| 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(R2=0.8419,P<0.01),F=8588.4L+24969(R2=0.9217,P<0.01),F=315.33W-9688.8(R2=0.9631,P<0.01)。

| Abstract: | 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(P<0.01) were as follow: F=67054A+61567(R2=0.8419),F=8588.4L+24969(R2=0.9217),F=315.33W-9688.8(R2=0.9631). |
