Abstract. Distribution of macroinvertebrate functional feeding groups in running waters is believed to reflect process-level aquatic ecosystem attributes, so they can potentially be used in assessing aquatic ecosystem health. In the present study, the composition and abundance of functional feeding groups of the benthic macroinvertebrate communities of Barna sub-basin were studied. Benthic samples were collected from six streams. During the survey, five major macroinvertebrate functional feeding groups were recognized which include; gathering-collectors, filtering-collectors, predators, shredders and scrapers. In terms of relative abundance, scrapers and gathering-filterers were the predominant functional feeding groups in the Barna subbasin of Narmada River basin. They contributed 61% and 18% respectively to the total benthic macroinvertebrate population. Moreover, a significant variation in the composition of the various functional feeding groups in different stations was also observed. Most functional feeding groups were represented down the whole length of the study stretch which was found primarily associated with the land use patterns within the catchment area of Barna sub-basin in the present study. The implications of the observed pattern of functional feeding groups in Barna sub-basin, for ecological integrity assessment and ecosystem functions were also studied.

The present study was aimed to assess the diversity, distribution and abundance of macrozoobenthos in Parbati River (Madhya Pradesh). During the present investigation, 5 sampling stations were selected to collect the samples. Shannon diversity index and Margalef's richness index was used on benthic data obtained during the survey. A total of 50 taxa of macrobenthic fauna were recorded from different sampling stations of Parbati River. The phylum Arthropoda was found dominant followed by mollusca and annelida. The maximum diversity and richness were recorded during winter season while minimum diversity was recorded during monsoon. Among the EPT, Ephemeroptera were reported only at the reference site, while Plecoptera and Trichoptera were absent at all the stations.

The present study was conducted on the Kolar River, a tributary of the Narmada River. The fish diversity of the Kolar River in the Sehore district of Madhya Pradesh, Central India, is represented in this view. It was investigated from February 2021 to June 2022. The Kolar River is a vital source of water for the people who live in nearby villages, primarily for domestic use. In the community, fishing for a living and food is a common practise. The study's goal was to investigate the Kolar River's water quality and fish fauna. During the investigation, six sampling stations were chosen for the collection of data: Near reservoir, Lawakhadi, Veerpur, Near old bridge, Dana baba temple, Amdoh, and Jholiyapur. The study discovered 25 fish species from eight orders (Cypriniformes, Siluriformes, Perciformes, Osteoglossiformes, Synbranchiformes, Clupeiformes, and Beloniformes). Cypriniformes are the dominant order of fishes in this area (Kolar), with the highest number of ten species recorded. The recorded fishes were found to be widely distributed and abundant in the river.

Fisheries play an important role in supporting livelihoods and providing food for over one billion people around the world. The study aims to better understand fishermen's livelihood patterns in the Kolar River basin, a tributary of the Narmada River in Madhya Pradesh, India. The current study was conducted from September 2020 to June 2022 to assess the livelihood status of the traditional fishing community of the Kolar River adjacent to the Bhopal region. During the study period, data were collected from 14 villages as well as Veerpur,
