Summary Length–weight relationships ( LWR s) for five fish species which were captured by trap‐nets and gillnets (major mesh size: 1–10 cm) from the middle Yangtze River, China (29°47′ – 29°26′N; 112°51′ – 113°08′E) were determined in September 2017. These were Acheilognathus hypselonotus (Bleeker, 1871), Culter oxycephaloides Kreyenberg & Pappenheim, 1908, Distoechodon tumirostris Peters, 1881, Sarcocheilichthys nigripinnis (Günther, 1873) and Micropercops swinhonis (Günther, 1873). The LWR s were estimated using the logarithmic form of the formula W  =   a  ×   L b . The b value ranged from 2.879 for A. hypselonotus to 3.285 for M. swinhonis . LWR s for four fish species and new maximum lengths for three species are presented to FishBase for the first time.
