Abstract

The survey of aquatic non-marine molluscs of the largest island in the Adriatic Sea done in the years 2015-2017 confirmed the occurrence of 28 species (18 freshwater and 4 brackish gastropods, 6 bivalves) at 72 sites, while previous research done about 60 years before found out only 7 species. Results of this research were compared with aquatic molluscan assemblages of other Croatian islands and the number of recorded species is the highest known of the islands in the Adriatic Sea. The probable reason for this relatively high diversity is the existence of various habitats together with the facts that it is the largest island in the Adriatic Sea, and is also relatively close to the mainland.
