Mystus gulio
Hamilton, also called long whiskers catfish, is an endemic fish and a common food in some Asian countries. In this study, the complete mitochondrial genome of
M. gulio
was sequenced using the MinION system (Oxford Nanopore Technologies). The mitochondrial genome is 16,518 bp in length (41.1% [G + C] content) and consists of 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The results of phylogenetic analysis inferred from whole mitochondrial genomes of
Mystus
and related species in the family Bagridae revealed that
M. gulio
is closely related to
Mystus cavasius
.
