Altogether, 118 taxa of macrozoobenthos were determined in the section between localities Tasovice and Dyjákovice. The highest values of macrozoobenthos were found on the stony substrate with mean values of biomass and density corresponding to 25.4 g.m<sup>-2</sup> and 6 033 ind.m<sup>-2</sup>, respectively. Lower values were determined on the sandy substrates with 5.8 g.m<sup>-2</sup> and 5 857 ind.m<sup>-2</sup>, respectively. The index of saprobity on the locality Tasovice corresponded to betamesosaprobity (Si = 1.70), for the locality Dyjákovice the same index was (Si = 1.80).
