Red tide sighted
Friday, April 21, 2023

A red tide has been sighted over the past week, the Inter-departmental Red Tide Working Group reported today (April 21).

Staff of the Leisure and Cultural Services Department spotted a red tide at Stanley Main Beach, Hong Kong Island, today. The red tide persists and no associated fish deaths have been reported as of today.

A spokesman for the working group said, "The red tide was formed by Noctiluca scintillans, which is common in Hong Kong waters and non-toxic."

The AFCD urged mariculturists at Lo Tik Wan, Sok Kwu Wan and Po Toi fish culture zones to monitor the situation closely and increase aeration where necessary.

Red tide is a natural phenomenon. The AFCD's proactive phytoplankton monitoring programme will continue to monitor red tide occurrences to minimise the impact on the mariculture industry and the public.
