The Chagos archipelago in the British Indian Ocean Territory (BIOT) has been lacking in detailed genetic studies of its chondrichthyan populations. Chondrichthyes in Chagos continue to be endangered through illegal fishing operations, necessitating species distribution and abundance studies to facilitate urgent monitoring and conservation of the species. Here, we present a complete mitochondrial genome of the Silvertip Shark, sampled in the Chagos archipelago. The mitochondrial genome of was 16,706 bp in length and consisted of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, a replication origin and a D-loop region. GC content was at 38.7% and the control region was 1,065 bp in length. We expect that mitogenomes presented here will aid development of molecular assays for species distribution studies. Overall these studies will promote effective conservation of marine ecosystemes in the BIOT.
英属印度洋领地（BIOT）的查戈斯群岛一直缺乏对其软骨鱼类种群的详细基因研究。查戈斯群岛的软骨鱼类因非法捕鱼活动而持续濒危，因此需要进行物种分布和丰度研究，以便对这些物种进行紧急监测和保护。在此，我们展示了在查戈斯群岛采集的银鳍鲨的完整线粒体基因组。该线粒体基因组长度为16,706 bp，由13个蛋白质编码基因、22个tRNA基因、两个rRNA基因、一个复制起点和一个D-loop区域组成。GC含量为38.7%，控制区域长度为1,065 bp。我们期望这里展示的有丝分裂基因组将有助于开发用于物种分布研究的分子检测方法。总体而言，这些研究将促进对英属印度洋领地海洋生态系统的有效保护。
