　　On the basis of historical records and investigated data in recent years, the frequency of harmful algal blooms(HABs) has been increasing in the Zhejiang coastal waters.The scale of HABs in the last decade becomes much more extensive and toxic species have been recorded more frequently than ever before.Before the decade of 70s of last century, the dominant species in phytoplankton community were mainly dinoflagellates and diatoms such as species in genera Noctiuca, Skeletonema, Chaetoceros, Coscinodiscus, Rhizosolenia, Thalassiosira etc.Since 80s of last century, more and more harmful and toxic species such as Prorocentrumdonghaiense, Kareniamikimotoi,and species of the genus Alexandrium, become dominant in phytoplankton community and formed massive blooms although diatom still keep common in the coastal waters of Zhejiang province, China.
