The recent rise of red tide harmful algal blooms has induced ecosystem degradation, economic losses, and aquaculture damage, yet little is known on prevention and mitigation of red tides. Actual control methods involve physical, chemical, and biological processes, with varying success. Here, we review physical, chemical, and biological control methods applicable to red tide species in marine and estuarine water bodies. We discuss mechanisms of algal blooms outbreak and their applications to prevent outbreaks.
