What is blue-green algae?

Blue-green algae are a type of bacteria common in Florida’s freshwater environments. A bloom occurs when the rapid growth of algae causes an accumulation of individual cells that discolor the water and often produce floating mats that emit unpleasant odors.

Some environmental factors that contribute to blue-green algae blooms are sunny days, warm water temperatures, calm water conditions, and excess nutrients. Flowers can appear all year round but are most common in summer and fall. Many types of blue-green algae can produce toxins.

Is it harmful?

Blue-green algae blooms can impact human health and ecosystems, including fish and other aquatic animals.
