太湖大银鱼生长特性的研究
王玉芬, 蒋全文

摘要:
本文根据太湖大银鱼(Protosalanx hyalocranius Abbott)周年生物学实测资料,并应用Von Bertalanffy生长方程进行计算,对大银鱼在太湖的生长规律及特点进行分析探讨,结果表明:1.体全长与体重呈幂函数关系:W=3.981×10-6L2.9359;2.Von Bertalanffy生长方程的各项参数值为:L=219.86(mm),W=28.56(g),K=0.1469,t0=0.33;3.生长拐点年龄为7、8月龄。

Abstract:
According to the biological data of Protosalanx hyalocranius Abbott measured annully, this paper presents its growth properties, growth curves which are fit with Von Bertalanffy growth model and resources properties of the population.The following conclusion has been drawn: 1.Body length and body weight have relation to power function W=3.981·10-6·L2.9395,R=0.999。 2.The parameters of Von Bertalanffy growth formula are L=219.86(mm), K=0.1469,t0=0.33,W=28.56(g)。 3.Age of growth inflection point is 7.64 month-age, while body weight equals to one-third of asymptotic weight.4.Considering growth properties of the icefish only, it is better that fishing season begins in the month of inflection point of month-age.
