More Red Tide for SW Florida

A patchy bloom of the red tide organism, Karenia brevis, persists in Southwest Florida. Over the past week, K. brevis was detected in 63 samples. Bloom concentrations (>100,000 cells/liter) were observed in 11 samples: eight samples from Pinellas County (including two samples with high concentrations of >1 million cells/liter), two samples from Manatee County, and one sample from Charlotte County. Additional details are provided below.

  • In Southwest Florida over the past week, K. brevis was observed at very low to high concentrations in Pinellas County, very low and low concentrations in Hillsborough County, background to medium concentrations in Manatee County, background concentrations in Sarasota County, very low to medium concentrations in and offshore of Charlotte County, background to very low concentrations in and offshore of Lee County, and background to very low concentrations in and offshore of Collier County.
  • In Northwest Florida over the past week, K. breviswas not observed.
  • Along the Florida East Coast over the past week, K. brevis was not observed.

In Southwest Florida over the past week, fish kills suspected to be related to red tide were reported in Pinellas, Hillsborough, and Manatee counties. For more details, please visit: https://myfwc.com/research/saltwater/health/fish-kills-hotline/.

Respiratory irritation was reported over the past week in Southwest Florida in Pinellas County. For current information, please visit: https://visitbeaches.org/.

Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict northwestern movement of surface waters and variable transport of subsurface waters in most areas over the next four days.

FWC-FWRI is working closely with the Florida Department of Environmental Protection (FDEP) and other partners on the Piney Point response effort. Status updates and results are posted on the Protecting Florida Together website  (https://protectingfloridatogether.gov/PineyPointUpdate) and on the Tampa Bay Estuary Program website (https://shiny.tbep.org/piney-point/).

The next complete status report will be issued on Friday, June 25th. Please check our daily sampling map, which can be accessed via the online status report on our Red Tide Current Status page. For more information on algal blooms and water quality, please visit Protecting Florida Together.

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.
