Length–weight relationships (LWRs) were estimated for seven fish species from Guijiang River in Guangxi region, China. Fish samples were collected by electrofishing (CWB‐2000P, China; 12 V import, 250 V export) and gill nets (length 12 m, height 0.8 m, mesh 10 mm) in January, April, July and October, 2015. The electrofishing was conducted about 2 km long within 2 hr, and ten gill nets were settled over night at each sampling site. All fish were identified and measured in the field immediately. All values for the allometric coefficient (b) of the length–weight equations were within the expected range (2.50–3.50). All values for the coefficient of determination (r²) were above .95 and thus the estimates can be considered reliable.
