# Tamil Nadu forms expert panel to probe mass fish kill in Kosasthalaiyar 2026-08-22T00:26:04+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet Tamil Nadu Environment Minister V.K. Rajeev told the Assembly on Friday that a four-member expert committee has been formed to investigate the mass death of fish in the Kosasthalaiyar river near the Ennore estuary. Replying to a Calling Attention Motion moved by AIADMK floor leader Edappadi K. Palaniswami, the Minister denied that toxic industrial effluents had mixed with the river water, attributing the pollution to sewage from nearby areas. He said the committee has been instructed to submit a detailed report within 10 days. Officials from the Fisheries Department and the Tamil Nadu Pollution Control Board have collected water and dead fish samples for laboratory analysis. A total of 2,150 kg of dead fish has been removed from the Ennore estuary. Mr. Palaniswami said the incident was a serious concern affecting the livelihoods of catamaran and fibreboat fishermen, and demanded a proper inspection by TNPCB officials. Former Environment Minister Thangam Thennarasu called the Kosasthalaiyar-Ennore creek an ecologically sensitive area needing immediate attention, while PMK MLA A. Ganesh Kumar alleged that industries were discharging effluents into the river. ## Indian Opinion Analysis The Kosasthalaiyar river has seen repeated pollution episodes over the past decade, with the Ennore creek being a known discharge point for Chennai's industrial belt. The 2,150 kg of dead fish is significant, but the key figure to watch is the committee's 10-day deadline. The outcome will test whether the state government can credibly distinguish between sewage and industrial effluent, a distinction that determines who pays for cleanup and compensation. The livelihoods of hundreds of fishermen in the Ennore estuary depend on this. Watch for the report due by August 31, 2026. ## Coverage - thehindu.com Straight news report of assembly proceedings with no editorial slant, attributing claims to each speaker.
