Abstract: The theory and methods of Grey System were used to establish the Forecasting Model of GM ( 1,1 ) to predict C, ymnocypris przewalskii przewalskii production on the basis of fishery data of C, ymnocypris przewalski przewalskiifrom 1991 to 1998. The GM ( 1,1 ) prediction fishery yield model was established asχ^(0)(k+1)=4974.9670996e^-0.232119k The mean error of regression testing was 10.33%. The difference check of the prediction model: C =0. 248352,P = 1 and the model precision ranks the first class. The predicted yield of the model in 1999 was about 776.8 t, with a relative error of 3.73% to actual yield. The model was proved to be feasible and suitable in this paper.
