Florida Fish & Wildlife Red Tide Status: Friday, February 10, 2017
FWC released the Red Tide Status Report as of this afternoon.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 3:10 PM 2/10/2017.
Red Tide Status (February 10, 2017)
A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from southern Pinellas to Lee counties.
Over the past week, Karenia brevis was observed at background to very low concentrations in two samples collected from Pinellas County; background to medium concentrations in nine samples collected from Manatee County; background to high concentrations in twenty-eight samples collected from Sarasota County; background to medium concentrations in five samples collected from Charlotte County; background to high concentrations in twelve samples collected from Lee County; and background concentrations in one sample collected from Collier County.
In northwest Florida, one sample collected from Gulf County and one from Franklin County each contained background concentrations of K. brevis.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Fish kills were reported along Siesta Key, Siesta Beach, and Nokomis (Sarasota County), and Bonita Beach (Lee County) over the past week. Respiratory irritation was reported along Lido Beach (Sarasota County). Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict net southern movement of surface waters and southern, onshore movement of subsurface waters from Pinellas to northern Monroe 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|
