Red Tide Report 3.10.17

A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from southern Pinellas to Lee counties.

Over the past week, Karenia brevis was observed at very low to low concentrations in four samples collected from Pinellas County; background to low concentrations in eight samples collected from Manatee County; background to medium concentrations in twenty-nine samples collected from Sarasota County; very low to low concentrations in two samples collected from Charlotte County; background to low concentrations in six samples collected from Lee County; and background concentrations in one sample collected from Collier County.

Additional samples collected throughout Florida over the past week did not contain K. brevis.

A small fish kill was reported 3/7 at Coquina Beach (Manatee County). Over the past week, respiratory irritation was reported at Nokomis (Sarasota County), Manasota Beach (Charlotte County), and Captiva (Lee County). 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 from Pinellas to northern Monroe 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.
