-------------------------------------------------------------------------------- Overview of the period 2020/05/29 - 2020/06/05 A red tide has been sighted over the past week, an inter-departmental red tide working group reported today (June 5). The red tide was spotted by a mariculturist on June 2 at Tolo Harbour including Yim Tin Tsai and Yim Tin Tsai (East) fish culture zones. The red tide still persists. No associated death of fish has been reported. A spokesman for the working group said, "The red tide was formed by Scrippsiella trochoidea, 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.
