General methods are used to study the feeding pressure and metabolism of three commercially important bivalves (Crassotrea gigas, Mytilus edulis, Chlamys ferreri) on two harmful red tide dinoflagellates (Alexandrium tamarense, Gymrodinium sp.

Interaction of UV-B radiation enhancement and athracene on the growth of three species of red tide microalgae;

Advances of research on effects of red tide algae on the feeding, egg production and hatching of copepods;

Advances in molecular detection techniques for red tide algae

In this paper in vivo fluorescence excitation spectra were measured and the discrimination method of the red tide algae was established by the similarity index of spectra.

Study on automatic recognition for harmful algae images;

Four species of representative harmful algae from the East China Sea,Skeletonema costatum,Pseudo-nitzschia pungens,Prorocentrum donghaiense and Alexandrium catenella,were choosen as the target species.

Various technics of genetic and molecular markers are extensively used for phylogenetic analysis of red-tide algae providing their morphological identification with a complementary tool and playing an important role in the revelation of the harmful algae diversity.

In a batch culture experiment, it was tested the effects of Pb(Ⅱ) on the growth of 2 species of HAB algaes(Chaetoceros curvisetus, Skeletonema costatum) at different concentrations of micro nutrients(NO 3-N and PO 4-P).

The effect of the ratio variation of nitrate and phosphate on the growth of 3 species of HAB algae (Nitzschia closterium, Chaetoceros curvisetus, Skeletonema costatum) is studied and batch culture experiments are conducted.

In order to understand the mechanism of HAB outbrake to answer why one or several HAB species can overwhelm others and become dominant, both batch culture experiment in laboratory and mesocosm experiment in East China Sea are conducted to study the effects of dissolved inorganic nutrients composition on the growth of common HAB algae in East China Sea.
