The most extended and deepest belt of macrophytic vegetation, the belt which almost without exceptions define the lower limit of littoral region of Lake Ohrid, consists algae from the family Characeae. Permanent presence of sunlight, well oxygen saturation, their density which decreases the waves action, together with the facts that these algae are food and shelter for the numerous endemorelic species from the very rich fauna of macro invertebrates, make the stonworts the most attractive life habitat in Lake Ohrid. Our results are found on researching of three types facies from four different localities in Lake Ohrid: sandy-muddy facies without of stoneworts, facies covered by stoneworts and facies covered by Gastropod and Bivalvia shells, also without of stoneworts. Without exceptions, in all four localities we approved the mentioned affirmation about the great importance of the stoneworms as life habitats, both by the number of present taxa and the density of the macro invertebrate communities.

The aim of this work is to present preliminary results of the Sava River investigation at five sites within the reach from Martinska Ves (Croatia) to Šabac (Serbia). A total of 70 macroinvertebrate taxa from 13 groups were recorded, with domination of molluscs and oligochaetes. Among them 7 alien species were registered. Invasive clam Corbicula fluminea was recorded at all five sites, while invasive amphipod Dikerogammarus haemobaphes was not recorded only at locality Šabac. It is expected that the taxa list of aquatic macroinvertebrates within investigated reach will contain more species, after the identification of the rest of biological material and more detail identification of certain taxonomic groups.
