Barfin flounder (Verasper moseri) and spotted halibut (Verasper variegatus) are two commercially important flatfish species in the Northeast Asia. In the present study, we reported polymorphic microsatellite markers in V. moseri and V. variegatus by the cross-species amplification of microsatellite primers developed previously in two other related marine fish species. A total of 244 polymorphic microsatellite markers were selected for cross-species amplification in V. moseri and V. variegatus, of which 182 markers deriving from Atlantic halibut (Hippoglossus hippoglossus) and 62 markers deriving from Japanese flounder (Paralichthys olivaceus). A sample of 10 individuals were detected. As a result, a total of 67 loci showed polymorphisms in V. moseri, and 62 loci showed polymorphisms in V. variegatus, with the observed number of alleles per locus ranging from two to five in V. moseri, and from two to seven in V. variegatus, respectively. This paper provided more candidate microsatellite markers which could be useful for construction of genetic linkage maps, evaluation of population genetic structure and stock management of V. moseri and V. variegatus.
