Abstract

Harmful micro algal blooms (HABs) are a natural component of seasonal cycle of photosynthetic organisms in marine ecosystems. HABs are considered natural occurring phenomena that can be influenced by anthropogenic activities in coastal areas. Also, global warming, particularly changes in the oceans could increase HAB occurrences, thus enhancing the likelihood of seafood (e.g. shellfish) consumption poisonings [1]. Photosynthetic organisms (e.g. plank tonic microalgae and cyanobacteria) partially sustain aquatic ecosystems through carbon fixation and oxygen production. HABs are often associated with a variety of species (e.g. Pseudonitzschia spp, Dinophysis spp, Alexandrium spp.).
