Florida Fish & Wildlife Red Tide Status: Friday, July 21, 2017
Florida Fish & Wildlife Conservation Commission red tide bulletin at 2:43 PM 7/21/2017.
Red Tide Status (July 21, 2017)
The Florida red tide organism, Karenia brevis, was present in background concentrations on the West Coast of Florida.
Over the past week, Karenia brevis was observed at background concentrations in one sample collected from Gulf County, and background concentrations in three samples collected from Pinellas County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tidespredict net northern transport of surface waters and no net movement of subsurface waters from Pinellas to northern Monroe counties over the next three days.” For more information, please see FWC.
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|
