摘要: 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.
