Summary From February to October 2016, a total of 9,754 fish specimens were collected from the Yiluo River, a tributary of the Yellow River, China's second longest river. Based on these samples, length–weight relationships ( LWR s) and length–length relationships ( LLR s) were estimated for 26 species. Among these data, LWR s for 1 species, LLR s for 11 species, and maximum total lengths for six species were not previously recorded in FishBase. The a values of the LWR s varied between 0.0019 and 0.0116, and b values from 2.805 to 3.883. All regressions for LWR s and LLR s were highly significant ( p < .001). These results will be useful for sustainable management and conservation of the fish resources in the Yiluo River and the Yellow River ecosystem.
