Thousands of dead fish wash up at Sungei Buloh Wetland Reserve, Singapore

Thousands of dead grey mullet, a popular farmed fish, washed up at Sungei Buloh Wetland Reserve yesterday, startling visitors there.

In the afternoon, as the high tide went out, dead fish brought in by the tide were left along river banks, though native halfbeak fish in the Sungei Buloh Besar river seemed unaffected.

The Agri-Food and Veterinary Authority also said Singapore’s coastal fish farms in the western Johor Strait had not been hit by die-offs, and no plankton blooms or any abnormalities had been detected.

The agency cautioned it would take enforcement action against farms found to be illegally dumping farm waste into the water.
