Red Tide Status Update for August 17, 2018
FWC released the Red Tide Status Report this week.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 5:54 PM 8/17/2018.
Red Tide Status Report (August 17, 2018)
“A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida and currently extends along ~130 miles of coastline. Observations of >1,000,000 K. brevis cells per liter (“high” concentrations) continue to occur at coastal and inshore sites from Manatee to Collier counties, although cell concentrations decreased in parts of Manatee, Sarasota, Lee, and Collier counties relative to last week.
Coastal currents important for transporting cells of K. brevis continue to alternate between predominantly northern or southern flow. K. brevis was observed in Pinellas County (for the second week in a row), and additional sampling there and in Hillsborough County indicated that concentrations were below 100,000 cells per liter in all samples examined. More specific details are provided below.
- In Southwest Florida over the past week, K. brevis was observed at background to low concentrations in Pinellas County, very low concentrations in or offshore of Hillsborough County, background to high concentrations in Manatee County, background to high concentrations in or offshore of Sarasota County, background to high concentrations in or offshore of Charlotte County, background to high concentrations in or offshore of Lee County, and very low to high concentrations in Collier County. For additional information, view the southwest coast report and map .
- In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample collected from Santa Rosa County. For additional information, view the northwest coast report and map .
- Additional samples collected along the east coast of Florida over the past week did not contain K. brevis. For additional information, view the east coast report and map .
Over the past week, reports were received for multiple locations in Pinellas, Manatee, Sarasota, Charlotte, Lee, and Collier counties. More detailed information is available at /fishkill.
Respiratory irritation was reported over the past week in Pinellas County, Manatee County, Sarasota County, Lee County, and Collier County. For additional information, view the southwest coast report .
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict variable movement of surface waters with net northern transport expected close to shore, and net southeastern transport of subsurface waters over the next three days.”

Key for Results
|Description||Karenia breviscells/liter||Possible Effects (K. brevis only)|
|NOT PRESENT – BACKGROUND||background levels of 1,000 cells or less||None anticipated|
|VERY LOW||>1,000 to 10,000||Possible respiratory irritation; shellfish harvesting closures > 5,000 cells/L|
|LOW||>10,000 to 100,000||Respiratory irritation, possible fish kills, and bloom chlorophyll probably detected by satellites at upper limits|
|MEDIUM||>100,000 to 1,000,000||Respiratory irritation and probable fish kills|
|HIGH||>1,000,000||As above plus discoloration|

Reports are updated on Friday afternoon except during holidays, in which case the report will be released on the closest day. Additional information, if available, is provided on Wednesday afternoon. To receive an e-mail when the current status has been updated, visit our subscription area.
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. Red tide begins in the Gulf of Mexico 10 to 40 miles offshore and can be transported inshore by winds and currents.
FWC Actions and Partnerships:
- FWC operates the toll-free fish kill hotline. To report fish kills, contact the FWC Fish Kill Hotline at 800-636-0511 or submit a report online. Reports from this hotline help FWC researchers track and better understand the impact of red tide in Florida.
- FWC remains available to local agencies and partners in affected areas, including area business and tourism groups in southwest Florida. Any local agency or group that has any questions or concerns can contact Kelly Richmond from the FWC at 727-502-4784.
- FWC continues to partner with the Florida Department of Health to advise residents and visitors of any potential health impacts. Residents and visitors can contact the DOH’s aquatic toxin experts at 850-245-4250 or contact their local health department for any concern about health safety.
- FWC’s Fish and Wildlife Research Institute and Mote Marine Laboratory work together to monitor Karenia brevis. This cooperative effort is designed to help mitigate the adverse impacts of red tide. This joint research program that includes red tide monitoring, research and public outreach and education has resulted in better tools and ongoing monitoring for red tides along the Gulf Coast.
- In partnership with the FWC, the Collaboration for Prediction of Red Tides (CPR) at the University of South Florida offer a new Harmful Algal Bloom (HAB) tracking tool that generates a 3.5-day forecast of the bloom trajectories.
- To protect public health, FWC’s Fish and Wildlife Research Institute’s Harmful Algal Bloom (HAB) group closely monitors the status of K. brevis on Florida’s coasts, providing technical support to the Florida Department of Agriculture and Consumer Services (FDACS), the agency that regulates approved shellfish harvesting areas.
- Since 2000, FWC’s Fish and Wildlife Research Institute established a Red Tide Offshore Monitoring Program, which is a volunteer program for citizens to help collect water samples from routine collection points and sites reported for suspected harmful algal blooms (HABs).The timely sampling by volunteers allows researchers to provide an early warning of offshore algal blooms and investigate reported events as they occur. The Program needs volunteers to collect samples from all coastal Florida counties. To view more information visit, Red Tide Offshore Monitoring Program or use the Volunteer SignUp Form.
