Length-weight relationships for nine fish species in the Three Gorges Reservoir

Length-weight relationships (LWRs) were determined for nine fish species occurring in the Three Gorges Reservoir(28 degrees 56-31 degrees 44N, 106 degrees 14-111 degrees 28E). Fish were collected using gill nets, including two of 1.0m depth, 100m long, and mesh size of 0.5cm; two of 1.0m deepth, 150m long, and mesh size of 2.0cm; and one of 1.5m deepth, 100m long, and mesh size of 6.0cm. Gill nets were set over night including different habitats (riffles and pools, vegetated and non vegetated zones) from seven sites seasonallyfrom January 2014 to January 2018. The first LWR reference for Jinshaia abbreviata (Gunther, 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.
