Length-weight relationships of 11 fish species from the Yibin reach of the Yangtze River, southwest China

Abstract

Length-weight relationships (LWRs) were evaluated for 11 fish species from the Yibin reach of the upper Yangtze River, southwest China. Samples were collected from April 2012 to January 2013. Length-weight relationships for 11 species were unknown to FishBase, and new maximum lengths are recorded for five species. Results indicate that parameter b ranged from 2.586 (Sinibotia superciliaris) to 3.164 (Rhinogobio ventralis), and r2 values ranged from 0.931 (Sinibotia superciliaris) to 0.996 (Silurus meridionalis).
