Using biological assemblages to assess the ecological status of streams and rivers has a long history in European countries (Furse et al., 2006); therefore, a wide spectrum of biotic indices (e. g., Saprobien Index (SI), family-level biotic index (FBI), and Biological Monitoring Working Party (BMWP)) have been developed to assess anthropogenic ecological impairment in freshwater ecosystems (Doledec and Statzner, 2010).
