Florida Fish & Wildlife Red Tide Status: Friday, May 5, 2017
FWC released the Red Tide Status Report this week.
Florida Fish & Wildlife Conservation Commission red tide bulletin at 3:27 PM 5/5/2017.
Red Tide Status (May 5, 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 to very low concentrations in four samples collected from Pinellas County; background concentrations in two samples collected from Manatee County; and background to very low concentrations in twelve samples collected from Sarasota County.
Two samples collected from the Northwest Coast (Bay and Gulf counties) contained background concentrations of K. brevis. Additional samples collected throughout Florida over the past week did not contain K. brevis.
Slight respiratory irritation was reported at Nokomis (Sarasota County) on 5/5. Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict net southern transport of surface waters and net southern, onshore movement of subsurface waters from Pinellas to northern Monroe 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|
