Teesta River Fish Deaths: The sudden appearance of large numbers of dead fish floating in the Teesta River near Domohoni in Jalpaiguri district has shocked residents, environmentalists, and government officials. Preliminary investigations by the state fisheries department suggest that toxic chemicals were deliberately poured into stagnant water, leading to mass fish mortality. This incident is not isolated—similar events have occurred in the past, raising urgent questions about river pollution, ecological balance, and governance failures.
Teesta River Fish Deaths: The Incident
On December 10, 2025, residents spotted thousands of dead fish near Mirichbari in Mainaguri block. Species such as rohu, boroli, aar, punti, foli, and shol were found lifeless. Officials collected water and fish samples for testing, with early reports indicating contamination by toxic oil or chemicals.

Human Cost
The tragedy has a direct impact on local communities:
- Fisherfolk lose livelihoods as river fish stocks collapse.
- Residents risk health hazards if poisoned fish are consumed.
- Daily wage workers who depend on fishing and small trade face economic insecurity.

Historical Context
Fish poisoning in the Teesta is not new:
- In 2011 and 2015, similar incidents occurred in the Karala River due to pesticide use.
- In 2020, toxic chemicals were dumped near Saradapally in Jubilee Park, causing another mass fish kill.
- In 2023 and 2025, poisoning was again reported near Saradapally.
These repeated events suggest systemic negligence and lack of accountability.
Ecological Impact
The ecological consequences are severe:
- Loss of biodiversity as multiple species perish.
- Disruption of food chains, affecting birds and other aquatic predators.
- Long‑term contamination of river ecosystems.
Government references:
Governance and Accountability
Local activists allege that unscrupulous traders deliberately poison rivers to collect dead fish for sale. Officials have promised strict action, but enforcement remains weak.
Relevant government links:
Technology and Transparency
Authorities plan to use awareness camps and helplines to report illegal activities. However, questions remain:
- Why are surveillance systems not in place?
- Can AI‑based monitoring tools detect chemical dumping?
- How can communities be empowered to protect rivers?
For IT governance:
Legal Framework
India’s Water (Prevention and Control of Pollution) Act, 1974 prohibits discharge of pollutants into water bodies. Yet enforcement is often lax.
Relevant government link:
Community Response
Residents collected dead fish despite warnings, highlighting the desperation of poor families. Officials urged people not to consume poisoned fish and promised awareness drives in riverine villages.
Broader Implications for Democracy
The incident reflects deeper governance challenges:
- Weak enforcement of environmental laws.
- Lack of accountability for polluters.
- Failure to protect livelihoods of vulnerable communities.
Conclusion
The Teesta River fish deaths are a stark reminder of the fragility of ecosystems and the human cost of negligence. Protecting rivers requires strict enforcement of pollution laws, transparent monitoring systems, and community participation. Without urgent action, such tragedies will continue to erode both ecological balance and public trust.
