SINGAPORE: 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 and Mayan Cichlids -- 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.
The clean-up of the river began on Tuesday and was completed at 3pm on Wednesday.
The PUB has urged the public to continue with water activities in the river as it is safe for use and the agency will continue to monitor the situation closely.
