Hundreds of dead fish were found floating along and washed up on the banks of a river in Bishan-Ang Mo Kio Park on Tuesday, alarming residents and causing a stench.

National water agency PUB said in a statement on its Facebook page yesterday that it received a report about several dead fish on the upstream section of the 3km-long river – between Marymount Road and Bishan Road – on Tuesday morning.

It was later found that about 400 Tilapia (Oreochromis sp.) and Mayan Cichlids (Cichlasoma urophthalmus) – freshwater fishes common in the aquarium trade – had died.

Other fish and animal life in the river, including terrapins, were unaffected.

Contractors were sent down to remove the dead fish. The clean-up was completed at 3pm yesterday.

A cluster of dying and dead fish, suspected to be Tilapia and Mayan Cichlids, was spotted in the waterway flowing through Bishan-Ang Mo Kio Park this morning (Feb 5). The PUB has said the deaths could be due to lower levels of dissolved oxygen in the water. There was no suspected water contamination involved.

Lower levels of dissolved oxygen caused by hot and dry weather could have led to the death of about 400 fish at Bishan-Ang Mo Kio Park today (Feb 5), the PUB said in a statement.

The PUB said it received a report of several dead fish at the upstream section of Kallang River at the Bishan-Ang Mo Kio Park this morning. Contractors were activated to clear up the dead fishes and the clean-up was completed at 3pm. The two species of fish affected are Tilapia (Oreochromis sp.) and Mayan Cichlid (Cichlasoma urophthalmus).

Water samples were also collected and laboratory test results show that water quality was not affected and there was no contamination.

The PUB also said it is safe for the public to continue with water activities at the premise and the agency will continue to monitor the situation closely.

Dry, hot weather could have caused fishes’ death: PUB

Hot, dry weather may have caused the death of some 400 fishes in the Kallang River at Bishan-Ang Mo Kio Park on Tuesday.

National water agency PUB said in statement on Wednesday that the recent dry spell could have led to lower levels of dissolved oxygen in the water.

The recent hot weather in Singapore is due to a dry phase of the Northeast Monsoon season, which is predicted to persist for another two more weeks.

Only two types of fish – Tilapias (Oreochromis sp.) and Mayan Cichlids (Cichlasoma urophthalmus) – were affected.

The PUB said the fishes did not die from a drop in water quality or contamination, and it is continuing with its investigations.

Hundreds of dead fish found in Bishan-Ang Mo Kio park river

Hundreds of dead fish were found floating in the river at Bishan-Ang Mo Kio Park by residents on Tuesday, causing a stench in the area that lingered till Wednesday afternoon.

About 400 fish were caught in clumps along the banks or on rocks by the three-kilometre long river, especially on the stretch close to Bishan Road. Many were decomposing under the hot sun.

National water agency PUB said that it was notified about the dead fish on Tuesday morning, and immediately sent contractors to clean up the river. The clean-up was completed by 3pm on Wednesday, the spokesman added.

PUB explained that lower levels of dissolved oxygen in the water caused by recent hot and dry weather could have killed the fish. It said that only two species of fish – Tilapia (Oreochromis sp.) and Mayan Cichlids (Cichlasoma urophthalmus) – were found dead.

Based on the pile of dead fishes in one of the photos, it would appear that at least one Eartheater Cichlid (Geophagus altifrons) was also a victim of this mass mortality event.
