Popis: Labeo fimbriatus, the fringe-lipped peninsula carp, is a commercially important fish species next to Indian major carps. We isolated and characterized polymorphic microsatellite markers to be used as a tool for delineation of genetic stock of this species. Partial genomic libraries enriched for CT and GT repeat motifs generated 103 positive clones out of which 16 loci were found with flanking regions enough for designing primers. Thirty-two individuals of L. fimbriatus collected from wild were used to characterize the polymorphism. All the 16 loci were polymorphic with allele numbers ranging from 3 to 9. The observed and expected heterozygosity ranged from 0.093 to 0.833 and from 0.146 to 0.843, respectively. Nine loci were in agreement with Hardy–Weinberg equilibrium. No significant pair wise linkage disequilibrium was found among the loci. These markers would be very useful for characterization of natural populations of this species.
