摘要
赤点石斑鱼Epinephelus akaara作为我国南方海域的经济水产鱼类,已面临着种质资源匮乏,过度开发的局面。为了开展其保护生物学研究和促进养殖业的健康发展,开展了赤点石斑鱼群体的微卫星分析,对中国东南沿海7个赤点石斑鱼群体的遗传变异进行了研究,发现在不同渔场之间的种群存在着丰富的遗传多样性,并且具有明显的地理区域分布特征,这为赤点石斑鱼的种质资源研究和遗传育种提供了遗传学基础。
The red spotted grouper has been considered to be at risk of being overexploited in China and its artificial seeds had the low larval survival rates and low stability. Efficient measures therefore must be taken for surveillance, conservation and utilization of this species with its available genetic resources. In this study, a total of 7 simple sequence repeat （SSR） markers were used to assess genetic diversity for the red spotted groupers from 7 different typical fishing grounds across Southern China Sea and East China Sea. The high polymorphism information contents at the 7 markers implied that the red spotted groupers keep natural variation from different offshore fishing grounds in China. Analysis of genetic differentiation indicated substantial divergence among the red spotted groupers. Phylogenetic analyses displayed a remarkable degree of consistency between geographic locations and the pattern of genetic differentiation.
