Harmful Algal Blooms (HABs) are the result of the rapid multiplication of a single species of microorganisms known as photosynthetic microalgae. This proliferation reaches millions of cells per liter and can be colored by pigments on the cell surface, hence the popular name “Red Tide.” Those blooms produced by microalgae that are present in different oceans across the globe and are capable of producing potent toxins are termed Harmful Algal Blooms, a term coined by the Intergovernmental
