Viviparus fasciatus was found to occur in large quantities in the Konfederatka, an old branch of the Vistula, cut off from the river. Extensive variations took place during the course of the year in quantity, distribution, and age and space structure. Viviparus fasciatus chiefly inhabited the littoral zone in which they formed periodical, large and distinctly formed groups. These groups recurred yearly in the same places and exhibited a certain independence of environment factors. The numbers of Viviparus fasciatus in the vicinity of these groups, and in the deeper parts of the water were very small.
