In order to clarify origin and formation of lunar-synchronized spawning activities in reef fish, annual reproductive cycle and spawning rhythm of fish inhabiting tropical coral reefs in Central Java, Indonesia were examined. Most studies were carried out using rabbitfish, because similar studies have been conducted in sub-tropical coral reefs in Okinawa, Japan. When the fish were monthly collected from coral reef or purchased from fishermen, most fish had definite reproductive seasons, which occurred around changing season from dry to wet or from wet to dry. During the reproductive season, the fish were collected weekly according to lunar periodicity in order to know spawning rhythm. As a result, rabbitfish species repeated a lunar-related spawnings during the reproductive season. For example, the golden rabbitfish, Siganus guttatus, developed the gonads toward and spawned around the first quarter moon. Comparison of lunar-related spawning activity between Central Java, Indonesia and Okinawa, Japan, revealed that the golden rabbitfish spawned around the same lunar phase (the first quarter moon). The present study suggest that the fish have annual reproductive season which is closely related to regional environments and that the same cues from the moon are used as Zeitgeber for synchronized spawning in any regions.

为了阐明月相同步产卵活动的起源和形成，对印度尼西亚中爪哇热带珊瑚礁鱼类的年繁殖周期和产卵节律进行了研究。大多数研究都是用兔鱼进行的，因为在日本冲绳的亚热带珊瑚礁上进行了类似的研究。当每月从珊瑚礁采集鱼或从渔民那里购买鱼时，大多数鱼有明确的繁殖季节，发生在从干到湿或从湿到干的季节变化。在繁殖季节，根据月相周期每周采集一次，了解产卵节律。因此，兔鱼在繁殖季节重复了与月球相关的产卵。例如，金兔鱼（Siganus guttatus）的性腺是在第一个月前后发育并产卵的。比较印度尼西亚中爪哇和日本冲绳与月球相关的产卵活动，发现金兔鱼在相同的月相（上弦月）产卵。目前的研究表明，该鱼类每年有一个繁殖季节，这与区域环境密切相关，并且来自月球的相同线索在任何地区都被用作同步产卵的授时虫。
