摘要

In aquatic environments, macroinvertebrates are the most useful markers of environmental quality because of their steady lifetime, manageable size, and distinguishing traits that facilitate sorting and identification. A water body’s condition can be determined by observing how different species of benthic macroinvertebrates react to biotic and abiotic elements in the community structure. In both polluted and unpolluted flowing waterways, benthic macroinvertebrates exhibit significant geographical and temporal variability across almost all scales. These species’ existence or absence, numbers, morphologies, physiologies, or behaviors can change depending on whether the physical and chemical water quality parameters are outside of the acceptable range (Sharma et al. 2006, 2010; Agboola et al. 2019). A comprehensive multi-habitat sampling protocol was used to collect 374 benthic macroinvertebrate samples overall, and each sampling site recorded a wide range of characteristics describing the streams and their catchments. To determine the degree of a site’s deterioration, a vast variety of metrics will be examined separately and in combination for each type of stream. A stream stretch can be categorized using this multimeric evaluation approach into one of five ecological quality classes, ranging from 1 (good quality) to 5 (poor quality), and it frequently offers details on potential reasons for degradation.
