Red tide sighted
Friday, April 16, 2004

A red tide has been sighted in Hong Kong waters in the past few days, an inter-departmental red tide working group reported today (April 16).

Fishermen of the Sha Tau Kok fish culture zone observed the appearance of a red tide at Sha Tau Kok Hoi on April 12. The red tide dissipated yesterday.

"The red tide was formed by Skeletonema costatum which is non toxic to fish and common in Hong Kong waters," a working group spokesman said.

Red tide is a natural phenomenon. The Agriculture, Fisheries and Conservation Department's proactive phytoplankton monitoring programme will continue monitoring red tide occurrences to minimise the impact on the mariculture industry.
