Abstract

The recent 30 years HAB statues and monitor work in East China Sea were summarized, total 151 HAB events were recorded and 204 HAB species were found exiting in East China Sea. Some wide-range HAB caused great loss to the economic and fishery resources. The ecological character of some important HAB species and recent active HAB specie Prorocentrum dentatum is described. Some advice about the quality control in monitoring work and the field monitoring experience are submitted for the relative works.
