## TL;DR

This study sequenced the complete mitochondrial genome of the blackskin catfish from Indonesia and analyzed its genetic relationships with other catfish species.

## Contribution

The study provides the first complete mitochondrial genome sequence of Clarias meladerma and its phylogenetic placement.

## Key findings

- The mitochondrial genome of C. meladerma is 16,808 bp long and contains 13 protein-coding genes, 22 tRNA genes, and two rRNA genes.
- Phylogenetic analysis shows C. meladerma clusters with C. macrocephalus, C. batrachus, and C. fucus.
- The base composition of the mitogenome is 32.49% adenine, 25.75% thymine, 14.51% guanine, and 27.25% cytosine.

## Abstract

Clarias meladerma Bleeker, 1846, a native catfish species in Indonesia belonging to the family Clariidae. The present study the complete mitochondrial genome sequence of C. meladerma from the Rokan River was sequenced by using next-generation sequencing, and its phylogenetic relationship was analyzed. The mitochondrial genome comprises 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes, with a total length of 16,808 bp. The mitogenome of C. meladerma exhibits a base composition of 32.49% adenine, 25.75% thymine, 14.51% guanine, and 27.25% cytosine. Phylogenetic analysis indicated that C. meladerma has the same clade with C. macrocephalus, C. batrachus, and C. fucus. In essence, the findings of this study lay down a genetic foundation for future investigations into C. meladerma.
