In this study the following contents referred the life history have be conducted for the two halfbeak fish, Hyporhamphus sayori and H. intermedius: distribution in Japan, the differential morphology, observation of developmental stages of egg, relations between water temperature and salinity, and hatched hour of egg and growth of larvae, morphological changes of larvae with the development, food habits, system of migration, daily growth, relation between the age and growth and others. These research and experiments have practiced mainly during field works, but the unable items in the wild were clarified by the experiments in laboratory with the reared fish. During these works the life history of the two halfbeak fish distributed in north waters from Kyushu have elucidated and the method of the preservation for Hyporhamphus intermedius, threatened species in Fukuoka were proposed, that is , the maintenance and the preparation of the WANDO, back water area equipped the biotope in the tidal area of river.

在这项研究中，以下内容是针对两种半嘴鱼，hyporhamphus sayori和H. Intermedius进行的生命历史：日本的分布，差异形态，对鸡蛋的发展阶段的观察，水温与盐度之间的关系的观察，以及幼虫的孵化小时和幼体的孵化时间，幼虫的成长与发展的形态变化，而幼虫的形态变化，而迁移，食物，食物，食物，食物，食物与系统之间的迁移，以及在幼虫之间，食物与幼虫的迁移，食物与系统之间的迁移，与幼虫的发展，食物和幼虫相关，又与幼虫的形态变化。这些研究和实验主要是在野外工作期间进行的，但是野外的无法使用的物品是通过饲养鱼实验的实验来阐明的。在这些作品中，提出了福库卡（Fukuoka）威胁性物种的Hyporhamphus Intermedius保存方法的两种半膨胀鱼的生活历史，也就是说，在河畔河畔的生物区域中，提议维护和准备。
