提出了一种改进版的von Bertalanffy生长函数（VBGF），其中正弦波修改了VBGF的标准版本，使鱼类能够在夏季快速生长和冬季或旱季零生长（长度）的可变时期之间顺利过渡。给出了拟合新模型的非线性程序的关键特征，并着重介绍了零增长周期的估计。给出了在Salmo salar和Trisopterus esmarkii上的应用实例。
A modified version of the von Bertalanffy growth function (VBGF) is proposed in which a sine wave modifies a standard version of the VBGF, enabling a smooth transition between rapid summer growth and a variable period of zero growth (in length) during winter or during the dry season for aestivating fishes. The key features of a nonlinear routine for fitting this new model are also presented, with emphasis on the estimation of the period of zero growth. Application examples, to Salmo salar and Trisopterus esmarkii, are presented.
