Summary Length‐weight relationships ( LWR s) were estimated for three small indigenous fish species, ( Sinogastromyzon szechuanensis , Sinogastromyzon sichangensis and Sinocrossocheilus labiatus ) in the upper Yangtze River, China. Samples were collected using three types of local traditional fishing gears, including gill nets (mesh size: 1 cm), fish cages (mesh size: 0.5 cm), and electrofishing techniques ( CWB ‐2000 P, 12V, 250 Hz), in April, July and October 2013 and 2014, and April and October 2016. The sample size for each species were gathered separately, with 100 for S. szechuanensis , 381 for S. sichangensis and 49 for S. labiatus from National Nature Reserve for rare and endemic fishes of the upper Yangtze River, China. The length‐weight relationship parameter values of b were calculated as 2.986 for S. szechuanensis ( b : 2.854–3.118), and 3.284 for S. sichangensis ( b : 3.209–3.359) and 3.119 for S. labiatus ( b : 2.911–3.326). The primary data will be meaningful for further research about sustainable development and scientific management of fishery resources of the upper Yangtze River.
