Abstract：Abstract: Use microsatellite technology to study Genetic diversity of wild populations (HYE,
XYE,ZYE) and cultured Populations(XYA,XYA,ZYA) of Lutjanus erythopterus and Lutjanus stellatus and Lutjanus argentimaculatus from South China sea. The number of total alleles of the ten microsatellite loci is 78, the average number allele of every locus is 1~8. Mean observed heterozygosity (Ho) of six populations is:ZYE(0.9550)>ZYA(0.8900),HYE(0.8950)>HYA (0.8400)，XYE(0.8450)>XYA(0.8100); mean polymorphism information content (PIC) range form 0.3648 to 0.7964, the number of PIC of wild populations is greater than cultured populations. Genetic distances between wild populations and cultured populations of three species in respective snapper is 0.1029，0.0371，0.0135 and coefficients of gene differentiation is 0.0371，0.0211，0.0352. Study of population genetic structure shows that genetic diversity of three species of snappers is abundant, genetic diversity declines in cultured populations. faint genetic Differentiati-
on exists between wild populations and cultured populations.
