Length-weight relationships of eleven fish species from the middle reaches of Jinsha River, southwest China

Summary Length‐weight relationships (LWRs) were determined for eleven endemic fish species [Coreius guichenoti (Sauvage & Dabry de Thiersant, 1874), Glyptothorax sinensis (Regan, 1908), Leptobotia elongata (Bleeker, 1870), Leptobotia taeniops (Sauvage, 1878), Pseudobagrus crassilabris (Günther, 1864), Rhinogobio ventralis (Sauvage & Dabry de Thiersant, 1874), Saurogobio dabryi (Bleeker, 1871), Schizothorax chongi (Fang, 1936), Schizothorax kozlovi (Nikolskii, 1903), Schizothorax prenanti (Tchang, 1930) and Schizothorax wangchiachii (Fang, 1936)] from the middle reaches of the Jinsha River in southwest China. Samples were obtained between May 2004 and July 2013 using various types of fishing gear and electroshock fishing techniques. For each species, the sample size, length range, weight range, LWR, 95% confidence intervals of a and b, and coefficient of correlation were determined. Prior to this study, the LWRs for four species (P. crassilabris, S. chongi, S. kozlovi and S. prenanti) were unknown.
