Length–weight relationships for four fish species upstream in the Minjiang River,southeastern China

Length–weight relationships were determined for four fish species (Hemibarbus labeo Pallas, 1776; Tachysurus nitidus Sauvage & Dabry de Thiersant, 1874; Pseudobagrus vachelli Richardson, 1846; Glossogobius olivaceus Temminck & Schlegel, 1845) upstream in the Minjiang River in Fujian Province, southeastern China. Samples were collected employing various fishing gear in 2012–2013. The present report is the first record of the length–weight relationships for these species.     

Length–weight relationships for three fish species from the Yalong River,southwestern China

Length–weight relationships were determined for three fish species: Gymnodiptychus pachycheilus (Herzenstein, 1892), Discogobio yunnanensis (Regan, 1907), and Triplophysa pseudostenura (He, Zhang & Song, 2012). Samples were collected from the Yalong River, southwestern China using fishing gear (gillnets, 30 × 15 m, mesh‐size 5 mm) and electroshock fishing (CWB‐2000 P, 12 V, 250 HZ) in June 2007. Prior to this study, length–weight relationships for these three species were unknown. For two of the species [Discogobio yunnanensis (Regan, 1907) and Triplophysa pseudostenura (He, Zhang & Song, 2012)], new maximum standard lengths not yet reported in the scientific literature were noted.
