Impacts of Harmful Algal Blooms (HABs) of
Karenia brevis in the Gulf of Mexico
• HABs=The rapid growth of toxic or nuisance algae
• Impacts of Karenia brevis may include:
o Discolored water
o Death of fish, mammals, reptiles and birds exposed to
toxins
o Human illness- contaminated shellfish and/or
respiratory irritation
o Economic impacts- Reduced seafood sales and/or
coastal tourism

• K. brevis blooms have been documented in the GOMX since at least
the 1700s and are most frequent in southwest Florida
• At least one bloom, almost every year for the past 30 years
• Bloom “season” = August 1 to early February
• Blooms last weeks, months or over a year
