Effect of salinity and light intensity on the growth of chattonella (raphidophyceae)
Harmful algal bloom is a natural phenomenon referring to drastic increase in abundance of phytoplankton. In Malaysian water, Chattonella spp. are members of the Raphidophytes that previous reported as harmful algal that associated with bloom event in Johor in 2002. In this study, clonal culture of C...
