Red tide sightings reported An inter-departmental red tide working group today (October 5) reported five 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 all five red tides were formed by Scrippsiella trochoidea which had been sighted in Hong Kong waters before and was non-toxic. He noted that the red tides had not led to any fish kill. A red tide was observed on September 29 at Stanley Beach by staff of the Leisure and Cultural Services Department and red flag was hoisted. It had dissipated the next day. On September 29, Marine Police also reported a red tide sighting at Tolo Channel near Lo Fu Wat. The red tide subsided afterward but emerged again on October 2. The Agriculture, Fisheries and Conservation Department (AFCD) had alerted mariculturists at Lo Fu Wat and Yung Shue Au on possibility of oxygen depletion in the water. Another red tide sighting was reported on September 29 by staff of the Hong Kong University of Science and Technology along the coastal areas of Port Shelter. It dissipated on October 1. The forth red tide sighting was reported by mariculturists at O Pui Tong and Kat O fish culture zones on September 30 and October 3 respectively. The last red tide sighting was reported yesterday (October 4) by staff of AFCD at Nam Fung Wan in Long Harbour. The spokesman said the working group would keep on monitoring the situation at Lo Fu Wat, O Pui Tong and Kat O fish culture zones and Nam Fung Wan, where red tides still persisted. 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. |
