The purpose of this study is to suggest the age determination method of Saxidomus purpuratus. Samples of S. purpuratus were collected in Jinhae Bay in 2017. The method of observing with a lighting device is efficient in terms of time and economy since no additional procedure is required. However, shells thick larger than 2.4 mm were hard to observe. In this case, there is a method of cutting and dyeing the shell or dissolving with hydrochloric acid. These two methods can confirm the ring relatively clearly, but when using hydrochloric acid, the risk of damaging the shell is high. Therefore, it seems effective to observe the ring of S. purpuratus using a light device.
