摘  要：
本文根据2006-2008年淀山湖鲢鳙标记回捕数据以及刺网调查数据,研究了淀山湖鲢鳙的生长,根据鱼类体长推算公式分别推算出鲢鳙的生长指标;并计算出淀山湖鲢鳙的体长体重关系和肥满度。体长和体重关系分别为鲢:W=6×10-5L2.8371,(n=216,R2=0.8886);鳙:W=5×10-5L2.8609,(n=55,R2=0.9747)。鲢鳙夏季肥满度分别为鲢:K2006=0.001913±0.000142、K2007=0.002165±0.000218、K2008=0.002115±0.000306、K2009=0.001966±0.000112;鳙:K2006=0.002129±0.000239、K2007=0.002346±0.000262、K2008=0.002382±0.000247、K2009=0.002436±0.000282。与其他水域相比,淀山湖鲢和鳙生长速度较慢。

摘  要：
Based on data of mark-release-recapture and gillnet surveys of Silver Carp(Hypophthalmichthys molitrix) and Bighead Carp(Hypophthalmichthys molitrix) in Dianshan Lake during 2006~2008,growth of Silver Carp and Bighead Carp were studied.Based on back calculation formulae of fish body length,the growth indexes of Silver Carp and Bighead Carp were calculated;the relations between weight and body length of Silver Carp and Bighead Carp and fat degree of Silver Carp and Bighead Carp in Dianshan Lake were also calculated.The relations between weight and body length of Silver Carp is W=6×10-5L2.8371,(n=216,R2=0.8886).The relations between weight and body length of Bighead Carp is W=5×10-5L2.8609,(n=55,R2=0.9747).Fat degree of Silver Carp in summer is: K2006=0.001913±0.000142,K2007=0.002165±0.000218,K2008=0.002115±0.000306,K2009=0.001966±0.000112.Fat degrees of Bighead Carp in summer are K2006=0.002129±0.000239,K2007=0.002346±0.000262,K2008=0.002382±0.000247,K2009=0.002436±0.000282.Compared with other water areas,growth speed of Silver Carp and Bighead Carp in Dianshan Lake is slower.
