Skeletonema costatum%harmful algal bloom%te mperature%irradiance%salinity
3-factor experiment was used to study the combined effects of temperature, irra diance and salinity on the growth of an HAB species diatom Skeletonema costatu m (Grev.) Cleve. The results showed that temperature (12, 19, 25, 32℃), irradian ce ((0.02, 0.08, 0.3, 1.6)×1016quanta/(s*cm2)) and salinity (10, 18, 25, 30, 35) significantly influenced the growth of this species. There were interactive effects between any two of and among all three physical factors on the growth. In the experiment, the most optimal growth condition for S. costatum was te mpar ature of 25℃, salinity of 18-35 and irradiance of 1.6×1016 quanta/(s* cm2). The results indicated S. costatum could divide at higher rate and were more lik ely to bloom under high temperature and high illumination from spring to fall. It was able to distribut e widely in ocean and estuary due to its adaptation to a wide range of salinitie s.
