With over 80% of Florida's residents residing in coastal counties, many Floridians are frequently affected by algal blooms. Recreational activities like boating, fishing, swimming, and beach-walking are popular with both residents and tourists. In Florida, tourism depends on an abundance of healthy beaches, outdoor recreational activities, and seafood. Harmful algal blooms (HABs) can have unrecognized economic impacts on health care, fisheries, and tourism industries. During a bloom, people may seek medical care for their symptoms, which results in additional health care expenditures. Local county and city governments may be tasked with beach clean-up efforts which may last for months. If red tide toxins accumulate in shellfish, nearby harvesting beds are closed, resulting in revenue losses for the aquaculture industry. Local businesses including hotels and restaurants often report a decline in tourism during HAB events.
