Florida Fish & Wildlife Red Tide Status: Thursday, March 23, 2017
FWC released the Red Tide Status Report on Thursday this week.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 3:50 PM 3/23/2017.
Red Tide Status (March 23, 2017)
“A patchy bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from Pinellas to Lee counties.
Over the past week, Karenia brevis was observed at background to very low concentrations in three samples collected from Pinellas County; background to very low concentrations in six samples collected from Manatee County; background to medium concentrations in twenty-four samples collected from Sarasota County; very low concentrations in four samples collected from Charlotte County; and background to low concentrations in seventeen samples collected from Lee County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tidespredict net southern movement of surface waters and southern, onshore movement of subsurface waters from Pinellas to Collier counties over the next three days.
This week’s full Red Tide Status Report is being issued one day early; biweekly reporting (Wednesday and Friday) will resume next week.”
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|
