Length-weight relationships of eight fish species from the upper reaches of the Yangtze River, southwest China

Abstract

Summary The length–weight relationships are reported for eight fish species, Hemimyzon yaotanensis (Fang, 1931), Leptobotia taeniops (Sauvage, 1878), Liobagrus nigricauda Regan, 1904, Pseudobagrus crassilabris (Günther, 1864), Pseudobagrus pratti (Günther, 1892), Pseudolaubuca engraulis (Nichols, 1925), Rhinogobio cylindricus Günther, 1888, and Sinogastromyzon szechuanensis Fang, 1930. Specimens were collected from the upper reaches of the Yangtze River, southwest China during November 2010 to December 2015. Fish were sampled by various types of fishing gear (mesh size: 1–12 cm) and baited hooks. Compared to the information in FishBase, length–weight relationships for two fish species and seven maximum lengths were presented here for the first time.
