为了研究种群间遗传分化的程度，利用线粒体DNA(MtDNA)控制区对采自韩国8个地点和日本4个地点的野生种群斑点石斑鱼的遗传多样性进行了研究。发现了两种不同的线粒体谱系：A谱系仅分布在韩国沿海水域，并主导着韩国西部和西南海岸群。而日本团体OFK。两个谱系在韩国沿海东南部和东部海岸的共存表明，目前的沙鱼种群分布格局是由二次接触构成的。
To investigate the extent of genetic differentiation among populations, genetic polymorphism in gizzard shadKonosirus punctatus, collected from wild populations of eight locations in Korea and four locations in Japan, was examined using mitochondrial DNA (mtDNA) control region. Two distinct mitochondrial lineages were detected: Lineage A was only distributed around Korean coastal waters and dominates the western and southwestern coast group of Korea. While Japanese groups ofK. punctatuswere exclusively assigned to lineage B. The co-occurrence of both lineages in southeast and east coasts of Korean coastal waters indicated that the current distribution pattern of gizzard shad populations was constructed by secondary contact.
