Objectives
To study lethal and sub-lethal effects of red-tide organisms on local cultured marine fish, and set up a warning system for mariculturalists during toxic red-tide blooms; to utilize temporal qualitative and quantitative changes in ecological guilds of the marine benthic community; to assess the status of man-induced degradation of water around the Cape-D'Aguilar peninsula and Southern Water Control Zone with the aim of setting water quality standards and assessing effects of dumping when the Marine Waste Dumping Zone off south-eastern waters of Hong Kong is gazetted thus providing a reference with which to compare the magnitude of environmental degradation/improvement in other marine spots in Hong Kong related to the long term 'clean-up' measures implemented by Environmental Protection Department, particularly in the Tolo Harbour/Channel area; to monitor the dynamics and productivity of established phytoplankton pollution-indicator species in terms of physico-chemical and microbiological water quality for assessing effects of pollution in the Southern Water Control Zone.
