“…A study was done by Rana et al 2015 in Budhigandaki river Nepal applied the biotic index as well as WQI for assessing the water quality for drinking purposes. Sharifinia et al, 2016 studied Shahrood river employing both WQI as well as BI for evaluating the water quality and suggested using Biotic Index for evaluating stream health.…”

Benthic macroinvertebrates are an indispensable part of aquatic ecosystems. They are used repetitively for evaluation of aquatic health since the emergence of the industrial revolution. Several studies show that their presence and absence are an indicators of aquatic health. In our study at the Amrit Ganga river, four sampling stations (consisting of sampling points each) were selected for the collection of aquatic macroinvertebrates. A total of n= 465 individuals were collected during the sampling period in which Trichoptera and Diptera appeared as dominant orders. According to functional feeding groups, the presence of filters and scrapers was higher than that of detritivore, and the presence of predators was lowest. Based on the presence of sensitive orders,%EPT (Ephemeroptera, Plecoptera, and Trichoptera) was calculated, and the maximum value calculated was 74.5% in (site 2) and the minimum value was 21% in (site 4). We also quantified the Water Quality Index approach which is based on physicochemical properties of water and the minimum and maximum values of WQI (Water Quality Index) varies from 33.94 in Site 2 to 48.61 in Site 4, indicating "excellent" (WQI<50) water quality in all the sites. This study serves as a baseline data for water quality monitoring programs and management and also to quantify the macroinvertebrates assemblage.

“…A number of studies related to water quality using physico-chemical parameters and biological indicators particularly macro-invertebrates, have been carried out in Western (Suren, 1994;Sharma et al, 2005;Gurung et al, 2013), Central (Shrestha et al, 2008;Rana and Chhetri, 2015) and Eastern (Jha et al, 2015;Gurung et al 2016) parts of Nepal. However, such studies in the far western part of Nepal are scarce.…”

Water quality of the West Seti River, a tributary of the Karnali in West Nepal was assessed using macroinvertebrates as bioindicators. The main objective of the study was to assess the ecological water quality of the West Seti River and to generate a baseline data on macroinvertebrate assemblages. The sampling was conducted during December 2015 and a total of 11 sampling sites were selected from the West Seti River and its tributaries. Qualitative samples of macroinvertebrates were collected from different habitats. Selected physico-chemical parameters such as pH and temperature were estimated on-site. Dissolved oxygen (DO) was estimated by Winkler's method. The macroinvertebrate samples were enumerated and identified up to Family level following standard literature. Chi-square test was performed to see whether macroinvertebrate taxa varied significantly along the altitudinal gradient and between the West Seti River and its tributaries. An ecological assessment tool Nepalese Biotic Score/ Average Score Per Taxon (NEPBIOS/ASPT) was applied to assess the water quality of the sampling sites. The pH value ranged from 7.9 to 8.7 indicating the alkaline nature of the river. A total of 1666 individuals belonging to 34 Families and 7 Orders of macro-invertebrates were observed. The highest diversity of the macroinvertebrate taxa was observed at site T5 with nineteen Families whereas the lowest taxa diversity was observed at R3 with only five Families. The variation in macroinvertebrate assemblages between the sub-tropical and temperate zones; and the West Seti River and its tributaries were not significant. NEPBIOS/ASPT revealed a score of Water Quality Class of III-IV at Site R3 indicating that the site was polluted. This site was characterized by the abundance of red Chironomids which are considered as the indicators of organic pollution.
