Sea turtle species including leatherback turtles, green turtles, loggerhead turtles, hawksbill turtles, olive ridley turtles, Kemp's olive ridley turtles and flatback turtle distribute subtropical areas and tropical areas in the world and migrate from feeding ground to nesting ground. The number of their population decreases and all these species face extinction in the world including the Southeast Asia. There are many reasons to decrease the number of the sea turtles. The global climate change caused the change of marine environment and affected the sea turtle. Otherwise, artificial reasons such as a coastal development and fishing activity are also serious matters now. Based on the result the former project, "Analytical study on the mechanism of wild migration of green turtles in the ASEAS sea areas" (KAKENHI, 2002 - 2004), this study performed some experiments to clarify a mechanism of migration of juvenile and young sea turtles and to compare the swimming ability between wild hatchery juveniles and artificial ones. Judging from the results, it is indicated that the hatchling juveniles have good ability to swim off but the ability is lost with their growth. Moreover, there may be difference in the diving behavior between the wild young sea turtles and the artificial rearing ones.

海龟物种，包括棱皮海龟，绿海龟，木龟海龟，霍克斯比尔海龟，橄榄雷德利海龟，肯普的橄榄雷德利海龟和扁平乌龟分布世界上的亚热带地区和热带地区，并从喂食地迁移到巢穴。他们的人口数量减少，所有这些物种在包括东南亚在内的世界上灭绝。有很多理由减少海龟的数量。全球气候变化导致了海洋环境的变化，并影响了海龟。否则，现在的人工原因（例如沿海发展和捕鱼活动）现在也很严重。根据前一个项目的结果，“对海洋地区绿海龟野生迁移机制的分析研究”（Kakenhi，2002年，2004年），这项研究进行了一些实验，以阐明少年和幼年海龟迁移的机制，并比较野生孵化能力与野生孵化能力之间的游泳能力。从结果来看，可以表明孵化少年有良好的游泳能力，但能力随着其增长而失去。此外，野生的幼年海龟与人造饲养的行为之间的潜水行为可能有所不同。
