Abstract

The river of Krka boasts a large number of natural habitats with an extraordinary degree of biodiversity and a considerable number of endemic species. Another characteristic feature of the river is its barrage lakes, Brljan and Visovac lakes, which were created by virtue of travertine barriers. Considering their position, we can expect certain differences in the qualitative and quantitative composition of the macrozoobenthos communities and the ecological status. During one year we collected macrozoobenthos samples on two stations using grabbers (in the middle, in the deepest part of the lake and by the coast, at points where there is water vegetation) in three different locations. In the laboratory we isolated the representatives of the groups and performed determination to the lowest systematic categories. Given than the macrozoobenthos of the lakes has not been studied, the basic goals are to establish the seasonal and spatial differences in the qualitative and quantitative composition of the communities and establish the ecological status of the lakes through their analysis and monitoring the appropriate physical and chemical indicators.
