Red tide sighted
****************
On December 9, staff of the Environmental Protection Department spotted two red tides at Angler's Beach and Gemini Beaches. Both red tides have dissipated. No associated fish deaths have been reported as of today.
A spokesman for the working group said, "Both red tides were formed by Phaeocystis globosa, which is commonly found in Hong Kong waters. According to literature overseas, the algal species can produce foam that may affect fish."
The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at the Ma Wan fish culture zone 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.
