Residents queasy over fishy pong
6th February 2014;

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.

Hundreds of dead fish found in Bishan-Ang Mo Kio park river
By David Ee, 5th February 2014;

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.
