The complete mitochondrial genome was sequenced from the freshwater fish, Pseudobagrus medianalis (Siluriformes: Bagridae) in this study. The genome sequence was 16,647 bp in length, and the gene order and contents were identical with the bagridae fishes. The mitochondrial genome contains 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and 2 non-coding regions (control region and origin of light-strand replication). All genes were encoded on the heavy strain except for ND6 and eight tRNA genes. The overall base composition is 25.7% A, 30.9% T, 28.0% G, 15.4% C, with an A+T bias of 56.6%. The complete mitogenome data provides useful genetic markers for the studies on the molecular identification, population genetics, phylogenetic analysis and conservation genetics.
本研究对淡水鱼中间黄颡鱼（鲇形目：鲿科）的完整线粒体基因组进行了测序。基因组序列长度为16647 bp，基因顺序和内容与鲿科鱼类相同。线粒体基因组包含13个蛋白质编码基因、2个核糖体RNA、22个转运RNA和2个非编码区（控制区和轻链复制起点）。除ND6和8个tRNA基因外，所有基因均由重链编码。总体碱基组成为25.7%A、30.9%T、28.0%G、15.4%C，A+T偏倚为56.6%。完整的线粒体基因组数据为分子鉴定、群体遗传学、系统发育分析和保护遗传学研究提供了有用的遗传标记。
