Age and growth analysis is essential to fisheries management. Indirect methods to calculate growth are widely used; however, length frequency data analysis in sea cucumbers is complicated by high data variability caused by body wall elasticity. Here we calculated Isostichopus badionotus parameters of the von Bertalanffy growth function. In order to address bias produced by body wall elasticity, we compared the performance of four measurements and one compound index that combines different biometric parameters: the square root of the length-width product (SLW). Results showed that variability in length data due to body wall elasticity was controlled by using body length (Le) from the SLW compound index. Growth in I. badionotus follows a negative allometric tendency. Slow or zero growth periods were observed during October and November, when weather conditions were adverse.
年龄和生长分析对于渔业管理至关重要。计算生长的间接方法被广泛使用；然而，海参的体长频率数据分析因体壁弹性导致的数据高度变异性而变得复杂。在这里，我们计算了巴氏拟刺参的冯·贝塔朗菲生长函数参数。为了解决体壁弹性产生的偏差，我们比较了四种测量方法和一个结合不同生物统计学参数的复合指数的性能：长宽乘积的平方根（SLW）。结果表明，使用SLW复合指数中的体长（Le）可以控制因体壁弹性导致的长度数据变异性。巴氏拟刺参的生长呈现负异速生长趋势。在10月和11月天气条件不利时观察到生长缓慢或零生长期。
