Florida Fish & Wildlife Red Tide Status: Friday, March 3, 2017
FWC released the Red Tide Status Report as of this afternoon.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 2:45 PM 3/3/2017.
Red Tide Status (March 3, 2017)
“A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from southern Pinellas to Collier counties.
Over the past week, Karenia brevis was observed at background to low concentrations in five samples collected from Pinellas County; background to medium concentrations in twenty samples collected from Manatee County; very low to medium concentrations in twenty-five samples collected from Sarasota County; very low to low concentrations in five samples collected from Charlotte County; background to low concentrations in twenty samples collected from Lee County; and background to low concentrations in eight samples collected from Collier County.
One sample collected from Bay County (Northwest Florida) contained background concentrations of K. brevis. Additional samples collected throughout Florida over the past week did not contain K. brevis.
Fish kills were last reported at Marco Island (Collier County) on 2/24 and 2/27. Respiratory irritation has been reported in Manatee County (at Manatee Beach), Sarasota County (Lido Key, Siesta Key, Venice North Jetty), and Charlotte County (Manasota Beach and Placida). Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tidespredict net southern, offshore 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|
