A set of primers to amplify 10 microsatellite DNA loci was developed for the Neotropical fish Cichla piquiti, one of the largest sized cichlids in the Amazon Basin. These loci were used to genotype individuals from two populations, one native population from the Tocantins River, the other an introduced population in southeast Brazil, Upper Paraná River. Cross-amplification was also successful for another species of peacock bass, C. kelberi. An average of 4.4 alleles per locus (2-9 alleles) was detected. These markers will be useful for the characterization of genetic structure of native populations, and also for invasive biology studies since Cichla species have been introduced in many river basins outside their native ranges.
