Florida Fish & Wildlife Red Tide Status: Friday, May 19, 2017
FWC released the Red Tide Status Report this week.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 2:49 PM 5/19/2017.
Red Tide Status (May 19, 2017)
The Florida red tide organism, Karenia brevis, persists at background to very low concentrations in Southwest Florida.
Over the past week, Karenia brevis was observed at background concentrations in three samples collected from Manatee County; background concentrations in one sample collected from Sarasota County; and very low concentrations in one sample collected from Charlotte County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Slight respiratory irritation was reported at Manatee Beach (Manatee County) on 5/18. Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict the northern movement of surface waters and minimal net transport of subsurface waters from Pinellas to Lee 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|
