The is an important freshwater fish in the Amazon basin of South America, more expensive than . Here, we describe the complete 17,100 base pair (bp) mitochondrial genome of mohavensis. The mitogenome has a nucleotide base composition of A (29.62%), T (29.41%), G (15.39%), and C (25.62%), and encodes 13 protein subunits, 22 tRNAs, a 12S rRNA of 952 bp and 16S rRNA of 1665 bp, and a 1433 bp D-loop control region, each located in the conserved mtDNA structure typical for Characidae fishes. All protein-coding genes have initiation codons of ATG, ND1, ND2, CO2, ND3, ND4L, ND5, ND6 and Cytb ended by TAA as a stop codon, ND4 ended by AGA as a stop codon, CO1 ended by AGG as a stop codon, ATP8 and CO3 ended by TAG as a stop codon, ATP6 ended by ATT as a stop codon. This characterised mitogenome may help inform management practices for mohavensis by facilitating future studies on how allopatric populations of this imperilled species are evolving across refuge habitats.
[鱼名]是南美洲亚马逊河流域一种重要的淡水鱼，比[另一种鱼名]更昂贵。在此，我们描述了莫哈韦[鱼名]完整的17100个碱基对（bp）的线粒体基因组。该线粒体基因组的核苷酸碱基组成为：A（29.62%）、T（29.41%）、G（15.39%）和C（25.62%），编码13个蛋白质亚基、22个tRNA、一个952bp的12S rRNA和一个1665bp的16S rRNA，以及一个1433bp的D环控制区，它们各自位于脂鲤科鱼类典型的保守线粒体DNA结构中。所有蛋白质编码基因的起始密码子均为ATG，ND1、ND2、CO2、ND3、ND4L、ND5、ND6和Cytb以TAA作为终止密码子结束，ND4以AGA作为终止密码子结束，CO1以AGG作为终止密码子结束，ATP8和CO3以TAG作为终止密码子结束，ATP6以ATT作为终止密码子结束。这种具有特征性的线粒体基因组可能有助于为莫哈韦[鱼名]的管理实践提供信息，通过促进未来对这种濒危物种的异域种群如何在避难栖息地中进化的研究。
