*A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from Pinellas to Lee counties.*
Over the past week, Karenia brevis was observed at background to medium concentrations in eleven samples collected from Pinellas County; background to medium concentrations in seventeen samples collected from Manatee County; low to high concentrations in thirty samples collected from Sarasota County; background to low concentrations in five samples collected from Charlotte County; and background to low concentrations in five samples collected from Lee County.
One sample collected from Gulf County this week (Northwest Florida) contained background concentrations of K. brevis.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Over the past week, fish kills affecting multiple species have been reported along Pinellas, Manatee, Sarasota, and Lee counties. Respiratory irritation was reported along Manatee and Sarasota counties. Forecasts for Southwest Florida by the [USF-FWC Collaboration for Prediction of Red Tides] predict net southern movement of surface waters, and southern onshore movement of subsurface waters between southern Pinellas and northern Monroe counties over the next 3 days.
This information, including maps and reports with additional details, is also available on the FWRI Red Tide website. 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.
