Gymnocypris chui Tchang, Yueh & Hwang, 1964 and Gymnocypris scleracanthus Tsao, Wu, Chen & Zhu, 1992 from Lake Langcuo, Qinghai‐Tibet Plateau

This study presents length-weight relationships (LWRs) 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: 2x2cm, 3x3cm). Specimens included 76 G.chui and 117 G.scleracanthus. The values of parameter b in the LWRs equations were estimated as 2.875 for G.chui, and 2.773 for G.scleracanthus, respectively. These are the first LWRs records for the two sympatric species.
