Summary This study presents length‐weight relationships ( LWR s) for two sympatric species of the subfamily Schizothoracinae (Cyprinidae), Gymnocypris chui and G. scleracanthus , captured in Lake Langcuo in Tibet, China. A total of 193 specimens were collected in June and July of 2014 and 2015 using gill nets of different mesh sizes (mesh size: 2 × 2 cm, 3 × 3 cm). Specimens included 76 G. chui and 117 G. scleracanthus . The values of parameter b in the LWR s equations were estimated as 2.875 for G. chui , and 2.773 for G. scleracanthus , respectively. These are the first LWR s records for the two sympatric species.
