Red tide sighted
Friday, June 23, 2017
A red tide has been sighted over the past week, an inter-departmental red tide working group reported today (June 23).
The red tide was reported by staff of the Agriculture, Fisheries and Conservation Department (AFCD) at Tolo Harbour (including Yim Tin Tsai fish culture zone) yesterday (June 22).
The red tide still persists and no associated death of fish has been reported.
A spokesman for the working group said, "The red tide was formed by Chaetoceros salsugineum, which is commonly found in Hong Kong waters and non-toxic."
The 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 monitoring red tide occurrences to minimise the impact on the mariculture industry and the public.
