Red Tide Status (December 2, 2016)
A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from southern Pinellas to Lee County, with patches observed in Collier and northern Monroe counties.
Over the past week, Karenia brevis was observed in very low to low concentrations in four samples collected from Pinellas County; low to medium concentrations in thirteen samples collected from Manatee County; low to high concentrations in twenty-four samples collected from Sarasota County; very low to high concentrations in two samples collected from Charlotte County; background to medium concentrations in ten samples collected from Lee County; background to low concentrations in two samples collected from Collier County; and very low concentrations in one sample collected from Monroe County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Fish kills affecting multiple species have been reported along Pinellas, Charlotte, Lee, and Collier counties over the past week. Respiratory irritation has also been reported in some areas of Sarasota and Lee counties. Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides show net offshore, southern movement of surface waters, and onshore, southern movement of subsurface waters between southern Pinellas and northern Monroe counties over the next 3 days.

FWC's Red Tide Action Report
Red tide is a naturally-occurring microscopic alga that has been documented along Florida’s Gulf Coast since the 1840’s and occurs nearly every year. Blooms, or higher-than-normal concentrations, of the Florida red tide alga, Karenia brevis, frequently occur in the Gulf of Mexico at this time of year (late summer or early fall). Red tide begins in the Gulf of Mexico 10 to 40 miles offshore and can be transported inshore by winds and currents.
