摘　　要：2012年6月-11月，对2012年4月在南四湖增殖放流的鲢、鳙生长状况进行了连续5次跟踪调查。结果表明：鲢体质量变化在50-400g范围内，为1-2龄；鳙体质量集中在50-350g，为1-2龄；增殖鲢生长（L，体长；W，体质量）与捕捞时间的关系方程为：L=12.633＋2.3391M＋0.0648M2，W=-89654＋61.933M＋2.3341M^2；鳙L=13.186＋1.004M＋0.2449M2，W=99.204-33.203M＋12.141M2。捕获南四湖鲢、鳙个体远未达到渐进体质量乃至拐点体质量，尚处于快速生长期，在增殖放流与捕获中应加强科学规范与管理。Growth in silver carp and bighead carp released into Lake Nansi on April of 2012 were observed at Luqiao, Dushandao and Jiangjihe of Lake Nansi from June to November in 2012 nearly monthly. The silver carp was ranged from 50 g to 400 g in body weight and from 1 to 2 years in age, and the bighead carp was varied from 50 g to 350 g in body weight and from 1 to 2 years in age. The growth equation of body length （L） and body weight （W） at various periods （month） after released was expressed as L-12.633＋ 2.3391M＋0.0648M^2 and 1V=-89654＋61.933M＋2.3341M^2 for silver carp and L=13.186＋1.004M＋0.2449M^2, W=99.204-33.203M＋l 2.141M2 for bighead carp. The silver carp and bighead carp captured in Lake Nansi had significantly less than the asymptote weight or the growth inflexion point body weight, indicating that they are still in a rapid growth phase. Thus it is suggested that the populations and resources of the silver carp and bighead carp be protected and utilized in a reasonable way in future resource enhancement.
