摘要

The complete mitochondrial genome of Trichogaster trichopterus was determined in this study. It is 16,452 bp in size and consists of 2 rRNA genes, 13 protein-coding genes, 22 tRNA genes and 1 non-coding control regions (D-loop). The overall base composition of the heavy strand of the T. trichopterus mitochondrial genome is A: 29.50%, T: 28.36%, C: 26.62% and G: 15.49%. The total length of the 13 protein-coding genes was 11,427 bp. Analysis of the genes indicated the high genetic variability among Osphronemidae species.
