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

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.
