Abstract Length‐weight relationships were determined for three fish species ( Platytropius yunnanensis He, Huang & Li, 1995, Schizothorax lantsangensis Tsao, 1964 and Schizothorax yunnanensis Norman, 1923) from southwestern China. Specimens were collected using gillnets (20 × 2 m, mesh‐size 5 mm; soaking depth: 50–150 cm; exposure time: 10 hr/day) and electroshock fishing techniques quarterly from May 2016 to June 2017. Standard length (SL, nearest 0.1 cm) were determined as well as weight (nearest 0.1 g). The a values ranged from 0.01385 ( S. lantsangensis ) to 0.04155 ( P. yunnanensis ), the b values ranged from 2.68 ( P. yunnanensis ) to 2.98 ( S. lantsangensis ) and the coefficient of variation ( r 2 ) ranged from 0.957 ( P. yunnanensis ) to 0.963 ( S. yunnanensis ).
