摘　　要：Competition among HAB (Harmful Algal Bloom) species Dinoflagellate Alexandrium tamarense , Raphidophyte Heterosigma carterae , and Diatom Skeletonema costatum was studied in the laboratory. Experiments with these three major HAB species under combinations of different salinities (10, 18, 25, 30, 35) and temperatures (19℃, 25℃) were carried out. The results showed that S. costatum successfully competed with the other two species at salinities of 18, 25, 30, and 35 at temperatures of 19℃ and 25℃. However, H. carterae showed its advantage at low salinity of 10 and became the single dominant species at salinity 10 and 25℃. A. tamarense could not compete successfully with the other two species especially at low salinities. However, it could remain at low density in the presence of higher densities of other algae.Competition among HAB (Harmful Algal Bloom) species Dinoflagellate Alexandrium tamarense , Raphidophyte Heterosigma carterae , and Diatom Skeletonema costatum was studied in the laboratory.
