Migratory abilities of Bithynia inflata have been studied. The investigations have been carried out in the West-Siberian nidus of opisthorchiasis during four summer seasons since 1975. Mollusks were marked with isotopes 60Co and 110m Ag. It has been established that the mollusks do not migrate for long distances, prefer to lead a settled life and do not leave their constant biotopes even during spring floods. Migrations of mollusks within their biotopes take place, in general, along the shore line. After drying of water mollusks spend this unfavourable period in surface layers of the bottom mud or under the layer of vegetation litter-fall.
已对膨胀膀胱螺的迁移能力进行了研究。自1975年以来，在西西伯利亚后睾吸虫病疫源地进行了四个夏季的调查。用同位素60Co和110m Ag对软体动物进行标记。已确定软体动物不会远距离迁移，更喜欢定居生活，即使在春季洪水期间也不会离开其固定的生物群落生境。软体动物在其生物群落生境内的迁移通常沿着海岸线进行。水体干涸后，软体动物在底部泥浆的表层或植被落叶层下度过这一不利时期。
