摘　　要：对锦鲤（Cyprinus carpiod）的成熟系数和个体生殖力进行了研究。结果显示：雌、雄锦鲤成熟系数变化规律基本一致,成熟系数在5月下旬达到最高值。2^＋-5^＋龄锦鲤个体绝对生殖力F与其年龄A、体长L、体重W呈直线相关,回归方程分别为：F=67054A＋61567（R^2=0.8419,P〈0.01）,F=8588.4L＋24969（R^2=0.9217,P〈0.01）,F=315.33W-9688.8（R2=0.9631,P〈0.01）。The gonadosomatic index and the individual facundity of Cyprinus carpiod were studied.The results showed：The change of gomadosomatic indices of the females was almost the same with the males,and the peaks of gomadosomatic indices all appeared in late May.The females of age 2^＋～5^＋ were studied in the individual fecundity.The individual absolute fecundity（F） was linearly and directly correlative to age（A）,body length（L） and body weight（W）.The equations（P0.01） were as follow： F=67054A＋61567（R2=0.8419）,F=8588.4L＋24969（R^2=0.9217）,F=315.33W-9688.8（R^2=0.9631）.
