摘　　要：探讨了荷沅鲤生长所需要的适宜钙磷总量及最适钙磷比。结论是：无论钙磷总量是否相同，钙磷比皆以1：2为最适宜；在钙磷比为1：2时，钙含量为839～1189mg％，磷含量为1678～2378mg％，钙磷总量为2517～3600mg％，荷沅鲤生长最好；在钙磷比中磷小于2时，钙磷含量高会减轻因钙磷不平衡对鱼生长所造成的危害；钙磷总量过多或过少、钙磷比不等于1：2时，都会抑制鱼的生长，降低饵料转化率。Studies were made on the optimum contents of calcium, phosphorus and the ratio of Ca to P for the culture of He-yuan carp. A conclusion was drawn from experiments that in the range of Ca 839 ~ 1189 mg%, P 1678 ~ 2378 mg% and the total contents of Ca and P(2517 ~3600 mg% ), the optimal Ca/P ratio for the growth of He-yuan Carp is 1 : 2. If P is less than 2 in the ratio of Ca to P, the contents of Ca and P is high to reduce the harm to the growth of the carp because of the disequilibrium of the Ca and P, but if the total amount of Ca and P is much higher or less, or the Ca/P is bigger and smaller, carp growth will be inhibited, the food conversion rate will be reduced and the feed coefficient will be increased.
