Red tide sighted
****************
     A red tide has been sighted over the past week, the Inter-departmental Red Tide Working Group reported today (July 31).

     Staff of the Leisure and Cultural Services Department spotted a red tide at Silverstrand Beach, Sai Kung, on July 30. The red tide has dissipated and no associated deaths of fish have been reported as of today.

     A spokesman for the working group said, "The red tide was formed by Levanderina fissa, which is commonly found in Hong Kong waters and non-toxic."

     The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at Kau Sai, Ma Nam Wat, Leung Shuen Wan, Tai Tau Chau, Tiu Cham Wan, and Kai Lung Wan 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.
