Red tide sighted
Friday, July 21, 2017
A red tide has been sighted over the past week, an inter-departmental red tide working group reported today (July 21).
The red tide was seen by staff of the Marine Department in the East Lamma Channel yesterday (July 20).
The red tide still persists but no associated death of fish has been reported.
A spokesman for the working group said, "The red tide was formed by Thalassiosira pseudonana, which is commonly found in Hong Kong waters and non-toxic."
The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at Ma Wan, Cheung Sha Wan, Lo Tik Wan, Sok Kwu Wan and Po Toi 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 monitoring red tide occurrences to minimise the impact on the mariculture industry and the public.
