Abstract

Length-weight relationships (LWRs) were evaluated for three endemic fish species (Sinibrama taeniatus Nichols, 1941; Ancherythroculter nigrocauda Yin & Wu, 1964; and Acrossocheilus monticola Günther, 1888) from the upper reaches of the Yangtze River, southwestern China. Samples were collected using gill nets (25 × 12 m, mesh-size 2.0 cm) and fishing cages (0.5 × 0.5 × 10 m, mesh-size 1.0 cm) as well as by electroshock (CWB-2000 P, 12 V, 250 Hz), from July to September in 2013–2016. Prior to this study, the LWRs for these three species (S. taeniatus, A. nigrocauda and A. monticola) were unknown. In addition, new maximum size for A. nigrocauda and A. monticola were provided.
