The article provides data on the biotopic distribution of freshwater molluscs in different types of ponds of water basin of the middle and upper currents of the Chulym. Here is examined a biodiversity and a quantitative development of freshwater molluscs in different habitats and their role in macrozoobenthos in river waters of ponds and rivers, floodplain lakes. The greatest species diversity, the abundance and biomass of molluscs are in the silts in all types of water bodies and the complete absence of them in pebbles in the strong currents. Floodplain lakes are characterized by the greatest diversity of species and quantitative development 57 58 of the freshwater molluscs. The article provides a list of the species of freshwater molluscs of middle and upper currents of the basin of the river Chulym and the distribution of zoobenthos and shellfish productivity in different types of water bodies
