On the basis of determination of individual age of molluscs of genus of Viviparus after the number of marks of wintering on their lid the set descriptions of their linear growth in the different districts of Central Polesye. After correlation of coefficients of equalization of growth of Bertalanfi L∞ and k, by the indexes of growth of φ’ and Ò20, and also after character of correlation of these parameters with the indexes of environment (content of organic matter, ðÍ) found out differences between populations of Viviparus.
