| Abstract: | Length‐weight relationships (LWRs) were determined for nine fish species occurring in the Three Gorges Reservoir(28°56′–31°44′N, 106°14′–111°28′E). Fish were collected using gill nets, including two of 1.0 m depth, 100 m long, and mesh size of 0.5 cm; two of 1.0 m deepth, 150 m long, and mesh size of 2.0 cm; and one of 1.5 m deepth, 100 m long, and mesh size of 6.0 cm. Gill nets were set over night including different habitats (riffles and pools, vegetated and non vegetated zones) from seven sites seasonally from January 2014 to January 2018. The first LWR reference for Jinshaia abbreviata (Günther, 1892), and Triplophysa tanggulaensis (Zhu, 1982) and new maximum lengths for other seven species are provided when comparing with records given in the international electronic databank FishBase (Froese & Pauly, FishBase. World Wide Web electronic publication, 2018). |
