Summary The length–weight relationships (LWRs) were determined for five fish species from the Beijiang River in China. Fishes were caught by gill nets (mesh sizes: 5, 7, 9 cm), and cage nets (mesh sizes: 0.5 cm) from April to September 2018. Length–weight relationships of four species were unknown to FishBase, and new records of maximum lengths are given for two species, one of which, Ancherythroculter lini , is endemic species of the Pearl River. All length–weight relationships were highly significant on a log scale with the coefficient of determination ( r 2 ) values ranged from 0.939 to 0.991. Values of b were within the expected range, varied from 2.935 for A. lini to 3.414 for Parasinilabeo assimilis .
