Not all algae are bad.  In fact, they are a critical link in the food chain and crucial producers of the oxygen that we all breathe.  Cyanobacteria or Blue-Green Algae is always present in the Mississippi Sound.  Under the proper conditions, the algae can bloom and the toxins that some cyanobacteria naturally emit, can become concentrated enough to become harmful, hence the term “Harmful Algal Bloom” or HAB.  Not all algae blooms are considered “harmful.”
