HAB is one of serious oceanic disaster in whole world. Shellfish toxin distribution scale is expanding and spreading also. Study of shellfish toxin has been carried out since 1998 in China Sea supported by Ministry of agriculture of China. 247 samples were analysed using both HPLC and Enzyme-Linked-Immunosobent-Assay (ELISA) two methods. Samples collected from yellow sea, East China Sea, South China Sea. Testing by pre-column method results show that a few samples contain PSP. Their main compositions are GTX1, 4, GTX2, 3, in 240 samples only two samples contain low value C1, 4 and STX.

Result to test showed 11 samples -containing DSP in 30 samples. Bullacta exaratas Okadaic acid value are separated 112ng/g  300ng/g

Test to ASP result to 12 samples showed domoic acid was not found. Some suggestions to control Red Tides and shellfish toxin were presented also.
