Abstract: Distoechodon compressus plays an important role in regulating and stabilizing the water ecosystem.In view of the decline of wild resources and its ecological water purification function,stock enhancement of Distoechodon compressus was carried out by Longyan City to restore its population in each main water area and achieve the expected effect.Based on the analysis of stock enhancement data from 2018 to 2021,the variety selection of stock enhancement and the artificial propagation of D.compressus were analyzed and discussed in this paper.Meanwhile,the key technologies,development and research direction of this field were also prospected,in order to provide reference for stock enhancement of D.compressus.
