Nationwide Dolphin Survey Launched in India
17 Jan
Summary
- Second nationwide survey for river and estuarine dolphins has begun.
- Previous survey estimated 6,327 riverine dolphins across India.
- Survey assesses habitat, threats, and pollution affecting dolphin populations.
The Union ministry of environment, forest and climate change has initiated the second nationwide range-wide survey of riverine and estuarine dolphins. Kicking off from Bijnor, Uttar Pradesh, this comprehensive exercise under Project Dolphin seeks to accurately assess dolphin populations and their habitats across India. The Wildlife Institute of India is coordinating the program with state forest departments and conservation groups.
The first survey round, concluded in March 2025, estimated 6,327 riverine dolphins, with Uttar Pradesh and Bihar showing the highest numbers. This ongoing survey will delve deeper into population distribution, habitat health, and critical threats such as fishing practices and water level fluctuations. Pollution data collection is also a key component.
Researchers will document ecological parameters and use technologies like hydrophones for underwater monitoring. The survey covers major rivers, including the Ganga and Indus, and will assess the status of Ganges River Dolphins, Indus River Dolphins, and Irrawaddy Dolphins, informing vital conservation policies.
