本文从年幼（YOY）个体线粒体DNA （mtDNA）控制区研究了东海大黄颡鱼（greater amberjackSeriola dumeriliin East China Sea， ECS）的分布和遗传变异，这可能反映了产卵群体的遗传特征。在2016年和2017年，共有165个年度。从欧洲经济区的两个不同地点收集了小百合：欧洲经济区的南部和日本西海岸。利用在ECS中收集的67只幼虫和幼鱼的耳石每日增量来估计产卵期。大小和年龄分布的结果表明。1 - 4月，东中国海南部陆架断裂区附近出现了小海茅。基于mtDNA序列数据的系统发育分析显示，不同地点采集的样品之间没有显著的遗传分化。小檗属植物主要由一个种群组成。日本海岸附近的浮冰可能起源于欧洲南部。
We examined the distribution and genetic variability of the greater amberjackSeriola dumeriliin the East China Sea (ECS) from the mitochondrial DNA (mtDNA) control region of young-of-the-year (YOY) individuals, which may reflect the genetic characteristics of the spawning population. In the years 2016 and 2017, a total of 165 YOYS. dumeriliwere collected from two different locations in the ECS: the southern part of the ECS, and western Japanese coast. The spawning period was estimated using otolith daily increments from a total of 67 larvae and juveniles collected in the ECS. Results from size and age distribution indicated thatS. dumerilispawned near the shelf break region in the southern ECS from January to April. Phylogenetic analysis based on mtDNA sequence data showed no significant genetic differentiation among samples collected from different locations, implyingS. dumeriliin the ECS is mainly composed of one population.S. dumeriliaround the Japanese coast may be originated from the southern ECS.
