RESUMO
The spotted babylon, Babylonia areolata, is one of the most extensively cultured marine mollusks in southeast Asia. Eight polymorphic microsatellite markers were developed for this species, from a microsatellite-enriched library. These markers, characterized in 32 individuals from a hatchery population, were polymorphic, with allele numbers ranging from 6 to 18 per locus, expected and observed heterozygosities ranging from 0.68 to 0.94 and 0.56 to 0.81, respectively. One locus (HUBA09) showed significant deviation from Hardy-Weinberg equilibrium, probably due to the presence of null alleles. These microsatellite loci should be useful for future population genetic studies and marker-assisted breeding in this species.

The abalone, Haliotis diversicolor, is one of the most important mariculture species in southern China. We developed 60 new polymorphic microsatellite markers for H. diversicolor and characterized them in 30 individuals from a cultured population in Sanya, China. All 60 markers were found to be polymorphic. The number of alleles ranged from two to nine per locus, with an average of 4.12/locus. The expected and observed heterozygosities ranged from 0.10 to 0.88 and from 0.07 to 0.87, respectively. Forty-four loci were in Hardy-Weinberg equilibrium. These 44 microsatellite markers should be useful for genome mapping and population genetic studies.
