Résumé :	We studied macrozoobenthos of right-hand tributaries of the Danube in Serbia from 1989 to 1996 with special attention to qualitative and quantitative composition, dominance, frequency, elements of alpha-biodiversity and the following environmental variables: altitude, bottom structure, water flow rate, profile dimensions, water temperature, oxygen concentration, acidity, BOD(5) and concentrations of nitrogen, phosphorus and toxic substances. Five categories of streams were isolated by cluster analysis. Frequent taxa (genera, families and subfamilies) were classified within these categories and a matrix of habitat quality was used to derive a biotic index for the investigated region. Because Serbia is central to the Balkan peninsula, it is proposed that this index be designated the BalkaN Biotic Index (BNBI).
