AbstractThe Hong Kong oyster, Crassostrea hongkongensis, is an important fisheries resource that is cultivated in the coastal waters of the South China Sea. Despite significant advances in understanding biological and taxonomic aspects of this species, no detailed study of its population genetic diversity in regions of extensive cultivation are available. Direct sequencing of the mtDNA cox1 gene region was used to investigate genetic variation within and between eleven C hongkongensis populations collected from typical habitats. Sixty-two haplotypes were identified; only haplotype 2 (21.74% of total haplotypes) was shared among all the eleven populations, and most of the observed haplotypes were restricted to individual populations. Both AMOVA and F-ST analyses revealed significant population structure, and the isolation by distance (IBD) was confirmed. The highest local differentiation was observed between the sample pools from Guangxi versus Guangdong and Fujian, which are separated by a geographic barrier, the Leizhou Peninsula. Current knowledge from seed management suggests that seed transfer from Guangxi province has likely reduced the divergence that somewhat naturally exists between these pools. The findings from the present study could be useful for genetic management and may serve as a baseline by which to monitor future changes in genetic diversity, either due to natural or anthropogenic impacts.
