  • MOVEMENT LIMIT TACHOMETRY EXPERIMENT BETWEEN MUSSELS ON FIXED BED CHANNEL

抄録

<p>From the sampling and survey work in Azamenose area, we found that there are three kinds of fresh water mussels. It was believed that, these mussels was transfer or brought by floods into this area. However, this presumption content be proved as the water flow, water fluctuation was not measured. In order to clarify the assumption of this process we performed a movement limit tachometry experiment for these mussels. From this experiment, the result showed that the Anodonta sp. can be transfer by a slow current velocity. The same result also exhibit by two other mussels Unio douglasiae nipponensis and Lanceolaria grayana. In addition Anodonta sp. showed a significant correlation between shell length and movement velocity limits. As a conclusion, we conclude that, the main factor that control the movement velocity are the form of the mussel.</p>
