Assam Chief Minister Himanta Biswa Sarma on Tuesday, 16 June 2026, shared a video of the Gangetic river dolphin — locally called Xihu — spotted in the waters of the Brahmaputra near the outskirts of Guwahati, attributing the increased sightings to sustained conservation efforts by the state government.

Context

In his post, CM Sarma noted that the Gangetic river dolphin, known colloquially as Xihu in Assam, 'is being spotted frequently in the waters of Brahmaputra and its tributaries due to the extensive conservation efforts we've undertaken.' The video, shared publicly, shows what appears to be a live sighting of the endangered species near Guwahati. The post is significant because dolphin presence is widely regarded as a reliable indicator of river health.

The Gangetic river dolphin was declared India's National Aquatic Animal in 2009, placing it alongside the tiger and elephant as a flagship species for national conservation policy. The species faces threats from habitat degradation, fishing net entanglement, sand mining, and river pollution across the Ganga and Brahmaputra basins.

Policy Backdrop

Project Dolphin, announced in the Union Budget 2020-21, extended the model of Project Tiger to river dolphins, covering both the Ganga and Brahmaputra systems. The programme focuses on habitat protection, population monitoring, and reducing human-wildlife conflict along major riverine corridors. Assam, as a key Brahmaputra basin state, is a central participant in this national framework.

India's broader river-rejuvenation policy has increasingly tied aquatic species recovery to pollution control and wetland preservation. State-level habitat management and population surveys by forest departments complement the central scheme, creating a layered conservation architecture that researchers say is beginning to yield measurable results in some stretches of the river.

Stakeholders and Impact

Riverine communities, including Assam's fishing families who share the Brahmaputra with the dolphin, are both stakeholders and, at times, unintentional threats to the species through net fishing. Conservation programmes have therefore included community outreach and livelihood-linked incentives to reduce bycatch. Wildlife researchers use dolphin population density as a proxy metric for overall river ecosystem health, making sighting frequency data valuable for policy evaluation.

For Guwahati — a rapidly urbanising city on the Brahmaputra's southern bank — dolphin sightings on the city's outskirts carry particular symbolic weight, suggesting that urban river stretches can sustain biodiversity when managed carefully. Such sightings also carry potential for eco-tourism, which state governments across northeast India have been keen to develop.

What's Next

The Assam Forest Department is expected to conduct its next statewide dolphin population census, which will provide a quantitative baseline to assess whether sighting frequency translates into actual population recovery. Conservationists will also watch for any new protected river stretches notified under Project Dolphin in the Brahmaputra basin. A formal population estimate would give policymakers firmer ground to expand or intensify current interventions, and could strengthen Assam's case for additional central funding under the national programme.
