The complete mitochondrial genome of the blackskin catfish (Clarias meladerma: Clariidae) from Rokan River, Riau, Indonesia

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.

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.
