About Ganges River Dolphin

• The Ganges River Dolphin, declared as India’s National Aquatic Animal in 2009, is an endangered freshwater dolphin species primarily found in the Ganges, Brahmaputra, and Meghna river systems.
• Known locally as Susu, it serves as an indicator of the health of river ecosystems due to its apex predator role.
• Key Features:
  • Scientific Name: Platanista gangetica gangetica
  • Physical Characteristics: Nearly blind, it uses echolocation to navigate and hunt.
  • Habitat: Prefers slow-moving waters with adequate depth and prey availability.
  • Diet: Carnivorous, feeding primarily on fish and invertebrates.
• Geographical Distribution:
  • Found in the Ganga, Brahmaputra-Meghna, and Karnaphuli-Sangu river systems in India, Nepal, and Bangladesh.
  • Historically widespread, but populations are now fragmented due to anthropogenic pressures.
• Ecological Significance:
  • Keystone Species: Plays a crucial role in maintaining riverine ecosystem balance.
  • Indicator Species: Reflects the overall health of freshwater ecosystems.
• Conservation Status:
  • IUCN Status: Endangered
  • CITES: Appendix I
  • Indian Wildlife Protection Act, 1972: Schedule I
• Major Threats:
  • Habitat Degradation:
    • Pollution from industries, agriculture, and urban runoff.
    • Dams and barrages fragment habitats, reducing population connectivity.
  • Bycatch and Hunting:
    • Accidental entanglement in fishing nets.
    • Targeted for oil and meat in some areas.
  • Water Abstraction:
    • Excessive withdrawal of water for agriculture and industry impacts river flow.
  • Riverbed Alteration:
    • Sand mining and dredging disrupt habitats.

Conservation Efforts by the Government

• Project Dolphin (2020):
  • Announced by Prime Minister Narendra Modi, focusing on the conservation of both river and marine dolphins.
• Protected Areas:
  • Designated dolphin sanctuaries like Vikramshila Gangetic Dolphin Sanctuary in Bihar.
• Community Awareness:
  • Initiatives to educate local communities about sustainable fishing and conservation.
• Technological Interventions:
  • Satellite tagging projects for studying migration and habitat needs.
• Legislative Measures:
  • Strict enforcement of the Wildlife Protection Act and bans on harmful practices like sand mining.

News Summary

• India marked a significant milestone in wildlife conservation with the first-ever satellite tagging of a Ganges River Dolphin in Assam.
• This initiative, spearheaded by the Ministry of Environment, Forest and Climate Change (MoEFCC), was executed by the Wildlife Institute of India (WII).
• The project is part of the larger Project Dolphin.
• Objectives and Significance:
  • Understanding Habitat Needs: The tagging aims to fill knowledge gaps regarding the Ganges River Dolphin’s habitat requirements, migratory patterns, and range distribution.
  • Conservation Efforts: By studying their behaviour and movement, the project seeks to develop a conservation action plan for protecting this apex predator, which plays a vital role in maintaining the health of river ecosystems.
  • Technological Advancement: Lightweight satellite tags compatible with Argos systems were used, ensuring minimal interference with the dolphins’ movement.
• Broader Implications:
  • The project underscores India’s commitment to wildlife conservation and sets a benchmark for protecting endangered species globally.
  • It also highlights the need for continued technological advancements and comprehensive research to ensure the sustainability of river ecosystems.
  • This landmark effort reflects the growing awareness and proactive measures toward conserving India’s rich aquatic biodiversity.

Q1. What is the definition of an Ecotone?

Ecotone, a transitional area of vegetation between two different plant communities, such as forest and grassland. It has some of the characteristics of each bordering biological community and often contains species not found in the overlapping communities.

Q2. What is the main mission of IUCN?

IUCN works to develop best practices and approaches that enable effective conservation and help sites achieve high standards, while also informing professional capacity development and influencing national and global policy. IUCN is at the forefront of the global fight to save species from extinction.
