Fish genomic research: Decade review and prospect

This paper reviews the process of fish genomic research in China, which started with scratch and then developed from small to large. The important progress and findings regarding BAC library construction, high-density genetic linkage map construction, genome sequencing and fine mapping, genome selection and genome editing by Chinese scientists were introduced. Based on the comparison with the international progress in this field, it was pointed out that Chinese scientists followed the international research from 2008 to 2013.While from 2014 to 2018, China’s fish genomic study has accelerated development and has been catching up. Just during the past five years, the top journals Nature and Nature Genetics have published several papers of genome sequencing and fine mapping in important aquatic fishes from China, such as half-smooth tongue sole, common carp, grass carp, Japanese flounder and sea horse. The progress has brought China’s fish genomic research from full-scale following in the past to the present coexistence of following, running side-by-side, and even leading in some research directions and species. In the meanwhile, we summarized the current shortcomings and problems in fish genomic research and application field, and prospected the future development of aquatic genomic research in China.
