2015年10月,河南省鱼类资源调查队在河南省林州市进行鱼类资源普查时,采集到30尾刺鱼目Gasterosteiformes鱼类,综合采用形态学和分子系统学的方法确定其为中华多刺鱼Pungitius sinensis,为河南省新纪录种,标本保存于河南师范大学水产学院鱼类标本室。本文对该鱼的主要鉴定特征、分布区域、可能的来源、生存环境等做了初步分析。该鱼在我国北方(辽宁、黑龙江、吉林、天津、河北等省市)及韩国、日本北方均有分布,记录最南分布区域为北京市,为北京市二级保护鱼类。此次报道进一步扩大了该鱼最南端分布界限,为进一步开展该鱼的基础研究提供了重要参考资料。
In October 2015, when fish survey team of Henan Province conducted a survey of fish resources in Linzhou City, Henan Province, 30 fish species of Gasterosteiformes were collected and morphologically and molecularly systematically identified as China Pungous sinensis, a new record species of Henan province, was deposited in the Fish Specimen Laboratory of Fisheries College of Henan Normal University. In this paper, the main characteristics of the fish identification, distribution area, possible sources, living environment made a preliminary analysis. The fish in North China (Liaoning, Heilongjiang, Jilin, Tianjin, Hebei and other provinces and cities) and South Korea, Japan North are distributed, the most southern distribution area for the record Beijing, Beijing secondary protected fish. The report further expanded the southernmost distribution of the fish, providing an important reference for further carrying out the basic research of the fish.
