The complete mitochondrial genome of Silurus lithophilus, a catfish endemic to Lake Biwa, Japan

Abstract

We determined the complete mitochondrial DNA sequence of Silurus lithophilus, a catfish endemic to Lake Biwa, Japan. The mitogenome was 16,524 bp in length and the gene contents and order agreed with those of typical vertebrates. A molecular phylogenetic analysis based on 12 published Silurus mitogenomes showed that the mitogenome of S. lithophilus (LC520058) was closest to that of Silurus asotus from Japan (AP012022). These two mitogenomes were identical in the short (ca. 170 bp) gene region widely used in metabarcoding for environmental DNA analysis of fishes.
