.05). However, the highest and lowest genetic distance were found between the Rovinj and Maslenica populations (FST=0.00626) and between the Island of Korčula and Maslenica populations, respectively. The UPGMA dendrogram clustered the Maslenica and Island of Korčula populations together, and the Rovinj population was a distinct cluster from these two.
