- We isolated six polymorphic microsatellite loci in the migratory freshwater fish Prochilodus costatus, which is an endemic species and important fisheries resource from São Francisco river basin, Brazil. We have evaluated the applicability of these loci to study genetic variation in wild population of this fish. Thus, based on the genotypes of 32-48 individuals, we detected two to 21 alleles per locus, observed and expected heterozygosities ranging from 0.19 to 0.89 and from 0.17 to 0.92, respectively. These polymorphic markers should provide efficient tools to study population genetic structure of this fish.
