| Abstract: | This study provides the first report of length–weight relationships (LWRs) for Pseudogyrinocheilus prochilus (Sauvage & Dabry de Thiersant, 1874) and Jinshaia sinensis (Sauvage & Dabry de Thiersant, 1874) collected from the middle reaches of the Jinsha River, southwest China. Samples were obtained between June 2005 and November 2006. A total of 491 specimens belonging to two fish species were analyzed. LWRs were W = 0.0170L2.970 (r2 = 0.980) for P. prochilus and W = 0.0194L2.849 (r2 = 0.977) for J. sinensis. Prior to this study, the LWRs for P. prochilus were unknown. In addition, new maximum size for J. sinensis was provided. |
