Red Tide Status Report (March 2, 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 one sample collected from Pinellas County, background concentrations in one sample collected offshore of Hillsborough County, background to medium concentrations in eleven samples collected from Sarasota County, background to low concentrations in six samples collected from Charlotte County, background to medium concentrations in fifteen samples collected from Lee County, and background to very low concentrations in three samples collected from Collier County.

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

Numerous fish kill reports were received for Lee and Collier counties over the past week. Areas impacted in Lee County include Big Carlos Pass, Big Hickory Island, Bonita Beach, Captiva Island, Carlos Point, Cayo Costa, Estero Island, Fort Myers Beach, Little Hickory Island, Lovers Key State Park, Pine Island Sound, San Carlos Bay, Sanibel, and offshore of St. James City.

Areas impacted in Collier County include Barefoot Beach, Delnor-Wiggins Park, Vanderbilt Beach, and Wiggins Pass.

Respiratory irritation was reported in Sarasota County at Manasota (3/1), Nokomis (3/1 – 3/2), Venice (3/2), and Venice North Jetty (2/28 – 3/2) beaches; in Lee County at Bonita (3/2), Bowman’s (2/25), Captiva (2/28, 3/2), Causeway Islands (2/26), Gasparilla Island State Park South Lighthouse (3/2), Lovers Key State Park (2/26 – 2/27, 3/2), and Lynn Hall (2/26) beaches; and in Collier County at Barefoot (2/27, 3/1, 3/2) and Delnor-Wiggins State Park (3/1, 3/2) beaches.

Forecasts by the USF-FWC Collaboration for Prediction of Red TidesExternal Website for Pinellas to Monroe counties predict southern, offshore transport of surface waters and southern, onshore 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

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 (FDACSExternal Website), 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.
