Abstract
Pleuronectidae is a well-studied familyin the order Pleuronectiformes. In contrast, genetic research on the flatfish Acanthopsetta nadeshnyi of the Pleuronectidae family is limited. This study reports the complete mitogenome of A. nadeshnyi. The mitogenome was 17,206 bases long and included 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a putative control region. Phylogenetic analysis based on the nucleotide sequences of the 13 PCGs confirmed that A. nadeshnyi belongs to the Pleuronectidae family.
