  • Ovarian cycle, marsupial development and molt cycle of Archaeomysis kokuboi were studied to understand these processes as a whole event. Based on morphological characters the marsupial development is divided into 3 stages, Embryonic stage (duration time of 4 days), Nauplioid stage (5 days) and Postnauplioid stage (4 days). Morphological description was ma de for the 3 stages, and each stage was examined in relation to the corresponding stages of ovarian cycle and molt cycle.

  • In crustacea the molting cycle is the most important physiological process affecting growth, behaviour, reproduction and population dynamics through their life span. Particularly molt cycle is closely related to reproductive cycle, and it is important to determine the successive stages of molt cycle to understand reproductive phenomena including ovarian cycle and the development of the embryos in the marsupium.
