A bloom of the Florida red tide organism, Karenia brevis, was observed from Sarasota to Lee counties in Southwest Florida.
In Southwest Florida over the past week, Karenia brevis was observed at background concentrations in one sample collected from Pinellas County, low concentrations in one sample collected from Manatee County, background to high concentrations in sixteen samples collected from Sarasota County, medium to high concentrations in seven samples collected from Charlotte County, and background to high concentrations in eleven samples collected from Lee County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Numerous reports of fish kills and respiratory irritation in Sarasota, Charlotte, and Lee counties were received over the past week. Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict southern, alongshore transport of surface and subsurface waters from Pinellas to Lee counties over the next three 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.
