Morphological differentiation in the Indian major carp, Labeo catla, Ganga and Narmada rivers was studied using image-based morphometric multivariate analytical techniques. Twenty-three truss-network-based distances connecting 11 anatomical landmarks on fish were measured from digital images of specimens collected seven stations, four which set up along river Ganga, other three stations Narmada...

The present work focused to explore reproductive biology of fish from different Indian major rivers and its tributaries by comparing ovarian protein, fecundity, oocyte weight, oocyte diameter and condition factor during the spawning period. Correlation between fish reproductive parameter of different Indian major rivers and its tributaries showed a significant relationship. Among studied parame...

The present work focused on exploring reproductive biology of fish from different major rivers of India and their tributaries by comparing ovarian protein, fecundity, oocyte weight, oocyte diameter and condition factor during the spawning period. Significant correlation was found between reproductive parameters of fish in the major rivers and their tributaries. Among the parameters studied fecu...

The aim of this study was to assess the environmental impact of socio-cultural practices on the water quality of River Ganga at the foothills of the Garhwal Himalayas in Uttarakhand State, India. The physico-chemical parameters that contributed to the temporal variation and pollution in the river were identified in this study. Principal component analysis (PCA) and Cluster analysis (CA) were us...

Present study is carried out for the removal of As(lII) from water using commonly available adsorbents such as sand, from Yamuna river (Delhi ), as well as from Ganga river (Kolkata), activated carbon, Hametite ore and sand -iron scrap mixture. All these adsorbents are used as received but sand and activated carbon which do not show much adsorption for As(lII) are modified by treating with diff...

Length-frequency distribution, morphometry, length-weight relationship, relative condition factor and sex ratio of the apple snail Pila globosa (Swainson, 1822) were studied from river Ganga. A total 922 specimens collected during July 2020 to June 2021, ranging 3.53 62.99 g 16.49 59.78 mm (shell length). distribution revealed that more than 50% male female within 35 45 in length only few (1.58...

We demonstrate a novel mobile application called GangaWatch that makes water pollution data usable and accessible focusing on one of the most polluted river basins in the world. It is intended to engage common public who want to see water condition and safe limits, and their relevance based on different purposes. The data is a combination of old data determined from lab tests on physical sample...

A diurnal study was undertaken in April 2014 to record the bacterial density and some of the physicochemical factors of the river Ganga near Ichapore, West Bengal, India. The pollution indicating bacteria (total coliform, faecal coliform and faecal streptococci) were found in maximum numbers at 14.00 hrs and minimum at 20.00 hrs. All the bacterial populations were abundant and showed diel rhyth...

In this paper we employ a stated preference environmental valuation technique, namely the choice experiment method, to estimate local public's willingness to pay (WTP) for improvements in the capacity and technology of a sewage treatment plant (STP) in Chandernagore municipality, located on the banks of the River Ganga in India. A pilot choice experiment study is administered to 150 randomly se...
