为了有效区分野外采集和人工繁育胭脂鱼（ Myxocyprinus asiaticus）群体，对四川省水产研究所（ SCC）、宜宾珍稀水陆生动物研究所（ YBC ）、重庆市万州水产研究所（ WZC ）的150尾人工繁育胭脂鱼和长江干流泸州（ LZW）、木洞（ MDW）、万州（ WZW）的112尾野外采集胭脂鱼进行了形态学差异分析。主成分分析、判别分析、聚类分析和形态学差异系数分析显示： WZC和YBC形态较相似，而与SCC在背鳍长/体长、尾鳍上叶长/体长、眼径/体长等特征上区别明显； WZW与MDW形态相似，而与LZW在臀鳍基后尾柄高/体长、吻长/体长、头长/体长、眼后头长/体长、头高/体长等特征上有区别； WZW与SCC形态相似度较大，而MDW与WZC、 YBC形态相似度较大。结果表明通过形态学分析无法有效区分野外采集和人工繁育胭脂鱼群体。
為瞭有效區分野外採集和人工繁育胭脂魚（ Myxocyprinus asiaticus）群體，對四川省水產研究所（ SCC）、宜賓珍稀水陸生動物研究所（ YBC ）、重慶市萬州水產研究所（ WZC ）的150尾人工繁育胭脂魚和長江榦流瀘州（ LZW）、木洞（ MDW）、萬州（ WZW）的112尾野外採集胭脂魚進行瞭形態學差異分析。主成分分析、判彆分析、聚類分析和形態學差異繫數分析顯示： WZC和YBC形態較相似，而與SCC在揹鰭長/體長、尾鰭上葉長/體長、眼徑/體長等特徵上區彆明顯； WZW與MDW形態相似，而與LZW在臀鰭基後尾柄高/體長、吻長/體長、頭長/體長、眼後頭長/體長、頭高/體長等特徵上有區彆； WZW與SCC形態相似度較大，而MDW與WZC、 YBC形態相似度較大。結果錶明通過形態學分析無法有效區分野外採集和人工繁育胭脂魚群體。

Morphological differences of Myxocyprinus asiaticus between hatchery-breeding samples ( collected from Sichuan Fisheries Research Institute ( SCC) , Yibin Rare Aquatic Animal Research Institute ( YBC) and Chongqing Wanzhou Fish-eries Research Institute ( WZC ) ) , and wild-caught samples ( collected from the ranges of Luzhou ( LZW ) , Mudong (MDW) and Wanzhou (WZW) at the main stream of the Yangtze River ) were analyzed.The results of principal compo-nent analysis , discriminant analysis , cluster analysis and morphological variation coefficient analysis showed that , similar morphological characters were observed between WZC and YBC samples , but SCC was different from them in the length of dorsal fin/body length , lobe length of caudal fin/body length and eye diameter/body length; LZW was different from WZW and MDW samples in the tail height behind anal fin base /body length , snout length/body length , head length/body length, head length behind eyes/body length and height of head/body length; WZW sample was morphologically similar with SCC sample , while MDW was morphologically similar with WZC and YBC samples .In conclusion , no obvious mor-phological differences were found between the hatchery-breeding and wild-caught aggregates of M.asiaticus in the present survey.
