Abstract
Bio monitoring is a method of using living organisms to determine the environmental condition and clean freshwater is an important natural resource for human need. A study on macro invertebrate diversity and water quality parameters were conducted in Godawari River of Lalitpur, State Number 3 of Nepal. The Godavari Spring, found 500 metres from the Botanical Gardens' main gate, is also well worth a look. Sampling was conducted on July 2018 and five sampling stations (S-1, S-2, S-3, S-4 and S-5) were selected and the distance between stations was 75 metres. Three replicates for both water quality sample and benthic macro invertebrates were collected for each sampling station. Results indicated good water quality based on WQI and A total of 1 phylum, 2 classes, 6 order, 25 families, and 1558 individuals were successfully sampled and recorded. The presence of Hydropsychidae, Baetidae, and Chironomidae with a high abundance of the families shows the potential to be used as biological indicators of a clean ecosystem. The analysis showed that the average value of Shannon Diversity Index, H’ (0.28) indicates that the distribution of macro invertebrates was uniform between stations. The correlation test showed that the WQI has a strong relationship with the diversity indices involved.
