Domestication has altered a variety of traits within the Eurasian perch ( Perca fluviatilis ), including phenotypic, physiological and behavioral traits of Eurasian perch ( Perca fluviatilis ). Little is known, however, about the genetic changes between domesticated and wild Eurasian perch. In this study, we assembled a high-quality de novo reference transcriptome and identified differentially expressed genes between wild and domesticated Eurasian perch. A total of 113,709 transcripts were assembled, and 58,380 transcripts were annotated. Transcriptomic comparison revealed 630 differentially expressed genes between domesticated and wild Eurasian perch. Within domesticated Eurasian perch there were 412 genes that were up-regulated including MHCI , MHCII , chia , ighm within immune system development. There were 218 genes including try1 , ctrl , ctrb , cela3b , cpa1 and cpb1 , which were down-regulated that were associated with digestive processes. Our results indicated domestication drives the changes of immune and digestive system of Eurasian perch. Our study not only provide valuable genetic resources for further studies in Eurasian perch, but also provide novel insights into the genetic basis of physiological changes in Eurasian perch during domestication process.
