A patchy bloom of the Florida red tide organism,Karenia brevis, persists in Southwest Florida.
In Southwest Florida over the past week, K. breviswas observed at background to low concentrations in three samples collected from or offshore of Lee County, and very low to medium concentrations in two samples collected from offshore of Monroe County.
In Northwest Florida over the past week, K. breviswas observed at background concentrations in one sample collected from Franklin County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Fish kills were reported in Monroe County eight miles south of Sandy Key (2/15), in Florida Bay (2/16), and offshore of Marathon Key (2/16 and 2/19). Respiratory irritation was also reported in Monroe County, offshore of Marathon Key (2/19). Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to Monroe counties predict northern, alongshore transport of surface waters and southern, onshore transport of subsurface waters 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.
