| 内容記述 | The author investigated physical environments like as flow, bottom change, and underground temperature, etc. on the fishing ground of Venerupis philippinarum. As a result, the space and the temperature have understood as severe factors for clam larva as follows. The fluctuation of the bottom caused by the current was recorded 1cm or less/hr, and that caused by the wave at typhoon was recorded 3cm of less/hr. Because the living layer of the depositing larva repeats the scouring and sedimentation by the tidal current, it will be appropriate to assume a fixed larva to be moved with the sand. The fluctuation velocity of the bottom is slower than the burrowing speed of adult clam. Therefore, whether the clam takes the burrowing action is a turning point of her survival of death caused by exposing or burying. The soil temperature in exposed tidal flat rises rapidly in the summer sunny daytime, and the surface exceeds 37˚C. At this time, though the adult shell-fish will be able to evade the high temperature by deeply diving, it is assumed that the clam larva which live in a shallow layer is caused physiological disorder and dies. | |||||||||||
