We have previously reported that the practice using rock shells is useful for environmental education. In this practice, the precise distinction of the sex of rock shells is very important. However, our preceding study demonstrated that there are many rock shells that are difficult to determine the sex. The purpose of the present
study was to obtain information about a suitable period for collection of female rock shells inhabiting in Kumamoto harbor, by examining the maturity of their ovary. As a result, the maturity of the ovary in female
rock shells was observed during periods from beginning of June to the end of August. In addition, since imposex in female rock shells inhabiting in the Kumamoto coastal waters was not found, it is likely that the
contamination of organotin compounds is improved.
