The Loucké Rybníky ponds State Nature Reserve was established in 1954 and due to negative effects of mining activities it was abolished in 1979. This article presents results of malacological survey in the Loucké Rybníky ponds (Karviná-Louky, Czech Republic) conducted in 2006 and 2007. The samples were collected at seven locations which match with sites sampled in 1954 and 1978; the location of sites were detected based on original schematic maps showing their position. The research was focused on aquatic species, terrestrial mollusc were collected only marginally. In 2006 and 2007, 38 mollusc species were found (35 gastropods and 3 bivalves), which include 17 species of aquatic molluscs and 21 terrestrial. Based on comparison with the data collected in 1954 and 1978 we conclude that the total destruction of aquatic habitats was irreversible and lead to changes in the species composition. Several rare and endangered species have extinct at this site and the total species richness of aquatic species decided from 29 to 17.
