Algae update for Lower Manatee River, Perico Bayou and Perico Preserve

There is still no indication of red tide in local waters. However, blue-green algae and brown algae has become pervasive in the Lower Manatee River, Perico Bayou and Perico Preserve, resulting in a modest fish kill, primarily mullet, as a result of heavy algae bloom concentrations. We are working with the Florida Department of Environmental Protection to determine the cause, and FDEP has indicated they will be collecting more samples this week in this vicinity. Additional updates will be made available as more information is received from FDEP.

Florida DEP has been regularly monitoring local water conditions by taking samples and having them analyzed, then posting results to DEP’s Algal Bloom website. The site is a valuable resource to check recent water quality conditions around the area, and it offers information on various algal blooms in Florida. To help expedite that process, Manatee County Environmental Protection staff has agreed to assist Florida DEP by collecting and providing local water samples to DEP’s district office in Tampa.

Manatee County Environmental Protection (EP) has confirmed the presence of some cyano-type algae in isolated areas of the Manatee River. The EP team notes that this kind of algal bloom is typical during the late spring in early summer, when temperatures warm and steady rain follows a prolonged dry period. Over time, the algae breaks down and disappears.

Some — not all — algae can produce toxins that can contribute to environmental problems and affect public health. Residents and visitors may report a suspected bloom at, as well as through a new toll-free number at 1 (855) 305-3903.

Red tide update (local)

Throughout the year Manatee County Parks and Natural Resources does a morning “sweep” of our public beaches, clearing small clumps of grass and seaweed that wash ashore each night. Our Property Management teams will continue their daily effort to keep our public beaches, parks and preserves clean and clear from trash and debris.

In the unfortunate event that a bloom is more widespread and impacts residential areas, County leaders will discuss resuming the Nets to Neighbors program that provides cleanup resources and additional waste hauling to neighborhoods that are directly impacted. The county also stands ready to expand that effort when and if the Board provides that direction.

Note: Red tide is a naturally occurring microscopic alga that's been documented along Florida’s Gulf Coast since the 1840s. It occurs nearly every year. Blooms, or higher-than-normal concentrations

Red Tide Health & Safety Information

According to the Florida Department of Health, people with severe or chronic respiratory conditions should avoid red tide areas.

Some people may experience eye, nose, and throat irritation, as well as coughing, wheezing, and shortness of breath when on the beach or in an area near a red tide bloom, particularly when winds are blowing onshore. 

Swimming can be safe, but some people may experience skin irritation or burning eyes. If you experience these symptoms, get out of the water and wash off thoroughly. You should not swim in the water with dead fish.
