Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers. Water quality analysis is mainly done using physical and chemical attributes in the DR Congo. The objectives of this study were to assess the biological water of Cirhanyobowa River using macroinvertebrate index and the relationship between physicochemical parameters and the ecological index from January to December, 2017. Eight physicochemical parameters and abundance of macroinvertebrates were obtained for 6 sites from upstream to downstream part, with different land uses. Result showed a decrease in biotic index from upstream (very good water quality) to downstream (bad) due to human activities along the river flows. Brick mining in the downstream part had more effects than agriculture in the upstream part. A correlation analysis showed the variation between the ecological index, abundance of macroinvertebrates and their correlation with physicochemical parameters in Cirhanyobowa River. The findings show that traits can be indicative for different kind of stress but that more effort has to be put in gathering data sets to separate the effect of habitat quality, pollution, and the physicochemical properties of high mountain rivers.
