摘  要：
对江苏昆山市傀儡湖冬季围网捕捞到的鲢(Hypophthalmichthys molitrix)、鱅(Aristichthys mobilis)的生长状况进行了测量分析。结果表明:在保水渔业模式下,鲢、鳙的生长速度慢于传统放养模式;鲢的全长、体重生长方程分别为:Lt=73.12×[1-e-0.35(t+0.86)];Wt=7.74×[1-e-0.35(t+0.86)]2.9031,鳙的全长、体重生长方程分别为:Lt=94.35×[1-e-0.25(t+0.73)];Wt=15.26×[1-e-0.25(t+0.73)]2.7372;鲢体重生长速度以1-3龄较高,生长拐点为2.2龄,鳙体重生长速度以1-4龄较高,生长拐点为3.3龄。为了使鲢、鳙放养的除藻效应和经济效益达到最优,傀儡湖渔业利用鲢应以4龄为起捕年龄,鳙应以5龄为起捕年龄。

摘  要：
The growth performance of Hypophthalmichthys molitrix and Aristichthys mobilis in Lake Kuilei,Kunshan City,Jiangsu Province,was analyzed during winter seine fishing.The results showed that,the growth rates of these two fish species in the aquatic environmental protection oriented fishery were slower than that in traditional stocking mode.The growth equations of total length and weight for H.molitrix were Lt=73.12×[1-e-0.35(t+0.86)] and Wt=7.74×[1-e-0.35(t+0.86)]2.9031,respectively;and for A.mobilis were Lt=94.35×[1-e-0.25(t+0.73)] and Wt=15.26×[1-e-0.25(t+0.73)]2.7372,respectively.In Lake Kuilei,H.molitrix grew relative faster at the age 1 to 3 years,A.mobilis grew relative faster at the age 1 to 4 years;the growth inflecting point for H.molitrix and A.mobilis were 2.2 and 3.3,respectively.In order to obtain the best effect on algal bloom control and economic benefit,the best catching age was 4 years for H.molitrix and 5 years for A.mobilis.
