Red tide sighted
****************
The red tide was spotted by staff of the Environmental Protection Department on April 25 at Tolo Harbour including Yim Tin Tsai fish culture zone. The red tide has dissipated. No associated death of fish has been reported.
A spokesman for the working group said, "The red tide was formed by Gonyaulax polygramma, which is commonly found in Hong Kong waters and non-toxic."
The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at Yim Tin Tsai, Yim Tin Tsai East, Yung Shue Au and Lo Fu Wat 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.
