Length-weight and length-length relationships of thirteen fish species from the lower Jinsha River, southwest China

Abstract

Length-weight and length-length relationships were investigated for 13 freshwater fish species from the lower Jinsha River, southwest China (from 101°32′49.63″E; 26°35′38.27″N to 104°37′48.14″E; 28°45′59.55″N). Fish were sampled from five sites during 2014 and 2016, using trap-nets, gillnets (major mesh size: 2–6 cm), longline and electrofishing. Length-weight relationships for six and length-length relationships for 12 species are the first report to FishBase, respectively. Moreover, new maximum length for 11 species are also presented to FishBase in this study. All regressions were highly significant (p < .001), with the coefficient of determination r2 > .950. These information will be helpful for management and conservation in local fishes and fisheries.
