中华鲈科是东亚特有的淡水鲈形目鱼类，共有12种，它们的系统发育位置一直困扰着几代分类学家。本研究克隆并测序了3种华鲈（Siniperchuatsi，S. p.）kneri和S. scherzeri）来表征和比较它们的线粒体基因组。线粒体基因组的S。chuatsi，S. kneri和S. Scherzeri的长度分别为16，496、17，002和16，585 bp。这三个线粒体基因组的组织结构与其他鱼类线粒体基因组的组织结构相似，包含37个基因（13个蛋白质编码基因，2个核糖体RNA和22个转运RNA）和一个主要的非编码控制区。在这3种鱼类的13个蛋白质编码基因中，在同一条链上发现了3个阅读框重叠。在S. CSB-3的末端有一个81 bp的串联重复序列簇。谢尔泽里控制区。这三种鱼类线粒体基因组的完整序列为鱼类和其他脊椎动物的进化研究提供了参考。
The sinipercids are a group of 12 species of freshwater percoid fish endemic to East Asia and their phylogenetic placements have perplexed generations of taxonomists. We cloned and sequenced the complete mitochondrial DNA (mtDNA) of three sinipercid fishes (Siniperca chuatsi, S. kneri, and S. scherzeri) to characterize and compare their mitochondrial genomes. The mitochondrial genomes of S. chuatsi, S. kneri, and S. scherzeri were 16,496, 17,002, and 16,585 bp in length, respectively. The organization of the three mitochondrial genomes is similar to those reported from other fish mitochondrial genomes, which contains 37 genes (13 protein-coding genes, 2 ribosomal RNAs, and 22 transfer RNAs) and a major non-coding control region. Among the 13 protein-coding genes of all the three sinipercid fishes, three reading-frame overlaps were found on the same strand. There is an 81-bp tandem repeat cluster at the end of CSB-3 in the S. scherzeri control region. The complete mitochondrial genomes of the three sinipercids should be useful for the evolutionary studies of sinipercids and other vertebrate species.
