Based on the growth information for Protosalanx hyalocranius transplanting in Daoguanhe Reservoir, Hubei Province,the growth index,the growth rate and the other indexes were calculated. The regrssion relationship of the body length and the body weight were gained： W=1. 2120X10^-6L^3.1820 and Von Bertalaffy growth equation： L_t = 193. 03[ 1-e^{-0.3050(1-3328)}] W_t = 22. 72[l-e^{-0.3050(l-0.3328)}]³. This paper stated in detail the growth character of Protosalanx hyalocranius transplanted in Daoguanhe Reservoir, divided the growth into four stages and compared it with those in other reservoirs.It was concluded that Protosalanx hyalocranius had both biological effect and production benefit as well in the waters of Hubei Province.
