Red tide sightings reported An inter-departmental red tide working group today (September 29) reported three red tide sightings within Hong Kong waters to keep the public well informed of the latest monitoring situation. A spokesman for the working group said a red tide was observed on September 23 at Tai Long Wan, Sai Kung by the Government Flying Service. It was dissipated on September 25. On September 25, staff of the Leisure and Cultural Services Department also reported a red tide sighting at Shek O Beach. The red tide dissipated on September 29. The two red tides were formed by Scrippsiella trochoidea. It had been sighted in Hong Kong waters before and was non-toxic. Another red tide case occurred on September 25 at Yim Tin Tsai (East) fish culture zone and Shuen Wan Hoi, Tolo Harbour. It was reported by staff of the Environmental Protection Department and mariculturists of the fish culture zone. The red tide, formed by a species belongs to the Family Haematococcaceae, had dissipated the following day. The species was rare in Hong Kong waters and was non-toxic. All three red tides had led to no associated fish kill. The spokesman said red tide was a natural phenomenon and AFCD's pro-active and comprehensive phytoplankton monitoring programme would continue monitoring red tide occurrence to minimise its impact on mariculture industry. |
