Abstract

Summary: Length‐weight relationships (LWRs) were estimated for two fish species from the Jialing River in southwestern China. Specimens were landed seasonally from January 2014 to December 2015 at three locations in the Jialing River and four times fishing activities were occurred in each season at each location. Fishing gear used for sampling included 2, 5, 8 and 10 cm mesh gill nets (50 m long × 1.5 m high). This study presents the LWRs for two species of Culter oxycephaloides Kreyenberg & Pappenheim, 1908 and Gnathopogon herzensteini (Günther, 1896). The LWRs were estimated using the equation W = aL b . The b values were 2.6513 and 3.2245 for C. oxycephaloides and G. herzensteini respectively . The constant values of a were determined as 0.0330 for C. oxycephaloides and 0.0111 for G. herzensteini . This result provides primary data for future fish research and conservation regarding these species in the Jialing River.
