is an economically important fish that is often erroneously identified as . No population genetic analyses have been performed on the true species. Here, the mitochondrial control region (CR) was used to evaluate the population genetics and elaborate the historical demography of the Silver pomfret collected from six geographical locations in China, Pakistan, and Kuwait. A high level of genetic diversity was demonstrated in this species. Analysis of molecular variance (AMOVA) revealed that the genetic divergence was mainly derived from within the populations ( < 0.05). A historical demographic analysis indicated that the Silver pomfret experienced a recent population expansion during the late Pleistocene. The phylogeographical structure revealed two obvious lineages that diverged in the late Pleistocene, during which the Silver pomfret populations historically experienced exotic divergence and mixed again with differentiated populations. Currently, Silver pomfret populations have insufficient time to attain migration-drift equilibrium. Population genetic data of the Silver pomfret can provide preliminary genetic knowledge for its fishery management.
是一种具有重要经济意义的鱼类，常被错误地认定为 。尚未对真正的 物种进行群体遗传学分析。在此，利用线粒体控制区（CR）来评估群体遗传学，并阐述从中国、巴基斯坦和科威特六个地理位置采集的银鲳的历史种群动态。该物种表现出高水平的遗传多样性。分子方差分析（AMOVA）表明，遗传分化主要源自种群内部（ < 0.05）。历史种群动态分析表明，银鲳在晚更新世经历了近期的种群扩张。系统地理学结构揭示了两个明显的谱系，它们在晚更新世分化，在此期间，银鲳种群历史上经历了异域分化，并再次与分化的种群混合。目前，银鲳种群没有足够的时间达到迁移 - 漂变平衡。银鲳的群体遗传数据可为其渔业管理提供初步的遗传知识。
