Abstract
Pike perch (Sander canadensis) is a member of the largest order of Osteichthyes, Perciformes, and is an important ecological and economic freshwater species, which distributes in Ili River and Ergis River of Xinjiang Province, China. In this study, we sequenced the whole mitochondrial genome of pike perch, and analyzed the similarity with its related species. The mitochondrial genome of S. canadensis is 16,542 bp in length with 55.05% AT content, contained 13 protein coding genes, 22 tRNA genes, 2 ribosomal genes and an 892 bp non-coding region. In control region, 6 CSBs (CSB-1, CSB-2, CSB-3, CSB-D, CSB-E and CSB-F), one potential TAS and one poly-T region were identified. Comparing all protein-coding genes and whole genome sequence with 4 species of Perciformes (three species of Percidae, Perca flavescens. Percina macrolepida. Etheostoma radiosum and one outgroup Oreochromis sp. red tilapia), ND3 gene has the highest mutation rate, and S. canadensis has higher similarity with Perca flavescens than others. The mitochondrial genomic sequence will help us to study the conservation genetic and evolution of Percidae.
