Red Tide Current Status

This summary report of current red tide conditions around Florida includes a map of sampling results and regional status reports.

 

Red Tide Summary (August 22, 2014)

A large offshore bloom of Karenia brevis, the Florida red tide organism, has been detected this month in the northeast Gulf of Mexico.  Satellite images from the Optical Oceanography Laboratory at the University of South Florida showed a patchy bloom at least 20 miles offshore between Dixie and northern Pinellas counties in northwest and southwest Florida. FWC’s Fish Kill Hotline has received numerous reports of a widespread fish kill. 

Karenia brevis was detected in background concentrations in one water sample analyzed from offshore of Walton County and background to medium concentrations in the bloom area offshore of Dixie, Levy, Citrus, and Hernando Counties.  In addition, K. brevis was detected in background to very low concentrations in eight samples collected in, and alongshore of, Pinellas and Sarasota counties in southwest Florida. No bloom concentrations of red tide have been detected alongshore or inshore of any of the areas sampled. 

Forecasts by the Collaboration for Prediction of Red Tides show water movement proceeding south and slightly away from the coast for the next several days. 

Additional samples collected throughout Florida this week did not contain K. brevis.

Key for Results

Description Karenia brevis cells/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
