Genetic Structure of Anchovy Engraulis encrasicolus in the Adriatic Sea using Microsatellite DNA Analysis

Stock structure analysis of anchovy from the Rovinj, Maslenica and Island of Korčulain in theAdriatic Sea was carried out by using 13 microsatellite loci. Overall, 259 alleles were detected in13 loci, the number of alleles per locus and population ranged from 4 to 28. The allelic richness ofoverall loci was found to be highest in the Rovinj population and lowest in the Island of Korčulapopulation. The highest and lowest value of population specific alleles was found in the Rovinjpopulation and Island of Korčula population, respectively. Observed heterozygosity per populationwas ranged from 0.714 (Rovinj) to 0.678 (Maslenica). Pairwise FST values revealed that there is nosignificant genetic differences between populations (P>0.05). However, the highest and lowestgenetic distance were found between the Rovinj and Maslenica populations (FST=0.00626) andbetween the Island of Korčula and Maslenica populations, respectively. The UPGMA dendrogramclustered the Maslenica and Island of Korčula populations together, and the Rovinj population wasa distinct cluster from these two.
