Thirty-four microsatellite DNA loci were developed for grass carp (Ctenopharyngodon idella) and used to determine the diversity of 42 individuals of grass carp and 16 individuals of black carp collected from Jingzhou fragment (the middle reach) of Yangtze River. All the 34 loci were polymorphic in grass carp. The number of alleles found in grass carp at these loci ranged from 2 to 24. The observed and expected heterozygosities varied from 0.238 to 1.000 and from 0.162 to 0.945, respectively. Thirty of the 34 loci cross-amplified the DNA of black carp (Mylopharyngodon piceus), and 21 of them revealed polymorphism (more than one allele each locus).
