Abstract. Length–weight relations (LWRs) were estimated for 46 fish species representing 8 families and 29 genera from the lower sections of Jialing River, a tributary of Yangtze River basin, south-western China: Opsariichthys bidens Günther, 1873; Squaliobarbus curriculus (Richardson, 1846); Ancherythroculter kurematsui (Kimura, 1934); Chanodichthys mongolicus (Basilewsky, 1855); Hemiculter tchangi Fang, 1942; Pseudolaubuca sinensis Bleeker, 1864; Pseudolaubuca engraulis (Nichols, 1925); Parabramis pekinensis (Basilewsky, 1855); Xenocypris davidi Bleeker, 1871; Xenocypris fangi Tchang, 1930; Hypophthalmichthys nobilis (Richardson, 1845); Hypophthalmichthys molitrix (Valenciennes, 1844); Sarcocheilichthys nigripinnis (Günther, 1873); Sarcocheilichthys sinensis Bleeker, 1871; Squalidus argentatus (Sauvage et Dabry de Thiersant, 1874); Coreius heterodon (Bleeker, 1864); Coreius guichenoti (Sauvage et Dabry de Thiersant, 1874); Rhinogobio typus Bleeker, 1871; Rhinogobio cylindricus Günther, 1888; Saurogobio dabryi Bleeker, 1871; Saurogobio gymnocheilus Lo, Yao et Chen, 1998; Gobiobotia filifer (Garman, 1912); Xenophysogobio boulengeri (Tchang, 1929); Onychostoma simum (Sauvage et Dabry de Thiersant, 1874); Spinibarbus sinensis (Bleeker, 1871); Procypris rabaudi (Tchang, 1930); Parabotia fasciata Dabry de Thiersant, 1872; Parabotia bimaculata Chen, 1980; Leptobotia elongata (Bleeker, 1870); Leptobotia taeniops (Sauvage, 1878); Leptobotia rubrilabris (Dabry de Thiersant, 1872); Leptobotia microphthalma Fu et Ye, 1983; Jinshaia sinensis (Sauvage et Dabry de Thiersant, 1874); Pseudobagrus vachellii (Richardson, 1846); Pseudobagrus pratti (Günther, 1892); Tachysurus nitidus (Sauvage et Dabry de Thiersant, 1874); Tachysurus dumerili (Bleeker, 1864); Hemibagrus macropterus Bleeker, 1870; Liobagrus nigricauda Regan, 1904; Liobagrus marginatus (Günther, 1892); Silurus asotus Linnaeus, 1758; Silurus meridionalis Chen, 1977; Glyptothorax fokiensis (Rendahl, 1925); Glyptothorax sinensis (Regan, 1908); Siniperca chuatsi (Basilewsky, 1855); Siniperca knerii Garman, 1912. Data were monthly collected from May 2013 to October 2016. The values of coefficient a ranged from 0.0046 to 0.0237, and the values of exponent b ranged from 2.66 to 3.26. The length–weight relations of two species have not been previously reported.
