Length-weight relationships of five fish species from the Yalong and Wujiang rivers (tributaries of Yangtze River, China)

Summary Length‐weight relationships (LWRs) were determined for five endemic fish species from the Yalong and Wujiang rivers (tributaries of the Yangtze River, China): Folifer brevifilis (Peters, 1881), Pelteobagrus ussuriensis (Dybowski, 1872), Schistura fasciolata (Nichols & Pope, 1927), Triplophysa daqiaoensis (Ding, 1993) and Triplophysa orientalis (Herzenstein, 1888). Samples were obtained between April 2004 and July 2014 using various fishing gear (set nets, drift gill nets, fish cages, hook and electro fishing). For each specimen from each species the sample size was recorded, total length and weight were measured and the LWR determined. Further, the 95% confidence intervals of a and b, and coefficient of correlation were estimated. Prior to this study, the LWRs for these five species were unknown.
