More than 1,000 dead fish were found washed up on Pasir Ris beach on Saturday. The Agri-Food and Veterinary Authority (AVA) said the fish are likely to have died due to high levels of plankton, the result of heavy rain.

Decomposing plankton can lead to oxygen starvation in the water. The AVA said the fish, mostly tiger garoupas, were from nearby fish farms. The National Environment Agency has conducted checks in the vicinity and found no trace of an oil spill or chemical discharge into the sea. It has collected water samples for further analysis.
