Red tide events have been noted in Florida since the 1800s and most certainly occurred prior to European settlement.

People with severe or chronic respiratory conditions such as asthma or chronic lung disease are cautioned to avoid areas with active red tide. If you experience any eye, nose or throat irritation while in an area with red tide, symptoms should go away if you leave the area. The presence of red tide can affect some people and impact fish and marine wildlife. Please like our page and learn interesting facts concerning red tide and other harmful algal blooms in Florida.Red tide is a type of harmful algae bloom (HAB) caused by an increase or “bloom” in the concentration of certain microscopic algae in the water. The FWRI HAB group in conjunction with Mote Marine Laboratory now have a facebook page. Archived status maps can also be found on Flickr. To learn more about various organisms that have been known to cause algal blooms in Florida waters, see the FWRI Red Tide Flickr page. The website also provides links to additional information related to the topic of Florida red tide including satellite imagery, experimental red tide forecasts, shellfish harvesting areas, the FWC Fish Kill Hotline, the Florida Poison Information Center (to report human health effects related to exposure to red tide), and other wildlife related hotlines. This information, including maps and reports with additional details, is also available on the FWRI Red Tide website. For more information on algal blooms and water quality, please visit Protecting Florida Together. Please check our daily sampling map, which can be accessed via the online status report on our Red Tide Current Status page. The next complete status report will be issued on Friday, August 6 th. Status updates and results are posted on the Protecting Florida Together website ( ) and on the Tampa Bay Estuary Program website ( ). įorecasts by the USF-FWC Collaboration for Prediction of Red Tides for Citrus to northern Monroe counties predict net northern transport of coastal surface waters and minimal net movement of subsurface waters in most areas over the next 3.5 days.įWC-FWRI is working closely with the Florida Department of Environmental Protection (FDEP) and other partners on the Piney Point response effort. Respiratory irritation suspected to be related to red tide was reported over the past week in Southwest Florida in Pinellas, Manatee, Sarasota, Charlotte, and Lee counties. Along the Florida East Coast over the past week, K. brevis was not observed.įish kills suspected to be related to red tide were reported in Southwest Florida in Pinellas, Manatee, Sarasota, Charlotte, and Lee counties over the past week.

Samples collected from or offshore of Escambia, Santa Rosa, Okaloosa, Walton, or Franklin counties did not contain K. brevis. In Northwest Florida over the past week, K. brevis was observed at low concentrations offshore of Citrus County (in one sample), background to very low concentrations offshore of Hernando County (in four samples), and background to medium concentrations in and offshore of Pasco County (in 15 samples).Samples collected from or offshore of Collier County did not contain K. brevis. In Southwest Florida over the past week, K. brevis was observed at background to high concentrations in and offshore of Pinellas County (in 34 samples), background concentrations in Hillsborough County (in one sample), background to medium concentrations in Manatee County (in 10 samples), low to high concentrations in Sarasota County (in 21 samples), medium concentrations in Charlotte County (in two samples), and background to medium concentrations in Lee County (in eight samples).Bloom concentrations (>100,000 cells/liter) were observed in 56 samples: seven from Pasco County, 25 from Pinellas County, two from Manatee County, 19 from Sarasota County, two from Charlotte County, and one from Lee County. Over the past week, K. brevis was detected in 96 samples. A bloom of the red tide organism, Karenia brevis, persists on the Florida Gulf Coast.
