Red tides sighted
*****************
On March 28, staff of the Leisure and Cultural Services Department (LCSD) spotted the first red tide at Silverstrand Beach, Sai Kung. Another red tide was spotted at Clear Water Bay Second Beach, Sai Kung, on April 2 by staff of the LCSD. The red tide at Silverstrand Beach has dissipated, while the red tide at Clear Water Bay Second Beach persists. No associated fish deaths have been reported as of today.
A spokesman for the working group said, "The red tide at Silverstrand Beach was formed by Noctiluca scintillans, while the red tide at Clear Water Bay Second Beach was formed by Scrippsiella acuminata. Both algal species are common in Hong Kong waters and non-toxic."
The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at the fish culture zones of Ma Nam Wat, Kau Sai, Kai Lung Wan, Tai Tau Chau, Leung Shuen Wan, Tiu Cham Wan, Tung Lung Chau and Po Toi O 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.
