A method is presented for estimating rates of individual growth and population mortality utilizing average individual size at two times during a year. The model assumes a constant rate of mortality, Brody-Bertalanffy growth, a stationary age distribution, and recruitment confined to one month each year. A hypothetical example is presented to show the interrelationships of the growth and mortality constants, size at recruitment, asymptotic size and average individual size. Three examples are presented using data from the literature: Flathead sole (Hippoglossoides elassodon), a sea urchin(Echinus esculentus), and the crown-of-thorns starfish(Acanthaster planci). The method appears to be a means of obtaining reasonable approximations of growth and mortality rates for a variety of organisms.
本文提出了一种利用一年中两个时间点的个体平均大小来估计个体生长率和种群死亡率的方法。该模型假设死亡率恒定、符合布罗迪 - 贝塔朗菲生长模式、年龄分布稳定且每年的补充仅限于一个月。给出了一个假设示例以展示生长常数、死亡率常数、补充时的大小、渐近大小和个体平均大小之间的相互关系。使用文献中的数据给出了三个示例：太平洋扁头鲽（Hippoglossoides elassodon）、一种海胆（Echinus esculentus）和刺冠海星（Acanthaster planci）。该方法似乎是一种获得各种生物生长率和死亡率合理近似值的手段。
