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 15, 2014)

A large offshore bloom of Karenia brevis, the Florida red tide organism, has been detected this month in the northeast Gulf of Mexico. Last week, satellite images from the Optical Oceanography Laboratory at the University of South Florida showed a patchy bloom up to 60 miles wide and 90 miles long, at least 20 miles offshore between Dixie and northern Pinellas counties in northwest and southwest Florida. Recent satellite images have been unreliable due to cloud cover.  FWC’s Fish Kill Hotline has received numerous reports of a widespread fish kill. 

This week, K. brevis was detected in very low concentrations in several samples collected offshore of Pinellas county. Four samples collected inshore of Manatee and Sarasota counties and one sample collected offshore of Wakulla County contained background concentrations of K. brevis. 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 slow southeast movement of water where the bloom was last detected.

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
