Abstract：The movement and growth of released F.chinensis into Laizhou Bay were investigated through several tracking surveys.The results showed that released F.chinensis populations moved out from Wei River to shallow coastal waters after getting a bigger body,and fuether to deeper waters until they finally left Laizhou Bay.Body-length frequency distribution of different sampling batches was almost unimodal.The relationship of body-length (L) and body-weight (W) could be expressed as W=8.0× 10-6L3.0611.Body-length and body-weight von Bertalanffy function were Lt =201.57 [1e-0.016(t-38.48)] and Wt=90.61× [1e-0.016(t-3848)]3.0611,respectively.The growth rate equations on body-length and body-weight were dLt/dt=3.23 × e-0.016(t-38.48) and dWt/dt =4.44 × e-0.016(t-38.48) × [1e-0.016(t-38.48)]2.0611,respectiveky.Besides,the growth inflection point occurred when the shrimp was 108 days old on August 15.
