SUMMARY. In this study we evaluated the genetic diversity of silver (Hypophthalmichthys molitrix Val.) and bighead (Hypophthalmichthys nobilis Rich.) carps grown in aqua-culture in the territory of the Republic of Belarus. Genotyping was obtained for 11 STR-loci – Hmo11, Hmo13, Hmo15, Hmo25, Hmo26, Hmo31, Hmo33, Hmo 34, Hmo36, Hmo37, Hmo40. The following parameters were calculated: the average number of alleles per locus, the effective number of alleles, the levels of expected and observed heterozygosity, the value of the Shannon information index and the fixation indexes FIS. The obtained results indicate moderate (for silver carp) and sufficiently high (for bighead carp) genetic diversity of the studied samples of carps, up to the possibility to allocate several groups for subsequent work on obtaining linear material and further reproduction, including commercial fish. However, to achieve these goals, it is necessary to pay special attention to the selection of pairs of producers, taking into account the results of molecular genetic analysis. Evaluation of the genetic diversity of these species of herbivorous fish, bred in the Republic of Belarus, in comparison with the results of other researchers indicate a significant genetic resource of domestic producers.
