Florida Fish & Wildlife Red Tide Status: Friday, February 17, 2017
FWC released the Red Tide Status Report as of this afternoon.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 3:33 PM 2/17/2017.
Red Tide Status (February 17, 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 medium concentrations in eight samples collected from Pinellas County; background to medium concentrations in nine samples collected from Manatee County; very low to high concentrations in twenty-six samples collected from Sarasota County; background to medium concentrations in thirteen samples collected from Lee County; and background to very low concentrations in eight samples collected from Collier County.
Additional samples collected throughout Florida over the past week did not contain K. brevis. No samples from Charlotte County were analyzed this week.
Fish kills were reported at Manasota Key Beach (Charlotte County) over the past week. Respiratory irritation was reported in Sarasota County at Lido Key, Venice North Jetty, Venice Beach, and Manasota Beach, and in Charlotte County at Englewood, Manasota Key Beach, and Placida. 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|
