  • Title
    On the Behaviour, abundance, habitat use and potential threats of the Gangetic Dolphin Platanista gangetica in southern West Bengal, India
    Type
    Journal Article
    Description
    The Ganga River Dolphin Platanista gangetica Roxburgh, 1801 is a globally endangered cetacean found in the River system of Ganga, Brahmaputra and Meghna in Bangladesh and India. A survey and research were conducted from 2012–2014 to explore the behaviour, abundance, habitat use and potential threats of the Dolphin in the lower, middle and upper stretches of the river Ganga and its tributaries in southern West Bengal. The study recorded different types of surfacing patterns with respect to their age class as well as on diurnal activity pattern of the individual. The adults and sub-adults were found to have different types of surfacing during different hours of the day. The morning and afternoon were observed to be feeding hours of the Dolphin. Multiple potential threats were encountered during the present study such as destructive fishing gears, dumping of solid and municipal waste, industrial effluents, agricultural run-off, construction of water structures, water extraction and reduction of river depth attributed to siltation. These factors contributed to the present study of the river dolphins in the Ganga, which are localised at certain pockets in good number.

  • Title
    Socio-economic factors threatening the survival of Ganges River Dolphin Platanista gangetica gangetica in the upper Ganges River, India
    Type
    Journal Article
    Description
    The present study was conducted along the upper Ganges River between Narora barrages and Anupshahar from January to June 2007. Community interviews were conducted in order to assess the socio-economic profile of the fishermen community, their level of dependence on the river and their attitude towards the conservation of Ganges River Dolphin Platanista gangetica gangetica. The estimated literacy rate from interviews was 45%, and average annual income per household was 27,000 INR (Indian National Rupee). The respondents were found to be well aware of the river biodiversity and believed excessive water extraction and pollution to be the responsible for any perceived decline in the dolphin population. About 55% of the fishermen were found to fish for commercial purposes, and a majority of them (71%) used nylon gill-nets. A majority (94%) of respondents that had boats of their own fished in the middle of the river, an activity often conducted in groups. 12% of respondents reported to have encountered dolphin carcasses. Excessive fishing and dolphin poaching were found to be interrelated; if fishing can be more effectively managed poaching may automatically decline. 41% of the fishermen interviewed were found to be willing to stop fishing providing adequate alternative livelihoods are provided by the government.
