Red tide sighted
****************
The red tide was spotted by the public on September 8 at the Sham Wan Fish Culture Zone. The red tide has dissipated and no associated fish deaths 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 Tap Mun, Kau Lau Wan, Sham Wan, Wong Wan, Sha Tau Kok, Ap Chau, Kat O, O Pui Tong, Sai Lau Kong, Yim Tin Tsai, Yim Tin Tsai (East), Yung Shue Au, Lo Fu Wat and Mirs Bay 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.
