Microsatellite markers for population genetic studies of the giant red shrimp Aristaeomorpha foliacea (Crustacea Decapoda)

Microsatellite markers have been isolated and characterized from the giant red shrimp Aristaeomorpha foliacea in order to investigate on the presence of distinct stocks in the Western Mediterranean Sea. Polymorphism of the newly obtained loci was assessed in a restricted sample of 30 specimens, nine loci provided markers with polymorphism (range 2–19 alleles per locus). Six loci, the most polymorphic and easiest to amplify and to score, were tested in a larger sample of 6 populations from the Western Mediterranean Sea. Microsatellite data revealed a substantial genetic homogeneity and no signs of recent bottlenecks, suggesting the existence of a high gene flow that connects all population
