In recent years,advances in high-throughput sequencing technique and capacity of big data analysis have facilitated genomics research in many species.Genome sequencing,single nucleotide polymorphism(SNPs) identification and population transcriptomics are conducive to understanding the evolutionary progress and regulatory mechanisms of genes related to adaptive traits in organisms,which poses great significance to the theoretical research and productive practice.Furthermore,population genomics of marine fishes can deepen the understanding of important microevolution events,such as genetic differentiation,hybridization and speciation.Therefore,the related research contributes to better understanding of the evolutionary process of marine organisms and provides theoretical evidences for the development of aquaculture industry and management and protection of marine fishery resources.
