这项研究的目的是估计杂种大比目鱼幼虫的定居日期，并猜测它们如何定居在日本海玄界滩育苗地底部的机制。根据生长曲线长度模式的变化，在定居后的生长期间（5 月至 9 月）识别了 4 个大小组的杂种大比目鱼。通过将 BERTALANFFY 的增长方程应用于当前数据，他们的定居日期估计为 4 月 9 日和 24 日以及 5 月 7 日和 22 日。他们定居的这四个日期得到了对定居的大比目鱼幼鱼的实地调查的证实，并且几乎与该时期的四次大潮一致。
This study was carried out to estimate the dates of settlement of larvae of the bastard halibut and to guess the mechanism how they settles on the bottom of their nursery ground in the Genkai-Nada, the Japan Sea. Four size-groups of the bastard halibut were recognized during the growing period (May to September) after their settlement, based on the shift of modes of the length in their growth curves. The dates of their settlement were estimated to be 9th and 24th of April and 7th and 22nd of May by appling BERTALANFFY'S growth equation to the present data. These four dates of their settlement were endorsed by field surveys of settled youngs of the bastard halibut, and almost coincide with the four spring tides during the period.
