The complete mitochondrial genome of water flea Ceriodaphnia dubia (Crustacea: Cladocera) NIES strain.

Water flea Ceriodaphnia dubia has been widely used for risk assessments of chemicals and environmental contamination. In this study, the complete mitochondrial genome (mitogenome) of this species NIES strain was determined using short-read high throughput and long-read sequencing technologies. The mitogenome of C. dubia was 15,170 bp in length and consisted of 13 protein-coding genes (PCGs), 2 ribosomal RNAs (rRNAs), and 22 transfer RNAs (tRNAs). The gene order was identical to the pattern conserved across crustaceans. The complete mitogenome of the NIES strain will serve as genetical reference in ecological risk assessments in Japan, as well as resources for future phylogenetical studies using cladocerans.
