摘要
扁圆吻鲴(Distoechodon compressus)对调节和稳定水体生态系统发挥着重要作用。鉴于扁圆吻鲴野生资源的衰退及其生态净水功能,福建省龙岩市大力开展扁圆吻鲴增殖放流工作,以恢复其在各主要水域的种群数量,实现预期效果。本文通过分析2018—2021年度扁圆吻鲴增殖放流数据,从增殖放流品种选择的合理性、苗种批量繁育技术体系和增殖放流关键技术环节等角度展开分析和讨论,并对该领域的发展和研究方向进行展望,以期为扁圆吻鲴的增殖放流工作提供借鉴和参考。
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.
