Abstract: The morphology of the shells of different large fresh water snails collected from Fanchan paddy fields in July and August at the heights of the rainy season was studied in order to identify the snails. The family Ampullariidae comprises all the 150 snail species. We found the majority of the snails attached to rice plants and manually collected them. Morphometric readings were taken using a digital vernier caliper. Their heights range from 13.1 to 66.8mm. Fadama has the highest average shell height (48.92 mm). Fanchan Right has the lowest average (33.11 mm) while Fanchan Left has 40.31 mm. Fadama recorded the highest values for shell height, shell width, spire height, aperture length, and aperture width. Fanchan obtained the lowest value for all these morphometric characters. The researcher plotted the bar chart using Power BI, displaying the average shell height and shell widths for the three snail collection locations. These results might reflect differences in environmental conditions, nutrition availability, or other factors that affect shell growth at the different locations. More research on these snails is needed for proper identification and control strategies.
