河南省大吻鱥属鱼类分类现状厘定
- 分享到:
摘要:
河南省鱼类资源调查队在河南省鱼类资源普查时,采集到两种大吻鱥属鱼类,采用传统形态学结合分子系统学方法确定其为尖头大吻鱥和拉氏大吻鱥.由于拉氏大吻鱥和尖头大吻鱥形态上相似度较高,结合我们采集的两个物种现有数据分析发现,以往鉴别特征并不能完全区分这两个物种,因而本文对尖头大吻鱥和拉氏大吻鱥的主要形态鉴定特征、分布区域、生存环境及生活习性等方面做了进一步分析厘定,对分布于河南省的大吻鱥属鱼类做了系统比较总结,修正了现有该属鱼类的主要鉴别特征及在我省的分布情况,标本保存于betway官方app 水产学院鱼类标本室.
Two species of Rhynchocypris fishes were collected during an investigation on fish resources.The specimens were identified as Rhynchocypris oxycephalus and Rhynchocypris lagowskii based on morphological and molecular data.Because of the high morphological similarity between the Rhynchocypris oxycephalus and Rhynchocypris lagowskii,combined with the data available from the two species we collected, we found that the previous identification characteristics could not completely distinguish the two species.Therefore,the main morphological characteristics,distribution area,living environment and living habits of two species of fishes were further analyzed.This study makes a systematic comparison of the Rhynchocypris distributed in Henan Province,revises the main identification characteristics and its distribution of Rhynchocypris in Henan province.The collected specimens are preserved in Fish Specimen Library of College of Fisheries,Henan Normal University.
