我国中国鲳的种群遗传结构和系统地理格局研究

中国鲳是我国鲳属鱼类的重要成员，具有较高的营养价值和经济价值。近年来，由于过度捕捞和环境污染等原因，我国海区的鲳属鱼类资源呈现衰减趋势。本研究采用线粒体DNA控制区和细胞色素b基因、微卫星DNA等分子标记，结合分节特征、量度特征等多变量分析，系统地研究我国海区中国鲳的遗传多样性、种群遗传结构及其地理分布格局，探讨海洋水文分布和地质构造特征等环境因素对该物种的形成、分布扩散途径以及基因交流和系统进化的影响。研究成果不仅可为我国中国鲳资源现状的评价、管理和合理开发利用提供科学依据，同时也将促进海洋生物分子系统地理学研究的发展，对于有类似分布和生物学特性的其它海洋生物类群也有重要的借鉴和参考价值。

Pampus chinensis, an important member of Pampus species in China, has high nutritional and economic values. In recent years, due to overfishing and environmental pollution, decline in resource of Pampus species was found in China water. In the present study, morphological (multivariate analysis of meristic and morphometric characters), mitochondrial DNA control region, cytochrome b sequences and microsatellite markers will be used to estimate the genetic diversity, population structure and phylogeographic pattern of Pampus chinensis in China water systematically. Also, the influence of environmental factor (such as ocean current pattern and geographical characters) on the formation, diffusion path, gene flow and phylogeny evolution will be discussed. The results would not only provide scientific information for the evaluation, management, and rational exploitation and application of this species in China, but also promote the development of molecular phylogenography study in marine organism, and provide reference for marine species that have similar distribution and biological characteristics.
