The Punjab Pollution Control Board (PPCB) has concluded its investigation into fish deaths in the Sutlej River near Harike head works in Ferozepur district, India, ruling out industrial pollution as the cause. The board's tests showed normal oxygen and acidity levels, indicating suitable conditions for aquatic life.
- 01PPCB investigation found no evidence of industrial pollution causing fish deaths.
- 02Normal oxygen levels (6.2–7.7 mg/L) and pH levels (6.8 to 7.5) were observed.
- 03Fish mortality during breeding season in April and May is common.
- 04Samples were too decomposed to identify specific causes of death.
- 05Further investigations are ongoing to determine localized factors.

The Punjab Pollution Control Board (PPCB) has investigated the recent fish deaths in the Sutlej River near Harike head works in Ferozepur district, India, following reports of dead fish received on April 3. A team from the PPCB, along with fisheries experts, conducted field observations the next day, confirming dead fish at various points downstream but not upstream. Testing revealed normal levels of Dissolved Oxygen (DO) ranging from 6.2–7.7 mg/L and pH levels between 6.8 and 7.5, both suitable for aquatic life. The board stated that fish mortality is common during the breeding season in April and May. Analysis of heavy metals and pesticides showed no severe toxicity, and fish samples were too decomposed to determine the exact cause of death. The PPCB continues to investigate potential localized causes for the fish deaths.
