Title: Microsatellite analysis on genetic diversity of wild and cultured populations of Scylla paramamosain
Abstract: To study the genetic diversity and population structure of the wild Scylla paramamosain population in the Sanmen Bay and the cultured population from Sanmen County,six microsatellite markers were used.A total of 66 alleles were obtained and the polymorphic information content(PIC) value per loci was greater than 0.5,indicating that the six loci were highly polymorphic and can be effectively used to analysis of genetic structure of the crab populations.The numbers of alleles of the wild and cultured populations in six loci ranged from 4 to 18,6 to 14 respectively.The mean heterozygosity of the two populations were 0.577,0.561,while the mean PIC value were 0.779,0.828.The coefficient of genetic differentiation(FST) was 0.0317.The genetic similarity index and genetic distance were 0.7930,0.2319,respectively.All of these showed that the genetic diversity of the two populations was relatively abundance,and faint genetic differentiation existed between the wild population and cultured population.
