Variability of the shell of the Lymnaea stagnalis (Gastropoda) inhabiting the Minusinsk channel of the Yenisei river (Southern Siberia)

A list of statistical indicators characterizing the variability of the gastropod Lymnaea stagnalis (Linnaeus, 1758) is given. They characterize the mollusks collected on June 21, 2017 in the channel of the river Yenisei, crossing the entire city of Minusinsk (Krasnoyarsk region). A total of 46 shells were examined. The measurements were performed according to five conchiological parameters. The size range of mollusks ranged from 19.65 to 45.53 mm. The results obtained are recommended for use in a comparative analysis of L. stagnalis from other water bodies, as well as for regular biological monitoring of regional water bodies.
