长江上游青衣江支流周公河鱼类资源现状
Status of Fish Resources in the Zhougong River, a Tributary of the Qingyi River

中文摘要：为了解长江上游青衣江一级支流周公河的鱼类资源现状，于2015年4月-2016年2月对周公河18个采样点进行了5次调查，共采集鱼类4 924尾，隶属于3目8科27属34种。其中，鲤形目Cypriniformes 20属24种，鲇形目Siluriformes 6属8种，鲈形目Perciformes 1属2种；鲤形目中鲤科Cyprinidae鱼类最多，共15种，占总种数的44.12%。四川省重点保护鱼类有重口裂腹鱼 Schizothorax （ Racoma） davidi 1种，长江上游特有鱼类9种，列入《中国脊椎动物红色名录》的鱼类有重口裂腹鱼（濒危EN）、齐口裂腹鱼 S.（ S.） prenanti（易危VU）和白缘？ Liobagrus marginatus（易危VU）。周公河现有分布的鱼类以小型种类为主，钝吻棒花鱼 Abbottina obtusirostris和宽鳍鱲 Zacco platypus为优势种。梯级水电开发可能对周公河鱼类资源造成了不利影响。
英文摘要：Fish resources in the Zhougong River were surveyed at 18 sampling sites for 5 times from April 2015 to February 2016. A total of 4 924 individuals belonging to 34 species, 27 genera, 8 families and 3 orders were collected and identified. There were 20 genera including 24 species in Cypriniformes, 6 genera including 8 species in Siluriformes, and 1 genus including 2 species in Perciformes. The number of species in Cyprinidae was the largest, which occupied 44.12% of the total species number. Among the 34 species, Schizothorax ( Racoma) davidi was one of the key protected animals in Sichuan province, and 9 were endemic to the upper reaches of the Yangtze River. In addition, S. ( Racoma) davidi was listed as endangered, and S. ( S.) prenanti and Liobagrus marginatus were listed as vulnerable in Red List of China's Vertebrates. Most of the fish species living in the Zhougong River were found to be small-sized, and among of which, Abbottina obtusirostris and Zacco platypus were the dominant. Dam constructions on the Zhougong River might have resulted in negative impacts on fishes. 2018,37(5): 592-600 收稿日期：2018-01-30 DOI：10.11984/j.issn.1000-7083.20180042 分类号：Q959.4;S932.4 基金项目：四川省水产局科研项目“周公河鱼类资源调查” 作者简介：周宇(1994-),女,硕士研究生,研究方向:动物生态学,E-mail:18380385816@163.com *通讯作者：宋昭彬,教授,博士生导师,E-mail:zbsong@scu.edu.cn 参考文献： 陈宜瑜. 1998. 中国动物志 硬骨鱼纲 鲤形目(中卷)[M]. 北京:科学出版社. 褚新洛. 1999. 中国动物志 硬骨鱼纲 鲇形目[M]. 北京:科学出版社. 丁瑞华. 1994. 四川鱼类志[M]. 成都:四川科学技术出版社. 蒋红, 谢嗣光, 赵文谦, 等. 2007. 二滩水电站水库形成后鱼类种类组成的演变[J]. 水生生物学报, 31(4):532-539. 蒋志刚, 江建平, 王跃招, 等. 2016. 中国脊椎动物红色名录[J]. 生物多样性, 24(5):500-551. 乐佩琦. 2000. 中国动物志 硬骨鱼纲 鲤形目(下卷)[M]. 北京:科学出版社. 茹辉军, 张燕, 李云峰, 等. 2016. 雅砻江支流安宁河鱼类群落组成及资源现状[J]. 水生态学杂志, 37(5):68-74. 若木, 王鸿泰, 殷启云, 等. 2001. 齐口裂腹鱼人工繁殖的研究[J]. 淡水渔业, 31(6):3-5.
