Summary The length–weight relationships ( LWR s) were determined for two native cyprinid fishes: Poropuntius opisthopterus (Wu, 1977) and Raiamas christyi (Boulenger, 1920) collected from the upper reaches of Nujiang River (31°33′29″N; 92°55′58″E), Southwest of China. A total of 162 specimens were collected quarterly between March 2015 and November 2016. Fish were sampled by electrofishing in 12 wadable sites with maximum water depth 60–70 cm. The b values parameter in the length–weight relationship equations were calculated as 2.90 for P. opisthopterus and 3.45 for R. christyi . This study represents a new maximum standard length record for P. opisthopterus .
