Abstract Here, we report for the first time a comprehensive survey of the DNA barcoding of commercially important groupers in Aceh waters, Indonesia using the cytochrome oxidase subunit I (COI) gene. The fish samples were collected from major fish landing sites and fish markets in nine districts in Aceh, that covered the western and eastern coastal ecosystems of Aceh. In total, the 144 COI sequences revealed 26 grouper species with most represented by multiple specimens. As expected, genetic distances increased from lower to higher taxonomic levels: 0 %–1.27 % within species, 3.79 %–19.96 % within genus and 13.84 %–24.15 % within family. Out of the total species, 23 (88.5 %), were categorised as Least Concern (LC) and three species (11.5 %) were Data Deficient (DD) under the IUCN Red List. Furthermore, four species were categorized under ‘decreasing population trend’ (Epinephelus bleekeri, E. coioides, Plectropomus leopardus, and Variola albimarginata). This study is a significant contribution to the DNA barcode library of groupers in this region and expansion of the Indonesian and the global barcode entries in general.

印度尼西亚亚齐重要商业石斑鱼（石斑鱼科）的 DNA 条形码

摘要 在这里，我们首次报告了使用细胞色素氧化酶亚基 I (COI) 基因对印度尼西亚亚齐水域中具有重要商业价值的石斑鱼的 DNA 条形码进行全面调查。鱼类样本来自亚齐九个地区的主要鱼类登陆点和鱼类市场，涵盖亚齐西部和东部沿海生态系统。总共 144 个 COI 序列揭示了 26 个石斑鱼物种，其中大多数由多个标本代表。正如预期的那样，遗传距离从较低到较高的分类水平增加：物种内 0%–1.27%，属内 3.79%–19.96% 和科内 13.84%–24.15%。在 IUCN 红色名录中，23 个（88.5%）物种被归类为最不关心（LC），3 个物种（11.5%）被归类为数据缺乏（DD）。此外，四种物种被归类为“种群数量减少趋势”（Epinephelus bleekeri、E. coioides、Plectropomus leopardus 和 Variola albimarginata）。这项研究对该地区石斑鱼的 DNA 条形码库以及印度尼西亚和全球条形码条目的扩展做出了重大贡献。
