Abstract
Results of a malacological survey of the Korana River are presented. The molluscan assemblages of this karstic river between its outflow from Plitvice Lakes and the inflow to the Kupa River at Karlovac were studied from 2009 to 2012. Altogether 33 aquatic molluscs (21 gastropods, 12 bivalves) were found at 13 sites. Theodoxus danubialis, Esperiana esperi, Microcolpia daudebartii, Holandriana holandrii and Bithynia tentaculata were dominant at most of the sites. A population of the endangered thick-shelled river mussel Unio crassus was recorded. The occurrence of three non-native molluscs (Physella acuta, Ferrissia fragilis, Sinanodonta woodiana) was documented. The results of this research were compared with those of previous investigations and also with those for molluscan assemblages of the adjacent part of the Kupa River.
