In September 2009, fish resources were investigated in Shaanxi Kuyu aquatic resources reserve, by quadrat sampling method. Four fish species, namely, Paracobitis variegates, Triplophysa minxianensis, Phoxinus lagowskii and Scaphesthes macrolepis were found in the reserve. Fishes had different distributional altitudes in this area. The dominant species was P. Lagowskii, and the biggest individual was of S. Macrolepis. In intermediate altitude of 950 ～1200 meter of the reserve, there were more fish species, greater biodiversity, richer fish resources and greater average body weight, and there emerged the biggest individual of every species. As the main protected object, T. Minxianensis had the least quantity and biomass, and its protection should be enhanced.%2010年9月采用样方法对陕西库峪岷县高原鳅水产种质资源保护区的鱼类进行了调查.共调查到4种鱼类,即红尾副鳅(Paracobitis variegates)、岷县高原鳅(Triplophysa minxianensis)、拉氏(鲈)(Phoxinus lagowskii)和多鳞铲颌鱼(Scaphesthes macrolepis).结果显示各种鱼类的分布海拔表现出差异性；保护区鱼类的优势种是拉氏(鲈)；个体最大的鱼类是多鳞铲颌鱼.鱼类种类多、多样性高的区域均出现在保护区的950 ～ 1200m的中海拔区域；同时该区域的鱼类资源量较高、平均体重较大,最大个体的鱼类也出现于此区域.作为保护区的主要保护对象,岷县高原鳅无论数量或生物量均最少,应进一步加强保护.
