Threat Analysis: The study highlighted that earlier in 1879; these freshwater-loving mammals swam along the entire length of Ganga and Brahmaputra and all of their tributaries. From the delta of the Bay of Bengal up to the Himalayan foothills. Today at the merging of Ganga, Brahmaputra, and Meghna which form the Sundarban region, these dolphins struggle to survive. India’s “Dolphin Man” RavindraSinhahas observed that water diversion, commissioning of large barrages upstream have impacted the salinity profile of rivers downstream in central Sundarbans. The declining flow of the Ganga is the biggest threat to Gangetic dolphins along with water-intensive agriculture in the basin. Bihar constitutes 50% of mammals in the country. India’s only protected area for Gangetic dolphins is at VikramshilaGangetic Dolphin Sanctuary in Bihar. Asia’s First National Dolphin Research Centre is coming up in Patna to give a boost to the research and conservation of dolphins. Other Threats: Biological resource use: Fishing & harvesting aquatic resources, Natural system modifications: Dams & water management/use Pollution: Industrial & military effluents, Agricultural & forestry effluents. 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
