Abstract

This paper presents the results of a malacological survey of Pag Island, which is among the largest islands of the Croatian coast, and is situated in the northern Adriatic Sea. Altogether 13 species of aquatic non-marine molluscs (12 gastropods, 1 bivalve) were found at 39 sites in 2009–2011. Three recorded species, Hydrobia acuta, Myosotella myosotis, Ecrobia ventrosa, inhabit brackish waters while the other species are freshwater molluscs. The occurrence of Pseudamnicola conovula, a mollusc endemic in several Croatian islands, was confirmed. Kerkia kareli, a species described in 2014, which inhabits phreatic waters, was found at three sites. Results of this research were compared with previous investigations and also with aquatic molluscan assemblages of other Croatian islands.
