More dead fish were found in Shing Mun River in Sha Tin over the weekend, adding to the mysterious death of thousands of the creatures last month, according to reports.
Authorities are yet to reach a conclusion on the reason behind the mass fish deaths despite holding an inter-departmental meeting, RTHK reported.
Photos uploaded by a netizen Sunday onto Facebook showed dead fish over several hundreds of meters of a river bank near a residential development in Tai Wai.
Some citizens noted that similar scenes were captured by the cameras a few days ago.
The bad smell brought by the dead fish has annoyed local residents for quite some time, and some of them have even complained to their district councilors about potential sanitation issues.
The Food and Environmental Hygiene Department said a contractor has picked up about a ton of garbage, including dead fish, plants and other types of rubbish on Sunday.
The Agriculture, Fisheries and Conservation Department, meanwhile, is reported to have sent its employees to collect water samples for lab tests.
According to the Drainage Services Department, cleaning work has been going on in the past few days.
Apple Daily quoted a cleaning worker as saying that more than a hundred bags, each weighing about three kilograms, had been collected from the Shing Mun River in recent days.
Most of the dead fish were croaker and mullet, according to the report.
