Florida Fish & Wildlife Conservation Commission red tide bulletin at 2:31 PM 6/22/2018.
Red Tide Status Report (June 22, 2018)
A patchy 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 background concentrations in two samples collected from or offshore of Pinellas County, background to low concentrations in four samples collected from Manatee County, low to high concentrations in thirty-one samples collected from Sarasota County, very low to medium concentrations in three samples collected from Charlotte County, background to medium concentrations in two samples collected from Lee County, and very low to low concentrations in six samples collected from Collier 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 Pinellas County (Caladesi Island), Sarasota County (Caspersen Beach, Crescent Beach, Lido Key, Little Sarasota Bay, Manasota Beach, Nokomis Beach, Service Beach, Siesta Key, Turtle Beach, Venice Beach, Venice North Jetty), Charlotte County (Gasparilla Sound, Stump Pass Beach), Lee County (Boca Grande Beach, Gasparilla Island Beach, Gasparilla Island Range Lighthouse), and Collier County (Big Marco Pass, Factory Bay, South Marco Island). Respiratory irritation was reported over the past week in Manatee County (6/15 and 6/22 at Coquina Beach), Sarasota County (6/14-6/15, 6/19 at Lido Key; 6/16 and 6/19-6/21 at Manasota Beach; 6/15-6/19 and 6/21 at Nokomis; 6/15-6/17 and 6/20-6/21 at Siesta Key; 6/14-6/17 and 6/19-6/21 at Venice Beach; 6/15-6/21 at Venice North Jetty), Charlotte County (6/18 at Caspersen Beach), and Lee County (6/14-6/15 and 6/19-6/21 at Gasparilla Island Range Lighthouse).
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net southern movement of surface waters and southern, onshore movement 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.
