Sinipercids are a group of freshwater perciform fish endemic in East Asia with the majority of species
recorded in China. In the present study, we analyzed the organizations of complete mitogenomes of the six
sinipercid fish populations from the Yangtze River and the Pearl River systems in China. The proportion of G was
relatively low just at 16.2%-16.5% among the fish populations analyzed. The similarity and divergence analysis
showed that the populations from different drainages have more sequence similarities than those from different
species in the same drainages. The rate of point mutation was 0.39% and a total of 422 variable sites were
identified in the 12 protein-coding genes (excluding the ND6) among the four S. scherzeri populations. The
analysis of evolutionary relationship showed that the four S. scherzeri populations can be divided into two groups
of Yangtze River system and the Pearl River. Overall the data provide significant information for the genetic and
evolutionary status of sinipercids upon adapting to different environments, and for genetic conservation and
selective breeding of these fish species in fishery and aquaculture.
Keywords: Mitogenomes, sinipercid, phylogenetic analyses, point mutation.
