Historic Tagging of Ganges River Dolphin in Assam

Today, milestone has been achieved in wildlife conservation with the first-ever tagging of the Ganges River Dolphin (Platanista gangetica) in Assam. This initiative is part of Project Dolphin, spearheaded by the Ministry of Environment, Forest and Climate Change (MoEFCC) and executed by the Wildlife Institute of India (WII) in collaboration with the Assam Forest Department and Aaranyak. This pioneering effort marks the first instance of satellite tagging for this species globally.

Importance of Ganges River Dolphin

The Ganges River Dolphin is India’s National Aquatic Animal. It plays important role as an apex predator in its ecosystem. The species primarily inhabits the Ganga-Brahmaputra-Meghna and Karnaphuli river systems. Historically, it has faced a drastic decline in population due to habitat loss and pollution.

Tagging Initiative Details

The tagging took place in Assam, where a healthy male dolphin was tagged and released under careful veterinary supervision. This exercise aims to gather critical data on the dolphin’s seasonal and migratory patterns, habitat utilisation, and distribution in fragmented river systems. The lightweight tags used are designed to emit signals compatible with Argos satellite systems.

Project Dolphin Overview

Project Dolphin is a comprehensive initiative funded by the MoEFCC through the National CAMPA Authority. The project aims to fill existing knowledge gaps about the Ganges River Dolphin. It seeks to develop a conservation action plan based on scientific research.

Challenges in Conservation

Ganges River Dolphins are elusive and typically surface for only 5-30 seconds, making it difficult to study their behaviour and ecological needs. This lack of information hampers effective conservation strategies. The tagging initiative is expected to provide valuable vital information about their habitat requirements.

Future Plans and Significance

The success of this tagging effort will pave the way for similar initiatives in other states where Ganges River Dolphins are found. About their population dynamics and habitat needs is vital for sustaining both the dolphin population and the livelihoods of communities dependent on these river ecosystems.

Role of Technology in Conservation

Advancements in technology have facilitated this tagging process. The tags are lightweight and minimally invasive, allowing for effective monitoring without disrupting the dolphin’s natural behaviour. This technological integration represents step forward in wildlife conservation efforts.

Government and Community Involvement

The initiative has garnered support from various stakeholders, including the government and local communities. It puts stress on the importance of collaborative efforts in wildlife conservation. The involvement of local organisations like Aaranyak marks the need for grassroots participation in ecological preservation.

Importance of Evidence-Based Strategies

The data collected from the tagging initiative will contribute to evidence-based conservation strategies. This approach is essential for addressing the challenges faced by the Ganges River Dolphin and ensuring the sustainability of its habitat.
