Abstract: Chinese sturgeon (Acipenser sinensis), an endemic fish species in China, is in endangered status due to human activities. It was listed in the International Union for the Conservation of Nature and Natural Resources (IUCN) Red List as critically endangered species in 2010. In this review, the present situation of resources, characteristics and swimming ability of Chinese sturgeon were introduced. The main methods of conservation for this species were artificial propagation, fishery enhancement and release, and the construction of reserve. Achievements and difficulties for artificial propagation of Chinese sturgeon in past 30 years were overviewed. We summarized the research progress on fishery enhancement and release of Chinese sturgeon, and the short-term effect was hard to evaluate due to the difficulty of marked recapture of Chinese sturgeon. In addition, the significance of protection reserve construction to Chinese sturgeon was discussed. This review will provide some references for further study.
