The complete mitogenome of the bighead pennah croaker was first determined in this study. It is 16,508 bp in length with the typical gene order and transcriptional direction in vertebrates containing 37 genes. The overall nucleotide composition is 27.5% A; 31.2% C; 16.0% G, and 25.3% T. The sizes of the 22 tRNA genes range from 68 to 75 bp. Two start (ATC and ATG) and three stop (AGA, TAG, and TAA/TA/T) codons were found in the protein-coding genes. In the Bayesian tree, all nodes were strongly supported based on the complete mitogenomes of 16 species from the family Sciaenidae. The phylogenetic results suggested has the closest relationship to the silver croaker , a species from the same genus.
本研究首次测定了大头彭纳石首鱼的完整线粒体基因组。其长度为16,508 bp，具有脊椎动物典型的基因排列顺序和转录方向，包含37个基因。总体核苷酸组成为：A占27.5%；C占31.2%；G占16.0%，T占25.3%。22个tRNA基因的大小范围为68至75 bp。在蛋白质编码基因中发现了两个起始密码子（ATC和ATG）和三个终止密码子（AGA、TAG和TAA/TA/T）。在贝叶斯树中，基于石首鱼科16个物种的完整线粒体基因组，所有节点都得到了有力支持。系统发育结果表明，它与同属的银身石首鱼关系最为密切。
