Red tides sighted

     Three red tides have been sighted in Hong Kong waters over the past week, an inter-departmental red tide working group reported today (December 12).

     The first red tide was spotted by staff of the Agriculture, Fisheries and Conservation Department (AFCD) at Hoi Ha Wan on December 7. Two other red tides were reported by members of the public and staff of the Leisure and Cultural Services Department at Double Haven (Yan Chau Tong) and Cheung Chau Kwun Yam Beach respectively on December 8.

     The red tides have already dissipated. No associated death of fish has been reported in these occurrences so far.

     "All the red tides were formed by Noctiluca scintillans, which is non-toxic and commonly found in Hong Kong waters," a spokesman for the working group said.

     The AFCD urged mariculturists at Sha Tau Kok, Ap Chau, Kat O, O Pui Tong, Sai Lau Kong, Tap Mun, Kau Lau Wan, Wong Wan, Sham Wan, Ma Wan, Cheung Sha Wan, Lo Tik Wan and Sok Kwu Wan fish culture zones to monitor the situation closely.
     Red tide is a natural phenomenon. The AFCD's proactive phytoplankton monitoring programme will continue monitoring red tide occurrences to minimise the impact on the mariculture industry and the public.
