Abstract

The Chilean jack mackerel (Trachurus murphyi, Nichols, 1920) is a pelagic fish of high fishery interest, with a global capture of 828,358 mt in 2021. We report the complete mitochondrial genome of T. murphyi (Teleostei, Carangidae), collected in Bahia de Zapallar, Chile (32°33'02.59'' S, 71°27'55.38'' W). The size of the mitogenome is 16,561 bp (H-strand composition: 25.9% A, 16.7% C, 29.8% G, and 27.5% T). The mitogenome has the classic vertebrate gene content of 13 protein-coding, two rRNA, and 22 tRNA genes, as found in Carangidae and other Teleostei families. Phylogenetic analysis using mitochondrial genomes of 22 related species revealed that T. murphyi formed a well-supported monophyletic group with the other Trachurus species, being T. simmetricus its closest relative. Sequencing the mitochondrial genome from T. murphyi is the first step in developing traceability tools based on DNA analysis to enforce fishing quotas and trace the processed food and foodstuff containing Chilean jack mackerel following the objective of the South Pacific Regional Fisheries Management Organization (SPRFMO).

智利鲐鱼（Trachurus murphyi Nichols，1920 年）（远洋鱼类，鲤科）的完整线粒体基因组。

智利竹筴鱼（Trachurus murphyi, Nichols, 1920）是一种中上层鱼类，具有很高的渔业价值，2021年全球捕获量为828,358公吨。我们报告了在智利Bahia de Zapallar（南纬32°33'02.59''，西经71°27'55.38''）采集的T. murphyi（远洋鱼类，鲤科）的完整线粒体基因组。有丝分裂基因组大小为 16,561 bp（H 链组成：25.9% A、16.7% C、29.8% G 和 27.5% T）。有丝分裂基因组具有典型的脊椎动物基因含量，包括 13 个编码蛋白质的基因、2 个 rRNA 基因和 22 个 tRNA 基因，这在鲤科和其他长尾目鱼类中也有发现。利用 22 个相关物种的线粒体基因组进行的系统发育分析表明，T. murphyi 与其他鳟鱼物种形成了一个支持良好的单系群，T. simmetricus 是它的近亲。根据南太平洋区域渔业管理组织（SPRFMO）的目标，对T. murphyi的线粒体基因组进行测序是开发基于DNA分析的可追溯工具的第一步，以执行捕捞配额并追踪含有智利鲭鱼的加工食品和副食品。
