摘要：

The complete mitochondrial genome of Symphysodon discus Heckel 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).
