21st July 2015;
About 800 to 900 fish were found dead at the Kallang River at Bishan-Ang Mo Kio Park, but the water quality is normal, said Singapore’s water agency PUB.
In a statement, PUB said it was alerted to the problem on Monday (Jul 20) at about 7.40pm. “A site check was carried out immediately and NEA’s contractors were activated to remove the dead fish. Clean-up operations which commenced since last evening at the affected stretch of the river are largely completed,” PUB said on Tuesday.
Laboratory tests showed that the raw water quality, including dissolved oxygen levels, is within normal range, the agency stated.
Most of the fish affected are cichlids (F. Cichlidae). Specimens have been sent to AVA for examination, PUB said. Investigations on the cause are still ongoing.
“As of now, the water quality of the river in Bishan Park is normal, live fishes can be seen in the water and the public can continue with their activities at Kallang River @ Bishan-Ang Mo Kio Park. PUB will continue to monitor the situation,” a PUB spokesperson said
