Florida Fish & Wildlife Red Tide Status: Friday, August 25, 2017
Florida Fish & Wildlife Conservation Commission red tide bulletin at 3:35 PM 8/25/2017.
Red Tide Status (August 25, 2017)
The Florida red tide organism, Karenia brevis, was not detected in samples collected statewide this week.
We have received reports of multi-species fish kills in the northern Indian River Lagoon, where patchy blooms of the dinoflagellate Pyrodinium bahamense have also been observed. Low dissolved oxygen is suspected to be the cause of the fish kills. We continue to monitor a bloom of P. bahamense in Old Tampa Bay, but have not received new reports of fish kills there.
Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tidespredict net onshore movement of surface waters and net offshore 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|
