Tissue samples from 84 Pampus chinensis individuals were collected from four geographic regions within the Indo–Pacific Ocean and analyzed using mitochondrial and nuclear DNA markers. Distinct genetic heterogeneity was found for both types of markers between Chinese and Pakistani populations, while the diversity of this species was high in all populations. In combination with published information on marine species with similar distributions, these results suggested that the Malay Peninsula, or a less effective supplement, played a role in shaping the contemporary genetic structure. This population structure was presumably reflected in P. chinensis, whose populations were genetically isolated during Pleistocene glaciations and then did not experience secondary contact between previous refuge populations. However, P. chinensis showed genetic continuity in China or Pakistan, which indicated that the populations in different geographical regions constituted a single panmictic stock with high gene flow, respectively. The spatial genetic subdivision evident among populations indicates that P. chinensis in this Indo–Pacific region should be managed as different independent stocks to guide the sustainability of this fisheries resource. |
