In this study, the mitochondrial genome ofGlossolepis incisus(Weber 1907) (Atheriniformes: Melanotaeniidae) was sequenced for the first time. The assembled mitogenome consisting of 16 529 bp, includes 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes and 1 putative control region. The overall base composition ofG. incisusis 27.51% for A, 30.04% for C, 16.06% for G, 26.39% for T and showS 91% identities to Lake Kutubu Rainbowfish,Melanotaenia lacustris. These data will provide useful molecular information for phylogenetic relationships within the family Melanotaeniidae species. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genome ofSymphysodon discusHeckel was 16 544 bp in length, consisting of 22 tRNA genes, 13 protein-coding genes, 2 ribosomal rRNA genes, and a control region or displacement loop (D-loop). With the exception of 8 tRNAs and ND6 genes, the others were encoded on H-strand. The base composition on H-strand was 30.04% C, 28.39% A, 26.49% T and 15.07% G, exhibiting an A + T rich pattern. The codon usage was consistent with the other vertebrate mitochondrial pattern, i.e. start codon is ATG or GTG and stop codons are TAA, TAG or T– –. Stop codon TAG was only found in the ND6. There were 8 regions of gene overlapped with the length of 26 bp in total and 12 intergenic spacer regions (99 bp in total). [ABSTRACT FROM AUTHOR]

In this study, the complete mitogenome sequence of the Parkinson's Rainbowfish,Melanotaenia parkinsoni(Atheriniformes: Melanotaeniidae) has been sequenced by next-generation sequencing method. The assembled mitogenome is 16 529 bp in length including 13 protein-coding genes, 22 transfer RNAs and 2 ribosomal RNAs genes. The overall base composition of Parkinson's Rainbowfish is 28.1% A, 29.7% C, 15.7% G, 26.5% T and shows 93% identity with Lake Kutubu Rainbowfish,M. lacustris.The complete mitogenome of the Parkinson's Rainbowfish provides essential and important DNA molecular data for further phylogeography and evolutionary analysis for Rainbowfish phylogeny.
