Summary This paper provides the length–weight relationships of three fish species from the middle and lower reaches of the Jinsha River, China. Samples were obtained seasonally during 2013~2016 using fishing gear (drift gillnets and di long) and electroshock fishing techniques (backpack electrofishing control unit powered by 12 V). For each species, the sample size, length range, weight range, LWR, 95% confidence intervals of a and b , and coefficient of correlation were determined. Length–weight relationship (LWR) for one species was unknown to FishBase and new maximum lengths were recorded for two species.
