Length‐weight relationships of five fish species in Tibet, southwest China

Length-weight relationships (LWR) were evaluated for five species: Schizothorax integrilabiatus (Wu etal., 1992); Shizopygopsis stoliczkai Steindachner, 1866; Gymnocypris chui Tchang, Yueh & Hwang, 1964; Gymnocypris scleracanthus Tsao, Wu, Chen & Zhu, 1992; and Triplophysa tibetana (Regan, 1905). A total of 567 specimens were collected whereby S.integrilabiatus was caught with 12-volt electric fishing gear (water depth, 1m) in Buqun Lake in May 2015. Both G.chuiand G.scleracantus were caught with 12-volt electric fishing gear (water depth,1m) and set gillnets (mesh size 3cm) in Lange Lake in July 2015, S.stoliczkhaiwas caught with 3cm mesh size set gillnets in Shiquan River in August 2015, T.tibetana was caught with 12V electric fishing gear in the Zhongba reach of the Yarlung Zangbo River in August 2015. This study provides the first published length-weight references on LWR for the five species. New maximum total lengths were recorded for three species, including Shizopygopsis stoliczkai, Gymnocypris chui, and Gymnocypris scleracanthus.
