Socio-economic factors threatening the survival of Ganges River Dolphin Platanista gangetica gangetica in the upper Ganges River, India

Abstract

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.
