Summary Length – weight relationships were estimated for five endemic fish species in the upper Yangtze River: Platysmacheilus nudiventris Luo, Le & Chen, 1977, Xenophysogobio nudicorpa (Huang & Zhang, 1986), Homatula potanini (Günther, 1896), Leptobotia rubrilabris (Dabry de Thiersant, 1872), and Euchiloglanis kishinouyei Kimura, 1934. The a values ranged from 0.0079 to 0.0134, and b values from 2.833 to 3.081. These five endemic species are rare, small and difficult to find and capture. Thus the sampling period was lengthy, from May 2010 to May 2014. A total of 718 specimens were available for analysis, and the length – weight relationships are the first reports for these five endemic fish species.
