2.1 Distribution of some toxic species Alexandrium Before After 2000 2000 After 2000 Alexandrium blooms in Chinese coasts Lu, et al. 2014

Blooms of Karenia mikimotoi in the Chinese coasts Before 2000 Karenia mikimotoi Since 1998, nearly 90 blooms caused by this species occurred in China. The massive bloom After 2000 of Karenia mikimotoi in South China Sea in 1998 and in the East China Sea in 2005, 2012 resulted in the heavy loss of fish farming (http://www.soa.gov.cn).

2.4 New Research Projects 2.4 New Research Projects

Department of Science and Techonology National key research and development program 1: Study of Causative Mechanism, Early Warning, Monitoring strategy and Mitigation on Green Tide ( Ulva prolifera ) has been initiated from 2016

Karenia mikimotoi blooms the ECS in 2012 caused 2 billion RMB(~30 million USD) due to kills of cultured abalone

Phaeocysts globosa blooms in 2015 affected seviously on cooling system of power plant

Department of Science and Techonology National key research and development program 2: Study of Causative Mechanism, Early Warning, Monitoring strategy, Mitigation on Target HABs has been initiated from 2016
