India First River Dolphin Census

India’s First River Dolphin Census: Key Findings & Conservation Roadmap

Introduction

India has completed its first-ever large-scale survey of riverine dolphins, revealing a total count of 6,327 dolphins across the Ganga, Brahmaputra, and Indus river systems. This initiative, undertaken as part of Project Dolphin, provides crucial insights into the conservation status of these endangered freshwater mammals. The survey results, published in a government report, underscore both the ecological significance of these dolphins and the urgent conservation measures needed to protect them.

Understanding Riverine Dolphins in India

1. Ganges River Dolphin: India’s Blind Swimmer

The Ganges river dolphin (Platanista gangetica gangetica) is an endangered species native to the Ganga-Brahmaputra-Meghna river system. Known for their near-complete blindness, these dolphins rely on echolocation for navigation and hunting. Because of their sensitivity to water pollution and habitat changes, they are key indicators of river health.

2. Indus River Dolphin: A Species on the Edge

A close relative, the Indus river dolphin (Platanista gangetica minor), primarily inhabits the Indus river system in Pakistan, but a tiny population—just three individuals—was recorded in India’s Beas River, Punjab. This alarming statistic highlights the critical conservation urgency for the species.

Project Dolphin: India’s Conservation Initiative

1. The Vision Behind Project Dolphin

Launched in 2020 by Prime Minister Narendra Modi, Project Dolphin aims to:

✅ Improve scientific monitoring of dolphin populations

✅ Restore natural habitats by mitigating pollution

✅ Reduce human-induced threats, including accidental net entanglements

2. The Nationwide Dolphin Census

Between 2021-2023, India conducted its first large-scale river dolphin survey, covering over 8,000 km of river channels across eight states:

📌 Uttar Pradesh, Bihar, Jharkhand, Rajasthan, Madhya Pradesh, West Bengal, Assam, and Punjab.

This marks one of India’s most extensive freshwater biodiversity assessments.

Findings of the River Dolphin Survey

1. Total Population Estimates

The government report, Population Status of River Dolphin in India, reveals:

🟢 Total Ganges River Dolphins: 6,327 (range: 5,977 – 6,688)

🟢 Total Indus River Dolphins: 3 (all in Punjab’s Beas River)

2. State-wise Distribution of Dolphins

🔹 Uttar Pradesh and Bihar have the highest populations, while the Indus dolphins in Punjab remain on the brink of local extinction.

3. Survey Methodology

The research combined:
Boat Surveys – Direct dolphin observation using surface sightings & tracking

Road Surveys – Analysis of historical habitats and local reports

These methods ensured a comprehensive and standardized dolphin population assessment.

Conservation Significance & Challenges

1. Why River Dolphins Matter

As indicator species, river dolphins reflect the health of freshwater ecosystems. Protecting them helps preserve entire aquatic food chains, benefiting biodiversity, local fishing communities, and water quality.

2. Major Threats to Their Survival

Pollution – Industrial discharge & agricultural runoff degrade habitats
Habitat Destruction – Dams, sand mining, and water diversion reduce viable dolphin zones
Accidental Deaths – Fishing nets pose a major entanglement risk

Although river dolphins are protected under India’s Wildlife Protection Act (1972), illegal hunting and habitat loss persist.

Future Conservation Efforts

1. Strengthening Project Dolphin

Establish Dolphin Conservation Reserves
Increase local community participation in habitat protection
Enhance anti-poaching enforcement

2. Sustainable River Management

Maintain natural water flow to support dolphin breeding
Reduce plastic waste and industrial pollution in river systems
Strengthen fisheries management to minimize bycatch fatalities

3. Raising Public Awareness

Educational campaigns on dolphin conservation & river ecosystem health
Eco-tourism initiatives promoting dolphin-watching programs

FAQs

1. Why is this survey important for dolphin conservation?

This is India’s first large-scale dolphin population survey, providing scientific data for targeted conservation strategies.

2. What is India’s largest river dolphin species?

The Ganges river dolphin is the most abundant, with over 6,300 individuals recorded.

3. How do river dolphins help ecosystems?

They are apex predators, keeping fish populations balanced and serving as water quality indicators.

4. What are the biggest threats to river dolphins?

Habitat loss due to pollution, infrastructure projects, and illegal fishing practices.

5. How can the public help conserve river dolphins?

Reduce plastic waste
Support eco-friendly tourism
Participate in awareness programs

Conclusion

India’s first-ever river dolphin census marks a major step in conservation. With 6,327 Ganges dolphins and only 3 Indus dolphins, the survey highlights both hope and urgency in dolphin conservation efforts.

To secure the future of India’s river dolphins, immediate action is needed—through Project Dolphin, habitat protection, and public awareness. Their survival is linked to the health of India’s rivers, impacting millions who depend on these waterways for livelihood and sustenance.
