Characterization of ten polymorphic microsatellite markers in an invasive Ponto-Caspian mysid crustacean Paramysis lacustris

Paramysis lacustris is a Ponto-Caspian mysid crustacean species. It inhabits coasts, estuaries and lower parts of rivers in the Black, Azov and Caspian seas and shows high levels of genetic structuring and cryptic diversity. The species has been introduced into the Baltic Sea basin and is considered to be a high risk invader. We developed ten microsatellite loci and tested their polymorphism in 70 individuals from four wild populations. The number of alleles per locus ranged from 4 to 23; none of the loci showed consistent deviations from Hardy–Weinberg equilibrium. These microsatellite markers will be useful to trace potential invasions and understand dynamics of native P. lacustris populations.
