Article
Tolo Harbor is a nearly land-locked body of water located northeast of Hong Kong with only one narrow exit opening to the sea at Mirs Bay. Rapid urbanization accompanied by various anthropogenic stresses caused the frequent occurrences of red tides and associated fish kills, as well as coral deaths, in Tolo Harbor in the late 1980s. To stop “Hong K...
