2013年8月和12月，对陕西米仓山国家级自然保护区鱼类资源进行了调查。结果显示：保护区有鱼类1目（鲤形目）2科（鲤科 Cobitidae、鳅科 Cyprinidae）8属9种，其中鲤科5种，鳅科4种，保护区优势种为拉氏（Phoxinus lagowskii）和红尾荷马条鳅（Homatula variegata），稀有种为宽口光唇鱼（Acrossocheilus monticolus）和马口鱼（Opsariichthys bidens）；鱼类物种多度格局近似正态分布，海拔900～1000 m 区域生物多样性最丰富，海拔1000 m以上鱼类物种数急剧下降。总体而言，陕西米仓山保护区鱼类组成相对简单，群落结构脆弱，多样性程度不高，近年来渔业资源有所下降。

Fish resources were investigated in Shaanxi Micangshan National Nature Reserve in August and December of 2013.The results showed that 9 species belonged to 8 genus, 2 families (Cobitidae and Cyprinidae), 1 order (CYPRINI-FORMES) were found.The dominant species were Phoxinus lagowskii Dybowsky and Homatula variegata(Sauvage et Dab-ry).Acrossocheilus monticolus and Opsariichthys bidens were rare species.A nearly normal distribution of fish species abun -dance pattern was found in this reserve area .There were more fish species and higher biodiversity in the area with height ranged from 900 meters to 1000 meters than other areas in the reserve region.The number of species decreased sharply in the areas with altitude over 1000m.The results indicated low stability of fish community and diversity in Shaanxi Micangshan National Nature Reserve, downwards tendency in fishery resources in recent years .
