Florida Fish & Wildlife Red Tide Status: Friday, August 18, 2017
Florida Fish & Wildlife Conservation Commission red tide bulletin at 2:32 PM 8/18/2017.
Red Tide Status (August 18, 2017)
The Florida red tide organism, Karenia brevis, was not detected in samples collected throughout Florida this week.
We continue to receive reports of a multi-species fish kill in Old Tampa Bay. Low dissolved oxygen associated with a bloom of the dinoflagellate Pyrodinium bahamense is likely the cause of this fish kill. Organisms affected include Lizardfish, Pufferfish, Flounder, Catfish, Trout, Blue Crabs, Snook, Mullet, Eels, and Stingrays.
Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tidespredict net offshore movement of surface waters and southern, onshore movement of subsurface waters from Pinellas to Lee counties 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|
