Abstract: In this study, the aim was to highlight the influence of the physico-chemical quality of the water of rice ponds and fish ponds in the city of Daloa on the distribution of molluscs. This study was carried out from July to September 2020 and concerned 04 rice ponds and 04 fish ponds. The aquatic molluscs were collected using à turbid net (1 m2 of sampled surface) and a Van Veen bucket (0.25 m2 of sediment per sample). Physico-chemical analysis revealed that the waters of the fish pond were more alkaline and oxygenated. In contrast, the rice ponds were more mineralized. The inventory of molluscs showed the presence of 26 species divided into 10 families and 5 orders. The latter were more diversified and abundant in rice ponds (25 species and 4,606 individuals) than in fish ponds (17 species and 582 individuals). The influence of the water physico-chemical quality on the distribution of molluscs indicated that Melanoides tuberculata and Aplexa marmorata abounded in both excellent and good quality of water.
