Summary Length‐weight and length‐length relationships were estimated for four native fish species from the Yalong River and its tributaries, China. A total of 976 specimens were collected monthly using trap nets and electric fishing in May 2013 and July 2015 to February 2016. This study presents the first references on LWR s (length–weight relationships) and LLR s (length–length relationships) for three species ( Gymnocypris firmispinatus , Paracobitis variegatus and Euchiloglanis kishinouyei ). Moreover, maturation length, absolute fecundity and predominant food items for the four species were also described in the study.
