India’s first Dolphin observatory
- An observatory would soon be developed to allow visitors to see Gangetic dolphins in Vikramshila Gangetic Dolphin Sanctuary.
- People would be able to watch aquatic activities of Dolphins in the river from an observatory tower, to be built as a part of Sultanganj-Aguwani Ghat bridge in Bhagalpur, Bihar
The Observatory
- The four-storey observatory will be 40 feet high, with the bridge passing through its middle.
- The observatory building will be transparent, with glass from all sides to ensure people can watch the dolphins without disturbing them.
- The structural design of the observatory is such that it will promote eco-tourism. There would be no bad or adverse impact on the river’s ecology as the observatory is being constructed on a bridge over the Ganga
The Gangetic dolphin
- Ganga river dolphin – Platanista gangetica
- Indus river dolphin – Platanista gangetica minor
- The Ganges river dolphin is primarily found in the Ganga and Brahmaputra Rivers and their tributaries in India, Bangladesh, and Nepal
- The Indus river dolphin is now found only in the main channel of the Indus River in Pakistan and in the River Beasin Punjab in India.
- National Aquatic animal of India (2009)
- National Mammal of Pakistan (Indus Dolphin)
- Surface breathing
- Echolocation
- Gangetic dolphins Prefer water that is at least 5ft to 8ft deep, where there are enough fish for them to feed on.
- They live in a zone where there is little or no current, which helps them save energy.
- If they sense danger, they can dive into deeper waters.
- The dolphins swim from the no-current zone to the edges to hunt for fish and return.
Endangered
- The population of the endangered Gangetic river dolphins was found in nearly 1,000 km stretch of the Ganga and its two major tributaries, Gandak and Ghaghra.
- According to a survey in 2019, 1,548 Gangetic dolphins have been spotted in Ganga, Gandak, Kosi and Mahananda rivers
- Dolphin presence is a sign of a healthy river ecosystem.
Vikramsheela Gangetic Dolphin Sanctuary
- Vikramsheela Gangetic Dolphin Sanctuary has been developed in the basin of Ganga between Sultanganj and Kahalgao in Bhagalpur district
- According to the latest estimate, there were nearly 170 dolphins in the sanctuary.
- National Dolphin Research Centre (NDRC) to come up in Patna University premises.
- Gangetic river dolphins have been declared an endangered species by the International Union for Conservation of Nature (IUCN).
- Wildlife (Protection) Act, 1972: Schedule I
- CITES: Appendix I
Threats
- Killed without intention after being trapped in Nylon nets of fishermen.
- The mammals are killed by poachers for their flesh, fat and oil.
- Boats and Machines hamper their echolocation abilities.
- Lowered water levels – – Sandbars in river- due to irrigation water use
- Multiple dams – fragmented population and limited gene pools.
Other Initiatives
- First turtle conservation and rehabilitation centre of eastern India in Bhagalpur’s sundarvan areas.
- Garur Conservation and Rehabilitation centre has also been proposed in Bhagalpur’s Kandawa diara (riverside) areas to save the species of Garur vultures.
