| 摘 要： | 根据灰色系统理论，建立了拟合鱼类生长的灰色动态生长模型，并应用这一模型和一般ＶＢＧＦ及特殊ＶＢＧＦ拟合了大伙房水库鲢鳙的体长生长和体重生长。这三个模型拟合鲢的体长生长的残差平方和分别产７．７７、８．５６、１８１５．９，拟合链的体重生长的残差平方和分别是０．０７、０．１５、５３．８８，拟合鳙的体长生长的残差平方和分别是２．４７、５．４９、２２９５．３，拟合鳙的体重生长的残差平方和分别为１．０５、０．

| Abstract: | A new model to fit growth of fish is established in the light of grey systemictheory. The formula of grey dynamic growth model (GDGM) is as follows:GDGM, specialized VBGF and generalized VBGF were used for fitting the body length andweight growth of silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthysnobilis ) in Dahuofang Reservoir. The sums of residual squares were compared with oneanother. Based on the results, GDGM is the best precise model to fit the growth and GDGMcan be used more extensively because of less hypothetic term than others. |
