Abstract: The body length（L），body weight（W）and stomach contentweremeasured in 1434 individuals of Chinese shrimp Fenneropenaeus chinensis collected in the area of Pikou Bay in North Yellow Sea by six vessels during investigation from June 2015 to October 2015 to evaluate the growth characteristics of Chinese shrimp.Results showed that the relationship between body length and body weight of the Chinese shrimp was described by a power function formula：W=8×10-6L3.0729in female and W=9×10-6L3.0573in male.The growth equations of the Chinese shrimp was expressed by Von Bertallanffy growth equation as Lt=230.09［1-e-0.0098（t-29.54）］，and Wt=144.87［1-e-0.0098（t-29.54）］3.0729in female；Lt=175.05［1-e-0.0151（t-34.73）］and Wt=65.98［1-e-0.0151（t-34.73）］3.0573in male. There was different growth rate between female and male in Pikou Bay，better in male than that in female at early life.The female shrimp had better growth than themale ones did about74 days after stocking，with infection points in body weight in male about109 days and 144 days in female.The growth index k seemed to be smaller in Pikou Bay compared with
