A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida.

In Southwest Florida over the past week, K. brevis was observed at very low concentrations in one sample collected from Charlotte County, background to medium concentrations in 11 samples collected from Lee County, and background to low concentrations in three samples collected from Collier County.

In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample collected from Escambia County and one sample collected from Gulf County.

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

Over the past week, fish kills were reported in Southwest Florida in Lee County (at Bonita, Fort Myers and Lighthouse beaches, and Lovers Key State Park) and Collier County (at Barefoot Beach). Respiratory irritation was reported over the past week in Lee County (5/2 at Lovers Key State Park) and Collier County (5/7 at Barefoot Beach).

Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net southwestern movement of surface waters and southeastern movement 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.

To learn more about various organisms that have been known to cause algal blooms in Florida waters, see the FWRI Red Tide Flickr page. Archived status maps can also be found on Flickr.

The FWRI HAB group in conjunction with Mote Marine Laboratory now have a Facebook page.  Please like our page and learn interesting facts concerning red tide and other harmful algal blooms in Florida.
