Length-weight and length-length relationships of five fish species from the Zigui section of the lower Three Gorges Reservoir, Hubei Province, China

Abstract

This paper provides the length-weight and length–length relationships for five fish species in the Zigui section of the lower Three Gorges Reservoir of the Yangtze River. Specimens were collected from December 2014 to January 2017, using various types of fishing gear and electroshock fishing techniques. Length-weight relationships (LWRs) for one fish species and Length–length relationships (LLRs) for five fish species are unknown to FishBase. New maximum total lengths for four species were also recorded for FishBase. Moreover, standard-length to total-length equations for converting size measurements for these five species are presented.
