Length–weight relationships of ten fish species from the Jingjiang reach of the Yangtze River, China

The length–weight relationships (LWRs) were estimated for ten fish species from the Jingjiang reach of the Yangtze River, China. Samples were collected using a combination set-net consisting of a 40-meter net wall (mesh size: 1.8 cm) and two fyke nets (mesh size: 0.9 cm) on the 1st, 11th and 21st of each month from January 2012 to December 2017. The b values of all species were within the expected ranges, varying between 2.849 and 3.292. This study provides the LWR parameters for Distoechodon tumirostris, Microphysogobio microstomus, Saurogobio dumerili, Squalidus nitens, Acheilognathus gracilis, Sarcocheilichthys kiangsiensis, Sarcocheilichthys parvus, Rhodeus fangi, Micropercops swinhonis, Repomucenus olidus.
