incidents appeared in the first six months of 1998 with the most serious events during the period 19 March
to 17 April (Anderson, 1998). This unusually devastating red tide resulted in the worst fish kill in Hong
Kong's history—it destroyed over 80% (3,400 t) of cultured fish stock, with an estimated loss of more
than HK$312 million (Dickman, 1998; Yang et al., 2000). This massive red tide in Hong Kong's southern
waters is related to algal bloom transport; it was reported that the algal bloom appeared first in the northeast
Mirs Bay, and then appeared to be transported southward into Port Shelter, and further westward to
Lamma Island, where the most severe fish kill occurred (Fig. 8.43).
