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+2.3341M2；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。

G row th in silvercarp and bighead carp released into Lake N ansion A prilof2012 w ere observed atLuqiao,D ushandao and JiangjiheofLakeNansifrom JunetoNovemberin2012nearlymonthly.Thesilvercarpwasrangedfrom 50gto400ginbodyweight and from 1 to 2 years in age, and the bighead carp w as varied from 50 g to 350 g in body w eight and from 1 to 2 years in age. T he grow th equation of body length(L)and body w eight(W )at various periods(m onth)after released w as expressed as L=12.633+2.3391M+0.0648M2 and W=-89654+61.933M+2.3341M2 forsilvercarp and L=13.186+1.004M+0.2449M2,W=99.204-33.203M+12.141M2 for bighead carp. T he silver carp and bighead carp captured in L ake N ansi had significantly less than the asym ptote w eight or the grow th inflexion pointbody w eight,indicating thatthey are stillin a rapid grow th phase.Thus itis suggested thatthe populations and resources of the silver carp and bighead carp be protected and utilized in a reasonable w ay in future resource enhancem ent.
